OnlyPrompts.ai is a searchable library of more than 15,000 professional, copy-paste-ready prompts for ChatGPT, Claude, Gemini, and Midjourney. Designed to help beginners get useful results without a prompt-engineering background, its prompts are formatted for immediate use: users fill in bracketed details and submit them. The library spans 33 categories covering work, everyday life, and generative media, with browsing by category or keyword search.

Anyone can access the free tier instantly, without an account or signup. It includes more than 4,600 prompts across categories, as well as a collection of prompts sourced from creators on X.com, with credit; that collection is described as still being tested. Premium access unlocks the full library and is available for a one-time payment of $2.99, with no subscription or renewals. Users can also receive lifetime Premium access free by following the site’s instructions to obtain a Founders’ Code through X. The library works in a web browser on desktop and supported mobile devices, with no installation required. OnlyPrompts says its collections are growing weekly.
