kuja.dev

kuja.dev is a small Mac utility studio that ships two quiet, focused tools: DropK and EQK. DropK adds a menu bar shelf where you can drop files, folders, links, text, or clipboard items — anything that belongs to the current task but doesn't have a home yet. EQK gives every app its own 10-band equalizer, with AutoEq headphone correction, per-app audio routing, a local FLAC player, and synced lyrics. Both tools are designed to stay out of your way until you need them.

DropK works like a temporary holding tray. You can drag in a screenshot, paste a URL, or save a note, then pin the shelf while you work and hide it when you're done. Saved sets let you bring back the same collection of items for recurring projects. EQK processes audio entirely on your Mac — no cloud, no latency. You can route Spotify through one EQ, your browser through another, and apply headphone correction profiles for compatible headphones. It also includes a lightweight FLAC player with lyrics that sync to the track.

These tools are built for people who spend a lot of time on their Mac and want utilities that do one thing well. DropK is useful for designers, writers, or anyone who juggles multiple files during a task. EQK appeals to music listeners, podcasters, or gamers who want fine-grained control over audio per app. Both are free to start (DropK has a Pro option, EQK is a one-time unlock) and require macOS 15.6 or later.
