Does Gemini Have a Prompt Library?
Gemini has no built-in prompt library. If you reuse the same prompts, a research brief, a summarizer, a brand-voice template, you either retype them, keep them in a separate document, or scroll old chats to copy one out. There is no native place inside Gemini to store, organize, and reuse prompts. (Gems let you build custom assistants, but they are not a quick, insert-on-demand prompt catalog.)
AI Toolbox adds that library. It ships with a curated catalog of expert prompts organized by category, and it lets you save your own prompts and insert any of them into the Gemini prompt box instantly, right inside gemini.google.com.
How the Prompt Library Works
The library is built for fast retrieval and reuse.
Install AI Toolbox from the Chrome Web Store and open gemini.google.com.
Open the Prompt Library from the AI Toolbox floating button.
Browse by category or search by title, then click Use Prompt to drop it into the Gemini composer, or Save Prompt to keep it in your own set.
Type // in the Gemini prompt box to insert any of your saved prompts without opening the panel.
The catalog includes a fresh Prompt of the Day, category filters, search, and favorites, so finding the right prompt for the task takes seconds.

Your Own Saved Prompts and the // Shortcut
Beyond the curated catalog, you can save your own prompts and call them by typing // in the Gemini composer. Build a small set of the templates you use daily, a research outline, a tone rewrite, a data-extraction brief, and insert any of them in two keystrokes. Pair the library with Smart Tags and Context Mentions to keep the chats those prompts produce organized and connected. AI Toolbox is also available for the ChatGPT and Claude modules.
Free vs Premium for the Prompt Library
The free plan opens a starter slice of the curated library, with the Prompt of the Day and a set of categories you can use, plus the rest shown as locked previews. Premium ($9.99/month or $99 one-time lifetime) unlocks every category and prompt, and the same plan unlocks unlimited full-text search, folders, and Smart Tags on Gemini. If you use more than one AI, the All Access Lifetime ($149) covers the ChatGPT, Gemini, and Claude modules in one purchase and saves $148 versus three single-platform Lifetimes. All paid plans include a 14-day money-back guarantee.

Who the Prompt Library Is For
Researchers keep summarization and extraction prompts ready to fire. Marketers and writers store brand-voice briefs and content templates. Developers reuse code and review prompts. Anyone with a repeatable workflow stops rebuilding the same prompt and starts from a saved one every time.
