HeyOtto documentation
Everything to set up HeyOtto for your company — from your first login to your own mailbox app and single sign-on.
Quick start
- Getting started — sign up, confirm and set up your environment.
- Connect mailbox — connect Microsoft 365 or Gmail via OAuth.
Advanced
- Connect your own app — use your own Microsoft/Google app so consent stays within your tenant.
- Login SSO (OIDC) — lets your employees sign in via your company's IdP.

HeyOtto never sends on its own. He only creates draft replies — you always stay in control and have the final word.
