TabAtrium: Bookmark Manager on New Tab

TabAtrium is a fast bookmark manager and custom new tab start page. It replaces your default new tab page with an organized bookmark board, laid out in custom groups with tag filtering and instant search. Built for power users, researchers, and anyone who wants their saved links one click away instead of buried three folders deep. Use TabAtrium as a clean, minimal speed dial: launch your favorite websites instantly from your new tab without heavy thumbnails, widgets, or tracking feeds slowing down your browser. THE PROBLEM IT SOLVES A bookmark inside a traditional folder tree is easy to save and hard to find. Native browser bookmark bars hide your links, forcing you to search the web for the same page again. Folders also force each link into a single rigid bucket, even when a URL belongs to multiple projects at once. TabAtrium organizes your entire link collection into clear, column-based groups on the page you open most, letting every bookmark carry multiple tags for effortless retrieval. KEY FEATURES 📌 Minimal speed dial and custom start page • Instant website shortcuts: replaces the blank new tab page with a customizable bookmark dashboard. • Compact, group-based layout: access links in organized columns rather than bloated, slow-loading thumbnails. • Distraction-free productivity: light and dark modes with customizable backgrounds. Zero ads, zero news feeds, zero unwanted widgets. • Instant offline access: caches a local copy in your browser, so your new tab opens with zero latency even without an internet connection. 🔖 Smart bookmark organizer and tagging • Column groups and drag-and-drop: organize bookmarks side by side in visual columns. Drag groups to reorder your board, or drag links between groups. • Customizable group appearance: set a small, medium, or large font size for each group, so the links you use most stand out. • Flexible tag-based filtering: replace deep, nested folders with flexible tags. Click any tag to filter your board instantly, or isolate a single group. • Type-to-search retrieval: rapid full-text search scans titles, URLs, and tags as you type. • Address bar search: type ta and a space in the address bar to search your bookmarks without opening a new tab. Press Enter to open the top match. • One-click toolbar capture: save the current page to any group from the browser toolbar popup. Page titles and site favicons are detected automatically. • Quick context menu: right-click any link to edit, copy, duplicate, open in a new background window, or delete. 🔄 Import, export, and cross-browser sync • Native browser import: import bookmarks directly from Chrome, Firefox, Edge, or Brave. Select specific folders; top folders become groups and subfolders become tags. Your original browser bookmarks remain completely untouched. • HTML backup and portability: import or export a bookmarks HTML file that any desktop browser can read. • Cross-browser sync: sign in with Google or an emailed link to sync your groups, tags, and link order across Chrome and Firefox. HOW TO USE 1. Install TabAtrium and open a new tab. Sign in with Google or your email address to sync across devices. 2. Import your existing bookmarks from your browser, upload an exported HTML file, or use ＋ Group to build your board by hand. 3. Filter links by clicking tags, search titles as you type, and use the toolbar icon to save new pages in one click. PRIVACY, PERMISSIONS, AND DATA OWNERSHIP TabAtrium is built on a local-first, privacy-respecting architecture. We store only the bookmarks you explicitly save or import (title, URL, group, tags, and board position) and your account identifier. • Zero tracking: we do not read your browsing history, monitor your active tabs, or log the links you visit. There are no advertising trackers or analytics SDKs. • Data portability: you can export your full bookmark library to a standard HTML file, or delete your account, at any time. What each permission is for: • Storage: saves your board layout and theme preferences locally in your browser. • ActiveTab: lets the toolbar popup read the active page title and URL, only when you click the extension button. • Website access: fetches page titles and site favicons for the links you save. • Bookmarks (optional): requested only if you use "Import from browser"; it reads your bookmarks once and never alters them.
