Notion, Drive, Slack, Gmail, GitHub, Linear — plug in the tools you already use. Each workspace gets its own private brain, on its own database. Never mixed with anyone else's.
Every answer shows where it came from — the source, the version, the date. Click a citation to jump to the exact line. When Open42 doesn't know, it says so.
Save any useful answer as a Skill — a reusable mini-app. Ask once ('summarize this week's customer calls'), then anyone on your team can run it again with one click.
Reads transcripts from Gmail + Drive, groups by account, surfaces three product themes per account, and drafts the Monday digest.
Open42 connects your knowledge to your team. It cites sources, flags stale info, and turns any answer into a Skill anyone can run again.

Open42 handles users and metadata. gbrain runs the brain itself. Each workspace gets its own private brain on its own machine — no shared storage between workspaces.
Magic-link sign-in. Open42 holds the server session.
Sessions, connectors, chat routing, Skills.
Users, workspaces, and encrypted secrets.
Private brain per workspace, with scoped OAuth access.
Pages, chunks, and embeddings. Isolated per workspace.
gbrain is the open-source agent brain Garry Tan built to run his own daily work. Open42 pins it at a verified version, runs one isolated instance per workspace, and wraps it in the team layer it doesn't ship — auth, billing, connectors, UI.
How the brain stays accurate, where your data lives, and what a Skill actually is.
A Skill is a saved answer. Ask once — 'summarize this week's customer calls' or 'draft the weekly investor update' — and Open42 saves the steps as a reusable mini-app. Anyone on your team can run it again in one click. Skills are versioned, so each run uses the latest sources, not a stale snapshot.
Open42 only answers from your workspace brain. When the answer isn't in there, it says so — 'I don't have anything about this in your brain' — instead of guessing. Every claim links back to the exact source line, with the version and date it came from.
Each workspace gets its own brain — a private runtime with its own database. On Open42 Cloud, that's a dedicated machine with its own volume. Self-hosted, it's a Docker container with its own volume. There is no shared storage between workspaces, ever.
No. Your workspace brain never sees your real Anthropic or OpenAI key. It calls a proxy with a proxy token, and the proxy swaps in the real key on the way out — yours if you brought one, otherwise ours. The brain itself can't read or leak your keys.
Open42 Cloud is $20/month, billed monthly through Stripe. There is no free trial. You can cancel before the next renewal from workspace settings; payments already made are non-refundable except where required by law.
Open42 Cloud demo access is open. Start with a small docs repo, ask questions with receipts, and turn useful answers into reusable automations.
