FEATURES
Why we built a Vertical Tabs Manager
Heavy tab users discovered through Arc's sidebar-first workflow that once dozens of tabs are open, horizontal tabs become visual noise. Side Space is built for this exact problem.
Readable Vertical Scanning
A sidebar is better for tab-heavy work because full tab titles stay readable.
Spaces over Tab Clutter
Tabs should become workspaces instead of disposable clutter. That is what Spaces are for.
Effortless AI Organization
Organization should feel effortless, and AI Grouping helps reduce manual sorting.
BENEFITS
What you get with Side Space Vertical Tabs
2) Spaces: keep projects separated
Spaces let you treat sets of tabs like work contexts.
Examples:
- -"Client campaign" space
- -"Study / course" space
- -"Personal / shopping" space
Separate spaces keep contexts clean and focused.
3) Sync across devices (so your work follows you)
Pick up where you left off. Keep your spaces consistent across machines.
- -Sync your spaces and tabs across all your Chrome browsers
- -Pick up work where you left off—on any machine
- -Works with your Google account
Keep your setup consistent across machines.
4) AI Grouping: auto-organize tab chaos
When you open a bunch of pages from search results, docs, or competitor research, AI Grouping helps cluster related tabs-so you can move from "collecting" to "executing."
Common flows
- -Research a topic -> AI groups sources
- -Compare products -> AI groups competitors vs reviews vs docs
- -Prepare a brief -> groups become sections / references
Auto-grouping helps you shift from collecting to execution.
