Frequently Asked Questions
You have questions, we have answers!
Do you offer a trial version?
No trial, but you get 14 days to refund. No questions asked.
Can I activate my license key on my work and home computer?
Yes. One key works in 3 browsers at the same time. Manage activations from your 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?
No. We verify your license once on activation, and store your name and email. Nothing else leaves your browser. Nothing is shared with anyone.
What AI models are supported?
43 models from OpenAI, Anthropic, Google, and MoonshotAI. Pick a different model for each AI command.
Do I need to pay for AI features separately?
AI features need a free OpenRouter API key. You pay OpenRouter directly for usage. We take no markup.
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.
