Why download YouTube subtitles?
YouTube's caption track is read-only inside the player — you can't search it, you can't copy a quote with its timestamp, you can't translate the whole video into your language at once. Downloading the subtitles unlocks all of that: read them in a clean reader, save them for offline study, or pull a specific line into your notes.
YouTube Translate handles both subtitle types. Manual subtitles uploaded by the creator come through verbatim — the highest-quality option, often already proofread. Auto-generated subtitles from YouTube's speech recognition are extracted and cleaned. For videos with no subtitle track at all, AI transcription generates one in 1-3 minutes.
