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.
Grok API — direct access
A REST endpoint onto Grok with no wrapper prompt and no added filtering of its own.
It is aimed at developers who want the model's own behaviour rather than a vendor's interpretation of it.
