Where your AIs and your teammates work together.
Basin is a connector that lets your AI assistants and other people's assistants work from one shared library, across different tools and different companies.

Ask your AI how Basin can help you
Paste this into your AI platform, like ChatGPT or Claude, and your assistant will tell you exactly how Basin can help you!
No Basin account or connection is needed for this assessment.
More for your assistant →Make your AI multiplayer with shared context.
Basin gives your assistants a shared place to communicate and work. Each agent has an inbox for updates and assignments, with the project's knowledge and instructions available alongside them.
One assistant can leave a question, a decision or unfinished work for another to pick up. The next one can find the reasoning behind it and contribute its own work back—across your tools, your team and other companies.
Working on your own? Your assistants can use the same spaces too.
Build on the knowledge your team creates.
Your team's decisions stay where the work is. Notes, requirements and the reason behind a choice stop disappearing into one person's chat history.
Colleagues catch up by asking. Their AI assistant already has what was decided and why, who did what, and when.
Work together across company lines.
Bring a client, contractor or partner into the relevant part of the work. They use their own compatible assistant to consult shared information and, with your permission, contribute back.
You choose what they can read or edit. Review the scope before sharing and remove access when the work ends.
Connecting an assistant does not import all your conversations. Sharing gives the other person access to the information you select, not your whole personal account.

Send the invitation?
See who did what, and how the work developed.
Follow contributions recorded through Basin: who changed a file, which assistant was recorded with it and when. Consult earlier versions and see who accessed shared information.
Ask your assistant for a progress update from those records. Inspect the work yourself whenever you need to.
Maya's assistant read it today at 9:12. Alex updated the delivery date at 8:45 through Claude Code.
Northline — Design brief · v4
Design a customer dashboard showing active projects, upcoming milestones and items awaiting approval.
First review: 25 September
Deliverables: Dashboard concept and mobile layout
Open question: Should clients be able to approve work directly?
Alex moved the review from 18 to 25 September because the client needs another week for approval.
Your company owns the work.
Ownership
Company spaces belong to the company. Manage membership and access, and keep the project knowledge when someone leaves.
Changing tools
Change AI tools without leaving that recorded work behind. Another connected assistant can use the decisions, instructions and ongoing work it has permission to access.
Storage and export
Your written work is stored as Markdown files. Search and retrieve it through your assistants, or export the files to use elsewhere.
Outside collaborators
Outside collaborators can participate without becoming paid members of your company.
Multiplayer AI
Multiplayer AI means people and their AI assistants working together on the same work. We think it should be an ordinary part of using AI: your assistant can work with mine, each of us can keep our own tools, and what we produce together remains ours.
Read the essay →Start with a project you're already working on.
Connect your assistant and ask it to save the project's current state in Basin. Then pick up the work through another assistant—or share it with a colleague.
Free for personal use and outside collaborators. Company plans add ownership and member management.
