Character.ai Terms of Service

In an update detected on July 17, 2026, Character.AI modified UI text and workflow descriptions in its Terms of Service related to Lorebook (contextual world-building) features. The changes clarify that published Lorebooks take effect immediately in linked characters' chats, that characters can only use one Lorebook at a time, and that linking a character to a new Lorebook will stop using a previously linked one. The updated language also describes the user experience of linking and publishing Lorebooks more explicitly, though these appear to be interface and messaging updates rather than substantive changes to the underlying service terms or user rights.
