The Take

It analyzes your repo with Gemini to draft a script, generates visuals with Flux, produces narration via OpenAI TTS, and renders the final cut with Remotion — all in minutes. Nice touches like private-repo support, multi-resolution exports, and per-video instructions show real product thinking; just watch for AI hallucinations in the script and expect to review edits before sharing.

Post Description

Hi HN, I built RepoClip, a tool that takes a GitHub URL and automatically generates a promotional video for the repository.

How it works: 1. Paste a GitHub repo URL 2. AI (Gemini) analyzes the codebase and generates a video script 3. Images (Flux), narration (OpenAI TTS), and background music are auto-generated 4. Remotion renders the final video

Tech stack: Next.js, Supabase, Inngest, Remotion Lambda, Fal.ai

I built this because I noticed many great open source projects struggle with marketing. Writing docs is hard enough — making a demo video on top of that felt like something AI could handle.

Free tier available (2 videos/month). Would love to hear your feedback.
