Paste any public GitHub repo or PR URL, get a ~60s narrated explainer video. No account, no email — just a shareable link and an MP4. RepoReel reads the code, writes a six-scene script, voices it with a local neural TTS, and renders real motion graphics — typography, stats, file-tree visuals — in about 90 seconds. Built for this Yard: every submission here needs a demo video, so I built the tool that makes them. This description is shorter than the video it took to explain itself.
