AI Prompt Genius
Open-source Chrome extension that turns your browser into a searchable, taggable prompt library for any AI chatbot.
Pick AI Prompt Genius if you live in ChatGPT or Claude and want a free, local-first prompt library you can search and tag without paying for a SaaS.
Skip it if you need a team prompt-ops platform with versioning, role-based access, or analytics across an organization.
AI Prompt Genius is a free, open-source Chrome extension that lets you build and organize a personal library of prompts you can fire into ChatGPT, Claude, Gemini, or any other web-based chatbot. It handles folders, tags, full-text search, prompt variables for dynamic inserts, keyboard shortcuts, custom themes, and cross-device sync via a Google Sheets backend.
It is squarely aimed at heavy prompt users who have outgrown copy-pasting from a Notes app or Notion page but do not want to pay for a hosted prompt-management SaaS. Because everything runs locally in the browser and syncs through your own Google Sheet, there is no vendor lock-in and no subscription. The 3.3-star Chrome Web Store rating reflects a sometimes-rough UX and the occasional sync hiccup, but with 100,000+ installs and an active GitHub repo (benf2004/AI-Prompt-Genius), it is one of the more credible free options in this niche.
It is platform-agnostic by design, so it works wherever you paste prompts, and the import/export plus 13-language support make it usable for teams sharing prompt collections informally. There is no API, no hosted backend of its own, and no underlying model, it is purely a power-user organizer layered on top of whichever chatbot you already use.
A solid pick for individual power users who want their prompt collection to follow them around the web without a subscription. The Google Sheets sync trick is clever and keeps you in control of your data, but the UX and ratings make clear this is a hobbyist tool, not a polished enterprise product.
