What it costs
What you pay, and the one thing it does not cover.
AI is the one thing not in that number. You bring an OpenRouter key and pay OpenRouter for what you use, with no markup from us. Everything else works without an OpenRouter account.

Questions, answered
Is UtilEngine free?
No. It is $49 once, with every future update included and no subscription. If you use the AI, OpenRouter bills that usage separately at their prices.
Is there a trial?
No trial. You get 14 days to refund, no questions asked.
Who makes UtilEngine?
UnveelWorks, the team behind Hoverify, Vidferry, and SVGLogo.
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, bookmarks, 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.
Which browsers does it support?
Chrome, Brave, Edge, and other Chromium browsers. Firefox support is on the roadmap. Safari is not.
Why write a review of your own product?
Because people search for one and the homepage does not answer it. Read the Chrome Web Store reviews as well, then use the 14-day refund as your trial.
Does the AI work without an OpenRouter account?
No. The AI features need your own OpenRouter key. Everything else works without one.
What happens when I sign out?
Your sessions, bookmarks, snippets, AI commands, and settings leave that browser and come back when you sign in again. Your OpenRouter key is removed too, so you add it again. Chats and snapshots stay on the machine for 30 days, or Erase and Deactivate clears them right away.
Does a session restore tab groups?
Not yet. A session keeps every tab, its order, and which ones were pinned, but not the group it sat in.
Pay once, keep it forever
Sessions, snapshots, AI, and 50+ commands in one launcher. 14 days to change your mind.
