prompts.chat: what it is, what problem it solves & why it's gaining traction

What it solves

It provides a centralized, open-source library of prompt examples to help users get better results from AI chat models like ChatGPT, Claude, Gemini, and Llama.

How it works

The project maintains a curated collection of prompts available in multiple formats (CSV, Markdown, and a Hugging Face dataset). It offers a web interface for browsing, a CLI, and an MCP server for integrating these prompts directly into AI tools. Users can also self-host their own private prompt library using a PostgreSQL database.

Who it’s for

Anyone using AI chat models who wants to discover high-quality prompts or developers who want to integrate a prompt library into their own applications or self-host a private collection.
