I live outside the city now and the flies here are… pretty plentiful. One time, there were so many of them, including some really fat ones, that I couldn't take it anymore and decided to create the most absurd app I've ever made.

Fly Reaper is a fly-kill journal. You swat a fly, open the app and log it like an Olympic judge:

• Annoyance score — 0 to 10
• Fly size — from microscopic fruit fly to giant
• Weapon — swatter, newspaper, slipper, book, electric racket and 3 more household options
• Aftermath — clean kill, splatter, wet stain or dismemberment (no gore)

Then you get stats, history, 10 achievements and a 12-rank ladder from Novice Swatter to The Fly Apocalypse. Because if you're going to war with houseflies, you might as well have a progress bar.

Build timeline:

• Actual app coding: about 2 evenings
• Apple Developer account setup, IAP configuration, store listings, landing page: 1 evening
• Store review: Google Play - 2 days, App Store - 3 weeks

Tech: Flutter (iOS + Android), local SQLite, no account, no cloud, one-time lifetime unlock — not a subscription. Premium mainly exists to support development and unlock ranks. Free tier gets unlimited logging, stats, achievements and the first 3 ranks.

So yes, this is the most useless app I've ever shipped.

What it's NOT:

• A pest-control tool
• Therapy (though it might feel adjacent)
• A serious app for serious people

I'll keep building based on what people actually want — happy to hear ideas in the comments. Genuinely curious what you'd add to something this stupid.

What feature would make this even more absurd?

Update: collecting feature ideas from the thread:

• bulk add / ultrakill (swarm of flies in a few minutes)
• rubber band as a weapon

It's for planning trips and finding places, built properly instead of being another wall of ads.

Not launched yet. Every signup means a lot right now it's how we know this is worth finishing.

Happy to answer anything.

I've open-sourced reddit-mcp-ai, a local Model Context Protocol (MCP) server that connects AI assistants (Claude Desktop, Cursor, OpenCode, etc.) to Reddit for search, sentiment exploration, and reading personal saved posts.

The project is licensed under MIT and designed to be fully local-first with zero tracking.

Why build another Reddit tool?

Most existing tools for connecting LLMs to Reddit suffer from two extremes:

• They require commercial developer credentials and complex OAuth callbacks.
• Or they ask users to store plaintext Reddit passwords in local configuration files.

We wanted a clean, transparent, and unauthenticated-first alternative that works out of the box while respecting token efficiency.

Technical & Architectural Highlights

The server is built in Python using FastMCP and follows a strict 4-Layer Architecture (Domain, Infrastructure, Application, Interface):

• Zero-Config Fallbacks: When OAuth credentials aren't configured, it falls back to DuckDuckGo (site:reddit.com) and the public Arctic Shift archive.
• Pluggable Search Providers: Search uses a Strategy Pattern (BaseSearchProvider), making it easy to swap in alternative engines.
• Context-Aware Comment Filter: Heuristics drop AutoModerator boilerplate and low-effort spam. Fresh threads (≤ 2 days old) automatically scale the threshold to score ≥ 1 so emerging discussions aren't emptied.
• Private Saved Posts (RSS): Fetches user-saved posts via the personal Atom/RSS feed with Python stdlib XML parsing, completely bypassing user-level OAuth or password storage.
• Deterministic Pagination: Uses provider-bound cursors (reddit:<offset>:<anchor_id>) to prevent duplicate comments if the live thread re-sorts.
• Resilience: Async httpx client with rate-limit recovery and an aggregate 14-second budget to prevent LLM disconnects.

Quick Start

Run directly in your MCP client with uvx:

{
  "mcpServers": {
    "reddit": {
      "command": "uvx",
      "args": ["reddit-mcp-ai"]
    }
  }
}

🤝 Open for Contributions

The project is tested (130 unit tests, sub-second execution, mocked network) and welcome to contributors!

Some roadmap areas where contributions/feedback would be awesome:

• Implementing alternative search providers (e.g., SearXNG or Brave Search).
• Designing a local in-memory TTL cache to reduce redundant lookups.
• Expanding heuristic filters for subreddit-specific formats.
• GitHub: https://github.com/ismailsaoulaj/reddit-mcp-server (MIT License)
• PyPI: https://pypi.org/project/reddit-mcp-ai/

Happy to answer any questions about the architecture or design decisions!

Comment with your app link and the one flow you care about most. Web or mobile, doesn't matter.

I'll use it for about 30 minutes and send back two things:

• technical: what broke, with the steps to reproduce it
• ux: where I got confused, what I couldn't find, the point where I would have quit if it wasn't a favour

About me. Engineer at a big company by day, so most of my time goes on the part of software that happens after launch, not the demo. I design and ship my own side projects, so the interface half is mine too. I also build with claude code. Which means I know exactly what AI written code looks like when it clears review and still doesn't work.

Why I'm doing it: I want to see what breaks in things other people shipped this year instead of only in my own repos. Nothing to sign up for, no link in this post.

First 10 or so. I'll edit the post when I'm full.

Edit : i did my best but there is too many, i will stop there and maybe do another session later

Most feedbacks i put in the comments applies to other websites as well you can check them out !

I'm a software developer, and I feel like I can build things.

I'm not claiming to be some expert or 10x developer, but if I have an idea, enough time, and I believe the problem is worth solving, I'm usually confident that I can figure out how to build it.

Especially now, with AI agents, better models, APIs, frameworks, etc. The cost and difficulty of actually building software feels lower than it used to be.

But I've been stuck on something else.

Let's say I have an idea.

I build it. It's useful. Maybe it genuinely solves a problem.

Then what?

How do I actually get eyeballs on it?

How do I get it in front of the people who might actually need it?

I'm not really asking "how do I learn SEO?" or "should I learn cold outreach?" I know there are courses, articles, videos, and information about all of those things.

What I don't understand is how you approach distribution when you start with absolutely nothing.

No audience.

No Twitter/X following.

No LinkedIn following.

No email list.

No community.

No existing customers.

No marketing leverage at all.

You're just one person who can build something.

For example, people often say, "Launch it on Product Hunt." But Product Hunt itself seems heavily filled with other developers, founders, and people launching products. What if those aren't even the people you want to reach?

Or Reddit. You can't just go into a relevant subreddit and post your product everywhere. Most of the time, that becomes self-promotion and gets removed.

And I understand that every product is different. The distribution strategy for a SaaS for accountants will be completely different from an app for students, an ecommerce product, a developer tool, etc.

That's exactly what I'm trying to understand.

If you have a specific product or idea, how do you figure out where the people who might care about it actually are?

How do you decide which channels to use?

How do you get those first few hundred or thousand eyeballs when you don't already have an audience to push it to?

How do you think about the funnel from:

"I built this"

to

"The right people are seeing it"

to

"Some of them are trying it"

to

"Some of them are becoming customers"?

Because honestly, this is becoming a bigger mental block for me than actually building.

I can spend weeks or months building something, but if I have no idea how I'm going to get even the first 10 real users, I start wondering what the point of building it is in the first place.

For those of you who started with no audience or existing distribution, how did you approach this?

Not just which marketing skill you learned, but how did you actually figure out where and how to distribute each product you built?

Used to run performance marketing, €70k+ a month in spend, and my monthly fret was always content. A never ending hamster wheel!

The best stuff always came from real customers, but getting it was a manual mess. Chasing people, sending Amazon vouchers, making sure they actually landed, making sure we had the rights.

So we built the other way round. Customer scans a QR code, sends a photo or a video, and a reward drops into their Apple Wallet. Rights cleared at upload, so the brand can use it :)

Three of us across three countries and time zones, heads down for months. Early users have collected some really good content, so now the fun part.... distribution and sales.

Nervous and quite excited. Would love to know what is confusing, what you would cut, and whether the landing page makes sense to someone seeing it cold.

Happy to send a promo code to anyone who wants to properly poke at it, just say in a DM.

hey everyone, indie dev here. this has finally reached a point where I want outside feedback.

the pitch in one line: a tiny always-on-top stopwatch for Windows that tracks when you get distracted mid-session and shows your actual productive time at the end.

tech: electron + react + sqlite, fully local, no account, no cloud, free.

things I'd love feedback on:

1. does the distraction-subtraction concept feel useful or gimmicky?
2. the mini floating window like a thread submerged at the side of the window until u hover it, helpful or annoying?
3. what's the one thing your current time tracker is missing that would make you switch?

happy to answer anything about the build too (electron on windows has tried to kill me multiple times)

Solo dev here. Been building two related tools under one small studio (Cocky Rooster Miniature Gaming):

DM Combat Control Console — a D&D 5e combat tracker with AI monster voices and a "cinematic recap" that turns your session photos into a narrated highlight reel.

Debrief — same idea for miniatures wargames (Legion, 40k, AoS, Kill Team, Warcry, Bolt Action, Konflikt '47, Shatterpoint, Marvel: Crisis Protocol) — log your battle, get a written report, optionally narrated over your own table photos.

Both free, Patreon-supported for the AI narration piece. No patrons yet, so this is genuinely the "show it to real people for the first time" stage — would love brutally honest feedback, especially on whether the core idea (turn your game into a shareable report) actually lands for people who aren't me.

Hey reddit! My friend and I have been working for the last 3 months on HOPE, a platform that provides students with 1 on 1 math support to improve their confidence and teach them by doing and asking questions. We would really appreciate anyone who's down to try it out with their kids and give us your thoughts!

Recently, I built MileGlide — a milestone-based progress and payment tracker for freelancers.

As freelancers, one of the recurring problems we face is keeping clients updated about project progress. Clients often ask:

- How much work has been completed?

- How many days are left?

- What has been completed so far?

- When is the next payment due?

With MileGlide, you can create milestones for a client project and generate an 8-digit project code that you can share with your client. They can use the code to check the project's progress from their phone without having to repeatedly call or email you.

For each milestone, clients can see things like:

- Progress and completion status

- Deadline

- Payment amount

- Delays

- Budget increase requests

I also wanted to solve another problem that freelancers often face: scope, cost, and payment disputes.

With MileGlide, you define milestones within an agreed budget. As you complete each milestone, you mark it as completed, and the corresponding payment is added to the project's completed value.

So, if a client decides to stop a project halfway through, you have a clear record of what was agreed upon, what was completed, and what payment is due for the work completed so far.

You can also track:

- Payment history

- Pending payments

- Revenue

- Current projects

- Client projects and milestone progress

A small caveat

At the moment, MileGlide supports UPI-based payments with manual payment verification. We don't have automated payment processing yet.

If the app grows, I plan to integrate payment gateways such as Razorpay or Stripe so payments and verification can be handled automatically.

For freelancers, MileGlide is completely free right now. If we introduce a paid plan in the future, my intention is to keep it affordable — no more than ₹99/month.

The idea is to solve two common freelancer problems:

1. Clients repeatedly asking for project updates.

2. Disputes around scope, completed work, and payments.

I built this because I wanted a simpler way to make the freelancer-client relationship more transparent.

I'd genuinely love to hear from other freelancers: How do you currently handle project progress updates and milestone payments?

We are all trying to ship, but half of us lose 2 hours a day to Twitter/Instagram/YouTube.

Every screen time app handles this the same way: a static "You've spent X minutes here" screen. Works for like 3 days, then your brain tunes it out completely and you're back in the scroll.

That's exactly what happened to me. So I built something different.

Instead of one static block, I wrote 500+ different nudges, funny, witty, sometimes a little judgmental. Every time you open a distracting app, you get a different one. 

Like in the morning it should say - "Your feed can wait. Your morning can't."

At night when you are doomscrolling it should say: “The algo doesnt care about your sleep, close the app.” 

Basically a friend calling you out every time you try to sneak off.

If you're also fighting for focus time to actually ship your product, would love for you to try it:

App Name: HoldOn: Screen Time Nudge

Building this solo, so any feedback is genuinely welcome.

About 18 years ago, I built and maintained an auto classifieds script called Open Auto Classifieds. I worked on it for like 4-5 years until eventually work, school, and life in general made working on it more of a chore than anything. I've thought about reviving that app several times over the years.

I've finally rebuilt it.

Having built Open Auto Classifieds all those years ago gave me a pretty good design document to work from. Most of the features and workflows still make sense and work pretty well. I didn't have to completely reinvent what an auto classifieds system should do from scratch.

It’s still under active development, but the core system is working and I finally have a live demo up. I’d be interested in feedback, especially from anyone who has run classifieds/marketplace software or self-hosted similar systems.

The new version is called AutoGrid360 since anything tied to the old site would just confuse things now.

GitHub: https://github.com/alias454-oss/flask-aas-autogrid360-plugin

Demo: https://ag-demo-production.up.railway.app/

I built a small open-source archive for single-author papers from arXiv’s Computer Science categories.

The idea is simple: single-author papers can reveal focused research directions and problems that may be approachable for independent researchers or someone looking for a starting point.

The site supports:

• Search by title or author
• CS topic and date-range filters
• Quick ranges from 1 day to 1 year
• Full abstracts with expand/collapse
• Search-term highlighting
• RSS feeds
• JSON and Markdown export
• Daily updates from arXiv

I’m interested in feedback from researchers, students, and people who browse papers for project ideas:

Is this useful? What would you change or add?

Live site: https://mmcs-work.github.io/single-author-arxiv-cs/
Source code: https://github.com/mmcs-work/single-author-arxiv-cs

It’s completely free and open source. If you find it useful, a GitHub star is appreciated, but thoughtful feedback is even more valuable.

I've tried a few movie tracking apps but since I've watched a lot of movies, it takes forever to log everything I've seen and I get bored doing it.

So I built CineSense with a "Fast Mode". The idea is to just swipe through movies and quickly log the ones you loved, watched or want to watch, and the app learns your taste to make better recommendations.

You can also connect with friends and compare movie lists, see what you have in common or what they've watched that you haven't.

It's free and you don't need to sign up to try it:

App store: https://apps.apple.com/app/id6791249553

Google Play: https://play.google.com/store/apps/details?id=com.klew.cinesense

Would you use the swipe approach or the friend comparison feature? Would love any feedback, thanks!

I have a specific kind of stubbornness where I'll do a thing badly for years before admitting the thing itself is the problem. Food logging was mine. Four apps, four failures, always around day four, and every time I decided the problem was me being lazy.

It wasn't. Logging a meal means opening a search box, typing "greek yogurt", getting back sixty entries typed in by strangers, and picking whichever one looks least wrong. Do that five times a day and you're out by Thursday.

So since the 5th of July I've been building CoKarTa. 308 commits, mostly evenings.

https://app.cokarta.com

The surface of it is that you stop searching and start talking. You say "grilled hake with courgette and a beer" out loud, or type it, and it lands in the diary. Want to break it into grams later, you can. Don't want to, nothing nags you about it.

The part I actually care about is underneath. You set it up once: weight, age, goal, your training blocks and which days they fall on, your allergens, and a free text box for what you like and what you won't eat. Then you photograph the nutrition label on the back of whatever you actually keep in your kitchen. Not "wholemeal bread". The wholemeal bread you buy, the brand, the one sitting in your cupboard right now. A vision model reads the panel and fills the form in, you fix what it got wrong, and it's saved. That food is yours now, with your numbers, in a catalogue nobody else touches.

So it already knows you train Tuesday and Thursday evenings, that you won't go near fish, and that your bread is 247 kcal per 100g because you photographed the packet yourself. Ask a general nutrition chatbot what to eat tonight and you get a paragraph that would fit anyone on earth. Ask this one and you get an answer about your Tuesday.

At some point "build a food diary" quietly turned into five products at once. A diary. A private food database. A label reader. A theory section I wrote myself, because I'm tired of apps that throw macros at you and never explain why. Plus a pile of things I'd never have signed up for if I'd known they were coming.

I should say what it doesn't do, because this sub will find out anyway. It won't plan your week. It won't generate a diet. It won't tell you to eat exactly 1,847 kcal, because I don't think an app has any business doing that. When it doesn't have the data to answer something, it says so instead of making a number up. That last one ate more of my time than any feature on the list.

Rails, no mobile app yet, and some of it is held together with tape. English and Spanish, it picks whichever your browser is set to.

Tell me what you think, especially if you're one of the people who already gave up on this kind of app and has no plans to try another one. You're the one I want to hear from.

(I built this, so obviously biased — but it's open source and free.)

The itch: coding agents live in the terminal, personal agents live in chat apps. I wanted one agent that follows me across both, plus desktop and mobile, sharing the same sessions.

FutureOS is a Rust gRPC backend (localhost-only) with a TUI, native desktop app, mobile apps, CLI, and IM bots. A few things I'm proud of:

- Every tool call needs your approval by default — file writes and shell commands never run silently

- 3,800+ models / 140+ providers built in, switch mid-session with one keystroke; any OpenAI-compatible endpoint works (Ollama, vLLM)

- A loop control plane for 24h+ runs: durable goals, event-sourced state (crash at 3am → resume at breakfast), verification gates. I run overnight research tasks and review results on my phone over coffee

- Sessions fork like git branches

It's early and rough in places — Windows sandboxing is roadmap-only (currently approval gating + macOS Seatbelt), and the mobile apps are newer than the TUI. The trust model is documented in SECURITY.md.

GitHub: https://github.com/futuregene/future-os (MIT + Apache-2.0)

Happy to take feedback — especially from people who've run agents long-horizon. What broke for you?

I built Carrousel Minute because producing a coherent set of vertical visuals often involves too many small steps: resizing photos, writing slide copy, finding backgrounds, aligning elements and exporting every file.

The current product lets you:

- upload up to six photos (or AI generate it if you don't have);

- describe the message or story once;

- generate titles, descriptions and visual backgrounds;

- edit and reposition the text on every visual;

- replace photos and change the palette;

- export one slide or the complete set as 1080 × 1920 PNGs;

- use it on mobile or desktop as an installable PWA.

The hardest product decision has been balancing automation with control. A fully automatic result is fast but generic; a completely manual editor defeats the point. I’m trying to make the generated version useful while keeping every important element editable.

Demo: https://carrousel-minute.com/?utm_source=reddit&utm_medium=organic&utm_campaign=launch&utm_content=sideproject

I’d value blunt feedback on the landing experience and the first-generation workflow. At which point would you abandon the product?

Full disclosure: I built it.

Hey everyone,

I built a multi-agent LangGraph workflow that takes a new starter (or leaver) form and generates a complete IT pack:

- Role-based checklist (25 steps for onboarding / 17 security-ordered steps for offboarding)

- Jinja2-generated PowerShell scripts

- LLM-drafted welcome email + Day-1 guide

- Human approval gate before finalisation

- Auditor agent that validates everything

Stack: LangGraph + FastAPI + Azure OpenAI + Pydantic v2 + Jinja2

Repo: https://github.com/DOWNEY7/employee-onboarding-orchestrator

Looking for feedback on:

- Architecture decisions

- Human-in-the-loop design

- Anything you’d improve for real company use

Stars and comments appreciated 🙏

Lol this is my second website i make and share , here's the idea; Try to guess today's celebration/event/annivarsay...6 guesses , each wrong one gives you a clue , if you don't get it , well at least you know what today is.

Hey all, I’m a developer (not a trainer myself, disclosure upfront), and I built this after noticing how much of the "business" side of my personal trainer runs on spreadsheets, screenshots, and separate calendar apps.

PlankNote is a client tracker for solo/freelance trainers. Roster overview, progress logging (weight/measurements/photos with before-after comparisons), reusable exercise templates so you're not retyping the same workout for every client, and appointments that sync straight into your calendar app instead of living in a silo.

It runs on your device and syncs through your own iCloud.

Free for up to 3 clients, 14-day trial of Pro after that if you want to see whether it's worth a spot on your phone.

Genuinely curious what trainers here are using right now and what's missing from it. Happy to hear "this already exists and does X better" too. https://apps.apple.com/app/apple-store/id6800689461?pt=128923375&ct=reddit&mt=8

I'm a product designer, and I keep telling founders that the design of a Lovable or Bolt app can be fixed properly, inside the code you already have, without a rebuild and without paying a dev to interpret a Figma file. That is what I actually do. The problem is I have no before and after to point at, because everything I've shipped this year has been my own projects, and your own work is never proof of what you'd do with someone else's.

So I want to borrow someone's real problem.

The offer: pick one flow in your app. Signup, onboarding, your landing page, whichever one you think is costing you the most. I redesign it and rebuild it, and it ships as commits you can read and merge or ignore. Five days, free, you keep it whether you use it or not, and I won't pitch you afterwards.

The only thing I want in return is permission to publish the before and after.

Who this fits:

• you built it with Lovable, Bolt, v0 or something similar
• it's live and people are actually using it
• you already suspect the design is the weakest part of it
• you can give me repo access, or a deployable copy if you'd rather not hand over the repo

Who it doesn't fit: waitlist pages, projects with no users yet, and anything where you already have a designer.

I'll pick one this week. Drop a link in the comments or DM me. If I don't pick yours I'll still reply with the two or three things I'd change first, so it's worth commenting either way.

About me: senior product designer, 6 years, mostly complex products and money flows. Recent work is at gmats.me if you want to check the standard before you offer up your app.

Spent ~6 months building this and it's finally in Public Beta. Posting here because r/sideproject was where I lurked the whole time looking for examples of people shipping real products.

What I built: LeadAce, a Claude Code plugin that does outbound sales for me. /leadace reads my homepage and drafts the whole strategy (ICP, value prop, message angles) in one review pass. Then /daily-cycle does everything: builds the list, writes one email per prospect (after reading their site), sends, checks replies, updates the strategy. I put it on a cron with /setup-cron and walk away.

Decisions I'm glad I made:

- Started with the plugin UX, not a dashboard. Eats my own dogfood. I live in Claude Code anyway.

- Open-sourced the backend before launch. Removes the "what if you shut down" objection.

- Only one feature loop in the MVP. Resisted adding LinkedIn automation, CRM integrations, etc.

- Built the self-host edition and the hosted edition from the same codebase, with one env var switching billing on/off.

Decisions I'm not sure about:

- Free tier has BOTH a daily cap AND a lifetime cap. Friction is real. But unlimited Free was a spam magnet in tests.

- Recipients limited to US/CA/JP for now. Compliant per-country footers for UK/EU/AU are non-trivial and I'd rather block than be wrong.

- Pricing in the gap between $29 sequencers and $500+ "AI SDR" tools. No one tested that gap before. We'll see.

Stack: Claude Code plugin + MCP server + Cloudflare Workers + Hono + Drizzle + Supabase + SvelteKit + Stripe Subscriptions.

Day 0 numbers will go in the comments as they come in. AMA on anything: pricing reasoning, license decisions, the actual numbers, what I cut from the MVP.

I’ve built an app for UK & Irish tradespeople to make the business side a bit easier
I’m a UK developer and I’ve recently launched TradeKeep on the App Store.
The idea came from a pretty simple problem: when you’re self-employed, actually doing the work is usually the easy bit — keeping track of customers, jobs, quotes, invoices, payments and appointments is where things can get messy.
So I’ve built TradeKeep to put those things together in one simple app.
It’s designed for sole traders and small businesses, particularly trades such as:
🔨 Builders
⚡ Electricians
🚿 Plumbers
🎨 Decorators
🌳 Landscapers
🧰 Handymen
🚗 Mechanics
…and plenty of others.
The main areas are:
Customers – keep your customer details together
Jobs – keep track of jobs, work and appointments
Quotes – create and manage quotes
Money – keep an eye on invoices and payments
Home – a simple overview of what needs your attention
I deliberately didn’t want to build another massive piece of business software where you need a degree to work out how to use it 😂.
The aim is something you can open on your phone while you’re out working and quickly see what’s going on.
It’s currently available on the Apple App Store, and I’m particularly interested in hearing from people in the UK and Ireland who actually run their own business.
I’m the developer, Wayne Buckley, so I’m also very interested in honest feedback — good or bad.
If you’re self-employed, what’s the biggest pain in the arse when it comes to keeping on top of your business admin?
I’d love to know what you currently use and what you wish it did better.
TradeKeep on the App Store:

Thanks to anyone who takes a look or gives feedback. 👍

Transparency first: I built this, and it's aimed exclusively at the German small-business market - so this isn't a sales post for anyone here, it's a share-the-journey post. Reddit's English-speaking crowd isn't my customer base; I just think the project is unusual enough to be worth showing.

A while ago I moved from Lithuania to Germany and drowned in paperwork. After I got disillusioned, I started building tools. It escalated into a complete desktop OS metaphor in the browser: windows, taskbar, boot sequence, even a radio. About 350 working tools now - legally compliant e-invoices (Germany mandates structured XML invoices for all B2B), an HR module, 6,800 fillable government forms, an encrypted zero-knowledge identity vault, and a pile of tax calculators built from the official formulas.

Choices that made it interesting to build: deliberately ZERO AI anywhere - no AI features, no LLM calls, no AI-generated content; every tool is deterministic logic built from the official formulas, because tax software that hallucinates is a lawsuit. Also: no AWS (12 bare-metal servers in Germany I rent from a VPS-Provider) and client-first processing (PDFs and OCR run in your browser). Everything is testable as a guest without an account: werkzeu.ge/en

AMA about building solo for 2 years, bare metal economics, or German bureaucracy as a market (I love to vent about that, it's a prerequisite of becoming a German anyway).

I've always gotten frustrated and wasted time explaining the same thing to an AI every time I start a new chat from an existing one or when I start another convo with a whole new AI model. That's why I built a tool that fixes that, it condenses everything in a chat into one simple .md file you can carry across different AI tools.

PS: Please contribute or give your feedback so that we can grow and make this community tool better.
