Character AI — create custom characters & chat
The API creates a character with a defined personality, traits and backstory, and keeps it consistent across a conversation.
Games, companion apps and interactive fiction use it where a generic assistant would break immersion.
Generative AI API — GPT-4o integration
A REST interface onto GPT-4o for content generation, task automation and analysis, without the wiring an SDK integration needs.
It suits products adding a generative feature rather than building an AI platform.
