Please note: This is a paid extension, you can buy it from https://utilengine.com UtilEngine is the launcher your browser is missing. It brings AI chat, saved sessions, tab search, and everyday tools to every page you visit. Press your shortcut anywhere and start typing. Ask a question, bring back yesterday's work, find that one tab, or work out a sum without leaving what you're reading. ⚡ One shortcut, every tool - Open it with your own keyboard shortcut (Alt+Z by default, change it anytime). - Highlight something first and the tools that fit it come up at the top, already filled in. - Favorites: pin the commands you use most so they show before you type. - Keywords: give any built-in feature a short name you pick, and that name puts it at the top. - Fallbacks: choose where your words go when nothing matches, and in what order. - Quick slots: give up to five commands a shortcut of their own. - Type ue and a space in the address bar to run a command from there. - All Tools: browse everything UtilEngine can do in one list, with what to type for each. - Hide it mid-task and it parks as a small pill at the top of the page. Bring it back exactly where you left it. 🔎 Find anything you've opened - Tabs: search every open tab across windows by title or address. Type t and a word. Switch to it or copy its link. - History: find a page you visited. Type h and a word, or paste a URL. - Bookmarks: browse your browser's bookmarks folder by folder, or search them. Type bb. - Downloads: find a past download and open it again in one click. - Extensions: turn installed extensions on or off, or remove one, right from the launcher. 🔗 Quicklinks and snippets - Quicklinks: save sites with a placeholder for a search term, then open one by name with the term right after it. Highlight a word and it's filled in for you. - Snippets: save text you type often and insert it into any field by name. Add blanks to fill in and mark where the cursor should land. - Sort both into categories, and export them to a file or import them back. 🧮 Calculator Type math straight into the search bar and mix in units and money: 5 km + 300 m, 180 F to C, or 100 USD to EUR with live rates for 35 currencies. It understands 1,250, $125k, and 12 crore INR, and keeps a history. ✨ Bring your own AI - Full chat with any model, wherever you are. - It sees what you see: the page you're on, the text you selected, or what you just copied. Ask about an article, fix a paragraph, or draft a reply. - It can search your tabs, history, downloads, quicklinks, and bookmarks, do math, convert currencies, and search the web. Turn any of these off in settings. - Ask AI: type a question and press Tab for a quick answer without opening a chat. Your last 20 answers are kept, ready to copy or continue. - Built-in actions fix grammar, summarize, simplify, translate, or rewrite whatever you've highlighted. Write your own reusable prompts and pick a model for each one. - One OpenRouter key opens 89 models from the major labs, billed by each provider with no markup from us. Or connect a model server running on your own computer. - Every reply shows its token count, so you always know what a conversation costs. - Rather not use it at all? One switch turns it off. 🪟 Never lose a window - Save any window as a session. Close it, reopen it tomorrow, or on another computer. - Pick exactly which tabs go in, or save the whole window at once. - See every tab across all windows on one board. Jump to, pin, sleep, or close any of them, or select several and open them together. - Restoring brings back the window and tab you had in front. Anything your browser refuses to open is skipped, and you're told what. - An automatic snapshot every hour. Change the interval anytime, or turn it off. - 14 days of history, up to 500 snapshots. Pull back exactly what you had open on Tuesday morning. - After a crash, the last snapshot is one command away. Closing a window saves a final one. - A dedicated session manager to organize everything you've saved. 🧰 More everyday tools Small utilities for day-to-day work are built in. Format JSON and convert it to other data formats, or decode a web token. Compare two versions of a text, find and replace with patterns, sort lines or remove repeats, and clean up text you pasted. Preview and tidy HTML, encode and decode links and Base64, generate hashes and unique IDs, and convert images. Text tools can replace your selection with the result. 🔄 One profile, every browser - Your sessions, quicklinks, snippets, AI commands, and settings follow you to every browser you sign in on. - Your account works on up to 10 devices at the same time. Manage them from your dashboard. 🔒 Private by design - No analytics, no telemetry, no tracking. Page content and browsing history never reach our servers. - Chat requests go straight from your browser to OpenRouter on your own key, or to your own local server. Your conversations, and any page text, selection, or copied text you share, never touch our servers. - We store your account details, your purchase record, and the browsers you've signed in on. If you use sync, your saved sessions, quicklinks, snippets, AI commands, and settings are stored so they can follow you across devices. Your API key and local server address are never synced and stay on each device. - UtilEngine uses Shadow DOM isolation, so it never interferes with page styles. On restricted pages like chrome:// URLs, it opens in a standalone tab. 💡 Bug Report and Suggestions To report a bug or for a feature request, you can send an e-mail to hello@utilengine.com.
