What is a ChatGPT app for AI visibility?
ChatGPT and Claude can both connect to outside services. In ChatGPT these are apps, in Claude they are connectors. Once connected, the assistant can call the service while it answers you, and some services can draw a small interactive card in the reply.
A ChatGPT app for AI visibility lets you ask about your brand's presence in AI answers from inside the assistant itself. Instead of logging in to a dashboard, you ask "Is my brand mentioned when people ask ChatGPT for the best tool in my category?" and the assistant answers from data Proofsource measured across the engines.
Proofsource builds this on its MCP server with a standard OAuth sign-in. You approve the connection on a Proofsource page that shows what the app may do, pick the workspace it can read, and can revoke it at any time from Settings.

What if I belong to more than one workspace?
You pick one on the Allow page, and the connection reads that workspace only. Connect again to switch.
How do I remove access?
In Proofsource, open Settings, then AI agents, and click Revoke next to the app. Removing Proofsource in ChatGPT or Claude also stops it on their side.
