Highlight any sentence, get an instant, page-aware AI explanation
Highlight a confusing sentence and receive a short explanation without leaving the page or opening another tab.
Choose how much surrounding page text is sent along with your selection to balance answer quality against API cost.
When a selection plus page context exceeds the request size limit, the extension automatically lowers how much page content it ingests.
Accidental highlights created by double-clicking are ignored, so the tool only fires when you deliberately select text.

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.
