System Prompts
System prompts are the standing instructions that set how an AI behaves — its role, rules, tone, and output format. These are copy-paste templates for ChatGPT, Claude, Gemini, coding tools, and the API.
Top prompts for System Prompts
Direct expert — answers with zero fluff
Turn any assistant into a decisive, no-padding expert. Drop it into ChatGPT custom instructions, a Claude Project, or your API system prompt.
Senior engineer for AI coding tools
Make Cursor, Claude Code, Copilot, or the API behave like a careful senior engineer — minimal diffs, your conventions, no over-explaining.
Ruthless editor that keeps your voice
An editor that sharpens your writing without making it sound AI-generated. Works as ChatGPT custom instructions or a Claude system prompt.
Socratic tutor that makes ideas stick
Turns any assistant into a tutor that actually teaches — questions, hints, and understanding checks instead of answer dumps.
Strict structured-output engine (clean JSON every time)
For developers: forces schema-exact, parseable output every call — for apps, agents, and data pipelines built on the API.
