Questions, answered
Do you offer a trial version?
No trial, but you get 14 days to refund. No questions asked.
How do I get started after buying?
Install it from the Chrome Web Store, click Sign in, and pick Google or a one-time code sent to your purchase email. The extension registers the device on its own.
Can I use UtilEngine on my work and home computers?
Yes. Your account works on up to 10 devices at the same time. Manage them from the dashboard.
What browsers are supported by UtilEngine?
UtilEngine works on Chrome, Brave, Edge, and other Chromium browsers. Firefox support is on the roadmap.
Do you collect my data?
Only what your account needs. You sign in once with Google or your purchase email, and we store your account details, your purchase record, and the browsers you have signed in on. If you use sync, your saved sessions, quicklinks, snippets, AI commands, and settings are stored so they can follow you. Your OpenRouter key is never synced. Your browsing history and page content never reach our servers.
What can the AI do?
Ask a question inline, summarize or rewrite a selection, ask about the page, and write your own commands. Chat can read the page you are on and search your tabs and downloads, and your history once you switch it on. Any of 85 models, a different one per command if you like, or a model on your own computer.
Do I need to pay for AI features separately?
Only for what you use. Add a free OpenRouter API key and pay OpenRouter directly, with no markup from us. Or connect a model running on your own computer, like Ollama or LM Studio.
Does it work on all websites?
Yes. UtilEngine uses Shadow DOM isolation, so it never interferes with page styles. On restricted pages like chrome:// URLs, it opens in a standalone tab.

Every feature above has its own page. Start with the one you came for.
