What you get

What makes Tabbit the best Arc alternative

Agent Mode that does the work

Tell Tabbit what you need—research, booking, data entry—and it runs the task in its own tab group while you keep working elsewhere.

Omnibox with @ context

Type @ to reference open tabs, screenshots, PDFs, or Excel files. No more copy-paste between your browser and an AI chat window.

Skills Plaza

Save your favorite prompts and automations as Skills, or discover community-built ones. Type / to run them instantly.

Vertical tabs + smart workspaces

Keep the sidebar-driven, distraction-free layout you loved in Arc. Tabbit automatically groups tabs into topic-based workspaces.

Switch

Move from Arc without losing the links that matter

1

Save Arc pinned links

Arc cannot directly export Pinned or Favorite tabs. Put them in a Pinned Folder, choose Copy All Links, and save the list.

2

Import supported browser data

Install Tabbit, open Import Bookmarks & Settings, and bring over supported data from Chrome, Edge, or Safari. Re-add the Arc links you saved.

3

Rebuild Spaces deliberately

Create workspaces for active projects, restore essential extensions, verify sign-ins, then test Agent Mode on a low-risk task.
