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.

Turn your browser's new tab into a tab, notes and AI workspace
Manage tabs and tab groups, drag and drop to save or close them, discard tabs to free resources, and organise everything in grid, column, list and tree views.
Create and edit documents, take notes, manage to-dos, store code snippets and use Markdown with syntax highlighting directly in the new tab.
Assemble custom-prompted AI helpers, chat with AI, use Vision AI for image recognition and choose among ChatGPT 3.5, 4.0 and Turbo models.
Create and subscribe to RSS feeds, and follow YouTube and Reddit feeds, all from inside your new tab.
