Lumno is a Manifest V3 browser extension that brings a keyboard-first command palette (like macOS Spotlight, Raycast or the Arc browser command bar) to every web page, and replaces the default new tab with a fast, minimal new tab page. Press Cmd+Shift+K / Ctrl+Shift+K to search open tabs, bookmarks, browsing history and top sites, open a URL, switch tabs, or send a query to Google, YouTube, GitHub, ChatGPT, Gemini, DeepSeek and more. No account required, and your browsing data stays in your browser.
Features
Spotlight-style command bar for any web page
Open a floating command bar on top of the current page to visit URLs, search keywords, switch to an open tab, open browser internal pages such as chrome://settings, or jump into Lumno settings, all without touching the mouse.
Search tabs, bookmarks and history in one place
Results combine bookmarks, browsing history, top sites, browser suggestions and open tabs. Filter by source, prioritize the first result, learn from what you pick, and hide sites with blacklist rules. Chinese titles match by full pinyin, initials or a mix of both (with optional fuzzy pinyin), and a query typed on the wrong keyboard layout (Russian, Ukrainian, Hebrew, Arabic or Korean) still finds what you meant. Choose whether results open in the current tab, to its left or right, or at the end of the tab strip.
Site search and AI search shortcuts
Type a prefix to search inside a site: YouTube, Bilibili, GitHub, Google, Bing, Baidu, Zhihu, Douban, Juejin, Taobao, X, Reddit, Wikipedia and more. Ask AI assistants directly, including ChatGPT, Gemini, Google AI Studio, Copilot, Grok, DeepSeek, Kimi, Doubao, Qianwen, Qwen Chat, Yuanbao and MiniMax. Add your own search templates and aliases.
Aggregate search across multiple engines
Combine 2–10 built-in or custom search sources into one scope and run the same query in several tabs at once. Results can be grouped into a tab group named "Aggregate name: query".
Recent tab switcher
Press Alt+Q to open a keyboard tab switcher and jump between recently used tabs, similar to Alt+Tab for your browser.
AI actions for selected text
Select text on any page to answer, translate, explain, summarize, research or calculate it with your preferred AI provider. Results open in a new tab, optionally in the background.
Customizable new tab page
A clean new tab replacement with a search box, up to 200 shortcuts organized into named groups, recent and most-visited site cards, bookmark grids with cascading folder menus, bookmark paging and custom folder colors. Drag items between shortcuts and bookmarks, pin or hide recent sites, track the latest episode or chapter of a show or novel with progress cards, adjust content width, type /zen for a distraction-free Zen mode, or /present for a presentation mode that hides recent sites and bookmarks and keeps frequent sites, bookmarks and history out of search results. In Firefox, /appearance in the command bar or the new tab search box switches the website appearance pages see between automatic, light and dark. Add any page to your shortcuts from its right-click menu or the toolbar popup; icons without a background of their own sit on a plate tinted from their main color.
Show a clock in one of six fonts, with its own size, opacity, color and an optional 12-hour format, or a daily quote from your own TXT or Markdown collection in the font you choose.
Wallpapers and themes
System, light and dark themes, applied globally or only to the new tab page. Pick built-in wallpapers, the Bing daily wallpaper, curated photos and open-access artwork (limit the random mix to the categories you like), or your own image file or image URL, and save Bing or curated wallpapers you like to your local library. Fine-tune overlay opacity, grain, halftone, dither and ASCII filters, search-box width and the Lumno wordmark.
Give the search bar, cards, menus and dialogs an Acrylic or Liquid glass material that refracts the wallpaper behind it. Over a dark wallpaper the glass turns dark to keep text legible, or it can always match the New Tab theme.
Picture-in-Picture: Web Clip and auto video PiP
- Web Clip PiP: select part of any supported HTTPS page and float it in a Document Picture-in-Picture window for reference or side-by-side comparison.
- Auto video PiP: when you switch away from a playing video, Lumno tries to enter Picture-in-Picture automatically on YouTube, Bilibili, Netflix, Twitch, Vimeo, Prime Video, Disney+, TikTok, Douyin, Youku, Tencent Video and more.
Toolbar popup
Click the Lumno icon in the toolbar to add the current page to your New Tab shortcuts, copy its link, open the command bar, clip the page or start picture-in-picture. Quick settings switch the theme and command bar options, and the footer shows the WebDAV sync status.
Sync with Chrome or your own WebDAV server
Settings sync through Chrome's built-in sync by default. Optional WebDAV sync (Beta) also carries custom shortcut icons and uploaded wallpapers, and works with Nutstore (Jianguoyun) and self-hosted servers. When a server throttles requests, Lumno backs off and retries on its own.
Browser helpers and languages
Shift+click a link to preview it in a small window over the page, then close it or move it to a tab or, where the browser has split views, beside the page in a split view. Restore pinned tabs after a restart, fall back from restricted pages to the new tab page, copy the current page URL with one shortcut, and open extension shortcut or details pages.
The interface comes in 10 languages (English, Simplified Chinese, Traditional Chinese, Japanese, Korean, German, French, Spanish, Brazilian Portuguese and Russian), or follows your browser language. English, Simplified Chinese, Traditional Chinese and Japanese are written and reviewed by people; the rest are AI-translated, and native speakers can fix them from Settings → General → Language → Improve translation.
