Annotate like you mean it
Arrows, boxes, highlighter, text, numbered steps, spotlight and a pixelate brush. Scribble a circle and Koji cleans it into a perfect one. Hold Ctrl to keep it hand-drawn.

Copy text from anything
CtrlT reads every word in your snip with Windows' built-in OCR. Offline, instant.
Search what you see
CtrlG sends the snip to Google Lens. Identify a font, a plant, a part, a place.
Snip inside a snip
Add snip drops a second capture on top. Move it, resize it, crop it, give it a border or a deep shadow.

Questions
Is it really free?
Yes. No trial, no account, no watermark, nothing uploaded. Your snips stay on your PC.
Does it replace Win+Shift+S?
By default, yes: Win+Shift+S and PrtSc open Koji instead of the Windows snipper. Both can be turned off in Settings.
Where do my files go?
Quick-saves land in Pictures\Koji, recordings in Videos\Koji. Both folders can be changed in Settings, and auto-save is optional.
How do I uninstall it?
Quit it from the tray and delete Koji.exe. Settings live in %APPDATA%\Koji if you want them gone too.
Why is it so small?
Koji is written in Rust and talks to Windows directly: GDI+ for drawing, DXGI for capture, Media Foundation for video, WinRT for OCR. No browser engine, no framework.
