System prompt generator and prompt enhancer
Enter your web address and the AI reads what you do, how you sound and who you talk to — then writes a system prompt with role, tone, rules, escalation and what the AI must never do. Already have a prompt? We improve that instead.

FAQ
What is a system prompt?
It is the instruction that governs how an AI model behaves: its role, tone, the rules it follows and what it must never do. A good system prompt is the difference between an AI that answers correctly and one that makes things up.
What do you read from my domain?
We read the public text on your home page and a few key pages to understand what you offer, how you express yourself and who your audience is. Nothing is stored and we never log in anywhere.
Does it work on every website?
No. Sites that block robots or render all content with JavaScript cannot be read. The tool says so plainly and lets you describe the business yourself instead of guessing.
Can I use the prompt in ChatGPT or Claude?
Yes. The output is plain text and works in ChatGPT, Claude, Gemini or whichever platform you use — including your own AI agent in ZyndraAI.
