Native screen recording and automatic camera editing for macOS
Your screen.Your story.
Record a product demo, a tutorial, or an idea worth explaining. Capture your screen, voice, and camera, then refine the pacing, framing, and captions.

Record exactly what you want
Record a full screen, a window, a region, or a USB-connected iPhone or iPad. Choose your audio and camera sources, then continue editing in the same project.


- Capture a full display, one window, or a custom region
- Choose a 3-second or 5-second countdown with a start sound
- Paused time never enters the finished recording
Give each action a clear focus.
The camera tracks clicks and the focus of each action, so viewers always see what you are doing. After recording, the camera framing, pointer size, and click effect are all still adjustable.
Automatically follows clicks and the focus of each action
Pointer size from 50% to 300%
Drag and resize the camera frame directly on the canvas

Let your AI handle the repetitive edits.
Connect Claude Code, Codex, or another external agent through the Pro CLI. With your own local transcription tools, prepare captions, find pauses, and coordinate camera movement.
Preview the editing plan before applying it. AI tools, transcription tools, and their service fees are not included in a Koma license.
