Use Radar Lab in ChatGPT

Radar Lab works inside ChatGPT. Ask a question in plain words and ChatGPT answers from your Radar Lab picks, competitor gaps and sponsor history, with a table of newsletters you can open.

Before you start

• A Radar Lab Pro account.
• A paid ChatGPT plan, such as Plus or Pro. If you don’t see Add custom MCP server, turn on Developer mode in ChatGPT’s settings. On a company ChatGPT workspace, your admin may need to allow custom apps.
• About two minutes.

Things to ask

• “Which newsletters should we sponsor? Use Radar Lab.”
• “Where are our competitors sponsoring that we aren’t?”
• “Which brands sponsor newsletters in our market?”
• “What’s new in Radar this week?”
• “Find newsletters in our market with over 10,000 subscribers.”
• “Where does our biggest competitor sponsor newsletters?”

Good to know

• Read-only. Your AI app can read your Radar Lab data. It can’t change anything, see billing, or contact anyone.
• Daily MCP limits: 10 new searches and 15 new brand lookups a day. Repeating one you already ran is free. Limits reset at midnight UTC.
• Check before you buy. Prices, subscriber counts and availability change, so confirm them with the publisher.
• Part of Radar Lab Pro. If your plan ends, the connection stops working until you upgrade again.
• To disconnect: ChatGPT → Plugins → Radar Lab → ⋯ → Uninstall.
