WHY VERTICAL TABS

Why Vertical Tabs Change Everything

Horizontal tab bars were designed for a handful of pages. Modern work demands dozens. Vertical tabs give every page a readable name and a logical home.

Titles you can actually read

Vertical space means full page titles stay visible, so you never confuse two similar tabs again.

Room for dozens of tabs

A sidebar scrolls naturally, while a horizontal bar squishes tabs into unreadable favicons.

Context at a glance

Group work, research, and personal tabs visually. Switch mental modes without losing your place.

TABBIT VERTICAL TABS

Built for Focus, Not Just Fewer Pixels

Tabbit reimagines the vertical sidebar as an intelligent command center. Every feature is designed to reduce friction and multiply focus.

Full Titles, Always Visible

Long titles, doc names, and ticket IDs remain fully readable in the sidebar. No more hovering to guess which tab is which.

AI Smart Groups

Type @ in the omnibox to reference open tabs, then let AI sort them by project, topic, or task—automatically.

One-Click Workspaces

Save and switch between Work, Study, and Life workspaces instantly. Each workspace remembers its tabs, groups, and scroll position.

AGENT MODE × WORKSPACES

Tabs Are Just the Surface. Agent Mode Does the Work.

In Tabbit, the vertical sidebar is not just navigation—it is the visual container for AI Agent tasks. Each agent runs in its own tab group, parallel to your current browsing.

Research in one workspace, work in another

Let Agent Mode compile a report across dozens of sources while you keep writing in your main workspace.

Automate forms across internal tools

Agent Mode fills, submits, and verifies data in a dedicated group without touching your active tabs.

Save any workspace to your knowledge base

Turn a completed research workspace into a searchable collection with one command.

FAQ

Common questions about browsers with vertical tabs

What is a browser with vertical tabs?+

A browser with vertical tabs places open tabs in a sidebar along the left or right edge of the window instead of a horizontal bar at the top. This makes titles readable and makes it easier to manage many tabs at once.

Why should I use vertical tabs instead of horizontal tabs?+

Vertical tabs use screen space more efficiently on wide monitors, keep full page titles visible, and reduce the visual clutter that comes from a crowded horizontal tab bar.

Which browser has the best vertical tabs?+

For pure customization, Vivaldi and Edge are strong. For AI-powered grouping and agentic workflows combined with vertical tabs, Tabbit offers the most complete experience.

Does Tabbit have vertical tabs on macOS and Windows?+

Yes. Tabbit supports vertical tabs on both macOS and Windows, with synced workspaces and smart groups across devices.

Can Tabbit’s AI organize my vertical tabs automatically?+

Yes. Tabbit can analyze your open tabs and group them by project, topic, or task using natural language instructions.

Are vertical tabs better for productivity?+

Most users find vertical tabs more productive when working with 10 or more tabs, because labels stay readable and related tabs can be grouped visually.

How are Tabbit workspaces different from Edge Workspaces?+
