Hi everyone,

I'm a 19-year-old engineering student and over the last year I've been building Revast.

Most AI study tools focus on generating notes, flashcards, or summaries.

After talking to students, I realized the bigger problem was that students often don't know:

• Which topics they're weak at
• Whether they're improving
• If they're actually ready for an exam

So I rebuilt Revast into a learning workspace.

Students upload their course material and get:

• Topic-by-topic notes

• Flashcards

• Practice quizzes

• Mock exams

• An AI tutor

• Progress tracking across the entire course

The goal is to help students learn, test themselves, and track mastery in one place rather than jumping between multiple apps.

I'd love feedback on the product, onboarding, or overall concept.

I just built the most interesting project I’ve worked on so far.

Instead of writing long AI prompts, you simply paste your brand’s website.

The app automatically analyzes your brand, colors, and overall style, then generates a motion design video that matches your identity.

No prompts. No editing. Just your website.

I’d love to hear your feedback.

Velrix is a tool that helps website owners identify where visitors may be hesitating, getting confused, or dropping off.

Over the last week I've made a lot of changes based on user behaviour, including:

• Simplifying the homepage
• Reducing onboarding friction
• Improving the mobile experience
• Showing value before requiring signup
• Making the audit process clearer

I'm now at the point where I've looked at it so many times that I'm probably blind to the obvious problems.

I'd love honest feedback on:

• First impressions
• Clarity of the value proposition
• Whether you'd actually try the audit
• Anything confusing or frustrating
• Mobile experience (especially)

Don't hold back — brutal feedback is welcome.

I’ve been working on this on & off for a while and finally decided it was in a good enough state to show people.

I consume a lot of media and keep way too many lists of things I like. At some point I realized every recommendation service stays in its own lane – books recommend books, music recommends music, games recommend games – but I wanted something that could connect all of it.

Interestnaut is my attempt at that. Rate a few books, movies, TV shows, games, or songs, and it builds a taste profile, assigns you an archetype, and recommends things across every type of media. It’s somewhere between a recommender and a tongue-in-cheek horoscope. Also doubles as a place to create cross-platform lists and search/discover media by shared themes.

Website: https://interestnaut.com

I’d really appreciate feedback -- especially whether the archetype feels fun/reasonable, whether the recommendations make sense, and whether the overall idea is interesting enough to try out. It's free, and no login needed (data is stored on whatever device/client that's used) unless you wanted to move a list from one device to another.

(Also happy to answer questions about the implementation if anyone’s curious.)

I had a hard time remembering when/how to watch all the games I care about so I made an app that aggregates many different sports and allows me to create a custom feed of all the stuff I care about.

TV/Streaming info in the future (scroll down) and highlights in the past (scroll up). It's a simple idea but it works great for me. I'd love any feedback you might have. Thank you so much.

Builders-welcome post with the substance up front (disclosure: I'm the maintainer). OmniRoute is a free, MIT, self-hosted AI gateway — one OpenAI-compatible endpoint over 237 providers — built around two problems: runs dying on a provider 429, and tokens bleeding on tool/log output.

One endpoint, 237 providers — 90+ of them free. You point any tool or agent at a single OpenAI-compatible endpoint (localhost:20128/v1) and it can reach 237 LLM providers without you rewriting anything. 90+ have free tiers and 11 are free forever (no card), which aggregates to ~1.6B documented free tokens/month — and that's honest, pool-deduped math (we count each shared pool once instead of inflating it; the methodology is public in the repo). There's a one-command setup-* for 13+ coding tools (Claude Code, Codex, Cursor, Cline, Roo, Kilo, Gemini CLI…), so switching your existing setup over takes seconds.

Fallback combos — so it never stops mid-task. A "combo" is a ladder of models the router walks automatically: your subscription first, then API keys, then cheap models, then free ones. When a provider returns a 500 or you hit a rate limit, it slides to the next target in milliseconds, mid-request, and your tool never even sees the error. There are 17 routing strategies (priority, weighted, round-robin, cost-optimized, auto/coding:fast…) plus three resilience layers — a per-provider circuit breaker, a per-key cooldown, and a per-model lockout — so one dead key can't take down a whole provider.

Fusion — an ensemble mode for the hard steps. Beyond simple routing, there's a fusion strategy that fans a single prompt out to a panel of different models in parallel and then has a judge model synthesize one best answer (mixture-of-agents, built in). It's cost-aware, so easy turns stay on one fast model and it only fuses when the step is worth it.

A 10-engine compression pipeline — the part most routers don't have. Every request flows through a transparent compression pass you can toggle/stack per combo. Instead of one trick, it stacks the best of the open-source ecosystem: RTK filters command/tool output (git diffs, test logs, builds) at 60–90%, Microsoft's LLMLingua-2 does ML semantic pruning, Caveman handles prose, session-dedup strips repeats across turns. Critically, code, URLs and JSON are preserved byte-perfect, and a default-on inflation guard throws the compressed version away and sends the original if compressing would actually grow the prompt — it never makes things worse. On tool-heavy sessions that's ~89% average input-token reduction (an 8k-token git diff becomes a few hundred). Full credit to every upstream project (RTK, Caveman, LLMLingua-2, Troglodita) is in the README.

Agent-native — the agent can drive the router itself. There's a built-in MCP server (95 tools across 30 audited scopes, over stdio / SSE / streamable-HTTP), plus A2A (v0.3, JSON-RPC 2.0) support. That means an agent can query providers, switch combos, read its own remaining quota and manage memory through the gateway — not just consume tokens through it.

It's 100% local (zero telemetry, AES-256-GCM at rest), MIT-licensed, has a prompt-injection guard on every LLM route, opt-in memory, and runs on npm, Docker, desktop or your phone via Termux.

For context on whether it's worth your time: it's grown to ~9.8K GitHub stars, 1,490+ forks and 280+ contributors in ~4.5 months, with 21,000+ automated tests and 1,830+ issues closed — so it's a battle-tested project, not a brand-new experiment.

Would value a critique of the routing/compression architecture from this crowd.

I’m building NoUploadTools as a simple directory of web tools that respect users’ privacy.

The goal is to list tools that are:

- Open source
- Zero login
- Work offline / client-side where possible
- Free forever
- No ads
- No file uploads to a server

Site: https://nouploadtools.com

If you’ve built a tool that follows these principles, feel free to submit it.

Would also love feedback from the webdev community on what else should be required before a tool is listed.

Edit: NoUploadTools is now open source.

I am building a screen recording alternative to Loom called Arroup.com

It's a in browser screen recorder with Facecam aswell, where you record your educational content, course or tutorial for your collegue or team members in a company or anyone really. You can trim the beginning and the end of the video and share folders and single videos with anyone as a sharable link.

Should I keep in doing it?

I run a book tracking app called Book Assembly and have just added public profiles and sharing. Looking for readers who'd be up for trying it out and letting me know what works and what doesn't.

What it does:

Track your library, log reading progress, set yearly goals, and get detailed stats about your reading habits. It imports from Goodreads, StoryGraph, and LibraryThing if you want to bring an existing collection across.

The new bit (and the bit that needs testing):

Public profiles are now live. You get a shareable page at bookassembly.co.uk/@yourname showing your currently reading (with progress), favourites, recently finished books, reviews, and reading goal progress. Your library is private by default and you choose what's visible, book by book.

Book pages also show community stats now: how many readers have a particular book and its average rating, all anonymised. The more people using it, the more useful these get.

Other bits that might appeal to this community:

• Reading goals for books, pages, and listening time
• Cover to Cover: a Spotify Wrapped-style year in review with shareable cards
• Reading timer with session tracking
• Moods, pace, and content warnings on each book
• Stats page with charts for genres, moods, reading patterns, and more
• Proper audiobook support (listening time counts towards goals and streaks)

What I'm after:

People who'd have a poke around the social features in particular. Set up a profile, make a few books or lists public, see how it feels. If something's confusing, broken, or missing, I want to know. There's a feedback form in the app and I'm in the comments here too.

It's completely free. No premium tier, no ads, no paywall.

I recently built a tool to streamline the getting your art print ready process. I know there are multiple out there already, but none seemed to tick  the boxes for my needs.

My initial thoughts were to keep it as streamlined as possible, but now I feel I can add some extra features without making it too cluttered as efficiency was always top of mind.

Here it is: www.upratio.art

I’d love some feedback, so if anyone was open to testing it out and providing some, I’ll give you unlimited free access in return.

Much love

Hi everyone,
I’ve spent the last year building a Chrome extension called Paneo because I was tired of opening Chrome and having bookmarks, downloads, shortcuts and tabs scattered everywhere.

Instead of another empty new tab, I wanted a workspace where everything I use daily is in one place.

Current features include:
📁 Vault for bookmarks, files and folders
⚡ Quick access to your favorite websites
🗂 Recently closed tabs
🎨 Customizable themes
🚀 Clean productivity dashboard
💻 Designed for people who spend a lot of time in Chrome

I’m still in the early stages (currently only a handful of users), so I’m much more interested in honest criticism than compliments.

What I’m trying to figure out is:
What’s the first thing you would improve?

Is there any feature that would make this part of your daily workflow?
What would stop you from using it?

Chrome Web Store:
Paneo on the Chrome Web Store⁠
I’d genuinely appreciate any feedback good or bad. I’m actively improving it based on what people actually need.
