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

【Detailed Description】

■ Overview Send to Claude is a Chrome extension that automatically fills and submits prompts to Claude using URL parameters.

■ Key Features ✓ Auto-fill prompts from URL parameters ✓ JavaScript API for external integration ✓ Context menu to send selected text to Claude ✓ Large prompt support

■ How to Use

【Basic Usage】 Simply add the ?prompt= parameter to the Claude URL.

Example: https://claude.ai/new?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】 To fill the prompt without automatically submitting it, add autosubmit=false.

Example: https://claude.ai/new?prompt=Explain quantum computing&autosubmit=false

In this case, the prompt is filled but the send button is not pressed.

【JavaScript API Usage】 You can call this extension directly from your web page.

■ Basic Usage:

// extension ID
const extensionId = "gcbomhdkipopmgjemnonhhmmfggffnno";

// Send prompt to Claude
chrome.runtime.sendMessage(
extensionId,
{
type: "autofill",
prompt: "Tell me about AI",
autoSubmit: true // Set false to fill without sending
},
(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):

function sendToClaude({ 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 askClaude() {
try {
await sendToClaude({
prompt: "Explain artificial intelligence",
autoSubmit: true
});
console.log("Sent to Claude");
} catch (error) {
console.error("Error:", error.message);
}
}

■ Connection check (ping):

// 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);
}
}
);
