Alethea AI is an AI tool that enables the creation of interactive AI characters using natural language, allowing for text-to-character creation. It allows users to generate characters with distinct appearances, voices, intelligence, and personalities through providing a natural language description. The AI characters can be owned, customized, and trained, then traded or used across dApps and AI protocols. Alethea AI's CharacterGPT is the first multimodal AI system for generating interactive AI characters.
