StageMaster

For Mac

Your coding agent can
make your product videos.

Tell Claude Code or Codex what the video should show. StageMaster clicks through your app, films it in one take and adds a natural voiceover.

Download for Mac

It's free, with every feature.
Your videos carry a small watermark until you buy a license.

We asked Claude Code for this one, and StageMaster filmed and voiced it.

We asked Claude Code for each of these. Here are the words it wrote, and the film StageMaster made from them.

The script

      How it works

      You ask your agent for a video.

      1. Claude Code or Codex writes the script. That's every line you'll hear, and every click behind it.
      2. StageMaster films it on your Mac. It clicks through your app the way the script says, and 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

      StageMaster comes with 54 voices.

      Every voice runs on your Mac, so there's no account to make. You can give each line its own voice.

      Without an agent

      You can also 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.

      You finish the video where you made it. You can trim it, zoom in, add subtitles and a background, and upload it to YouTube.

      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.

      Every feature is free.

      If you'd rather your videos didn't carry our name, a license takes it off.
