AI Prompt Genius
Open-source Chrome extension for building a searchable, tagged library of reusable AI prompts.
In short
AI Prompt Genius is a free, open-source Chrome extension that organizes reusable AI prompts with tags and folders. It injects templates into ChatGPT and syncs via Google Sheets.
Pick AI Prompt Genius if you live in ChatGPT in the browser and want a free, hackable way to organize a growing pile of reusable prompts.
Skip it if you need team prompt management, an API to wire prompts into apps, or a polished commercial-grade tool with support.
AI Prompt Genius (originally ChatGPT Prompt Genius) is a free, open-source Chrome extension that turns the browser into a personal prompt management system. It lets you save prompts to a local library, organize them with tags and folders, search across the collection, and inject reusable templates with dynamic variables into ChatGPT and other LLM chat interfaces. A Google Sheets sync option keeps the library mirrored across machines.
The target user is the heavy prompt tinkerer who has accumulated dozens of go-to system prompts, jailbreaks, and content templates and is tired of pasting from a notes file. It is fully free with no upsell, ships in 13 languages, supports import/export, and has a public GitHub repo. The trade-off is that it is a browser extension rather than a hosted service, so there is no API, no team sharing, and the experience is bounded by what a Chrome extension can do inside the host chat UI.
With 100,000+ installs but a middling 3.3-star rating across 159 reviews, the project is clearly in use but uneven. Updates are recent (v4.3.5 in early 2026), and because the code is open, power users can fork or self-modify rather than wait on the maintainer.
A useful little power-user utility that does exactly one thing — local prompt library plus injection — and does it for free with the source open. The 3.3-star rating is a fair warning that polish is uneven, but for solo tinkerers it beats juggling a Notion page of prompts.
