Save the web, then chat, summarise and write from your sources
A floating save button plus Cmd/Ctrl+Shift+S captures pages, PDFs, videos and tweets, with native-style buttons injected on YouTube, X, Substack and Medium.
Cmd/Ctrl+Shift+K searches every saved link, PDF, tweet and video without leaving the page; Shift+R surfaces similar items in your library.
Ask questions across an entire project and get answers that point to the exact page and passage, so you can verify in one click.
Compare or switch between leading AI models with dual chat instead of stacking several subscriptions.

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.
