Charstar

Charstar is an AI-powered platform for creating, managing, and interacting with customizable virtual characters. Users can design characters with detailed personalities, backstories, and conversational styles, then engage with them in natural, context-aware dialogue. The tool supports multi-character chats, allowing users to simulate group conversations, roleplay scenarios, or narrative scenes where several AI personas interact with each other and the user.

Charstar provides fine-grained control over character behavior through configurable traits, prompts, and example dialogues, enabling consistent and predictable responses aligned with each character’s intended role. Users can organize characters into collections, reuse them across different conversations, and iteratively refine their profiles based on interaction history.
