About
Transform your AI prompts instantly—100% free, forever.
Prompt Natus optimizes prompts for ChatGPT, Gemini, Claude, Perplexity, and other AI platforms. One click, better results.
How the optimization works:
Uses AI to refine prompts. It understands your goals, improves clarity and structure, adds reasoning steps, preserves your content and examples, defines clear output formats, and breaks complex tasks into clear steps.
It transforms simple prompts into detailed, structured instructions for better results.
Why is it free?
You use your own Google API key. That makes it free and nearly unlimited thanks to Google’s free tier—no server costs, no ads, no subscriptions.
The difference?
Most similar extensions offer small free quotas and charge around $10/month for more. The key difference: the API key. By using your own key, you get unlimited, free access without paying a subscription.
Your data stays private.
Your API key and prompts are stored locally in your browser. They never touch our servers.
