About Gemini URL Prompt - Auto Prefill

Miss the ability to pass prompts directly via URL, just like you do with ChatGPT? Gemini currently does not natively support URL parameter prefilling. This lightweight extension bridges the gap, allowing you to pass your prompts directly into the Gemini input box using a simple URL query. It is the perfect companion for power users who rely on productivity launchers (like Alfred, Raycast, PowerToys Run) or want to create bookmarks for specific AI tasks. 🚀 Key Features: • URL Parameter Support: Works with ?prompt= or ?q= parameters. • Auto-Detection: Automatically finds the input box even on slow connections. • Native Input Simulation: Uses advanced DOM event simulation to ensure Gemini's framework recognizes the text input without resetting it. • Privacy First: Runs entirely on your device. No data collection, tracking, or external analytics. 💡 Usage Examples: Basic Usage: https://www.google.com/search?q=https://gemini.google.com/app%3Fprompt%3DWrite a summary of this article Alfred / Raycast Integration: Create a custom Web Search with the URL: https://gemini.google.com/app?prompt={query} Now you can simply launch your tool, type "gemini Explain quantum physics", and watch it open ready to go! Custom Bookmarks: Save your most used, complex prompts as browser bookmarks for one-click access. 🔒 Privacy Policy: This extension operates solely on gemini.google.com. Its only function is to read the URL parameter and inject text into the page's input field. We do not collect, store, or transmit any user data or chat history.
