tabExtend vs Tabox

tabExtend is a visual tab manager that adds notes, images, and reminders inside the browser. Users can save, close, and reopen groups of tabs with drag-and-drop or right-click actions. It also supports to-dos, colored notes, and reminders for sites and items. Workspaces and categories can be shared privately or publicly, with colleagues invited to collaborate in real time. Workspaces sync to the cloud for use across devices; tabExtend says its stored data is end-to-end encrypted and backed up twice a day. Search helps locate saved items, and groups can be generated from bookmarks and most-visited sites. The extension is available for Chrome, Brave, and Edge, with native apps for Android and iPhone/iPad. The free plan includes basic features and up to 30 saves, with unlimited time and no account required. Pro is $8 a month; Team is $21 a month for three seats, with additional seats at $7 each. The extension can replace the new-tab page and read browsing history; downloads, most-visited URLs, and bookmarks are optional permissions.

Tabox is a browser extension for saving open tabs and tab groups as named collections, then organizing and reopening them. It is available for Chrome, Firefox, and Edge. Collections can be placed in folders, reordered, color-coded, and displayed in list or grid layouts; saved tab groups retain their names, colors, titles, URLs, and order. Optional Google Drive sync stores collections in a hidden application data folder in the user's Drive. Optional AI actions can group tabs, remove duplicates, rename collections, and arrange folders. When an action runs, relevant titles and URLs are sent to Tabox's API and forwarded to OpenRouter; Tabox says it does not store prompts or responses. Shared folders support collaboration, and collection links let recipients access shared content. Local collections stay on-device by default, and users can export collection and folder data as text files, including backups. The free plan includes core collections, restore, folders, and Google Drive sync. Pro lists AI tools, shared folders, collection links, and an AI assistant, with a 7-day free trial; its price is not shown.
