Connect ChatGPT

Add one URL, then sign in to Grabblist — no API key or token to paste

verified_userSecure sign-in with OAuth

Your assistant opens Grabblist in the browser, you sign in and approve read and write access. Your password never goes to the assistant, and you can disconnect it at any time.

infoWhich ChatGPT plans can connect today

Until Grabblist is listed in the ChatGPT app directory, you add it yourself with ChatGPT's developer mode. OpenAI offers developer mode with full (read and write) access on Business, Enterprise and Edu plans, and with read-only access on Pro, so on Pro ChatGPT can read your Grabblist but not save to it. On Business, creating a custom app is usually limited to workspace admins and owners. Plan availability and permissions are set by OpenAI and your workspace, and can change.

1

Turn on developer mode

In ChatGPT on the web, turn on developer mode in Settings. On Business, Enterprise and Edu, a workspace admin or owner allows custom apps first, and may need to create the app for you.

Check the connection
