Custom AI assistants that learn your data and travel with you across the web
Custom assistant builder: Create specialised assistants instead of relying on one generic chatbot.
Long-term memory: Assistants absorb knowledge from your connected sources and retain it for future tasks.
Multi-source ingestion: Add data from websites, PDFs, Notion and other connected tools.
Works on any website: Use your assistants inside the pages you already browse via the Chrome extension.

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.
