AI active-reading companion for web articles and YouTube
Embedded AI questions check whether you are genuinely absorbing a page instead of skimming past it.
Highlight and annotate articles, then keep those notes organized so they are easy to revisit.
Ask questions directly about the page content and get answers in place, deepening comprehension on the spot.
Live AI-generated questions appear while you watch YouTube, turning video into an active-learning exercise.

The AI workspace where teams and agents get work done together
Combine docs, wikis, projects, and databases into one structured system of record that stays linked as your content grows.
Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.
