**Audio-to-LLM** runs once the transcription is generated. You provide **one or more prompts**; each prompt is executed against the **transcript text** from the same job using the configured model, yielding **one LLM response per prompt**. Use it to extract action items, answer questions about the recording, or run any text analysis you express in natural language.
-Unlike the built-in [Summarization](/chapters/audio-intelligence/summarization) feature — which produces a fixed-format summary — Audio-to-LLM lets you write **your own instructions**: ask for a summary in the exact format, tone, and level of detail your product needs, or combine a summary with other analyses (action items, compliance checks) in a single request.

-The chapterization model segments the audio
-into logical chapters based on the audio and content, and makes it easier to navigate long audios such as meeting recordings.
+Use [Audio-to-LLM](/chapters/audio-intelligence/audio-to-llm) instead. It is more powerful and fully customizable: you write your own prompts to segment long audio, generate headlines and summaries, or structure the transcript however your product needs.

-Each chapter will contain its start and end time, as well as a summary, headline, bottom line "gist" and keywords.
-
-## Usage
-
-Enable chapterization by setting the appropriate flag:
-
-
-```json Pre-recorded
-{
- "chapterization": true
-}
-```
-```json Live
-{
- "post_processing": {
- "chapterization": true
- },

-The transcription result will contain a `"chapterization"` key with the output of the model:
-
-
-```json Pre-recorded
