How to Use This Extension:

Simply open the extension options, paste a free Gemini API key from Google AI Studio, and save. To use, highlight any text on a page to open the inline correction bubble, click the purple sparkle (✨) icon inside any text box to rewrite your draft in-place, or click the toolbar icon to manually polish text. Switch between Proofread, Formal, Casual, and Concise tones to instantly elevate your writing anywhere on the web.

Gemini Grammar Fixer is your intelligent, in-context writing assistant. Powered by Google’s advanced Gemini AI models, this extension lets you proofread and polish your writing directly on any webpage without copying and pasting text back and forth. Whether you are writing an email, posting on social media, or drafting a document, Gemini Grammar Fixer helps you communicate clearly and professionally. ✨ KEY FEATURES: Dynamic Tone Selection Choose the perfect style for your audience. Select from four optimized presets: Proofread: Corrects typos and grammar while maintaining your original voice. Formal: Restructures your text into a polite, business-grade tone. Casual: Makes your message friendly, conversational, and relaxed. Concise: Trims the fluff and gets straight to the point. In-Page Selection Helper Highlight any text on a webpage to instantly display a floating selection bubble. Click your desired tone to replace the highlighted text, or copy the polished result directly to your clipboard. Field Helper Popover Click into any text field or textarea to display a small inline helper icon. Clicking the icon opens a popover menu allowing you to choose your tone and watch your input rewrite itself in real-time. Customized Instructions Fine-tune how the AI processes your writing. Input your own custom system instructions inside the Options page to tailor the default proofreading style. Visual Progress States Enjoy a polished, premium interface with smooth animations, loading indicators, and active glows that pulse around the text input while the AI works. 🔒 PRIVACY & SECURITY: We respect your data. Your Gemini API key and settings are stored 100% locally on your browser. The extension connects directly to Google's API endpoints over an encrypted HTTPS connection. Your text and keys are never sent to any third-party databases. 🚀 QUICK START: 1. Install the extension. 2. Open the Settings (gear icon) and enter your Google Gemini API Key. 3. Start typing in any text box or highlighting webpage text to write with confidence!
