Butterfly Effect
Butterfly Effect

Change one thing. Watch everything follow.

Pick a moment in history, a film, a show, an anime, a comic, a book or a whole universe. Rewrite any piece of it and the rest of that world rewrites itself: the newspapers, the timeline, the episodes and the films.

    A new arc

    Every world runs on the same engine

    Seven worlds, one idea. Comics, lore and books are already live as their own sites; history, TV, films and anime start here.

    One world underneath

    The people, places and things that matter, kept in a Who and what list under every world. Every rewrite, script and preview is drawn from it, so nothing contradicts anything else. Change a line and the world rewrites around it.

    Edit anything

    Rewrite a headline or a line in a scene. That becomes the change, and everything after it is worked out again. Everything before it stays.

    Keep every version

    Each edit saves a new version of your world, kept for you and waiting when you come back. Flip between them and branch from any of them.

    Make what you want

    A front page, a season, a two hour film. Watch a free preview of the opening, choose what to make and see the price before anything is made. Save any front page, poster or cover as a picture.
