Reach out on Slack ## Characters A **character** is a complete interactive AI persona you build on Equos. It has a visual identity, a voice, a personality, and the knowledge and abilities it needs to hold meaningful conversations. Setting up a character in the Equos Studio Every character is assembled from six building blocks: The visual identity of your character. A single image—photo, painting, illustration, or AI-generated—is enough to bring it to life with accurate lip-sync and expression. How your character sounds. Pick from a catalog of voices or bring your own via supported TTS providers. The personality and behavior. Define tone, identity, role, and scope through instructions—your character can be a coach, a tutor, a support rep, or any persona you imagine. A knowledge base the character can draw from (RAG). Upload documents so it can answer questions grounded in your own content. Actions the character can take—calling APIs, looking up data, triggering workflows—so it can do things, not just talk. The opening line your character speaks when a conversation starts. Sets the tone and guides the user into the experience. Want inspiration?
