Patchwork

Patchwork is a collaborative platform launched by Midjourney. According to the site, it uses AI technology to let users co-create fictional worlds on an infinitely large canvas, offering a novel creative space where users explore or build new worlds by linking different sandboxes together. Its primary advantage is limitless creative potential combined with AI-assisted content generation, so creators can quickly assemble complex fictional universes without starting from a blank page. Features include click-and-drag navigation, portals that lead into different sandboxes, a toolbox that generates new story elements, draggable fragments with multi-select and delete, an action bar, multiplayer collaboration with visible cursors and notes, world permissions, and saving a world as a JSON file.

- Build shared worlds on an infinite, zoomable canvas

- Link different sandboxes together using portals

- Generate story elements like characters and factions with AI

- Collaborate live with others and export the world as JSON

- Writers developing worldbuilding, lore, and character backgrounds

- Game designers prototyping environments, maps, and characters

- Filmmakers planning scenes, settings, and plotlines together

- Collaborative creative teams who think better on a shared canvas

The site says a free trial is offered but does not disclose specific pricing, so cost is unclear and may change once plans are published, which makes long-term planning hard. It is a niche tool aimed at fictional worldbuilding, so it will not replace general design, note, or project apps for everyday work. Multiplayer value depends on other people joining your world, and solo use is more limited than the marketing suggests. Because it comes from Midjourney and sits behind a trial, access rules, features, and any future pricing are outside your control, so export important worlds as JSON rather than trusting the platform to keep them forever.
