AI Prompt Library is a local, server-free prompt manager for ChatGPT, Gemini and Claude. Save your best prompts once, then insert them with one click — no copy-pasting, no re-typing. WHY IT'S DIFFERENT • 100% local — everything is stored in your browser with chrome.storage. There is no account, no server, and no telemetry. Your prompts never leave your device. • Works everywhere you chat — ChatGPT, Google Gemini, and Claude, from one library. • Templated prompts — write {{topic}} or {{tone:friendly}} placeholders and fill them in with a live preview before inserting. FOUR WAYS TO INSERT A PROMPT • Right-click the message box → pick a prompt from your library (organized by Favorites and category). • A floating button on the chat page opens a searchable picker. • Type "/" in an empty message box to open the picker instantly. • Use the toolbar icon to search and insert from any tab. STAY ORGANIZED Categories, tags, favorites, full-text search, and usage tracking help you find the right prompt fast, even with a large library. A full-page manager lets you create, edit, duplicate, and organize everything. YOUR DATA, YOUR BACKUP Export your whole library to a JSON file any time, and import it back on another machine or browser profile. There is no cloud sync because there is no cloud — your prompts are yours alone. Open source. No ads. No upsells. No account required.
