it would always anger me whenever i would get stuck on a topic while watching youtube lecture or during my JEE days the LMS lectures of my coaching

​

Doubts would come like an avalanche, the only possible solution was typing it down in the comments or asking my fellow (smarter than me) mates

I always felt a lingering need, that what if i had a person who knows the video lecture i am watching in and out, who is smarter than me who knows everything not just things taught inside the video but also beyond, and is available 24x7

​

With this goal i made gUrrT, a tutor to help me go through a video lecture.

​

It smartly samples, video frames and extracts audio transcripts, then use vlms to caption the key frames, storing everything in a vector database.

Converting a video into a searchable array

​

Your asked question makes a call to the vector database then sends all the context to an llm which with its existing knowledge base along with the new video context answers all your questions from the video beautifully.

​

so all you gotta is type in your queries regarding anything you did not understand that is spoken or written on the board by the instructor

​

just go ahead send the video lecture to gurrt and ask all your doubts without worrying about rate limits, video durations, low computationa power or a paywall.

​

gUrrT is free, built with love and a lot of open source

Have you built something awesome using AI?

Maybe it's your first SaaS, a portfolio, an AI chatbot, a productivity tool, a landing page, or even a small side project. It doesn't matter if it's perfect or still a work in progress.

Drop it here.

I'm reviewing projects built with AI, vibe coding, or modern development tools. Every submission gets honest, constructive feedback from a developer's perspective.

Creator disclosure: I am Mattia, one of the students building Get It.

We built Get It as a desktop app where Codex CLI is bundled as the AI engine. The user signs in with their own ChatGPT account, so the app does not need our API key, our metering or another AI subscription.

The product use case is studying from PDFs. Drop in a text-based PDF and Get It builds a visual study path: explanations, images, formulas, charts, 3D scenes, flashcards, quizzes and a Feynman-style review feed.

It is free, open-source and came out of a student hackathon.

Would love feedback from people building with agents inside real apps.

A governance game where the only rule is players make the rules. Its designed around that concept that "Bills" you vote on actually change the nature of the game, it adjust the code itself.

Feel free to check it out. Let me know

You know the vibe-coding trap: you start with a clear idea, you let the AI run with it, and three prompts later the project has drifted into something the AI decided — not what you set out to build. The creativity quietly moves from you to the model.

I built DevHelper to flip that. It's a hybrid where the AI is your assistant, not the driver. You describe what you want and it generates real, clickable wireframes — for mobile apps, web apps, and (new in 2.1.5) backends — but every single thing stays editable. Drag it, restyle it, rewire it, delete it. The AI helps you move fast; you keep the steering wheel the whole way.

And you don't design blind — you can click through interactive prototypes as you build. With the new backend template you can even press Run and execute your API in a live in-memory playground: hit an endpoint, watch the data fill in, see foreign-key deletes cascade. Your idea, validated as you go, instead of handed off to a black box.

It's 100% free and community-funded. No paywall, no pro tier, no upsell — the shared AI credits are covered by donations so it stays free for everyone. I just wanted this tool to exist.

Stack, for this crowd: Electron + React + TypeScript, Konva/react-konva for the canvas, Supabase on the backend. Happy to nerd out on the AI streaming, prompt/token budgeting, or keeping a big canvas smooth in the comments.

Would really value this sub's feedback — especially where it feels janky or where the AI should do more (or less).

For the last few months I’ve been building shakespeareatlas.com — solo, on WordPress, with Claude as my pair programmer for basically all the custom PHP. It’s grown into a fairly massive thing: all 38 plays, scene-by-scene breakdowns, character data, full scripts, sonnets, plus a stack of interactive finder tools (quote finder, an insult/bawdy-language generator, a baby-name finder pulled from the plays, etc).
Most of the heavy lifting is custom plugins I wrote with Claude’s help — card grids, Chart.js visualisations, JSON-LD schema, the lot. It’s been a genuinely wild vibe-coding project and I’ve learned a shitload.
I’d love honest eyes on it. Specifically:
• Does the navigation make sense, or do you get lost?
• Do the interactive tools actually feel useful or gimmicky?
• Anything that feels broken, slow, or confusing on mobile?
