Lumen Agent — browser extension

The in-browser half of Lumen's agentic mode. Lumen can act in your own logged-in browser — like Perplexity Comet — or run server-side with no install at all.

No install

Server mode

Lumen drives a secure headless browser on its own servers. Works for everyone, instantly. Best for public web research and extraction.

Your browser

Extension mode

Lumen acts in your Chrome, using your logged-in sessions and cookies. Best for tasks on sites you're already signed into.

Install — Chrome / Edge / Brave

Download for Chromium (.zip)
  1. Unzip the downloaded file to a folder you'll keep.
  2. Open chrome://extensions in your browser.
  3. Turn on Developer mode (top-right toggle).
  4. Click Load unpacked and select the unzipped folder.
  5. Pin the Lumen Agent icon, click it, and press Enable.
  6. Come back to Lumen and use Agent mode with mode: ext.

Install — Firefox

Download for Firefox (.zip)
  1. Open about:debugging#/runtime/this-firefox.
  2. Click Load Temporary Add-on and pick the manifest.json from the unzipped folder.
  3. For a permanent install the same package can be signed at addons.mozilla.org.

Install — Safari

Download for Safari (.zip)

Safari extensions are wrapped in an app. The download is a complete WebExtension bundle; on a Mac with Xcode run xcrun safari-web-extension-converter on the unzipped folder (see SAFARI_README.txt inside) to build the app.

No install? Server mode already works.

Lumen's headless browser path (mode: server) drives a real browser on our side — full navigate/click/fill/extract — in every browser, with zero install. The extension is only needed when you want Lumen to act inside your own logged-in browser sessions.

Privacy: the extension only talks to ask.eliteaiempire.com and acts only while you've enabled it and a Lumen agent run is active. Disable any time from the popup.

What the agent can do in-browser

navigate to a page · click links and buttons · fill form fields · press keys · extract readable text · list interactive elements. The same action vocabulary works in server mode, so your agent prompts are identical either way.
