The visit
Five takes land. You keep one.
A run the studio recorded on September 26: one character, five styles. Press Generate and the takes land as they did that day — then keep the one you would keep.

ReferenceThe still the run started from.Press Generate: the five takes land at the pace of the recorded run.
This page spends nothing and sends nothing. The chip is the run’s recorded total, rounded up to the cent as the desk rounds.
Awaiting replay
Made by Tin Kaiju, the studio behind Kiju, with the studio’s engine — the providers Kiju calls. You are replaying the studio’s run, not generating a new one.
How it works
Four truths
- DraftKept
The crew proposes. You decide.
Agents write the brief, the script and the shots. Everything they make is a draft until you keep it. They never approve their own work.
The price is on the button.
Every paid action says what it costs before you press it. Set a budget per project; Kiju refuses past it, and never spends without an estimate.
~/Kiju/Wind-Up City/Your channel is a folder.
No Kiju account, no Kiju server, no telemetry. Projects stay on your Mac, keys in the macOS keychain. Requests go only to the providers you choose — and Kiju shows what leaves, first.

The next episode remembers.
The rules you approve in the bible bind every episode after. The crew writes from them, and the continuity check reads each new script against them, citing the rule it relies on. A retired rule keeps its reason.
Five rooms
One desk, five rooms.
The same channel folder, read by five rooms. Each one opens on what you kept in the one before.





Channel
Audience, promise, voice — and the bible: what is approved, what is proposed, what was retired and why.
