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.
