$ ./blindspot --info

BlindSpot.

Draw redaction boxes on top of any window. They stick to that window and follow it as you move, resize, or snap. Made for screen sharing without the panic.

[01] how it works // three steps
  1. Press Ctrl + Win + R to enter draw mode.
  2. Click the window you want to cover, then drag a box over the part you want hidden.
  3. Press Esc. The box is locked to that window. Move it, resize it, snap it. The redaction follows.

To edit later: press the hotkey again, click a box. Drag to move, drag corners to resize, click the center X to remove it. To clear every box at once: Ctrl + Win + Shift + R.

[02] features // v1, windows

Window-anchored

Boxes attach to a specific window and ride along when it moves, resizes, snaps, or minimizes.

Smart corner anchoring

When a window resizes, redactions stay where they should. Hide a sidebar, the box does not slide off it.

Three fill styles

Solid color, animated noise / static, or a custom image. Pick what blends in best for the call you are on.

Configurable

Custom hotkeys and redaction style. Optional run-on-startup. Lives in the system tray, no taskbar entry.

Quiet

Near zero CPU until you actually press the hotkey. It is happy doing nothing in the background.
