How it works

1 · Bring a face, or don't

A photo or short video works. So does an anime character, a pet, or a description with no image at all — the model generates from the prompt in that case.

If the material shows a real person, you confirm you are that person or have their permission. Until that is on file, the character cannot generate anything.

The photo is what the character looks like: the video model uses it as the reference for every scene.

2 · Say what you want to happen

One sentence is enough. 'A rainy evening in Kyoto, she is an old friend I have not seen in years.' The system turns that into a structured scene — relationship, place, time, goal, tone — which you can edit.

The twelve cards on the homepage are starting points, not a menu. Anything you can describe works.

3 · Talk, and choose

Every reply comes with two things you can do next. Type freely instead if you prefer — the story handles both.

While you read, the continuations for those two choices are already being generated. That is why picking one lands in about fifty milliseconds instead of a few seconds.

4 · Video, only where it matters

Everyday interaction runs on avatar animation — lip sync, looped motion, expression. That is cheap, so text and voice are generous.

Full video renders the moments worth rendering: turning points, travel scenes, and anything you explicitly ask for. That is the expensive part, so that is what a plan meters.

Nothing is ever rendered for a moment that has not happened. There is no future to render — the world has not computed it yet. That rule is in the code, not the config.

5 · It remembers, and you control that

Facts worth keeping get written to memory and pulled back when relevant — not your whole history, only what matters to this character and this moment.

You can read every memory, edit it, delete it, or turn memory off for a character entirely.
