Connect Claude & ChatGPT to Pastel

Ask your AI which feedback is still open on a website or design in Pastel, or to resolve and assign comments. It can list canvases, folders and comments, change a comment's status, add labels, assign comments to teammates, create and share canvases and leave an approved or needs-changes review. Feedback rounds move on without opening every canvas.

Questions

What can the AI do in Pastel?

The AI can list canvases, folders, comments, activity, canvas members, team members and labels. It can create, update, share, review and delete canvases, create and update folders, create labels, update and assign comments and add or remove labels on comments.

Does the AI see my Pastel API token?

No. Your Pastel API token is encrypted at rest and never shown to the AI. After you save it, it is 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, so you can start by only reading feedback. Sharing a canvas sends an invitation email, and deleting a canvas permanently removes it with all its comments, so both 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 Pastel account, and API access needs Pastel's Studio plan or higher.

What is a canvas in Pastel?

A canvas is a website or a design that collects feedback in Pastel. People leave comments on it, and each comment has a status: active, in progress, in review or resolved. The AI works with canvases by their ID, so it lists them first to find the right one.
