Use any AI model inside Microsoft 365 and Google Workspace without leaking data
Teams choose between GPT, Claude, Gemini, Grok, Llama, DeepSeek and self-hosted open-weight models, with new models added automatically as they are released.
Native add-ins for Outlook, Word, Excel, PowerPoint, OneNote and Teams, Marketplace apps for Gmail, Docs and Sheets, plus a browser extension, web console and Telegram bot.
Prompts are sharded and encrypted with AES-256-GCM on the client and routed through a zero-knowledge mesh, so the model never sees your identity or origin.
Role-based access, policy rules, PII/PHI handling and in-tenant audit log export mapped to frameworks such as HIPAA, SEC/FINRA and NYDFS, plus SAML/SCIM SSO and DLP rules.

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.
