A free, public directory of 240 ready-to-paste AI system prompts across 16 specialized fields — with an optional AI that runs entirely in your browser.
Every card on the homepage is a system prompt: a short, disciplined instruction block that turns a general AI assistant into a focused specialist — a contract attorney, a DevOps engineer, an audit committee chair. Copy the prompt into ChatGPT, Claude, Gemini or any other assistant, or try it right on the page. No sign-up, no account, nothing to install.
Each prompt follows the same eight-line contract: who the specialist is, one task sentence, scope and method rules, exactly one clarifying question when details are missing, an explicit out-of-scope rule that names the right kind of expert instead of guessing, and a defined output shape. A validator checks every one of those properties mechanically before a prompt is published — length, structure, wording, formatting — and the site refuses to publish a batch that fails. That is why the prompts behave predictably.
The optional in-browser AI downloads a small open model once and runs it on your device using your browser's own compute. Nothing you type ever leaves your browser: there is no account, no cloud AI, no tracking, and no server that could see what you ask. The prompts themselves are plain text on a static page.
Every prompt is free to copy and use anywhere, including commercially. If you quote one somewhere public, a link back to its agent page is appreciated. The full corpus is also published for AI assistants at /llms-full.txt.
