IsoKey: The Hardware-Agnostic
Command Engine.
Intelligent hardware signal isolation built for Windows. Use any secondary keyboard, numpad, or custom controller as a dedicated macro deck without duplicating primary keypresses.
What Makes IsoKey Unique?
Traditional remappers duplicate keypresses across all connected keyboards. IsoKey operates below standard user-mode hooks, isolating hardware device IDs at the driver layer so your 2nd keyboard acts as an independent, fully-customizable command surface.
Complete Productivity Engine Matrix
Nine high-performance capabilities engineered across hardware isolation, real-time desktop overlays, and multi-monitor workspace snapping.
Hardware Isolation & Touch Decks
Dedicated command surfaces, hardware device binding, and custom layout builders.
Secondary Keyboard Isolation
Isolate secondary USB or Bluetooth keyboards at the kernel driver layer so every key becomes an independent macro trigger without interfering with standard typing.
WiFi Mobile Touch Deck
Turn your mobile phone, tablet, or secondary touch device over local WiFi into a dynamic touch deck to trigger actions, OBS scenes, and webhooks wirelessly.
Visual Keyboard Designer
Build, record, and map key positions across 5 default presets (Full Size, TKL, 75%, 60%, Numpad) with real-time Virtual Key (VK) recording.
Desktop Overlays & Workflow Automation
Transparent HUD controls, natural speed text automation, and zero-latency triggers.
Live Overlays & Web Widgets
Display floating HUD toolbars, cursor-attached radial dials, live CPU/GPU telemetry monitors, and custom open-source HTML5/JS desktop widgets.
Natural Typing Automation
Automate text expansion, code snippet pasting, and repetitive typing routines with customizable micro-delays for realistic human speed.
Instant System Shortcuts
Execute 24+ built-in actions instantly—from controlling OBS Studio streams and system volume to firing REST webhooks with zero input lag.
Precision Workspace & Layout Control
Multi-monitor physical pinning, grid region snapping, and visual drag-and-drop setup.
Smart Physical Monitor Lock
Pin application windows permanently to specific physical monitors so your desktop layout stays rock-solid even across computer reboots.
Point & Drag Region Snapping
Snap windows instantly into multi-monitor grid zones with visual point-and-drag precision or single-key workspace recall shortcuts.
Seamless Drag & Drop Setup
Zero complex coding required. Configure custom layouts, shortcuts, overlays, and action rules with an intuitive visual editor.
