Tab chaos
Vertical tabs + smart workspaces

Focus-first browser · Parallel Agent lanes
A Productivity Browser for Focused Work
Your attention stays on one task. Tabbit's AI Agent runs in an isolated tag group—researching, summarizing, and executing while you stay in deep focus. No tab roulette, no serial waiting.
Your focus lane
Stay inside the draft
- Full-screen reading lane with zero tab clutter

Agent laneResearch while you write
- Agent scans sources and pulls quotes into a brief
- @-reference open tabs as citation context
- Summaries land in a separate tag group
Distraction killers
Four focus killers—and how Tabbit fixes them
Context switching
Isolated Agent tag groups
Research, forms, and summaries run in a separate lane. You read; Agent executes. No bouncing between tabs to check progress.
AI in your face
Parallel lanes, not pop-up chat
Classic AI sidebars steal attention. Tabbit Agents work out of sight in their own group—results surface when you need them.
Lost deep-work flow
90-minute session timeline
Plan a deep-work block: one focus lane, one Agent lane, one outcome. Tabbit keeps both threads visible without overlap.

Definition
What is a focused work browser?
A focused work browser is built for deep work: long stretches of attention on one primary task, with tools that reduce tab clutter, context switching, and notification noise—not add more of it.
Tabbit is a productivity browser for focused work that splits your attention into two lanes: a clean focus thread for reading and writing, and an isolated Agent thread that researches, summarizes, and executes in the background. You stay in flow; the browser handles the busywork.

Yes. Tabbit offers full feature parity on macOS and Windows: parallel Agent lanes, vertical tabs, Skills, and one-click import from Chrome or Edge.
How is Tabbit different from Arc for focused work?+
Arc excels at Spaces and visual organization on Mac. Tabbit adds parallel Agent execution in isolated tag groups—so research and forms run while you read, on both Mac and Windows.
How does Tabbit compare to Zen Browser for focus?+
Zen Browser minimizes UI chrome for calm browsing. Tabbit goes further with AI-native dual lanes: your focus tab stays untouched while Agent handles multi-step tasks in a separate group.
How does Agent isolation protect my focus?+
Agent Mode runs in its own tag group—never overlapping your focus lane. Progress, new tabs, and summaries stay in the Agent lane until you choose to review them.
Can I import from Chrome when switching to Tabbit?+
Yes. Tabbit imports bookmarks, history, passwords, and extensions from Chrome, Edge, or Safari in minutes so you start focused work without rebuilding your setup.
Does Tabbit support deep work sessions?+
Yes. Use workspaces to pin your focus tab, queue Agent tasks at session start, and archive results to collections at the end—designed for 60–90 minute deep-work blocks.
