StageMaster

For Mac

Your product videos,
made for you.

Ask your coding agent for a video. StageMaster performs it on your Mac, records it in one take, and adds a natural voiceover.

The StageMaster editor: the script's lines on the left, the recorded take with its subtitle in the middle, the voice settings on the right, and the voiced lines on the timeline below.

How it works

One request. One take.

  1. Ask your agent for a video. Claude Code or Codex writes every line, and every click behind it.
  2. StageMaster performs it. Your Mac plays it out while StageMaster records it in one take.
  3. Change a line, record again. When it feels right, export it.
The Lines panel in StageMaster: three spoken lines with their timing, two reads of each, and each one approved.
The voice settings in StageMaster: the Kokoro model running on the Mac, a cast, the voice Kore, the gap between lines, and one generation per line.

Natural voices

54 voices, built in.

Every voice runs right on your Mac, with no account to make. Give each line its own voice.

Record it yourself

Prefer to record it yourself?

Record your screen as usual, then type the lines you want spoken. StageMaster voices them over your recording.

The StageMaster timeline: the screen recording on the video track, and the spoken lines L1 to L12 as voice waveforms below it.

Everything a product video needs. Trim, zoom, subtitles, backgrounds, and YouTube upload, right where you made it.

Free, with every feature.

Your exported videos carry a small watermark. A license removes it, once and for good.
