AI Prompt Genius

AI Prompt Genius is a browser extension for building and managing a personal library of prompts used with AI chat tools. It installs as a Chrome extension and lets a user save, tag and organize prompts into folders for reuse across different AI agents. The extension has around 100,000 users and a 2.8 out of 5 rating from 161 ratings on the Chrome Web Store. It is offered by AI Prompt Genius LLC of Provo, Utah.

A user installs the extension, then clicks its icon to open the prompt library. Prompts can be organized with customizable tags and folders, decorated with custom themes, and found again through a search panel. A prompt variables feature lets a user insert placeholders into a prompt, including the newly added dropdown and number variable types. Saved prompts can be imported and exported to move them between devices or platforms.

The extension keeps a user's prompt library synchronized across multiple devices and works across a wide range of AI agents rather than a single chatbot. It supports 12 languages, so prompts and the interface can be used in a language other than English. AI Prompt Genius publishes its source code on GitHub and is offered as a free and open-source extension.

AI Prompt Genius is distributed through the Chrome Web Store as a browser extension carrying a Featured badge. Version 5.0.2 was updated on July 29, 2026, and the developer, AI Prompt Genius LLC, is based in Provo, Utah. The developer states that user data is not sold to third parties.
