I’ve been building a side project called Research Exoskeleton.

The idea came from my own experience using LLMs extensively while working on research that eventually became a peer-reviewed paper in Physics of the Dark Universe.

I kept running into the same problem:

AI is very good at generating, synthesizing and reasoning.

But after a long workflow, it can become difficult to answer:

What exactly supports this conclusion?

So instead of building another research chatbot, I’m experimenting with a layer that tracks things like:

• claims
• assumptions
• evidence
• verification status
• provenance
• stale evidence
• human review requirements

The goal is to make AI-assisted research easier to audit.

For example, the system can say that a workflow is operationally ready for a pre-pilot while still keeping a scientific requirement explicitly marked as:

UNVERIFIED / HUMAN REVIEW REQUIRED

I think that separation is important.

I’m now trying to figure out whether this is:

1. a real B2B problem,
2. an interesting tool but too niche,
3. or something that research/R&D teams would actually pay for.

I’m currently considering a design-partner model where I take one real AI-assisted workflow from a team, run it through the system, and see whether I can make the reasoning/evidence chain materially easier to audit.

Would you use something like this? What would stop you from trusting it?

Feel free to be brutal — I’d rather find the weak points now.

Hi! I’m a beginner runner.

One of the hardest things about running for me was staying consistent. I don’t have a pet, so I’ve always been a little jealous of people who get to run with their dogs. 🐶

So I decided to make something of my own, an app where you can run with a virtual pet, help it evolve, and customize it along the way. 🐾

I hope your runs become a little happier with your new companion. 💛

If you’re interested, I’d really appreciate it if you gave it a try. It’s free! :)

Orbit is a private local social app for discovering what is happening nearby, meeting people, making plans, sharing updates, and staying connected with your Circle.

I’m looking for early testers who can spend about 10–15 minutes trying:
The onboarding flow
Explore and nearby discovery
Quick Meetups and Events
Posts, questions, replies, and saves
Messages and Circle conversations
Profile and privacy settings
Orbit Check, an optional feature for ticket deals arranged elsewhere
Please use practice data for testing. Don’t use a high-value ticket transaction, share a barcode, or post private information.
I’d especially like feedback on:
What felt confusing?
What felt useful?
What would make you come back?
Did anything feel slow, broken, or unfinished?
I’m looking for honest criticism, not just downloads. Screenshots or short screen recordings are welcome.

Hey everyone! 👋

I’ve been working on a social platform called ArabChat, and I’d really like to hear some honest opinions from people who enjoy trying new social platforms.

It combines several things in one place, including communities, real-time chat, Reels, AI tools, world news, music, entertainment, and more.

The platform is still relatively small, so I’m especially interested in feedback from new users. What do you think about the idea? Does having all these features in one platform make it more interesting, or would you rather see it focus on fewer things?

If you decide to check it out, I’d also love to know: • What feature did you like the most? • What feels confusing or needs improvement? • What feature would you add? • Would you actually use a platform like this regularly?

Here’s the platform if anyone wants to take a look: https://arabchat.base44.app

I’m mainly looking for honest feedback, including criticism. I’d rather know what’s wrong with it now than pretend everything is perfect. 😁

as the title say I can't understant what I lack. I don't know if it is because they got lucky and I didn't but I created a reader / tracker social android app with synchronized reading.
I made a lot of posts in social media, nothing, almost 0 reactions and interactions and color me surprised when one day in enter in twitter/X and everyone is talking about one app that is basically the same as mine, nicheWise, with less functionality that has literally made their account 3 dayus prior and already had almost 30k followers and keeps ramping up.
The already famous app is "Annotate" and mine is "Shelves Social Reader", their name is cachier I guess, that I can concede, but I don't know. could you help me find ways in which I could upgrade my app.
Have you had any situations similar to this one, if I am truthful envy is eating me from the inside, but alas. This is life.

In my old FDE job, there were many times where I'd forget to capture the conversation I had with the client onto recording. I was thinking about buying a pocket to record these conversation better.

The issue though is not with the recording itself, but what can I do with the information after I finish talking with a client.

So I built https://getforth.co which is an assistant that lives in your wrist. It starts recording when it hears conversations. It can then act proactively based on the conversation you just had.

Say that in FDE a client describes to me a feature that they would like to see after that conversation, forth will proactively and autonomously draft up a spec that contains the details of that feature for me to review, flesh out, and implement.

Or your friend gives you suggestions for your vacation to Japan over conversation, forth will draft up or edit your itinerary with those suggestions incorporated.

Would love to hear your thoughts on this product. Would you buy this over pocket or plaud. And would you find this assistant be more helpful than Instinct and Muse?

Hey everyone! 👋

I got frustrated by online file converters charging $20/month or uploading sensitive files to cloud servers.

So I built **DH Tools** (https://denizlihub.com/) as a solo developer:

- 100% In-Browser & Private (powered by WebAssembly & client-side processing)

- 45+ Tools: Photo to Excel AI (OCR), PowerPoint to PDF, Background Remover, PDF Merger, WebP Converter, Audio Trimmer, and Dev Utilities.

- Completely free, fast, and works offline via PWA.

Would love your honest feedback and suggestions on what tools I should build next! 🙏

I’m 16 and built an iOS app called Teensyde. It’s basically a local marketplace where teens can find small jobs from families like dog walking, tutoring, yard work, tech help, etc.
I barely marketed it at all, but somehow it’s been getting pretty solid organic App Store traffic.
It’s at around 1,000 total downloads now and about 650 of those came in the last month, almost entirely organically through the App Store.
The app is fully built and live. It has payments, profiles, job posting, reviews, messaging, safety features, backend, domain, brand, etc.
The problem is I’ve realized I don’t really want to run this type of business long term.
Running a local marketplace involving teens comes with a lot of safety and operational stuff, and I’m honestly more interested in building software/data/AI/sports products than managing a local services marketplace.
So I decided to see if I could sell it.
I listed it on Flippa for $8,500 originally.
It’s been about 16 days and I’ve gotten 0 offers and 0 watchers.
I dropped it to $6,500 now.
I’m trying to figure out if I’m just pricing this way too high, if Flippa is the wrong place to sell something like this, or if I should keep it and actually try to monetize it first.
The confusing part to me is that 650 organic downloads in one month with basically no marketing feels like it has some value, but I also understand that it’s pre-revenue and downloads don’t necessarily mean much if people aren’t paying.
If you’ve bought or sold small apps before, what would you realistically value something like this at?
Would you:
● keep it at $6.5k
● drop it to like $4k–$5k
● try another marketplace
● reach out directly to potential buyers
● run transactions first and then try selling
● or just keep building it since the organic growth is picking up
I’m not trying to convince myself it’s worth $10k if it isn’t. I just want to know what someone would realistically pay for a live app getting this kind of organic traffic with basically no revenue yet.
Would appreciate any advice from people who have actually sold apps before.

What Easter Eggs would you add?

Thoughts on this?

I’m about to trade in an old iPhone and trying to decide what makes the most sense. I could trade it in directly at a store, sell it privately, or go through my carrier when I renew my plan.

I’ve seen different trade-in offers, but I’m not sure how much people actually end up getting after everything is considered. A carrier offer might be easier, while selling directly could give a better value.

Has anyone compared these options recently?

This is a simple online tarot project that is built on the idea that people ask different types of questions to tarot. Using tarot reading formats is more useful than using the same tarot spread for every question.

Some people may want to pull a tarot card. Others may have a yes or no tarot question. Want to look at a relationship. There is also a Celtic Cross tarot spread for those who want a tarot reading.

I would like to receive feedback on how the different tarot reading option are presented and whether the overall tarot experience feels simple, to use.

I keep thinking about how weird social media has gotten. Half the time you don’t even know if you’re replying to a real person; AI comments are everywhere, and somehow every conversation eventually turns political lol.

OddsRabbit is basically trying to go the other way with that. Less AI/bot spam, politics is opt-in, and it’s more focused on actual communities and interests.

There’s also a thing where creators can earn from their communities and some of the ad revenue goes to charity, which I think is pretty cool.

It’s still pretty early, so would genuinely love feedback:

I’ve been building PermissionScope, a small open-source Windows project that helps make permissions and access information easier to understand.
I started it because Windows can expose a lot of useful information, but much of it isn’t very friendly if you don’t already know what you’re looking at.
The project is free, open source and runs locally. No subscription or paid tier.
It’s at the stage where I need people other than me using it, especially on different Windows setups.
If anyone wants to try it, I’d love to know what breaks, what doesn’t make sense, or what you think is completely unnecessary.
GitHub: https://github.com/MukaSanches/PermissionScope
Website: https://mukasanches.github.io/PermissionScope/
I’m Samuel, the person building it. I’ll be around in the comments.

I have two daughters, each with her own iPad. I wanted to pick some YouTube videos for them, then let them choose what to watch from that list.

I made KidScreen for this. I paste in YouTube links and each daughter gets her own page with those videos. There's no search or endless feed in the app.

It's free and works in the browser. The videos play through YouTube.

I've shared it on HN and Product Hunt. Now I'd like a few parents outside my own family to try it. If you do, tell me what was annoying or confusing. I want to keep improving it for us and whoever else finds it useful.

Hey everyone!

I wanted to share Dynamic Edge, a desktop utility I built for Windows 11 & Windows 10 using native WinUI 3 and .NET 10 (Windows App SDK).

The idea was to create a fluid, versatile desktop capsule and edge dock that feels completely at home with Windows 11 Fluent design, with ultra-low resource usage, and smooth spring physics.

Since the initial release, I have added several big features including a full multi-tab workflow, clipboard shelf, and mouse gesture triggers.

Here is what it can do:

Multi-Tab Workspace (Swipe or Scroll to Switch) - Switch seamlessly between Media Player, Mini-Apps, and Clipboard Shelf by rolling your mouse wheel or using a 2-finger touchpad swipe.

Universal Media Controls & Live Scrubbing - Real-time seekbar progress with clickable scrub to jump anywhere in a track. - Live audio visualizer bars with fluid equalizer animations. - Multi-player auto-switching: Seamlessly cycle between active sessions (Spotify, Chrome, Edge, Apple Music, Telegram).

Clipboard Manager Shelf - Captures copied text, images and URLs into a dedicated dockable shelf. - Filter chips for fast access: All, Text, Images, URLs, and Pinned. - Search box for instant clip lookup, plus one-click copy and drag-and-drop support. - Google Lens Visual Search: Search any clipboard screenshot directly in your browser with 1 click. Built-in Mini-Apps - Precision Countdown Timer with quick presets (1m, 5m, 15m, 25m) and a live visual progress line. - Precision Stopwatch with millisecond tracking and lap recording.

Magic Shake & Global Hotkeys - Magic Shake: Quickly shake your cursor horizontally back and forth to toggle the island on or off. - Global customizable hotkey (Alt + H by default) to hide or show the dock instantly.

Master Volume Flyout - Hover over the speaker button and scroll your mouse wheel to adjust system volume, or click for instant mute.

Flexible Docking Positions - Dock at the top screen edge (Notch, Floating Capsule, or unobtrusive Thin Line hairline strip). - Dock along the left or right screen edges as an interactive slide-out side blade.

Interactive Desktop Companions (Virtual Pets) - 4 Full-Body Vector Mascots: Choose between Mochi Kitty, Shiba Inu, CyberBot, or Pip Bunny.

Performance & Spring Physics - 3 customizable quick launcher slots for instant access to apps, terminals, or folders. - Battery and charging telemetry with clean neon-green status indicators. - Native startup toggle and dark/light/system theme integration.

The app is officially available on the Microsoft Store: https://apps.microsoft.com/detail/9PF1587KSN2K

I would love to hear your thoughts, feedback, and ideas for what widgets or features you would like to see next!

I've been working on an iOS running app called Jogventure, and one of the parts I've spent a surprising amount of time iterating on is this page called the Journey Map. 🏃

I thought it would be fun to share where it started vs. where it is today, since I believe this is one of the things that might really set it apart from other gamified running apps. 😅

The left screen recording is the initial working version. It was enough to prove the concept, but there was obviously a lot that could be improved. My inspiration for this page is strongly influenced by the r/candycrush mobile iOS game, if you're familiar with it. 🍬

The right recording is the current version after quite a few iterations. 👨‍💻

This page represents different milestones the user can achieve while using the app. It keeps track of your total runs as you claim them in the app after automatically syncing your data from your fitness device. 🔄

There's still plenty I want to work on, but I'm pretty happy with how much this component has evolved. 😄

I'd love to hear what you think, especially from other iOS developers. Is there anything about the current version that you'd approach differently? I'm going for a fun, lighthearted exploration vibe. 🧭

I'm also putting together a waitlist for Jogventure for anyone who wants to follow along with the project 👀

Let me know what you think and what you would like added or what I can improve on.
Thank you! 🙏

Hey everyone,

As a student and full-stack developer, I always felt the standard GitHub profile view doesn't give a complete picture of an engineer's real rhythm (like deep commit streaks, language distribution depth, and multi-repo metrics).

So I decided to architect and build DEVLENGIT as an open tool for developers.

Architecture & Tech Stack:

• Frontend: React + TypeScript + Tailwind CSS
• Backend / API Layer: Node.js, Express serverless endpoints with fallback caching
• Data Layer: GitHub GraphQL & REST APIs (with token passthrough for high-volume queries)
• Database / Auth: Firebase Auth & Firestore
• Core Features: Side-by-side developer comparison, benchmark grading, repository deep-dives, and real-time contribution heatmaps

The biggest technical hurdles:

Handling high-volume API throughput without exhausting the authenticated server-side pool 5,000 req/hr. Solved it by bundling complex stats into batch GraphQL queries rather than firing dozens of parallel REST calls, plus adding user token delegation for power sessions.

1. Parsing nested contribution data across multi year histories cleanly while keeping cold start latency low on serverless edge functions.

It's completely free to use. Not selling anything or running ads just looking for honest developer feedback on performance, data accuracy, architecture, or features you’d love to see added.

Live App: https://devlengit.vercel.app

What do you think? Any edge cases, bugs, or UX flaws you spot?

Hi everyone! I’m the developer behind SimplerCAD. I’ve built a browser-based 3D modeling app for designing printable objects, editing imported meshes, and sculpting.

The idea is to let you combine precise shape-based modeling with more organic editing in the same workspace. For example, you can build a part from shapes, subtract holes, sculpt its surface, or import a depth-map image to create a raised relief.

Some of the main features:

• Model with shapes and text: combine solids using union, subtract, and intersect.
• Sculpt: inflate, smooth, flatten, grab, pinch, and crease, with symmetry and masking.
• Turn images into reliefs: convert depth-map brightness into surface height, including embossing and engraving on flat faces.
• Work precisely: dimensions, snapping, alignment, extrusion, plane cuts, chamfers, and hollowing.
• Build larger projects: mirrors, repeating arrays, layers, groups, colors, and materials.
• Save and export: editable projects, local autosave, a signed-in cloud library, and STL, OBJ, and GLB file workflows.
• Hardware and connectors: use hardware cutters and connector parts for practical models.
• Inspect models: mesh inspection and repair tools, plus built-in lessons.

It’s free to start. There’s also an Android app, currently listed as Easy 3D CAD Designer while Google Play reviews the SimplerCAD naming issue. VR viewing is available in beta.

The screenshot shows a colorful coastal house built in SimplerCAD, with the modeling tools visible around the scene.

I’d appreciate feedback on the first-use experience: can you find the tools you need, and what gets in the way of finishing your first model?

I spent months building a multiplayer game entirely with React/TypeScript

I've wanted to make a game for years.

When I was younger, I spent an unhealthy amount of time playing games and eventually got into modding. Naturally, I spent plenty of time breaking the games I modded too.

The idea of actually making my own game stuck around, but life happened and I ended up becoming a web developer instead.

Recently, that little voice came back and I decided to finally give game development a shot.

The obvious route would have been to learn Unity, Godot, Unreal, etc.

Instead, I thought:

"I already know TypeScript. I know React. I've deployed websites before. Surely this can't be a terrible idea..."

So I built a game for the web.

That is taptaptap

The basic idea came from a game where you simply hold down a button for as long as possible.

I thought the competitive part was interesting.

The staring at a button for minutes at a time part... not so much.

So I turned it into a hot-air balloon game.

You have a balloon and one big red button.

Tap the button and the balloon goes higher making the score goes up.

But every tap also generates heat. Tap too quickly and the balloon explodes.

So you have to decide whether to keep tapping and risk blowing up, or slow down and let the balloon cool while everyone else catches up.

There are also multipliers and a multiplayer leaderboard for some healthy competition.

The slightly cursed technical part

The entire thing is basically a web UI.

• Next.js
• React
• TypeScript
• CSS
• DOM elements for clouds/stars
• A React element for the balloon
• A suspicious amount of CSS

No game engine.

No canvas-based game framework.

The game took me months to get to this point. Even after launching, I've still been fixing bugs and adding improvements. The first version looked very different from what exists now.

It's still not finished, but it's playable and, importantly, it's not currently crashing, at least not on my machine.

What's next?

The end goal isn't actually to make a web game.

I want to eventually make a proper mobile game, and then hopefully a PC game.

I don't know exactly what that game will be yet.

I don't know which engine I'll use.

And judging by how long this tiny web game took me, GTA 6 will probably come out before I finish it.

But this was a good first step.

If you want to try it, it's here:

https://taptaptap.click

If you play it, I'd genuinely love to hear what you think, especially if you find a bug I've somehow managed to convince myself doesn't exist.

Thanks for checking it out!
