The problem
Creators constantly need their own videos back off the platforms they posted to, and the existing downloader sites are a minefield of popups, fake buttons, and sketchy ads.
What Claude Code did
Claude built a clean single-page downloader on top of yt-dlp: paste a link, pick video or audio, done. Downloaded files are wiped from the server after two hours, and a weekly cron updates the downloader engine itself, because platforms change their internals constantly and a stale engine is a dead tool.
The result
A genuinely free, genuinely clean utility that keeps working without anyone touching it. The self-update cron is the quiet hero: the tool repairs its own compatibility every week.
