Zero to agent in minutes.
Connected out of the box
Ari is already wired into your Plain instance: the inboxes, threads, and tools your team already uses.
Add knowledge
Point Ari at your help center and internal docs. It cites the answer's source, so you can check its work instead of guessing at it.
Test and go live
Try Ari in the Playground: ask it questions in a private chat and see its reasoning. Before allowing it to resolve tickets, run Shadow Mode to see how it behaves on live threads.
Ari acts like an extra pair of hands on our team that never tires of the routine stuff. Its answers stay grounded and accurate since it pulls from the same resources we use in Support, freeing us up to focus on the threads that need a human touch.

Powerful out of the box. Customizable to your team.
Ari has earned its place on the team. Our customers get a faster response, our engineers get the threads that need real digging, and nobody waits in a queue for something we could have told them straight away.
