The AI-powered vertical tab manager for a tidier browser
Move your open tabs out of the cramped top bar and into a full-height sidebar where titles and favicons are easy to read.
Let the extension cluster related tabs automatically with AI, so research or project sessions stay grouped without manual sorting.
Nest tabs under parent tabs and drag them between groups to mirror how you actually think about your work.
Built for Chromium-based browsers including Chrome, Brave and Edge, so your setup travels across the browsers you already use.

Your new tab becomes a keyboard-first workspace — tasks, tabs, focus, notes and an AI agent.
One list, four ways to see it. Switch between list, board, table, and calendar with number keys 1–4 without moving a single task.
Save a research trail — a launch, a bug hunt, a reading list — as a tab session and restore the whole set with one click instead of rebuilding bookmarks.
Tasks live in Inbox, Today, Next week, project lists, and personal lists. Details stay folded inside each task until you open it, keeping the list short.
A quiet Pomodoro-style focus timer and a keyboard-first command palette keep deep work moving without reaching for the mouse.
