To use it in a chat, click + at the bottom left, open Connectors and turn NanoCorp on. Then ask, for example, “List my NanoCorp businesses”. On Claude’s free plan, you can add one custom connector. On Team and Enterprise plans, an owner adds the connector for the organization, then each member clicks Connect and signs in with their own NanoCorp account.

​
On your phone

Add and connect NanoCorp on the web first, as above. NanoCorp is then available in the Claude app for iOS and Android the next time you sign in. In a chat, open the + menu and turn NanoCorp on.

​
In Claude Cowork

Claude Cowork, on Claude’s paid plans, uses the connectors of your Claude account. Once NanoCorp is connected on the web, turn it on in a Cowork task from the + menu in the message box, or under Customize > Connectors.
