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.
An AI agent that gives your whole team one shared memory
Pulls what matters from chats, email, files and meeting notes into a single searchable layer, so a question like "what do we know about this account" is answered with sources.
Knows whose deal it is, what has been decided and what is still open, and resolves ambiguous names by context rather than guessing.
Tracks commitments and deadlines and gives a heads-up when someone has not replied or work has stalled, so things do not quietly slip.
From drafting emails to attaching files, Tanka prepares the next action and hands it to you to review and send, rather than acting unchecked.
