Direct answer
The quickest way is the PromptPal Chrome extension, which adds your prompts inside ChatGPT. To let ChatGPT use PromptPal directly, turn on Developer mode in ChatGPT (Settings › Apps & Connectors › Advanced settings), create a connector with the address https://mcp.promptpal.app and OAuth sign-in, then choose Allow. The connector needs a paid ChatGPT plan and a PromptPal Starter or Pro plan.
Option 1: the Chrome extension
The PromptPal Chrome extension works in Chrome, Edge and Brave. It adds an "Improve with PromptPal" button inside ChatGPT, Claude and Gemini, and lets you pick prompts from your library without leaving the chat. It's free to install.
Option 2: connect PromptPal to ChatGPT
A connector lets ChatGPT call PromptPal itself: write prompts in your style, search your library and save prompts.
- In ChatGPT, open Settings › Apps & Connectors › Advanced settings and turn on Developer mode. Custom connectors need ChatGPT Plus, Pro, Business or Enterprise.
- Back in Apps & Connectors, choose Create. Name it PromptPal and paste https://mcp.promptpal.app.
- Set Authentication to OAuth, tick "I trust this application", then choose Create.
- ChatGPT opens a PromptPal window. Check it's your account and choose Allow.
What you can ask
- "Use PromptPal to find my growth strategist prompt."
- "Use PromptPal to write a prompt for a product launch post, for LinkedIn."
- "Save this prompt to PromptPal as Weekly update." ChatGPT asks you to confirm before saving.
FAQs
Which should I use, the extension or the connector?
The extension is quickest and works on any PromptPal plan. The connector suits people who want ChatGPT to look up, write and save prompts by itself, and needs paid plans on both sides.
Does the connector cost PromptPal credits?
Writing a new prompt uses PromptPal credits, the same as in the PromptPal app. Searching and reading your library doesn't.
How do I disconnect ChatGPT?
Open Connect in your PromptPal dashboard and choose Disconnect on the ChatGPT card, or remove the connector in ChatGPT's settings.
