Dialogue
Paste a conversation, start from an idea, or dictate a rough scene. You read the script before anything is generated.
Dialogue, in motion
Some conversations deserve a second life.
JST4 turns a written dialogue into an original animated chat video — distinct roles, real voices, and a look that stays yours.

Made for stories that begin as text
Not another template. A small production studio for the conversation itself.
JST4 is built around pacing, roles, and readable mobile-first motion — without borrowing another messenger’s identity.
A clear path from script to screen
The guided flow, end to end.
Style
Pick an original visual system — light or dark, calm or playful — and see the scene in the frame it will ship in.
Voices
Give every role its own voice and delivery, and listen before you spend a credit.
Export
Render a vertical video, download it, or share it privately with an AI-generated disclosure.
What you actually get
Details that survive the small screen.
Original themes
Six visual systems, light and dark. None of them borrowed from another messenger.
A voice per role
Delivery is cast per role, not per project — and auditioned before anything is generated.
Ready to post
1080×1920, sized for a vertical feed, with the bottom band left clear for the platform’s own controls.
Your language
The dialogue and the voices follow the language you write in. You set the project’s language yourself.
Private by default
Your project is not a public feed. Nothing leaves the studio until you share it.
Disclosure built in
Every export carries an AI-generated disclosure and provenance metadata.
Your voice, your call
Spoken dialogue, or a scene that sings.
Keep roles distinct with natural speech, or explore musical delivery where it is available. You choose the direction before a single credit is reserved.
Two roles, natural pacing, a typing beat between lines. Timing is measured, never guessed.
The same conversation delivered as a song and aligned to the finished recording. JST4 sets no length limit here — the arrangement decides. Beta.
Start with a line
Make the chat worth watching.
Bring a dialogue, an idea, or a voice note. The studio takes it from there.
