AI Prompt Library is a free Chrome extension that saves your best prompts —
with fill-in {{variables}} — and inserts them straight into
ChatGPT, Gemini and Claude with one click. Nothing ever leaves your browser.
No cloud, no subscription, no lock-in — just a fast, organized library that lives in your browser.
ChatGPT, Google Gemini and Claude, from one shared library — no switching tools.
Write {{topic}} or {{tone:friendly}} placeholders and fill them in with a live preview before inserting.
Right-click any message box to pick a prompt straight from a live menu of your library, grouped by favorites and category.
Type "/" in an empty message box, or press Ctrl/Cmd+Shift+L, to open the picker instantly.
Categories, tags, favorites, full-text search and usage tracking — built for libraries that grow.
Export your whole library to a JSON file any time, and import it back on another machine. No account needed.
Four ways in, one place your prompts live.
Write it once in the library manager — add a title, category, tags, and any {{variables}} you want to fill in later.
Right-click the message box, click the floating button, type "/", or press Ctrl/Cmd+Shift+L.
If your prompt has placeholders, a small dialog asks for the values with a live preview of the final text.
The finished prompt is inserted into the composer, ready to review and send.
There is no backend for this extension. Nothing you write is ever transmitted anywhere.
