Questions

What can the AI do in Cling?

The AI can read documents, templates, end customers and projects. It can create end customers and draft documents from templates, send documents for signing and delete documents.

Does the AI see my Cling credentials?

No. Your Cling login details are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on. Sending a document notifies the recipients right away and deleting one is permanent, so send_document and delete_document can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Cling account.

Why does Cling need my email and password?

Cling's API works with a short-lived token that is issued when you sign in. HeyMyApps uses your email and password to get that token automatically, so you do not have to renew it. We recommend creating a separate Cling user for the AI with only the rights it needs.
