# Summary Styles

Use `--prompt-type` in the CLI or select from the dropdown in the web interface. Add custom styles by editing [`summarizer/prompts.json`](https://github.com/martinopiaggi/summarize/blob/main/summarizer/prompts.json). Use `{text}` as the transcript placeholder.

## Multi-Step Workflow

For comprehensive analysis, chain multiple styles on the same video:

1. `Summarization` — quick overview
2. `Distill Wisdom` — extract key insights
3. `Fact Checker` (with Perplexity) — verify claims
4. `Mermaid Diagram` — visual reference

Transcripts are cached in memory, so re-summarizing the same source skips transcription entirely.
