Core Features & Use Cases

  • URL and file summarization: Create concise summaries from URLs, local files, and YouTube/video links with best-effort transcript extraction.
  • Transcript-first workflows: When the user requests a transcript, return a tight summary first if the content is too large, then ask what section or time range to expand.
  • Provider-flexible extraction: Works across providers by extracting content (URLs/files/transcripts) and then injecting it as text for the model to summarize.

Quick Start

Run the summarize CLI on a link or local file to get an immediate summary.
