Basin

Connect Basin to ChatGPT

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. Setting it up in ChatGPT takes a few minutes.

01

Sign in happens as you connect

You do not need an account first. Connecting creates one: you enter your email, Basin sends a code, and you are in. The code expires in 10 minutes.

02

Add the connector

Add Basin as a connector in ChatGPT and paste the endpoint.

When you connect, Basin asks for two things: read access to the spaces you own and the ones shared with you, and write access to files in those spaces, stamped with your email. Connecting shares nothing with anyone else. Sharing is always a separate step.

03

Choose Basin in a new chat

Open a new chat and select Basin from the tools menu. Select or mention Basin again when a later message needs fresh data or another action.

04

Set the standing instruction

Add one reminder to ChatGPT's custom instructions:

Check Basin at the start of every conversation.

This reminder does not select the app for you. Choose or mention Basin on each message that needs a new read or write.

05

Verify

Ask for something that needs a real read:

What is in my Basin library?

If it names your spaces, it is working.

If it did not work

No Basin tools at all.Basin is not switched on for this conversation. Turn it on under Settings, then select it from the tools menu for this message.
Fewer than 17 tools.ChatGPT is holding an old tool list. Remove Basin and add it again. Basin serves 17 tools; fewer means the list is stale.
The tools are there but the assistant never uses them.The standing instruction above is missing. Add the line. This one does not look like a connection problem, which is why it is the common one.
