Скачать или смотреть I Spent a Month Building This AI Learning Platform (And It's Completely Free)

I built GrokInterviews - a free, open-source learning platform that replaces the scattered "20 tabs + ChatGPT" workflow with a unified interface for technical learning.

What it does:
81,000+ technical questions across AI/ML, System Design, DSA, Web Dev, and Cybersecurity
AI-generated answers (streamed privately in your browser)
3.6M+ curated learning resources per question (YouTube videos, research papers, books, visual explainers)
Real-time voice interview practice with AI feedback

Tech Stack:
Frontend: Next.js 15
Database: Supabase → Cloudflare R2
AI: OpenAI SDK (client-side streaming)
Voice: OpenAI TTS + VAD
ML Pipeline: 4-stage agentic system with hybrid recommendation engine (semantic + lexical + tag + domain fusion)
Scraper: DeepSeek R1 on Modal (Nvidia A10/T4)

Total cost to run: $0

This isn't a ChatGPT wrapper - it's a complete learning platform with custom ML-powered resource ranking, agentic question generation, and sub-50ms recommendation latency. Built solo over a month as a fully open-source project.
