Ethical Considerations & AI Disclosure

Using AI tools responsibly is crucial. Prioritize transparency with your audience. Consider adding a small disclaimer if a significant portion of your newsletter is AI-generated. The main ethical concerns are copyright (ensure your source material is original) and factual accuracy. Never skip the human review process to ensure the AI hasn't misinterpreted data or created misleading information. Authenticity builds trust that automation alone cannot.
