A conversation, made watchable.

JST4 begins with a dialogue — pasted, drafted from an idea, or transcribed from a recording. You stay in control of the words before you choose the presentation.

1. Shape the dialogue. Review roles, messages, language and pacing.
2. Choose the visual world. Pick one of six original compositions, a light or dark palette, and the backdrop it plays over.
3. Direct the delivery. Assign a voice to each role and choose spoken or, where available, music-led delivery.
4. Export and share. JST4 renders a vertical video. Download it or create a revocable private link.

JST4 does not operate a public gallery. Projects remain private unless you choose to share a secret link.
