How the summary is made
The summary is written from the video's transcript, not from the title or description. Audiotexta first takes the captions (or transcribes the audio with AI if there are none), then a language model writes a short summary, the key points and chapters with timestamps. Because it works from the actual words, it does not invent topics the video never covers; it can still miss nuance, so check the parts you rely on against the transcript.

Frequently asked questions
Can I summarize a YouTube video for free?
The transcript is free. The AI summary, key points and chapters are part of Pro, together with summaries of your own uploaded recordings.
How long can the video be?
Transcripts from YouTube captions work for videos of any length. Summaries handle several hours of speech.
In which language is the summary?
In the language of the video by default; on Pro you can also translate the transcript and summarise in your language.
Does it work without captions?
Yes. If a video has no captions, transcribe it with AI first and the summary is written from that transcript.
