Privacy note
Your topic brief is sent securely to our AI processing service for generation. It is not stored after the response is returned and is not used to train AI models.
When not to use this tool
Not a substitute for disclosing sponsored content or complying with legal claim requirements. Always review generated captions before posting — AI can produce inaccurate claims, especially about products, prices, or health topics.
