Less chrome, fewer competing surfaces, and a layout that stays out of the way.

Power-user toolbox

Why Tabbit
Tabbit keeps the spatial habits Arc trained you to expect: vertical rhythm, structured workspaces, and a calm surface. But it upgrades the intelligence layer to agents that can read pages, fill forms, and deliver results—only after you approve each sensitive step.
You are not locked to one AI vendor. Tabbit gives you multi-model access and a Skills marketplace that turns recurring research, filing, and tab workflows into reusable playbooks.
What you get
Vertical sidebar, smart grouping, and project-based workspaces keep hundreds of tabs scannable without collapse.
Ask the browser to research, compare, or file. It runs in its own tab group and pauses for your approval before acting on logged-in sites.
Save prompts and scripts as reusable Skills. Switch between top models without leaving your workflow.
Switching
Bookmarks, history, passwords, cookies, and extensions come over from Chrome, Edge, Safari, or Arc in one click.
Do not clone every tab. Create two project spaces first—quality beats volume when rebuilding muscle memory.
A research brief, expense report, or ticket triage. Measure friction, not just how pretty the UI looks.
Decide which sites agents can touch and when they must pause. Governance is what makes agentic browsing usable.
