Summon Worlds is an AI-powered platform that enables users to create and explore immersive worlds through text-based prompts and interactions. The platform leverages advanced natural language processing (NLP) and generative AI models to bring user-defined characters, locations, and narratives to life.

Key features of Summon Worlds include:

- World Creation: Generate detailed worlds, including characters, locations, monsters, and items, from simple text descriptions.
- Interactive Storytelling: Engage in dynamic conversations and gameplay with AI-generated characters and entities within the created worlds.
- Dungeon Master Tools: Automatically generate balanced stats, abilities, and actions for characters and creatures, compatible with popular tabletop RPG systems like Dungeons & Dragons 5th Edition.
- Collaborative Worldbuilding: Share and explore worlds created by the Summon Worlds community, enabling collaborative storytelling experiences.
- AI-Powered Artwork: Generate artwork and visuals to accompany the created worlds and characters.

Summon Worlds utilizes a proprietary AI foundation model trained on a vast corpus of fantasy literature, game rulebooks, and creative writing to understand and generate coherent narratives, characters, and worlds. However, the specific details of this model or the underlying large language model (LLM) are not publicly disclosed.

The platform is available as a web-based service, without any dedicated mobile app, API, or SDK mentioned. It was founded by Lucas and Rohan in 2024 and received seed funding from Y Combinator in the same year.

Pricing information for Summon Worlds is not provided, but it likely follows a freemium or subscription-based model, offering basic features for free and premium capabilities for paid users.

Summon Worlds caters to a wide range of users, including writers, storytellers, game masters, and tabletop RPG enthusiasts, as well as anyone interested in exploring and creating rich, imaginative worlds. Its AI-driven approach to worldbuilding and interactive storytelling can inspire creativity and enable unique collaborative experiences.
