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

Intelligent camera algorithms track clicks and points of interest automatically. After recording, every zoom level, virtual pointer style, and motion blur setting remains fully adjustable.

Scriptable editing with external Agents.
Connect Claude Code, Codex, or other external agents via the free Koma CLI. Using your own local transcription tools, prepare captions, detect pauses, adjust clip speeds, and coordinate camera moves.
Inspect and verify the editing plan before applying it, then return to Koma to export the final video. AI tools, transcription utilities, and their associated fees are not included in a Koma license.
