README
Prompt Optimizer
**English** · [Italiano](README.it.md)
Prompt Optimizer is born from a simple idea: **help you write good prompts.** To do that it leans on Google **Gemini's free API tier** — and precisely *because* your prompt is sent to Gemini, it **anonymizes the sensitive data Gemini receives**: PII (emails, phone numbers, cards) is detected and masked **on your device** before the call, then restored in the output. Better prompts, without handing your personal data to the model.
Desktop app (Windows, via **Tauri**) — no backend of its own: everything runs client-side in the Tauri webview, with your API keys stored only on your device.
