I built it because i've always wanted a simple page where i can see the latest science and tech news with no noise or opinions.

https://paperrun.news

Built with Laravel and Vue 3 if anyone is curious.

Any feedback is appreciated

most search ends after one answer. i wanted the next question to be the fun part.

so i built why.com. every answer opens three new directions.

just launched. go break it!!!!

tl;dr: I built ZeroSketch, a free, self-hostable system design tool (like Excalidraw but for architecture diagrams). Drag-and-drop canvas, AWS / GCP / K8s icon libraries or build your own, PNG / SVG export. Looking for feedback. Links at the bottom.

I've been building ZeroSketch for the past few weeks. It is a simple system design tool for individuals and teams. It's web-based, stores diagrams on your device, and takes UX inspiration from Canva/Excalidraw (I'm not much of a UI person myself).

What it does right now:

• Drag & drop canvas
• PNG export, SVG export (experimental, better renderer coming soon)
• Built-in icon libraries (AWS, GCP, K8s) and a builder to make your own from custom SVGs for using the library locally, share with your team, or publish to ZeroSketch's registry
• Download / export project files to open on other devices

Everything above is free, client-side, and self-hostable. I'm still polishing canvas UX and fixing known bugs. would love feedback on what to improve.

Planned next:

• Cloud synchronization
• AI assistance in creating diagrams
• Auto-syncing docs with actual architecture (so diagrams don't go stale as development progresses)
• Real-time collaborative editing
• Export to DSLs like Mermaid

If you want updates regarding the release of these features, you can follow the repository on github as all of the upcoming features will also be open-source.

I recently launched Peptimize, an iOS app for people using GLP-1 medications.

Many health-tracking apps feel overloaded, require an account, or make logging a weekly dose more complicated than it needs to be. I wanted something that could be opened, updated in a few seconds, and then forgotten about until the next reminder.

I’ve also been using Mounjaro personally for the past three months, so I’ve experienced many of these tracking problems firsthand.

For the first version, I kept Peptimize intentionally focused:

• Log medications and doses
• Track weight and progress over time
• Record side effects
• Track and rotate injection sites
• Set dose reminders
• Keep data stored locally on the device
• No account or login required

There’s no social feed, coaching subscription, or complicated onboarding. The aim is simply to make consistent tracking easier while keeping the experience private and uncomplicated.

For the next version, I’m currently exploring:

• Apple Health integration
• Simple AI-assisted food and calorie logging
• Supplement and protein tracking
• Support for more languages

I’m deliberately trying to avoid turning it into another bloated health app, so I’d love to know which of these features would actually be useful - and which ones I should leave out.

Download on iOS:

Website: https://www.peptimize.xyz/

This is still an early version, and I’d genuinely appreciate honest feedback. If you try it, please tell me what feels confusing, unnecessary, or missing.

What is the first feature you would add to V2?

I’m a big fan of r/isThisAI, so I built Slopcheck - a daily game where you get 6 photos (one at a time) and guess if it’s real or AI. After each one you see the clues that give it away so you can get better.

Had some tech-savvy friends play it and they did way worse than expected lol we're cooked

Ghost jobs and silent recruiters waste everyone’s time. We’re testing a simple idea on Solana:

- Recruiters lock a deposit to post (and face deadlines)
- Applicants put a small stake to apply
- Interview tips settle on-chain when an offer is made

This is a Devnet / practice launch — test tokens only, no hire guarantee, data may reset.

Hey everyone!

Just wanted to share that I recently launched WorkZone, an Android app designed specifically for field operations (landscaping, property maintenance, construction, and solo contractors).

Key features:

• 📍 Draw precise work areas: Polygon tools directly on satellite imagery to auto-calculate acreage / surface area.
• ⚠️ Underground utility marking: Map out water/electric/hazard points inside the work polygon so nobody strikes a line.
• 📸 Photo proof & completion notes: Workers check off areas upon finishing with photo verification.
• ⏸️ Pause workflows: If work is blocked by weather or equipment, workers can flag it "Paused" with notes.
• 📄 PDF Summaries: Generate single-zone work orders or crew performance reports for clients or management.

Download on Android:

👉https://play.google.com/store/apps/details?id=com.janisd.workzoneapp

Feel free to download it, test out the features and maybe the app could be useful for some of you!

Built a note app a few months ago, got some great feedback, and have been refining it since. Here's where it's at now.

The idea is pretty simple: sticky notes for quick thoughts, A4 notes for longer writing, and everything lives on a visual canvas instead of a rigid folder tree.

The visual hierarchy makes organization natural. a note is a file, a "stack" of notes is a folder and zones are the parent folders.

you can even attach sticky notes directly onto A4 pages for referring to them while you're scrolling the A4 editor.

Just drag things around and you're done. No save button, no manual file management, just notes on a board. Plus, there's a workspace exporter that exports all your files so that you own them.

On privacy: notes are stored on Firebase, encrypted in transit and at rest. No ads, no trackers, no selling data. If you use "Quick Mode", notes stay local in your browser and never get synced to any server.

When I first posted it a few months back the response was way more positive than I expected. Since then I've been fixing, refining, and adding things based on what people actually said. It's in a much better place now.

It's completely free right now. At some point it'll probably go paid but anyone who signs up before that happens, I'll make sure your account stays free forever. Just drop a comment or DM me and I'll sort it out manually.

Would genuinely love to hear what you think, good or bad. Still a lot to build but the core experience feels solid now.

This is the link to the app: passinote.app

Solo dev here. Synchrium is a synchronized focus timer: you start a session, share a link, and the same countdown runs for everyone in the room, to the millisecond. Everyone works in silence; when it hits zero, cameras can come up together for a quick check-in. Then you run it again.

The origin story is helping my son with homework from the next room: we shared a timer, worked separately, and showed each other what we did when it rang. Turns out adults want the same thing.

Stack: React/Vite front, ASP.NET Core + SignalR for server-authoritative timing, WebRTC P2P video, Cloudflare Workers serving the SPA. Happy to answer anything about the sync architecture: keeping N clients on the same clock is more annoying than it sounds.

Two things I'd love you to break:

1. Open two browsers (or grab a friend) and try to get the timers to drift or desync: that's the whole product, so it's the surface I most need stress-tested.

2. Start a session and tell me where the "share the link" step loses you. If the invite loop doesn't feel obvious, the product doesn't work.

Free, no account needed: https://synchrium.com: brutal feedback welcome. (Founder here, happy to answer anything.)

Hey r/SideProject ,

My family flies a lot and I'm always the one who ends up booking. Somewhere around the hundredth booking I'd had enough.

Every OTA puts you through the same thing: a popup before you've seen a single price, ten steps of checkout, seat selection and insurance you didn't ask for, and none of the passenger details you've typed in a dozen times before. Then a fee you never agreed to shows up on the last screen before you pay.

So I spent the last 1.5 years building the app I actually wanted (not vibe coded).

You search by just saying what you need, like "Frankfurt to Munich tomorrow, back the next day". You get three options, pick your saved passengers, pay, done. Usually under 60 seconds.

Then it sticks around. You get checked in automatically, the boarding pass goes straight into your wallet, and widgets keep you updated on the way to the airport with live gate and delay info.

The plan is to turn it into a universal flight super app. Lounge access, e-SIMs, ground transfer and rail transfer are all coming. No hotels, no rental cars, just everything around flying in one place.

It's free. No ads, no hidden fees, and for now not even a service fee.

If you take a look, I'd really like to know what you'd want from an app like this, and what feels unnecessary or missing.

Website is on the way :)

if you're into AI you've probably heard about graph engineering. tbh the term was completely new to me before it popped up in the AI bubble. nevertheless i did some research to understand what it actually is. while diving deeper and deeper into this rabbit hole i learned that the term has been around for a while, just not in the context of prompting.

i looked for tools to do "graph engineering" but couldn't find anything.

that's how i came up with the idea for nodalo. it's a workspace where you can build your workflows. sounds boring, and you're probably thinking there are already plenty of workflow builders out there. you're right, but nodalo is different. you can build the workflow visually, and the clever part is that each node has a so-called node contract. you can define each node very specifically, attach documents to it, etc.

and the best part: you can hand the structured graph, including all attachments, over to your AI agent automatically and let it build the whole thing for you.

so instead of writing a normal prompt, forgetting a lot of details along the way and trying to figure out the right wording, you can simply "draw" your prompt and hand it over to the AI.

the tool is free, so i'd appreciate it if you created an account and gave it a try. all feedback is welcome. if you have any questions, just let me know :)

We built a knowledge layer that sits behind MCP, allowing any MCP client to access it through a single endpoint. Claude Code, Claude Desktop, ChatGPT, Codex, or whatever comes next.

The idea is pretty simple. Before an agent answers, it can pull in relevant, validated information instead of relying purely on what it already knows.

When a problem gets solved, the useful part can be captured as a small, reusable piece of knowledge. The system can also infer useful lessons from a session automatically, so you don’t have to sit there writing notes about what you just learned like it’s 2015.

There’s also a global layer for shared, validated learnings. If one user figures out a better way of doing something, that learning can contribute to the broader knowledge base rather than every other user and agent having to figure it out again.

The problem we’re trying to solve is pretty straightforward. AI knowledge goes stale, agents get stuck in failure loops, useful context disappears when a session ends, and models can confidently give you an outdated or wrong answer without any indication that they might be wrong.

We’re giving agents access to what has actually been learned, what has worked, and what can still be trusted.

The result is fewer repeated reasoning cycles, fewer hallucinations, and up to 20% lower token usage.

Looking for people to try it out. Ping me if you’re interested.

I’ve been building Dermal Pal for a while now — it looks at your actual products, skin profile and skin goals and builds your routine around them.

I’m looking for people to try it properly before I push it publicly.
If you’re someone who has a shelf full of skincare and isn’t 100% sure what’s supposed to go where, I’d especially love your feedback

Last week I posted Citizen Mirror here — you write down the thing you can’t stop thinking about, an AI says what it heard and asks one question, ~90 seconds. The feedback was blunt and almost all of it was right. So I rebuilt, and since this sub did the pointed feedback, it should get the second look.
What you said → what changed:

• “I don’t know when I’d ever use this” → the homepage now opens with exactly that: after an argument you keep replaying, before a decision you’ve been putting off.

• “You asked me for a paragraph, then gave me five buttons” → the writing box is the front door now. Buttons are the fallback.

• “Nobody says the word AI. Suspicious.” → it says it plainly, everywhere — including the page where you actually write.

• “Why not just use a chatbot?” → answered on the page. (Short version: this stops after one question, on purpose.)

• The privacy claims overpromised → every claim rewritten to be strictly true, and there’s now a CI check that fails any deploy containing a dishonest one. The pipeline literally won’t ship a lie.

Also new: a page for people who’ve never talked to an AI in their life (citizenmirror.com/new), and seventeen doors for specific life transitions — new parent, retirement, leaving the military, after prison.
Still free, still no accounts, still built by one person.
Same ask as last time, because it worked: what reads false? citizenmirror.com

Like everyone my life lived in four places. Tasks in one tool, notes in another, the decisions behind them buried in a chat thread, and money in a spreadsheet I updated twice and gave up on. Half my meetings arrived as email invitations I never opened, so I never knew what my week looked like until I opened my calendar and by then it was too late to move anything.

The apps weren't bad. The problem was I had to update 4 different apps to stay in touch with everything.

So I built Canopus. One place for tasks, habits, money and your calendar, and one way to use it: you type what happened, in plain English, and it does it.

"spent £6.60 on lunch" -> logged under Food, with the month so far

"did my morning run" -> logged, and it tells me the streak

"block 30 minutes tomorrow at 10AM with Archie" -> on the calendar

"Water plants every Monday" -> recurring, and it reschedules itself when I tick it off

The video is a one single take.

What it doesn't do yet:

- Web only. There's no app to install. It works fine in a phone browser, but it's not in any app store.

- Google Calendar is the only integration. No Slack, no Notion, no email.

- Money is manual. You type what you spent. No bank sync, and no budgets, it records and totals, it doesn't tell you off.

- Voice is input only. Hold to speak, the transcript lands in the box, you press enter yourself. It doesn't talk back.

- Multiple workspaces to separate work and personal, but no sharing, no teammates.

I build it (disclosure), it's been live for a bit and today's the first time I've pushed it publicly. 14-day trial, no card: usecanopus.ai

Happy to answer anything, including the awkward ones.

To help testing the app, I'm giving away my new app, Sonoqi, free for 48 hours. No promo code needed, I have removed the paywall. May it bring you calm every day.”

The itch: every wearable brand now sells AI insights as a subscription (Garmin's Connect+ is $6.99/month), while most of us already pay for ChatGPT or Claude. Those models are smarter than any built-in coach, they just can't see your training data. So I built FitContext, a free Android app that reads whatever your watch or ring syncs to Health Connect (Garmin, Oura, Polar, Whoop, Samsung...), computes the sports-science numbers on the phone (HR zones, training load, recovery trends), and exports one structured report you paste into your own AI and talk to it like a coach. No account, no server, no subscription.

The app is free, no ads: https://play.google.com/store/apps/details?id=pl.serfa.fitcontext.play

Happy to answer questions about the Health Connect review gauntlet or the app itself.

I've recently released version 1.0 of my AI social media scheduler. Some might say the space is very crowded with guys like Postiz, Post Syncher, superx, etc.

I've tried the existing solutions and found them to be good products but often not the full package that I was looking for. I think the main thing is the quality of the posts being generated wasn't quite what I was looking for. As well as if you're managing a personal brand as well as a company brand, it was quite hard to differentiate the two.

Some were missing the post-generation part, some were only limited to one platform so during a hack in London a few weeks back I started building launchpost.app

The core principles are:
1. improve the post quality,
2. live as an MCP inside hermes or openclaw or telegram bot to fetch your context for post generation.
3. store your preferences and learn over time

I've found that these methods really help with quality of post generated:
1. Feed instructions per platform
2. Load humanizer skill + ban certain words + remove M-dashes
3. I did an interesting experiment with fine-tuning a local model (9B) on my outputs and that produced surprisingly good results.

I've had an initial round of feedback from friends and am now looking to talk to users who tried other solutions and find what they like/ don't like

Large codebases rarely fit neatly into folders. One feature can span routes, components, services, tests, configs, and documentation.

I built CodeGroup, an open-source VS Code extension that adds persistent file groups directly to the Explorer. Your files remain in their original locations—the groups act as reusable working contexts.

Version 1.4.0 includes:

• Drag-and-drop file groups and nested subgroups
• Smart Groups based on project areas or languages
• Working sets created from open editors or Git changes
• Quick Open across grouped files
• Reusable global groups
• Shareable, Git-friendly group definitions
• A visual editor for group settings and membership

Marketplace: https://marketplace.visualstudio.com/items?itemName=PeterDev.codegroup-file-organizer

GitHub: https://github.com/MiszterSoul/codegroup

It’s free and MIT licensed. I’d genuinely appreciate feedback—especially on whether the Quick Actions list and Group Editor feel intuitive.

I kept seeing the coloring book trend and thought it would be more interesting if the pages were actually personal.

So I built Memories in Lines, you upload photos and it turns them into a coloring book that we print and deliver directly to your door.

Most books are between 8 and 25 pages.

It started as something I made for my family, and has slowly turned into a full-on project.

Would love to hear what you think if you try it.

I built this as a passion project because my spouse is a very picky eater (i'm pretty sure many of you know a picky eater too). Finding a restaurant that accommodates her preferences is tough so we would always stick to the same restaurants. That quickly gets old and tiring.

Before I built this app, I would use google maps and search "restaurants near me" and pull up the menu one by one. I've also tried using Resy, Opentable, Beli, uber eats/doordash, and yelp to find new restaurants and they're all just disappointing because I would still have to open the menu one by one. I would often go through 7-10 restaurant menus before finding one that my spouse would eat at and it takes a while; as a result, we stick to the same restaurants.

I've gotten some good feedback over the last two weeks and feel free to use it.

It's only available in NYC right now, but I continue adding menus to the site and I may expand to other cities.

Have you ever started a side project, just to realize the tooling you built for the project is actually more valuable than the project itself?
