What is prompts.chat?

prompts.chat, formerly known as Awesome ChatGPT Prompts, is a community-curated collection of example prompts for AI chat models. The README describes itself as the world's largest open-source prompt library for AI, and notes that the prompts were originally created for ChatGPT but work with any modern AI assistant, listing Claude, Gemini, Llama and Mistral alongside it. In plain terms, a prompt is the instruction you type into a chatbot, and this project gathers good ones in one place so you do not have to figure out the wording from scratch. It works as a website plus a shared dataset. You can browse prompts on the prompts.chat site, view them in the PROMPTS.md file in the repo, download them as a prompts.csv, or use the Hugging Face dataset version. New prompts are submitted through prompts.chat/prompts/new and sync back to the repo automatically. The README also describes a free interactive book that teaches prompt engineering, a kids version called Promi for ages 8 to 14, a self-hosting setup that lets organizations deploy their own private prompt library with custom branding, themes and authentication via GitHub, Google or Azure AD, a command-line tool launched with npx prompts.chat, a Claude Code plugin, and a Model Context Protocol server that can be used remotely or locally inside AI tools. You would actually use this if you are learning to write better prompts, looking for a starting point for a specific task such as acting as a tutor or a code reviewer, or running an internal AI tool at a company and want a curated prompt set with privacy. The repo's primary language is HTML, and the self-hosting flow uses Node tools like npx and npm.
