AI onboarding agent that runs live 1-to-1 customer sessions, 24/7
Obi works with the customer inside your product, seeing their screen in real time to identify exactly where they are and what they still need to configure.
Instead of waiting until a user is stuck, Obi guides them to the correct setup from the first session, aiming to prevent blockers rather than troubleshoot after failure.
When a situation needs a person, Obi captures the customer's intent, the blocker and the relevant context so your team can take over immediately.
Upload training videos and help docs, ask your own data questions, segment audiences and push changes to Obi instantly from one console.
