YouTube's auto-translate gives you gibberish.
You find a 2-hour talk by a Japanese AI researcher you really need to understand. YouTube's auto-translated captions read like a broken phone game — "the model has a high desire to think the thing". The subtitle pane scrolls past faster than you can read. You can't search it. You can't ask follow-up questions about it. And the actual content — the insight you came for — stays locked behind a language wall.
Paste the link. Get it in your language. Ask anything.
Summify auto-detects the source language, transcribes it cleanly, and produces a structured summary in your language. Translation happens at the sentence and paragraph level with full context — the output reads like native writing, not stitched-together caption fragments. The original transcript is always preserved alongside, so you can verify any line.
