Ask anything, on any page
Type a question in the launcher and hit Tab. The answer comes back inline, no chat window, no new tab. Built for the hundred small questions a day. A regex, a date, a word you forgot. Closed one too soon? Ask AI History keeps your last 20.
Your selection, handled
Select text, run a command, and the result comes back right on the page, ready to copy.
Six built in
Summarize, fix, translate, rewrite, simplify, or ask about the page.
Write your own
A name, a prompt, a model, a few keywords. Drop arguments into the prompt and the launcher fills them from the page when you run it.
A chat that knows your browser
Chat when you want a back-and-forth. It can read the page you are on, search your browser, and search the web. Every call shows up in the chat.
The page sits closest, your browser next, everything beyond it on the outside. Every tool is read-only, and every one has a switch.
Control what the AI can read
The AI has 12 tools and each one has a switch. Here are five of them, from your selection and open tabs to the web and this page. Off means the AI can't call it.
An off tool is left out of every request.
One key. Any model.
Every command and chat can use a different model, 89 of them behind one OpenRouter key. Most AI extensions resell that access as a subscription. UtilEngine doesn't. You pay the provider directly, at their prices, and the extension is a one-time purchase.
How bring-your-own-key worksOr run it on your own computer
Point UtilEngine at a model server on your machine, like Ollama or LM Studio, and skip the key. Chat, Ask AI, and your commands run on that model, so your prompts and the page text stay with you.
The server address stays on this device and never syncs. Web search needs OpenRouter.
AI questions
What can the AI do, beyond chat?
Run commands on your selection or the page (summarize, translate, rewrite, fix grammar, ask about the page), answer a question inline without a chat window, and read the page or your selection while it answers, along with searching your tabs, downloads, quicklinks, and bookmarks. History and copied text join in once you switch them on. You can also write your own commands.
Which AI models can I use?
89 models from OpenAI, Anthropic, Google, Meta, xAI, MoonshotAI, and Z.AI, all through one OpenRouter key that stays in this browser. Or connect a model server on your own computer and use the models you run there.
Do I pay for AI usage separately?
Yes, and that is the point. You pay OpenRouter directly for what you use, at provider prices. UtilEngine takes no markup and sells no AI subscription. A model on your own computer costs nothing per token.
Where is my API key stored?
In your browser's extension storage. You add it in AI Settings, a window of its own rather than a web page, and it never syncs to our servers. A local server's address and key stay on the device the same way.
Can I use Ollama or LM Studio?
Yes. In AI Settings, set Provider to Local server, type the server's address, and press Connect. It works with Ollama, LM Studio, llama.cpp, and other OpenAI-compatible servers. Chat, Ask AI, and your commands all run on it. Web search needs OpenRouter.
Can I get back an answer I closed?
Yes. Ask AI History keeps your last 20 Ask AI and AI command answers. Open one to copy it, paste it into the field you are in, or carry on as a chat.
Can I turn the AI off?
Yes. Switch off Enable AI in AI Settings and every AI command leaves the launcher, including the ones you wrote. The choice follows you to the other browsers you sign in on.
How do custom commands work?
Give a command a name, a prompt, a model, and a few keywords. Prompts take arguments like {selection}, {copied}, {tab-text}, or {url}, with || for fallbacks and up to three arguments of your own. It then shows up in the launcher like any other command, and text you type after its name fills your first argument.
Can different commands use different models?
Yes. Every AI command has its own model setting. Use a fast model for grammar fixes and a stronger one for analysis.
Does it work on any website?
Yes. The launcher opens on any page. Commands can read your selection or the page text when you ask them to.
Can the AI search the web or my tabs?
Yes. While it answers, it can search the web, your open tabs, downloads, quicklinks, and bookmarks, read the page you are on or your selection, and do math and currency conversion. History and copied text are there too once you switch them on in AI Settings. Every tool call is shown in the chat, so you always see what it looked at.
How does the AI read the page?
Two ways. Say "this page" or "this article" in chat or Ask AI and the AI reads it through a tool, which shows up as a chip in the answer. Or type / in chat to attach the page, your selection, or copied text to a message yourself. Either way the text is captured when you send and only enters the conversation when it is used.
Can I turn tools off?
Yes, one switch per tool in AI Settings. A tool that is off is left out of every request, so the AI can't call it. Text you attach with /, or an AI command whose prompt asks for the selection, copied text or page text, is still sent, because you asked for it.
AI in your browser, one keystroke away
Ask, rewrite, summarize, or write your own commands, in a launcher with 60+ built in.
