Caret-anchored CapsLock & status visualization and Space Shift home-row navigation.
Reduces eye travel and hand reaches so you can stay in unbroken Flow.
Why does typing feel exhausting? The friction is not human error—it is an inherited flaw in PC design.
Glancing down at the far corner of your taskbar just to check your input mode breaks cognitive flow. With multiple windows open, guessing which window has focus leads to frustrating mistypes.
Caret-First: State is anchored right next to your caret, reducing eye movement to the taskbar.
Reaching for arrow keys, Enter, and Backspace breaks your typing posture dozens of times a minute. Constantly twisting your pinky to hold Shift or Ctrl adds physical strain to wrists and fingers.
Keyboard-First: Thumb Space unlocks Layer 2, placing navigation keys at your fingertips.
Intrusive assistant balloons and bouncing tooltips cover the very text you are writing. When you need deep concentration, unnecessary animations create friction.
Smart UI: Fades the moment you type. Quiet design that stays out of your way.

Save your personal configurations and make fjFlow your permanent daily utility
Because fjFlow handles daily keyboard input, transparent offline operation and predictable behavior come first.
Never. No external network communication is implemented (Zero Telemetry). Keystroke logic is evaluated in volatile local memory and is never logged to disk.
Only in local JSON files on your PC. It does not modify the Windows Registry. You can inspect, back up, or delete the JSON file at any time without leaving residual traces.
No. fjFlow operates 100% offline. It runs in air-gapped corporate environments and during network outages without any change in behavior.
Only for elevated windows. By default, it runs with standard user rights. "Run as Administrator" is only needed if you want hooks to work inside elevated (UAC) windows.
