## Use Cases

* Podcast listeners: Get concise summaries of lengthy episodes to decide which are worth listening to in full
* Students: Summarize lecture and seminar recordings into focused study notes
* Researchers: Distill hours of interview recordings into actionable research insights

## Tips

* The AI model (\~300 MB) downloads once on first use, then caches in your browser
