Collaborative AI agents for production software engineering
A shared representation of your code, tickets, observability signals, people and deploy history that gives every agent one source of truth to reason from.
Purpose-built agents for support triage, SRE incident response, engineering root-cause work and QA validation, delegating questions to the right owner and keeping answers in one thread.
Changes fan out into parallel scenario runs that compare actual behaviour against expectations and hold the release gate until they match.
Work is split by owner automatically, with delegated questions tracked in a single workflow so nothing stalls in an inbox.

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.
