PromptPro: Local Prompt Optimizer

Improve prompts locally and reuse 66 bilingual templates across AI websites.

Improve AI prompts locally before you send them. PromptPro is a local AI prompt optimizer that helps you turn rough ideas into clearer, more structured prompts. Improve your prompts, reuse practical prompt templates, and build a personal prompt library across supported AI websites. Review the optimized result, insert it into the AI input box when available, or copy it manually before sending. **KEY FEATURES** • Local AI prompt optimization Improve prompt structure, clarity, tone, and detail using PromptPro's built-in browser processing. Your prompts are optimized locally without sending them to external AI services. • 6 prompt optimization styles Choose from Concise, Professional, Structured, Deep Analysis, Content Creation, and Code styles for different AI tasks. • 66 bilingual AI prompt templates Start with ready-to-use prompt templates for writing, productivity, coding, translation, marketing, research, analysis, and creative projects. • Search and reuse prompt templates Find templates by title, category, tags, descriptions, or keywords instead of creating prompts from scratch. • Personal prompt library Create, edit, search, favorite, import, export, and reuse your own AI prompt templates. • Optimization history and versions Review previous prompt improvements and restore earlier versions of your personal templates. • One-click insert or copy Insert optimized prompts into supported AI websites or copy them to the clipboard for manual use. **HOW IT WORKS** 1. Open a supported AI website. 2. Enter a rough idea or open the PromptPro extension popup. 3. Click PromptPro to optimize your prompt, or choose a template from the library. 4. Review the result and select Insert or Copy. 5. Send your final message yourself. **PRIVACY AND DATA HANDLING** PromptPro does not require an account. Prompt optimization runs locally in your browser using the extension's built-in processing logic. Your prompts are not uploaded to PromptPro servers and are not used for advertising or training. When using optimization or insertion features, PromptPro only reads the relevant text input on supported pages. The context-menu feature only processes text you explicitly select. Settings, personal templates, usage limits, and optimization history are stored locally in Chrome storage on your device. **USAGE LIMITS** • Up to 10 prompt optimizations per day. • Up to 10 personal templates. • Prompt optimization uses local built-in processing and does not call external AI models. **IMPORTANT NOTES** PromptPro works with supported AI websites that provide compatible text input fields. Website updates may affect compatibility. The extension does not work on unsupported websites and does not automatically send messages on your behalf. PromptPro is a privacy-focused AI prompt optimizer and prompt template library designed for users who want a clearer, faster, and more reusable AI workflow in the browser.
