Self-hosted AI governance and audit trail for regulated firms
The governance layer deploys in the firm's existing cloud account, so client files, patient records and financial data are processed within the firm's own environment and access controls.
Every query, model call, document access and response is timestamped, user-attributed and matter-linked, making firm-wide AI activity reconstructable and reportable.
Onboarding is built to deliver the artefacts a specific regulated vertical needs, such as WISP addenda, BAAs, ABA Opinion 512 summaries and Reg S-P governance policies.
Owners and managing partners get a web dashboard showing every AI interaction across the firm, with full session logs exportable for any date range.

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.
