Prompt Natus - Free Prompt Optimizer

One-click prompt optimization for ChatGPT, Claude, Gemini & more. Use your own API key. Always free and simple to use.

Features & Capabilities

Prompt Natus turns your simple messages into clear, well-structured prompts that help AI chatbots like ChatGPT, Claude, Gemini, Perplexity, and others give you better, more accurate answers. It works quietly beside your chat window and improves your prompts with one click.

1️⃣ 100% Free with Your Own API Key Instead of subscriptions or limited free plans, Prompt Natus connects to your personal Google API key. This makes it completely free and almost unlimited to use—hundreds of optimizations per day with zero restrictions. You stay in full control: no accounts, no data collection, no costs. Everything runs directly from your browser, keeping your key private and your data local.

2️⃣ Better Prompts, Better Results Prompt Natus automatically upgrades your prompt structure using professional prompt engineering logic—defining role, context, and clear instructions for the AI model. The result: more relevant outputs, fewer retries, and a smoother workflow across all chatbots.

3️⃣ Simple to Use, Fast to Learn After setup, a small blue button appears next to the chatbot’s text box. Click it to open the sidebar, edit your prompt, and hit “Optimize.” The improved version appears instantly and can be sent back with one click. You can also save and reuse past optimizations from your local history.

4️⃣ Private by Design Your prompts and history never leave your device. The extension stores up to 500 entries locally and sends only what’s necessary to the Google API. No tracking, no external storage, and the code is open-source for full transparency.

5️⃣ Clean and Non-Intrusive Interface The floating button stays out of your way, adapts to each platform’s layout, and the optimization dashboard includes shortcuts, clear feedback, and smooth animations for a polished experience.

6️⃣ How to get my Google API Key?

Getting your Google API key is simple, fast, and completely free. There are no hidden fees or automatic payments, and you can remove or replace your key anytime in the extension settings.

  1. Go to https://aistudio.google.com
  2. Click “Get started” at the top right and sign in with your Google account.
  3. In the left sidebar, click “Get API key.”
  4. Click “Create an API key.”
  5. Copy the key that appears.
Then, open the Prompt Natus extension settings (or simply click its icon in your browser toolbar), and paste your key into the settings panel. That’s it—your setup is complete. Your key stays fully private and is stored only on your device.

🔵Prompt Natus gives you the power of expert-level prompt creation without subscriptions, limits, or clutter—just install, connect your key once, and start getting more from every AI chat.
