  Supercharge your AI interactions with Prompt Optimizer, the ultimate browser extension for refining your prompts for Google Gemini and OpenAI's GPT models. Whether you're a developer, writer, or enthusiast, this tool helps you craft clearer, more effective prompts to get the best possible results from large language models.
  
  KEY FEATURES:
  
  ✔️ In-Page Floating Toolbar: Don't break your flow. Simply select text in any textarea or input field on any website, and a context-aware toolbar appears with powerful, one-click optimization suggestions.
  
  ✔️ Popup Prompt Pad: Use the extension popup as your dedicated prompt engineering scratchpad. Write, paste, and iteratively refine your ideas with a full suite of tools. Compare the original and optimized versions side-by-side to see the improvement instantly.
  
  ✔️ Advanced Prompt Engineering: The suggestion "pills" are more than just simple commands. They are powered by sophisticated meta-prompts designed to elicit high-quality, structured responses from AI, incorporating best practices like persona assignment, clear constraints, and logical structure.
  
  ✔️ Multi-Provider Support: Bring your own API keys for Google Gemini or OpenAI. Your keys are stored securely in your browser's local storage and are never transmitted to our servers.
  
  ✔️  Guest Mode: Want to try it out first? Use Guest Mode for a limited number of free daily prompt optimizations without needing an API key.
  
  ✔️ Secure & Private: We prioritize your security. API keys are handled exclusively in the background, never exposed to web pages. For an extra layer of security, enable AES-256 encryption with your own passphrase.
  
  Stop getting mediocre results from your AI. Install Prompt Optimizer and start crafting expert-level prompts today!

  Optimize your prompts for AI models like Gemini, GPT, and local Ollama.
  
  Prompt Optimizer is a Chrome extension that helps you craft clearer, more effective prompts for large language models—without leaving the page you're on.
  
  What's new in 1.1.0
  
  • Workspace UI refresh for popup, options, and in-page preview
  • Custom prompt templates (toolbar / popup / both)
  • Text template library with in-page trigger expansion
  • Ollama (local) provider — run optimizations against your own machine
  • Improved built-in optimization pills and popup quick actions
  
  Important: Guest Mode has been removed. If you previously used Guest Mode, open Options and set up Gemini, OpenAI, or Ollama (Local). Your other settings are kept after the update.
  
  KEY FEATURES
  
  • In-page floating toolbar — Select text in a textarea, input, or contenteditable field on any site. A compact toolbar appears with one-click optimization actions.
  
  • Popup Prompt Workspace — Open the extension popup to write, paste, and refine longer prompts. Compare original and optimized text side by side before you apply changes.
  
  • Advanced prompt engineering — Built-in suggestion pills use structured meta-prompts (persona, constraints, format) so models return higher-quality results—not generic rewrites.
  
  • Custom optimization templates — Save your own instruction templates in Options and show them on the toolbar, popup, or both.
  
  • Text template library — Store reusable snippets with triggers (e.g. ;;po:meeting) and expand them in-page while you type.
  
  • Multi-provider support — Use your own API keys for Google Gemini or OpenAI, or connect to a local Ollama server for private, on-device optimization.
  
  • Secure and private — API keys stay in your browser (chrome.storage.local). Keys are only used in the background service worker to call your chosen provider. Optional AES-GCM encryption with a passphrase you control.
  
  • Local storage — Settings and libraries stay on your device, not in our cloud. Export text templates from Options (JSON/CSV) if you want your own backup before uninstalling or switching browsers.
  
  • Themes — Light, dark, or system appearance across popup, options, and in-page UI.
  
  GETTING STARTED
  
  1. Install the extension and open Options.
  2. Choose Gemini, OpenAI, or Ollama (Local) and configure your provider.
  3. Select text on any site or use the popup to optimize.
  4. Enter the special prefix to insert custom snippets.
