Everything you need to triage fast

Blazing-fast review

A big, distraction-free preview shows each image or video full-size, so you can decide at a glance.

Keyboard-first

Keep, trash, undo, and navigate without the mouse to clear a whole folder with a few keys.

Thumbnail carousel

A filmstrip along the bottom highlights where you are and lets you jump to any file instantly.

Always know where you are

The current folder sits in the title bar, with a live position counter plus per-file and whole-folder size estimates.

Safe & reversible

Deletions are staged and undoable for the whole session, then committed to the Trash, never a hard delete.

Private & sandboxed

Runs fully offline using native macOS APIs, touching only the folders you choose.

Under 2 MB

No bloat, no Electron. Small, lightweight, and it just does the job.
