Open-source, human-in-the-loop workflow layer for on-premise AI
AI reads, extracts and drafts inside a workflow, but a named person reviews and approves each critical step so there is an audit trail by design.
Build processes with triggers, conditions, forms, tasks and approvals without writing code, and refine them as the process evolves.
Ready-made workflows for HR, sales, finance, procurement, IT, healthcare and more, usable as-is or as a starting point.
Apache 2.0 core with public code, so security teams can audit it and organisations can deploy on-premise or in a private cloud.
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.
