Charms is a consumer application where users can create, discover, and interact with AI characters that have persistent memory, distinct personalities, voice, and visual identity. Unlike closed companion platforms, each public character on Charms has its own on-chain treasury funded by a share of market fees, allowing creators to build characters as owned creative businesses rather than content hosted on someone else's infrastructure. Characters reason over recent conversations, relationship context, and emotional patterns, building understanding of each user over time instead of resetting after every chat. Fans can chat, discover, and participate in the growth of characters they believe in.
