We're building the Company Brain we wanted to use.

Open42 is a self-hostable Company Brain built on gbrain. We answer with receipts, flag stale sources, and turn every useful answer into a one-click Skill anyone on the team can run.

We started this because the AI tools we tried at work were confidently wrong, expensive to debug, and built for one person chatting alone. We wanted something a team could actually trust: tenant-isolated, citation-first, honest when it doesn't know.
