About this tool

Summarize captioned YouTube videos or TXT, SRT and VTT transcripts with AI. Choose key points, study notes or custom instructions. Transcripts are sent to Kie AI.

How to summarize a transcript

  1. Enter a YouTube link and fetch captions, or paste a transcript or upload TXT, SRT or VTT.
  2. Choose quick summary, key points or study notes, then optionally add instructions and an output language.
  3. Review the source, agree to AI processing, then generate and copy or download your summary.

Example

For a lecture, choose Study notes and ask for definitions and practical examples. Timestamped captions let the AI cite source moments.

Supported options and limitations

Up to 80,000 characters and limited free requests. YouTube captions may be unavailable or blocked. No audio transcription or visual analysis is included. AI may make mistakes. Transcripts and instructions are sent to Kie AI; pasted transcripts are not shared in a cache.

Common questions

Does this tool watch the video?

It summarizes captions, not images or audio. Paste a transcript if captions cannot be fetched.

Can I use a custom prompt?

Yes. Add up to 500 characters of instructions about focus, tone or format. Summaries are still restricted to the source transcript.
