System prompt archive for Claude, ChatGPT, Gemini, and more

This repo is a large archive of verbatim system prompts from many AI assistants and agent products. The files are grouped by vendor and product, with separate captures for web chat, coding agents, voice modes, and tool-specific variants. It is useful when you want to compare how different systems are instructed, but it is not a build-time tool itself.
