30 free system prompts prompts for ChatGPT, Claude and Gemini, starting with the most popular: Google Assistant - System Prompt, Advanced Agent Creator, GPT Builder. Pick one, fill in the placeholders and paste it into your AI assistant.
A system prompt is the hidden instruction that shapes how an assistant behaves before you type anything. This category collects published and leaked system prompts from the major assistants, among them Claude Opus 4, ChatGPT 4.5, Gemini 2.0 Flash, Meta AI on Llama 4, Microsoft Copilot, Le Chat and Perplexity Pro, so you can see how their makers steer tone, safety and formatting. Alongside them are system prompts you can use yourself: agent templates with goals and constraints, a decision agent, a GPT builder, prompt-refinement systems and a quality gate for the Gauntlet workflow. Read the published ones to learn the techniques. Then adapt a template for your own custom GPT, Claude project or API app, and keep it short enough to maintain.
