WHAT SUMMARIO DOES
─────────────────────────────────────────────

Summario reads the transcript of the YouTube video you're watching
and uses AI to generate:

 • A concise summary — the full video distilled into 3 paragraphs
 • Key takeaways — the 5 most important points, ranked
 • Clickable timestamps — jump straight to the moments that matter
 • Interactive chat — ask follow-up questions about the video
 • Quick summary mode — TL;DR in 20 seconds via the extension popup

All inside the YouTube sidebar. No tab switching. No paywalls
to read basic summaries.
