Thousands of support teams
Free to self-host, or fully managed
Scale from solo to enterprise
AI agents that work like teammates

An AI teammate on every screen

  • Agents sit beside your replies, worklists, automation editor and command bar -- every surface, from the moment you install
  • An agent reads what you have open and works on it with you, instead of describing a change and leaving you to make it
  • Cerb's own documentation ships as an agent filesystem, so it answers out of the same manual you'd read
  • A terminal into the platform lets it look up the record types and fields your installation actually has, rather than guessing
  • Bring your own model -- a dozen providers work out of the box, and one running on your own hardware works the same way
  • Not a chat window bolted onto the side: an agent is a worker record that owns tickets, is @mentioned, and joins groups
