A real editor, not a trimmer
Viewport, inspector, and a timeline with draggable zoom blocks. Swap the background to a macOS wallpaper, a gradient, or a solid — tune padding and shape live.

A free, open-source Screen Studio alternative for macOS. Record your screen, webcam, and system + mic audio in-process with ScreenCaptureKit, then let the editor auto-zoom on every click, smooth the cursor, drop your capture onto a gorgeous wallpaper, and export to mp4 or gif.

● AUTO-ZOOM ON CLICK
Every detail tuned for beautiful demos.
Auto-zoom on click
A cursor sidecar records every click while you record. The editor derives smooth zoom segments from it — punch-in where it matters, automatically.
Cursor overlay
Cursor position, clicks, and shape transitions are tracked at ~poll rate and replayed as a clean, oversized overlay on top of your footage.
Display, window, or area
Per-display transparent picker overlays let you grab a whole screen, a single window, or drag out an exact region before the 3-2-1 countdown.
In-process, no sidecar
Recording is a native SCStream writing mp4 directly via ScreenCaptureKit. No ffmpeg in the capture path — just one clean artifact per take.
Webcam bubble
Your camera records to a hardware-encoded sidecar via AVFoundation, kept in sync with the screen. The editor composites it as a draggable, resizable bubble.
System + mic audio
ScreenCaptureKit captures system and microphone audio as separate, frame-aligned tracks — independently trimmable and mutable on the timeline.
Export to mp4 / gif
An offline pipeline composites screen, camera, and background on WebGL2 and encodes to mp4 or gif — straight to a file or the clipboard.
Pause, resume, restart
Full transport control from a frameless always-on-top pill — or stop from the macOS menu bar and the app finalizes the same artifact.
From key-press to graded clip.

Edit, beautify & export
The editor reads the sidecars, derives auto-zoom, paints the cursor overlay, frames it on a wallpaper, then exports to mp4 or gif.
