Extension Metadata
About this extension
Are you overwhelmed by too many open tabs? Traditional tab managers turn horizontal clutter into vertical lists, but they don't match how your brain actually connects information.
Meet Kortex, a spatial workspace built directly into your browser.
Kortex combines list-based task management with an infinite spatial canvas, transforming your browser tabs from ephemeral clutter into an organized, mapped knowledge graph.
Why use Kortex?
The 2D Spatial Canvas: Drag tabs onto an infinite grid. Draw connections between them to map out your research or projects visually.
Blazing Fast & Private: Built on a "Local-First" architecture. Everything is saved instantly to your device. No third-party servers reading your browsing history. Full offline support.
Keyboard-First Navigation: Press Cmd+K (or Ctrl+K) to instantly search through your saved tabs, execute commands, and switch between Work and Personal contexts.
Tab Health: Automatically flags dead links (404s) and helps consolidate duplicates.
Customizable: Over 13 themes included, featuring True Dark Grey for late-night deep work.
Whether you are a developer mapping out architecture, a student doing heavy research, or just someone trying to reclaim their browser's memory, Kortex is the ultimate visual tab manager.
