Free. Private. Local-only. PEAT is a browser extension that helps you save, organize, and reuse prompts across ChatGPT, Claude, and Gemini. It runs entirely on your computer, so your prompts never leave your device.
Coming soon to the Chrome Web Store! Until then, you’ll install it as an “unpacked” extension using the steps below. It takes about three minutes.
How to install
(3 minutes)
1. Download the zip. Click the copper-colored button above (or click HERE). Save “peat-2.0.2.zip” to your computer.
2. Unzip it. Find the file in your Downloads folder. Double-click it on Mac, or right-click and choose “Extract All” on Windows. You should end up with a folder named dist that contains a file called manifest.json.
3. Open your browser’s extensions page.
- In Chrome: paste
chrome://extensions/into the address bar and press Enter.
- In Edge: paste
edge://extensions/into the address bar and press Enter.
4. Turn on Developer Mode. Look for a switch labeled “Developer mode” (top-right in Chrome, bottom-left in Edge). Click it ON.
5. Click “Load unpacked.” Once Developer Mode is on, a new button will appear labeled “Load Unpacked” — Click that button.
6. Select the unzipped folder. Browse to where you unzipped the file as described in Step 2 above. Click on the folder containing manifest.json (do not double-click into it, just select it by clicking it once). Then click “Select” or “Open.”
7. Pin PEAT to your toolbar. Click the puzzle-piece icon to the right of your browser’s address bar, find PEAT in the list, and click the pin icon in Chrome (eye icon in Edge) so the PEAT icon stays visible.
That’s it. Open ChatGPT, Claude, or Gemini in a tab. Click into the chat box (i.e. no need to type anything – just click in the chat box to “focus” on it). Then click the PEAT icon in the top right of your browser. Pick any starter template (try “Explain like I’m 5”), fill in the provided fields, and click “Insert into Composer.” The prompt will appear in the AI’s chat box, ready for you to send.
What’s inside PEAT?
PEAT ships pre-loaded with 20 prompt templates designed for AI beginners, organized into categories like Frameworks (CRISPE, RACE, RTF), Learning, Productivity, Writing, Coding, and Career. You can edit any of them, add your own, search and filter your library, and export the whole thing as a JSON file you can back up or share.
Your privacy, in one paragraph
PEAT runs entirely on your computer. It does not send your prompts anywhere. It does not contact any server. It does not collect analytics. It does not track which AI tools you use or what you type. The full privacy details are on the PEAT Privacy page and the source code is open for inspection on GitHub.
