Set

Set is a game-building and world-generation platform designed for developers, players, and AI agents. It provides tools to roll characters, items, and parties from seeded, weighted tables, making results reproducible when a seed is supplied. Generated characters include classes, traits, attributes, equipment, and derived statistics; items include details such as grade, material, and orb value. Users can also craft items by spending orbs, with higher spending improving the chances of better results.

Set supports development through its skills, API, and Model Context Protocol server, alongside documentation and reference guides for character and item models, combat, animations, scenes, materials, and other systems. Its showcase features Anima models, weapons, talents, effects, and teams. The platform also includes an adventure mode in which a party explores a maze and automatically encounters enemies, with options to pause or step through combat. Battles use initiative, stamina, weapons, armor, and status effects, while seeded characters and encounters support repeatable play. Set offers an integrated environment for exploring game systems and building experiences around them.
