The launcher your browser is missing. It brings AI chat, saved sessions, tab search, and everyday tools to every page you visit. Please note: This is a paid extension, you can buy it from https://tryhoverify.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. Open the launcher on any page and start typing. Chat with AI, save your windows as sessions, and search your tabs and history without leaving the page. ⚡ The launcher - Every tool, any page, behind your own keyboard shortcut (Alt+Z by default, change it anytime). - Tabs: search any open tab across windows, by title or URL. Type t and a keyword. - History: find any visited page. Type h and a keyword, or paste a URL. - Downloads: find any past download. Open it again in one click. - Bookmarks: save sites with placeholders. Launch them by name from any page. - Snippets: save text you type often and insert it into any field by name. Add arguments the launcher asks for, and mark where the cursor should land. - Calculator: type math in the search bar. Functions, constants, history, all inline. - Currency converter: 35 currencies, live rates. Type 100 USD to EUR in the search bar. - Hide the launcher mid-task and it parks as a small pill at the top of the page. Bring it back exactly where you left it. ✨ Bring your own AI - Full chat with any model, on any tab. - AI that sees what you see: it can read the page you're on, the text you selected, or what you just copied. Ask about this article, fix this paragraph, or reply to that email. - AI that uses your browser: it can search your open tabs, history, downloads, and bookmarks, do math, convert currencies, and search the web. Turn any of these off in settings. - Ask AI: type a question, hit Tab, skip the chat UI. - AI commands: reusable prompts with dynamic variables, and a different model for each one. - One OpenRouter key for 75 models from the major AI labs. Pay providers directly, with no markup from us. 🪟 Never lose a window - Save any window as a session. Close it, reopen it tomorrow, or on another machine. - Pick exactly which tabs go into a session, or save the whole window in one go. - See every tab across all windows in one board, and pin, sleep, or close them from there. - Automatic snapshots: every hour, all windows and tabs. Change the interval anytime, or turn it off. - 14 days of history, up to 500 snapshots. Pull back Tuesday morning's exact tabs. - After a crash, the last snapshot is one command away. Closing a window writes a final one. - A dedicated session manager to organize saved windows, tabs, and snapshots. 🧰 More everyday tools Small utilities for day-to-day work are built in: format JSON and convert it between common data formats, transform and compare text, preview and clean up HTML, encode and decode URLs and Base64 strings, and convert images between common formats. 🔄 One profile, every browser - Your sessions, bookmarks, snippets, and AI commands follow you. Chrome, Brave, Edge, any device. - 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. - AI runs on your own OpenRouter key, straight from your browser to OpenRouter. Your conversations, and any page text, selection, or copied text you share with the AI, 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, bookmarks, snippets, and AI commands are stored so they can follow you across devices. - UtilEngine uses Shadow DOM isolation, so it never interferes with page styles. On restricted pages like chrome:// URLs, it opens in a standalone tab.
