AI Prompt Genius

AI Prompt Genius is a free Chrome extension for building and using a personal library of AI prompts. Instead of keeping prompts in scattered notes, users save them in one organized collection, then find and insert the right one when they are working in ChatGPT and other AI tools. It is designed for people who reuse prompts regularly, from writers and marketers to developers, and who want that library available everywhere. Prompts can be organized with tags and folders, imported from existing collections, and discovered or shared with others. The library syncs across a user's devices through Google sign in. The extension can also restyle the ChatGPT interface with themes such as SMS, hacker and cozy fireplace. The extension is free, and the site describes all features, including sync, at no cost. There are no paid plans published. Two points are worth knowing. The extension is available for Chrome only; Firefox is not supported because syncing depends on Google authentication. The source code is public on GitHub under a Creative Commons Attribution NonCommercial ShareAlike 4.0 license, which permits reuse with attribution but not commercial use, and the repository remains actively maintained.
