Paste any YouTube URL and ask questions like "what are the key points?" or "what did they say about X?"
Built this because I was tired of scrubbing through hour-long talks/podcasts to find specific information.
Tech stack (I'm a novice so please go light on me lol)
Frontend: HTML, CSS, JS (no frameworks)
Backend: Python with Flask
PostgreSQL for user data and request tracking
Auth0 for authentication
Stripe for subscriptions
Rate limiting using Redis
SmartProxy for YouTube access
Deployed on Render.com
Google AI Studio for LLM integration
It's request limited to 3 requests given the AI integration.
Any feedback would be super appreciated! I hope this is helpful!
- pavel_lishin 2y agoHow much does it hallucinate?
- GentleNapkin 2y agoShould be very little since it uses the actual youtube transcript. I havent noticed any obvious hallucinations. I do use a cheaper large language model (Gemini 1.5 Flash) due to cost constraints, so theoretically I could get better answers using a more expensive large language model (eg Gemini 1.5 Pro). However, because the answers are limited to the transcript it shouldnt make a big difference. If you notice any hallucinations do let me know please
- gulcin_xata 2y agoTried with a video I previously watched and got a good enough summary, also liked the UI. Did you implement a RAG?
- GentleNapkin 2y agothanks! Cool that you like the UI since I feel like I'm not very 'artistic' if that makes sense. No, no RAG. I use Gemini 1.5 Flash as an LLM, and it has a very long context window (1M tokens). Because of that, I can feed the entire transcript into Gemini's context. I feel that's important to get good results.
