FAQ

Common questions

What does a YouTube video summarizer do?

Sumiza reads a YouTube video's captions (or transcribes the audio if there are none) and uses AI to turn it into a structured summary — a short TL;DR, a chapter-by-chapter breakdown with timestamps, key takeaways, and action items — so you can decide if a video is worth watching in seconds instead of minutes.

Is Sumiza free to use?

Yes. You can try one video for free with no signup, and the Free plan includes a monthly summary after you create an account. Paid plans add more summaries per month and longer video support.

Does it work on videos without captions or subtitles?

Yes. If a video has no captions, Sumiza automatically transcribes the audio using Whisper speech-to-text, so the summarizer still works.

Can I get the full YouTube transcript instead of a summary?

Yes — the YouTube to Text tool converts any YouTube video into the complete, word-for-word transcript, not just a summary.

What languages does Sumiza support?

Sumiza works on YouTube videos in any language supported by YouTube captions or Whisper speech-to-text, which covers dozens of languages.
