Record the whole story.
Capture a display, window, region, or USB-connected iPhone or iPad. Bring in system audio, microphone, and camera when the demo needs context—not just pixels.


Let the camera follow the action.
Automatic camera movement follows clicks and the focus of each action. After recording, the framing, virtual pointer, click effects, and motion blur are still yours to refine.

Let an external agent handle repetitive edits.
Connect Claude Code, Codex, or another external agent through the Koma CLI, available to every user. With your own local transcription tools, prepare captions, find pauses, adjust speed, and coordinate camera movement.
Preview the editing plan before applying it, then return to Koma to export the final video. AI tools, transcription tools, and their service fees are not included in a Koma license.
