Will this video make you smarter or dumber?
Paste a YouTube link. We read the transcript and hand back a report card: a brain score, who it's for, how fancy the vocabulary is, how much is filler, sponsor time, and whether the title is clickbait.
AI scoring is off. No Anthropic API key is set up yet, so you'll only see the measured stats (vocabulary, speaking speed, sponsor time from SponsorBlock). Add a key to
.env and restart to get the full report card.
