A lightweight, native screenshot capture and markup tool for macOS. It lives in your menu bar, captures stills via ScreenCaptureKit, and opens a fast annotation editor — arrows, callouts, step badges, blur, the works. Swift + SwiftUI, zero third-party dependencies, single ~2 MB binary.

Made with Claude. This project — the spec, every line of code, the app icon, the tests, and these docs — was written by Claude Fable 5, Anthropic's Claude Code model, working under human direction. The logic core and renderer are covered by 110 unit tests run on every push (see TESTING.md); the capture UI is verified against a manual checklist.

With v2 — screen draw, frozen zoom, and board modes — the original vision is complete. Claude takes a bow. 🎩

• Capture modes: region drag-select with a live size badge and a magnifier loupe for pixel-perfect edges, click-to-capture window picking, full screen (per display), and 3/5/10-second timed capture with an on-screen countdown. Region captures snapshot the screen the moment the overlay opens, so the result is instant and exact.
• Screen draw (⇧⌘D): ZoomIt-style presentation mode — freeze the screen and draw directly on it with the editor's tools, then ⌘C to copy, ⌘S to save, ⌘E to keep refining in the full editor, or Esc to walk away. Single letters switch tools (P pen, A arrow, B box, …) just like ZoomIt. W and K swap the frozen screen for a whiteboard or blackboard when you'd rather sketch on a clean surface.
• Frozen zoom (⇧⌘Z): freeze the screen and magnify up to 8× — scroll or arrow keys zoom toward the cursor, moving the mouse pans, and ⌘C/⌘S/⌘E export exactly what's on screen. Press any drawing key to annotate the magnified view; double-click or Esc exits.
• Post-capture panel: every capture pops a small floating panel — edit, save, copy, share, or discard. It never steals focus from what you're doing.
• Markup editor: arrows, lines, rectangles, ellipses, freehand pen, highlighter, text, speech-bubble callouts, auto-numbered step badges, pixelate-blur, and redact. An Office-style tool ribbon shows each tool's name (collapsible to compact icons). Select, move, and resize via drag handles; double-click to re-edit text. Full undo/redo. Crop, plus border / drop shadow / rounded-corner effects on export.
• Settings (⌘, or via the menu bar icon): record your own capture shortcuts, launch at login, show/hide the cursor in captures, toggle the shutter sound, auto-copy every capture to the clipboard, pick what happens after each capture (panel, copy, save, or straight into the editor), and either get asked where to save or quick-save into a folder of your choice.
• Output: PNG (default) or JPEG with a quality slider, correct DPI metadata for HiDPI displays, straight to the clipboard, or the macOS share sheet (AirDrop, Messages, Mail, …). All exports are flattened at full pixel resolution.

Easiest: grab the zip from the latest release, unzip, and drag the app to /Applications. The app isn't notarized, so on first launch use right-click → Open (or, on newer macOS, System Settings → Privacy & Security → Open Anyway after the first blocked attempt).

Requires macOS 14+ and the Xcode Command Line Tools (no full Xcode needed).

./build.sh                  # builds dist/Nice Shot.app
./build.sh --beta           # builds dist/Nice Shot Beta.app (separate bundle
                            # id — installs and gets permissions alongside the
                            # release app, for testing unreleased builds)
swift run NiceShotTests     # run the unit tests

Don't run the release and beta apps at the same time — whichever launches second can't register the global hotkeys.

Move the app to /Applications if you want Launch at login to work reliably. The bundle is ad-hoc signed, so Gatekeeper on another Mac will warn on first open (right-click → Open).

The first capture triggers the Screen Recording permission prompt. Grant it in System Settings → Privacy & Security → Screen & System Audio Recording, then relaunch the app — a one-time macOS requirement.

All shortcuts are configurable in Settings.

In the editor: ⌘Z / ⇧⌘Z undo/redo, ⌫ deletes the selection, ⌘S saves, ⇧⌘C copies the flattened image, Return applies a pending crop and Esc cancels it.

Annotations are stored in image-pixel coordinates, and one renderer draws both the live canvas and the exported image, so what you see is exactly what saves.
