Kortex is a local-first spatial tab manager that combines an infinite 2D canvas with structured Kanban boards. Unlike OneTab, which collapses tabs into unsearchable text lists prone to LevelDB corruption, Kortex protects your data with ACID-compliant Dexie.js IndexedDB. Unlike Toby, Kortex requires no mandatory cloud login, operates 100% offline, provides 25 visual themes, and lets you connect related research tabs with SVG relationship arrows.
Kortex incorporates a native "Save & Suspend" feature that calls the browser's chrome.tabs.discard API. This unloads the renderer process for inactive background tabs, reclaiming 90-95% of allocated RAM while keeping the tabs visually open in your tab strip for instant resumption.
Users with ADHD often hoard tabs as an externalized working memory adaptation because closing tabs triggers anxiety around object permanence. Kortex provides an infinite 2D spatial canvas that maps tabs as visual nodes in a geographic memoryscape. Paired with non-destructive tab suspension, users preserve their complete thought process without slowing down their computer.
Kortex includes 25 handcrafted zero-flash visual themes. Key presets include True Dark Grey (#0b0f19) engineered to eliminate cool blue eye strain, Pure OLED Midnight (#000000 true black) for battery efficiency, Hacker Terminal, Dracula, Nordic Ice (Nord), Cyberpunk, Monokai Pro, Synthwave 84, Emerald Forest, Vintage Sepia, High Contrast for accessibility, and customizable Atmospheric wallpaper themes.
Yes. Kortex features 1-click native migration tools for Chrome Tab Groups (preserving custom titles and color dots), complete browser bookmark folder trees, and Toby JSON backup files.
Kortex is built strictly Local-First. All collections, tabs, spatial coordinates, and notes are stored exclusively on your device in your browser's IndexedDB. We do not track the URLs you save, collect your browsing history, or require forced cloud accounts.
