Can I extract text from local files and web pages using the same tool?▼

What is the best way to summarize podcasts and audio transcripts quickly?▼

The best way to summarize podcasts is to pass the podcast URL to the summarize tool, which extracts the transcript and applies its summarization logic to produce a concise text output.

Does the summarize CLI support JSON output for automated workflows?▼
