Basin

How your AI work comes together.

Connect your assistants, give the project a shared starting point, and let the next person or assistant build on the work.

01

Connect the tools you already use.

Connect each assistant to Basin through its supported setup. They can then work with the spaces your account can access.

You can connect unlimited assistants. Use your existing AI tools; Basin holds the shared context and work between them.

Connect each tool once. Use the same Basin account.

Supported tools and account requirements vary. Check your tool's setup guide.

02

Give the project a shared starting point.

A space holds the files and instructions for a project, team or client. Ask your assistant to save the current work: the brief, decisions and what needs to happen next.

You can start from an existing project. Bring in the useful context as you work rather than organising everything beforehand.

Example: asking an assistant to create a space for a project and save the brief into it.
Create a space for Northline. Save this brief and the decisions we've made.

Saved in Northline:

Design brief

A customer dashboard showing active projects, upcoming milestones and items awaiting approval.

First review: 18 September

Deliverables: Dashboard concept and mobile layout

Open question: Should clients be able to approve work directly?

I also saved the project decisions and next steps.

03

Pick it up through another assistant.

Open another connected assistant and ask about the project. It can retrieve the recorded context, use the existing instructions and save its contribution back to the same space.

For ongoing coordination, agents can check their Basin inboxes for changes and assignments. Configure that check in their workflow, or ask your assistant to check Basin in a chat.

Example: a second connected assistant reading the saved brief, building a review checklist from it and saving that back.
Check the Northline brief in Basin and prepare a review checklist.

The brief calls for a customer dashboard and a mobile layout. Here's the review checklist:

  • Can a client see which projects need attention?
  • Are upcoming milestones clear on desktop and mobile?
  • Is it obvious which items are awaiting approval?
  • Decide whether approval should happen inside the dashboard.
Save that checklist in Northline for the review.

Saved alongside the brief.

04

Bring someone else into the work.

Share the relevant information with a colleague, client or partner. Choose whether they can read or edit it and review the scope before sending the invitation.

Once they accept and connect their assistant, it can use the shared information through their own account. They can work at another company and use a different compatible tool.

Example: asking an assistant to share one file with an outside designer, and the access it proposes.
Share the Northline brief with Maya, our outside designer. She can read it, but keep the budget private.

Here's the proposed access for Maya:

Northline briefRead only
BudgetNot included

Send the invitation?

Yes.

Invitation sent. Once Maya accepts, her connected assistant can read the brief.

05

Follow the work as it changes.

Ask your assistant what changed, or inspect the files and activity in Basin. Contributions carry a record of who made them, and earlier versions let you follow how the work developed.

You can change access as the project evolves. Removing access stops future requests through it; it cannot recall information already retrieved.

Example: asking an assistant who has read a shared file and what changed in it.

Later, after Maya accepts and Alex updates the brief:

Has Maya seen the Northline brief? What's the latest version?

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.

Questions

Does the other person need to use the same AI as I do?No, and that's the point. You might be in Claude and they might be in ChatGPT or Gemini. Both read the same files. Basin sits between the tools rather than inside any of them. See the setup guides for each client's current availability.
Do I have to move my files into Basin?No. Most people start by asking an assistant to write down the context it keeps re-deriving — the setup page has a prompt for exactly that, run against a project you already have open.
Can their assistants write back?Only if you granted read and write. What they write is stamped with their verified account, so a shared file stays readable as a record of who said what.
What happens if I stop paying, or you disappear?Export gives you a zip of your current files in their original formats and folders, even on a cancelled account. Version history and activity logs are not included yet.
Can the other person see who I am?They see your account name on anything you wrote in a shared space. If you have no name set, Basin shows your verified email instead. Assistant names appear beneath the account as claims.
Something not working?Open the setup guide for your client. It has the current plan limits and the five common fixes.
