Single-method tools fail the moment YouTube changes something. SmartTranscript tries six different ways to get your text before it gives up.
If captions aren't reachable, we try the transcript panel, then the internal API, then a public fallback, then speech-to-text — automatically, in order.
Region-locked auto-captions, disabled subtitles, or oddly formatted tracks — the chain is designed to route around exactly these failure cases.
You never see "no transcript available" and have to try another tool — the extension already tried the next method for you.
Whichever method succeeds, you get the same clean, timestamped, searchable text.
Most tools rely on a single method (usually YouTube's caption API). When that endpoint is rate-limited or the video has no captions, they simply fail.
Six: official captions, page DOM scraping, the internal player API, a public API fallback, and on-device speech-to-text as a last resort.
Yes, as long as the replay is publicly viewable, the same fallback chain applies.
No hard cap on caption-based extraction. Speech-to-text fallback is optimized for videos up to a few hours long.
