Correct mistakes without restarting the story
When a character mixes up a detail, identify the mistake and give the correct version. Then continue with the next question or scene. Avoid repeatedly testing memory with vague questions: a clear reminder is usually more useful for progressing the conversation. AI can still generate an incorrect answer, so check facts that matter outside the fictional story.
Try a continuity check
Choose an invented destination for a shared journey. Explain why it matters, continue the conversation, and return to it later with a short reminder. Compare what stays consistent and clarify one missed detail before moving the story forward.
