Send to Gemini

Send text to Gemini Chat via URL parameters, context menu, and custom prompts

【Detailed Description】 ■ Overview Send to Gemini is a Chrome extension that automatically fills and submits prompts to Google Gemini using URL parameters. ■ Key Features ✓ Auto-fill prompts from URL parameters ✓ JavaScript API for external integration ✓ Auto-submit (can be disabled) ✓ Context menu to send selected text to Gemini ✓ Custom prompts (add, edit, delete from settings) ✓ Combine selected text with custom prompts ✓ Auto-submit can be configured per custom prompt ✓ Multi-language support (English, Japanese, German, Spanish, French, Korean, Portuguese, Chinese) ✓ Large text support via storage ■ How to Use 【Basic Usage】 Simply add the `?prompt=` parameter to the Gemini Chat URL. Example: https://gemini.google.com/app?prompt=Tell me about AI When you access this URL, the prompt "Tell me about AI" will be automatically filled and submitted. 【Disable Auto-Submit】 By default, the send button in Gemini Chat is automatically pressed after the prompt is filled in. To disable the automatic button press, add `autosubmit=false`. Example: https://gemini.google.com/app?prompt=Explain quantum computing&autosubmit=false In this case, the prompt is filled but the send button is not pressed. 【URL Encoding】 Special characters require URL encoding. Example: - Original text: Hello world - Encoded: https://gemini.google.com/app?prompt=Hello%20world Easy to encode in JavaScript: ``` encodeURIComponent("your prompt text") ``` 【JavaScript API Usage】 You can call this extension directly from your web page. ■ Basic Usage: ```javascript // Get your extension ID from chrome://extensions const extensionId = "your-extension-id"; // Send prompt to Gemini chrome.runtime.sendMessage( extensionId, { type: "autofill", prompt: "Tell me about AI", autoSubmit: true // true: auto-press send button / false: don't press }, (response) => { if (chrome.runtime.lastError) { console.error("Failed:", chrome.runtime.lastError.message); } else if (response && response.success) { console.log("Success:", response); } } ); ``` ■ Promise-based version (async/await support): ```javascript function sendToGemini({ prompt, autoSubmit = true }) { return new Promise((resolve, reject) => { chrome.runtime.sendMessage( extensionId, { type: "autofill", prompt, autoSubmit }, (response) => { if (chrome.runtime.lastError) { reject(new Error(chrome.runtime.lastError.message)); } else if (response?.success) { resolve(response); } else { reject(new Error("Request failed")); } } ); }); } // Usage example async function askGemini() { try { await sendToGemini({ prompt: "Explain artificial intelligence", autoSubmit: true }); console.log("Sent to Gemini"); } catch (error) { console.error("Error:", error.message); } } ``` ■ Connection check (ping): ```javascript // Check if the extension is available chrome.runtime.sendMessage( extensionId, { type: "ping" }, (response) => { if (chrome.runtime.lastError) { console.log("Extension not found"); } else { console.log("Connection OK:", response); } } ); ``` ■ Benefits of JavaScript API: - Support for large prompts (thousands of lines of data) - No URL length limitations - Direct integration with web applications - Can be triggered by user actions like clicks ■ Notes: - Extension ID can be found at chrome://extensions with "Developer mode" enabled - Does not work with file:// protocol (requires http:// or https://) - Can be called from any domain due to externally_connectable setting in manifest.json 【Context Menu Integration】 Select text on any webpage, right-click to see "Send to Gemini" in the context menu. ■ Basic Feature: Sends selected text directly to Gemini (without auto-submit). ■ How to Use: 1.
