TeamBrain is a shared workspace for teams that use AI. It keeps a team's docs, tasks and decisions in one place that Claude, ChatGPT or any other compatible AI can read and update. The company's argument is that most AI tools were built for one person at a time, so knowledge ends up locked in individual chat windows.
The product is published by Craftwell Labs LLC, which says it built TeamBrain to solve its own problem. Its project manager, designers, VAs and clients now work with AI off the same organized knowledge. TeamBrain is not a chat app that replaces existing AI tools; it sits in the middle of a team's current setup.
Teams upload the files they work from, such as docs, briefs, notes and deliverables. They then keep using their own AI and tell it to save work into TeamBrain instead of leaving it in the chat. An instruction like "Write the draft and file it under the client" is the example the site gives.
TeamBrain stores everything as plain markdown and speaks MCP natively, so AI clients connect without custom plugins. As work happens it tracks changes and records decisions with the reasoning behind them. When a teammate points their own AI at the same workspace, they see the files and updates right away, with no handoff meeting.
Beyond document storage, TeamBrain includes a working project space. It has a kanban board, a shared calendar, comments on docs, asset attachments, collections that group items by campaign or client, and a dashboard showing what is moving and what is stuck. The site says the team's AI can operate each of these tools, such as creating tasks or filing assets.
A decision log captures every change with the reason behind it. Each morning, every person gets an email listing what is on their plate and what changed. Guest accounts bring clients and contractors into just their own material, and access controls limit what each person sees.
On data handling, the company says it never reads or trains on customer data. Deleted items stay in trash for 30 days, and every file can be exported as markdown.
TeamBrain is a shared workspace for teams and their AI. It stores docs, tasks and decisions as plain markdown that Claude, ChatGPT or any AI that supports MCP can read and update. It also includes a built-in project space with a kanban board, calendar and dashboard.
Starter costs $12/month or $10/month on yearly billing and includes 5 seats. Pro costs $24/month or $20/month yearly with 20 seats. Max costs $49/month or $40.83/month yearly with 50 seats.
The pricing page shows no free plan and no free trial. It lists only the three paid plans, Starter, Pro and Max. Cancellation is possible at any time, with access kept through the paid period.
No. Team members keep using their own AI and connect it to TeamBrain, then tell it to read from or save to the shared workspace. TeamBrain is not a chat platform that replaces them.
It works with Claude, ChatGPT and other major AI clients, plus anything that connects over MCP or its API. The site also mentions reaching it from Claude Code and from an AI in Slack.
The company says data is private to the team, protected by access controls and encrypted in transit, and that it does not train AI on it. Everything is plain markdown, so every file can be downloaded at any time, including after cancelling.
Guests are clients or outside collaborators who can read and comment on work in a workspace without taking a seat. Any AI a guest uses runs on the workspace owner's plan. Starter includes 50 guests, Pro 250 and Max 1,000.
It is aimed at small teams, with Starter covering 5 seats and 5 workspaces. The site also names freelancers, founders and startups, and agencies as users. Teams can start with a few people and move up a plan when they outgrow the seats.
