# Summarizer

> Summarize links from videos, webpages, PDFs, and podcast feeds.

Summarizer turns links into clear summaries for YouTube videos, websites, PDFs, and podcast RSS feeds.
It also supports DOCX and PowerPoint files, and you can start from a right-click menu or from **Home → Summarize** in Utter.
