Supported ChatGPT surfaces

This guide covers ChatGPT on web (chat.openai.com), the desktop apps (macOS / Windows), and the iOS / Android apps. All use the same underlying account configuration. The Affinity app is not supported in the OpenAI API or via custom GPTs. Those are different products. This guide is for the ChatGPT consumer / team / enterprise product specifically. For more information on how apps work in ChatGPT, see OpenAI’s Apps in ChatGPT help article.

​
Prerequisites

Affinity
  • Plan: Scale, Advanced, or Enterprise (required for API and MCP access).
  • Admin setup: None required by default. If an Affinity admin has disabled ChatGPT under Settings → Affinity MCP, ask them to re-enable it.
ChatGPT
  • Plan: Any plan, Free and up.
  • Admin setup: None. The Affinity app is published in the ChatGPT app directory, so developer mode is not required.

​
Connect the Affinity app

  1. In ChatGPT, open Apps from the left nav.
  2. Search for Affinity and select the matching result.
  3. On the app page, click Connect. Optionally enable Reference memories and chats, then click Sign in with Affinity to start the OAuth flow.
  4. Once connected, click Start chat to open a new chat with the Affinity app attached.
For details on what permissions Affinity requests and how to manage authorized clients, see Authentication.

​
Using the Affinity app in future chats

In any new chat, you can invoke Affinity in two ways:
  • Implicitly: reference “in Affinity” in your prompt and ChatGPT will pick the appropriate tools.
  • Explicitly: click the + button, choose More, and select the Affinity app.

​
Reconnecting

If you need to re-authenticate:
  1. Go to Apps and search for Affinity.
  2. Click the matching result, then click the gear icon → Disconnect.
  3. Click Connect to start a fresh OAuth flow.

​
Test your connection

Once connected, try one of these prompts in ChatGPT:
  • Find 3 companies I emailed in the last 30 days in Affinity.
  • Show me my upcoming meetings in Affinity.
  • Summarize recent activity on Acme Corp in Affinity.
If you see Affinity data in the response, you’re set. If not, see Troubleshooting.
