I built Infinite Realms, an AI-powered text-based roleplaying game where players can create a character, enter different worlds, and continue evolving across sessions through persistent memory and campaign state. The platform is designed around dynamic storytelling, evolving characters, long-term progression, and central storylines that respond to player choices. Instead of resetting after each session, Infinite Realms keeps track of character progress, objectives, inventory, relationships, reputation, and world state so the experience feels like a living RPG campaign. I built the platform using Next.js, the Vercel Agent SDK, Supermemory, Drizzle ORM, PostgreSQL with Neon, Python, Modal, ComfyUI, and OpenRouter. I handled the full product development process myself, including the frontend, backend, database structure, AI orchestration, persistent memory systems, world simulation, character systems, and generative storytelling pipeline. Infinite Realms is the first phase of a larger vision: building toward a persistent AI-driven RPG world that can eventually expand into more immersive experiences.
