What is the AI Coach Extension?
The Mindstone AI Coach Extension is a browser extension that brings Mindstone's prompt coaching directly into ChatGPT, Claude, Gemini, and Copilot — the AI tools you're already using at work.
When you're writing a prompt in one of these tools, the extension adds a small button next to the input box. Click it to get:
- Instant feedback on the quality of your prompt
- An improved version of your prompt, suggested by the coaching AI
- Your prompt score — so you can track your skill level over time, just like in the Prompt Sandbox
How to Install
- Visit the Mindstone AI Coach on Chrome Web Store.
- Click Add to Chrome and confirm the installation.
- Log in with your Mindstone account when prompted.
- The Mindstone button will appear automatically when you're on ChatGPT, Claude, or Gemini.
