Auto Chapters provides a "summary over time" for audio files transcribed with AssemblyAI. It works by first segmenting your audio files into logical "chapters" as the topic of conversation changes, and then provides an automatically generated summary for each "chapter" of content.

For more information on Auto Chapters, check out the announcement on our blog.

When submitting a file for transcription, simply include the auto_chapters parameter in your POST request, and set this to true.

When your transcription is completed, you'll see a chapters key in the JSON response, as shown on the right. For each chapter that was detected, the API will include the start and end timestamps (in milliseconds), a summary - which is a few sentence summary of the content spoken during that timeframe, a short headline, which can be thought of as a "summary of the summary", and a gist, which is an ultra-short, few word summary of the chapter of content.
