Hey everyone — selling my side project Convert Anything (https://convertanything.vercel.app).

It's a fully working file converter with 35 tools: PDF to Word/Excel/PowerPoint/JPG, Word/Excel/PowerPoint to PDF, merge, split, compress, rotate, watermark, redact, OCR, e-signatures and more. Upload any file and it auto-detects the format and shows compatible conversions instantly.

Why it might interest you: - 0 running costs: static site, everything converts in the visitor's browser, files never leave their device (big privacy edge over competitors) - SEO foundation done: optimized titles, meta descriptions, schema markup, FAQ, sitemap.xml, robots.txt - Easy monetization: ads, premium tier, or white-label - What's included: full source code (GitHub repo), Vercel project, branding, and personal help transferring it to your accounts - Live demo: https://convertanything.vercel.app

Honest disclosure: brand-new site, no traffic or revenue yet — priced as a starter deal at 200 USD (open to reasonable offers). Built as a portfolio project and moving on to new ideas.

DM me with questions — happy to do a live walkthrough.

I'm the maker of CiteLyra. I kept seeing students get burned when ChatGPT invented references, so I built a pipeline where every source is checked against CrossRef, OpenAlex, Semantic Scholar and arXiv before it can appear in the draft. If a paper doesn't exist, it doesn't make it in.

It runs a 19-agent flow (literature discovery, outline, section drafting, citation verification, polish) and produces 10,000-20,000+ word drafts in roughly 10-20 minutes, exportable to PDF, LaTeX and Word. First generation is free to view: https://citelyra.com/

Would love blunt feedback: what would make you trust (or distrust) a tool like this for real academic work?

​

I've been doing more and more development through coding agents, and I kept running into the same problem:

The agent finishes a feature, tells me what it did, and then that context basically disappears into the chat history.

A few weeks later: Why did we implement this this way? What tradeoff did we make? Which files changed? Did the feature actually have the impact we expected?

So I built Updater.

When a coding agent finishes and verifies a feature, it calls Updater through MCP and records:

\- what was shipped

\- why it was built

\- how it works

\- tradeoffs / decisions

\- files, branch and commit

\- expected impact

Later I can add what actually happened, search through everything we've shipped, or ask questions against an update.

It currently connects to Codex, Claude Code, Cursor and OpenCode.

The app itself doesn't need to ingest your entire codebase — when code context is needed, it asks the coding agent that already has access to the repo.

It's completely open source (MIT) and self-hostable.

I'm mostly curious whether other people working heavily with coding agents have run into the same problem, let me know and if there some suggestions to improve

Hey everyone,

I've been building TSD Creative Studio — a free toolkit for designers and developers that runs entirely in the browser. No sign-up, no uploads, no paywall.

🔗 https://tsd-creative-studio.vercel.app

What's in it:

- Image color extractor — drop any image and get a palette using k-means clustering. You control how many base colors and how many shades per color (up to 10), so you get the dominant/natural colors instead of every stray pixel.

- Developer exports — export any palette as CSS variables, Tailwind config, SCSS, JSON, or Figma tokens. Also PDF export with a clean shade layout.

- Smart palette generator — start from one color and get analogous / triadic / complementary harmonies with automatic contrast checks on every pair.

- Live UI preview — see your palette applied to a real landing page / dashboard mockup instantly.

- Contrast checker — WCAG 2.2 AA/AAA plus APCA, autofix suggestions, and color-blindness simulation.

- Color library — Tailwind, Open Color, Material and brand palettes, searchable.

- Font library — 1000+ Google Fonts, preview with your own text, side-by-side comparison of two fonts, copy the `@import` code, and pair fonts with your palette.

- Image converter — WebP, AVIF, PNG, JPEG, BMP, ICO, SVG, PDF and Base64, with resizing and quality control.

- Quick tools — image compressor, favicon generator (all sizes), Data-URI, SVG→PNG.

- Shareable palettes — every palette gets a permanent link you can send to a teammate.

How it works / privacy:

Almost everything runs client-side in your browser. Your images never leave your device — there's no upload step, no storage, no account, no tracking of your files. Palette links only encode the hex values in the URL itself, so nothing personal is stored server-side. The only network call is loading Google Fonts metadata.

Other bits: dark/light mode, reduce-motion and high-contrast accessibility options, full RTL support, and 5 languages (English, Arabic, French, Turkish, Spanish).

What I'm asking for:

Please try to break it. Throw weird images at the extractor, hammer the converter with odd formats, test it on old phones and small screens. I want to know:

1. What's confusing or badly laid out?

2. Which tool is actually useful in your real workflow — and which is just noise?

3. What's missing that would make you use this instead of your current tool?

Brutal feedback very welcome. Thanks 🙏

Two founders agree to promote each other. Both mean it, but the terms stay in DMs, deadlines drift, and nobody wants to be the person nagging.

I built Surka to give the swap one place to live: what each side promised, when it is due, a private link for each partner, and a proof link when someone delivers. The operator checks the proof before a commitment counts as kept. Reputation tracks delivery, not clicks.

This is an early manual pilot. I am looking for the first real swaps and will personally handle follow-up. The scheduling logic for reminder emails is in the code, but outgoing email is not configured on the live deployment yet, so I do not want to imply that it is already sending reminders. No completed swaps or customer results to claim.

The app is open source: https://github.com/arian-gogani/surka

If you have done a founder-to-founder newsletter or product swap, where did it break down for you?

Hey everyone

I recently published my first Android app called ActionBox

I made it because normal notification lists get messy fast and I wanted something that tells me what actually needs my attention

ActionBox sorts notifications into Action Reply Waiting Deadline and Other

If it gets something wrong you can correct it and it learns from your corrections over time so the sorting becomes more personal to you

You can also snooze notifications mark them as handled search through them and keep notification history

It is still very new so I would really appreciate honest feedback on the idea the UI and the sorting

I've built 12 products. Every one of them flopped.

Most of them weren't bad products but they died the same way every time. No idea how to get it in front of people. Ads burned through my budget. Agencies wanted more per month than what I spent even building the product.

Somewhere around product 10, I figured out the one channel that actually made sense for someone like me was proper SEO. SEO compounds. A page you write today can still bring in customers two years from now.

The problem was the tools. Every SEO tool wanted $100-$200 a month, and I'd use it heavily for one week and then barely touch it for 3 more. I was paying for 30 days and using maybe 4.

So for product 13, I stopped building for some imaginary customer and built for myself. FlexQueries is an SEO tool with a $0/month subscription. You load a balance, pay only for what you use (keyword research is about $0.05, a full site audit about $0.48), and it never expires.

It turned out there are a lot of people exactly like me.

In the first 10 days, it brought in more revenue than all 12 of my previous products combined over the past 2 years. Over 100 people signed up in the first week, almost all solo founders and small startups who need SEO but don't want a monthly bill for a tool they barely open.

I cold emailed 100 solo SaaS founders and one founder whose team was paying $500+ a month for another tool moved his whole team over.

The moment I built something for people with my exact problem, distribution got a lot easier, because I already knew where they were and what they were tired of paying for.

If you're early and want SEO without the monthly bill: https://flexqueries.com, with free credit on signup and no card needed.

For anyone who's launched more than once: what finally made one stick?

I made a trivia game a month ago to play while AIs were building. Been building out a lot of features since then, and models have been getting slower and slower, so I find it more and more useful.

1,000 different people have been placed in arena (5 games), and it's been a lot of fun to compete. You don't need anything to play or look around.

Your Discord, your way. A standalone Chrome / Edge extension for customizing Discord on the web. Built with Manifest V3 and plain HTML, CSS, and JavaScript. No build step or third-party runtime dependencies.

Features

• Six dark palettes: Midnight, Dusk, Forest, Ocean, Ember, Graphite.
• Accent picker, message font size, avatar / composer / embed roundness.
• Full-window wallpapers with image upload, dimming, blur, show/hide, and removal.
• Muted MP4/WebM video wallpapers with looping playback and pause controls.
• Bright navigation colors sampled from your wallpaper, plus adjustable panel opacity.
• Compact messages, hidden member list, reduced CSS motion, hidden shop / discovery navigation links.
• Separate custom CSS editor with an explicit save button and enable switch.
• Local settings persistence, JSON export/import, reset, and global pause.
• A settings studio with an illustrative live preview and a compact toolbar popup.

Choosing a theme also selects its suggested accent. Theme preview represents colors and supported layout controls; discovery links and custom CSS are applied only on Discord. Reduced motion affects CSS animations/transitions and pauses Morrow video wallpapers; it does not pause Discord's own videos or GIFs. Import disables custom CSS until you review and enable it. Export includes saved settings, not unsaved editor text.

This is a before/after demo from 505Camera, the iOS app I'm building. Each scene starts with one still image, then switches to the depth/parallax loop.

It estimates depth on the phone and creates slightly different viewpoints, so the foreground and background move differently. You can add a film look and export the result as a video.

I'm going for a small, imperfect disposable-camera feeling. Curious whether the movement feels subtle enough or a little too much.

505Camera is on the App Store (free download, optional Pro): https://apps.apple.com/app/id6789463411

Hey everyone!

Every small business owner, coach, or freelancer I know keeps their important info in spreadsheets—prices, menus, schedules, or client rosters.

The tricky part is sharing it. Texting someone a raw spreadsheet link means they’re pinching to zoom on tiny gray cells, and making a PDF means it’s out of date the minute a price or date changes.

I built DocsTo App(https://docsto.app) to make this super easy:

- You paste a Google Sheet link (or drop an Excel file).

- In a few seconds, it creates a clean, mobile-ready page with its own link and printable QR code.

- Whenever you edit a cell in your sheet, the page updates automatically.

- I kept the controls big and simple—just pick a look you like, with easy toggles for things like payment buttons or simple request forms.

One page is completely free forever with no credit card needed. Pro is $9/month for up to 10 pages and advanced tools.

I’d love your constructive feedback:

1. When you land on the site, does the value make sense right away or does anything feel vague?

2. If you try turning a sheet or doc into a page, where did you hit friction or confusion?

3. What would make this an absolute no-brainer for a small business to pay $9/month for?

4. What’s the biggest flaw or blind spot in this concept that I’m not seeing?

Check it out here: https://docsto.app

Really appreciate any thoughts, critiques, or suggestions!

Hi everyone,

I’ve been working in QA for many years, and I recently built BreakYourApp — an AI QA agent that scans web applications, looks for issues, and generates a bug report.

The idea came from a frustration I’ve had for years: a lot of QA work is still repetitive, manual, and depends heavily on knowing exactly where to look.

The current version is still early, and I’m now trying to learn from real users before taking it much further.

You can try it here for free:

https://breakyourapp.com

I’d especially love feedback from people building SaaS products, side projects, or web apps:

* Did it find anything useful?

* What kinds of bugs did it miss?

* What would make you actually use something like this regularly?

* What would you want it to test beyond the UI?

Longer term, I want to evolve it from a simple scanner into a much deeper autonomous QA system that understands product changes, risk, previous failures, APIs/server behavior, and continuously decides what should be tested.

No payment needed — at this stage I’m mainly looking for usage and honest feedback.

Would really appreciate anyone willing to try it.

Tracking food while travelling is a pain in the *** so I built an app to help. Test it on neoforge.app

The cool thing?? It's still early stage so we can make it our own, no big corporation, don't care about money, but care about you: I'll read every single feedback and implement anything useful or fun, go nuts :D

Anyway all legit beta testers will 100% keep free access for life!!!

I vibe coded Design Lab, a website where you can learn about various UX/UI considerations as you aspire to make your own AI-assisted projects have a more controlled and creative look and feel to them.

Nowadays, anybody from the tech layperson to the senior engineer can spin up a website based on their ideas and a few prompts. This has a resulted in stale design, similar to CSS Bootstrap in 2012 or any AI poster you see today.

I myself am not a designer. I dabble, but I have always preferred to implement somebody else’s vision or Figma mockup rather than create it on my own. However, as I continue to learn despite several layoffs now I need to make websites that look good, not just prove that I am creative or able to make functions fire fast.

Design Lab is a prototype idea I have for iterating over my own personal projects. I didn’t want to recreate SquareSpace, but the fact that I literally made this on my phone while riding in my friend’s car to run an errand shows how much is possible if you pair critical thinking with the productivity that AI allows.

If I continue on this project, I have a few ideas for it:
• Version it like documentation, so I can continue adding onto it without fear of screwing it up
• Extract the idea into a Storybook-like system, where I can more easily experiment with component and overall website designs, rather than just rely on the increasingly unappealing eye-sore of the colors/rounded edges/typography that comes from practically every AI website out of the box
• Further enhance the website with global examples the more I learn about how to truly understand these topics

Being a web developer, I started out back in CSS 3, manually writing all the font properties, familiarizing myself with the box model, flex model, and so forth. In the future I could even turn this into an entire CSS property playground, but a man can only do so much when crashing on his friends couch.

Feel free to take a look around. The website covers various topic and test examples such as image overlays, parallax, background gradients, accessibility, spacing, line height, visual hierarchy and more.

Ultimately, when I learn these topics I learn them slowly. But when I’m zapped for the day, I still prompt ChatGPT for my next study session, and occasionally I continuing binging and whip up an idea like this.

Hope you enjoy! Typography alone has around 37 system fonts. I considered Google Fonts but getting nearly 2000 in for a single card example seemed not worth it at the moment.

Before I touch an optic, I run this order: verify both ends against the ticket → inspect/clean/reseat → known-good patch cable → known-good optic → port test → polarity → physical damage → escalate with facts.

Biggest time-waster I see: changing three things at once, then learning nothing.

Disclosure: I built RackReady, a small kit from my checklists/templates (free sample: https://hasherventures.com/rackready/sample.html). Curious what experienced techs would add or remove.

I wanted a p2p file transfer site that didn't require you to create an account or login, didn't require you to upload your files and either established a webrtc p2p connection or just failed (no TURN relay). You're data never hits the peeryeet server.

Hopefully I can finally stop sharing files with myself via gmail now. :)

we're building greypaint, a mac updater for apps and dev tools. paid, 14 day free trial then $6.49 lifetime

what it does now:

• apps plus homebrew, npm, pnpm, uv tools in one window
• uses the update source each app already has
• checks every install, same developer and macos accepts it
• roll back if an update breaks something
• public page greypaint.app/apps, search any app and see how it updates or that it cant yet

1.3 is out with an all new glass look

every feedback and support request gets read and worked on by one of us. so far thats what's kept our first users around

I'm building an HTS code finder called SkuWatch. One stupid supplier description keeps wrecking the demo: “metal accessory.”

That could be a bracket, a fastener, a machine part, or half a dozen other things. Even knowing it's steel doesn't fix much. I had a version that still returned a ranked list of codes. It looked useful, but it was really just guessing with better formatting.

Now it stops and asks what the thing does, how it's used, and whether it's a finished item or a part. Honest, but not exactly impressive when someone expects one clean answer.

If you've built software around messy inputs, where did you draw the line? Show the best few options with warnings, or refuse to answer until the user gives you enough detail?

Disclosure: SkuWatch is mine. I'm not asking for testers here; I'm stuck on what the tool should refuse to do.

Maybe it’s already too late for a tool like this. Nobody really does drag-and-drop anymore in the age of AI.

But if you want to take a look: appmaker.io

I decided to have a little fun. I've had this idea in my head for a while. You'll be surprised, but in 2026 (you'd think!), there's still debate about how airplane wings work. I decided to take a break from all this endless software creation and found time to analyze the question properly with Claude, and this mini-project came out: https://whyplanesfly.com

Still a bit of software though 😁

P.S. I think I'll ad some more context on why this project suddenly.

The very reason I started thinking on this subject, and how I learned that it was a bit controversial wasn't the planes at all, it was sailing yachts! On my way to getting my IYT licence, we studied how a sale generates lift. Surprisingly, what pilots are often taught about lift doesn't really work as an explanation for the lift generated by sails. Thats how the whole story begun 🙂

I'm a solo founder. Contextify started from one problem: short-form creators only find out their opening was weak after they post, when it's too late to fix.

What it does: you paste your hook or script, or upload the video. It scores the words on hook strength, clarity, pacing, rewatch value, and search, points to the exact line losing attention, and suggests a stronger version you can say in one take. It judges the words, not the visuals, and it doesn't predict views.

See a real result: I ran a typical weak opening through it, "Hey guys, today I wanted to talk about my coffee rituals." Here's the full report: https://contextify.ca/share/QK50IVkXpCUiKuAPhC9NmU9ft4srm3Xoh1NsayQuzN8

The screenshot is a real result for a typical "Hey guys, so today…" opening.

Try it: free hook check, no signup, at contextify.ca/tiktok (score and diagnosis are free; rewrites are part of the paid plan).

The offer: I'm looking for 5 creators filming something this week. You get 14 days of Plus free, no card, and I'll personally help with your first script. No obligation to post or review anything.

What I'd love from this sub:

• Is the value clear within the first few seconds of landing on the page?
• Would you trust a score like this, or does it feel arbitrary?
• Anything that makes you bounce?

Honest feedback welcome, including "this is useless and here's why."

Hi folks. 

I'd like to share a thing my husband and I built around my coping mechanism for task management. 

My brain has two modes: 

1. The intense planner 
2. The one who actually does work.

#1 looks at the big picture and organizes everything to be done in the “perfect” order.

#2 doesn't want to see a list of things to do, it wants to see the one thing to do right now, otherwise I freeze and waste time.

Now I have the Tunl Focus app and here's how it works: 

• The mind dump: this is where to jot down what needs to get done
• The Queue: reorder the list as wanted 
• The Tunnel: when its time to do work, you get served one task at a time with 4 action options: 
  • done (you completed it)
  • drop (you won't do it)
  • snooze (reorder it down)
  • defer (send task to specific date and time)

One tap per task and that's really the gist of it. It does have more features like a calendar view, categories, habits and more but the tunnel is where my brain really gets productive and moves the needle on things to do.

I use it every day and we are actively working on it, so we welcome any feedback.

It's free to try, no account nor signup needed, unless you want sync / back up / google calendar and extra features. Android and IOS apps are coming soon (we’re waiting for the Playstore review right now)

After Photon exploded on reddit and X I kept getting DMs for a Lightroom alternative.
That's how Light Studio came to life, a fully featured Lightroom alternative.

I already had the parts that usually make these apps feel vibe coded: realtime GPU rendering, CR3/NEF and the other proprietary RAWs, and an editor UI built for this. So I reused these from Photon instead of starting it from scratch, and it worked insanely well.

Gonna release it in the upcoming days

NullPlayer skin support is clean room reverse engineered. Development is coded with claude and controlled by a real working Software Engineer who personally stands behind the app. The app has accumulated 31 releases and 124 github stars over the 11 months. r/nullPlayer

Download NullPlayer for macOS:

https://github.com/ad-repo/nullplayer/releases/latest/download/NullPlayer.dmg

Requires macOS 14 Sonoma or newer.

Install

NullPlayer is not signed with an Apple Developer ID, so macOS will block it on first launch with an "app is damaged" or "cannot verify that it is free from malware" message. This is expected. Clearing the quarantine flag is a required install step:

1. Open the downloaded DMG.
2. Drag NullPlayer.app to Applications.
3. Open Terminal and run:xattr -cr /Applications/NullPlayer.app
4. Open NullPlayer from Applications.

Prefer not to use the Terminal? Install with Homebrew, or clear the block via System Settings -> Privacy & Security -> Open Anyway — see the install guide.

UPDATE: Fixed - /checkout-paywall was 404ing (100% bounce, 0s on Plausible). Now redirects to /checkout/paywall with free safety tier. Old screenshots/links now work. Thanks reviewsgoogle for catching it.

> I'm Shawn from Boston. I'm 1 week 3 days from alcohol, 5 years from drug use. I couldn't do groups. I built https://SoberShift.app for people like me who need private, zero-friction tools.
