How to Use AI Writing Tools Responsibly
-
- Treat AI output as a draft. Edit it so it reflects your voice, experience and knowledge.
- Check facts. Verify names, statistics, quotes and links. AI tools can state wrong information with confidence.
- Add original value. Readers and search engines respond to your examples, screenshots, data and first-hand observations, which AI can’t supply.
- Avoid mass-producing thin content. Publishing large amounts of generic AI text can harm trust and search performance.
- Protect confidential information. Don’t paste private client or business data into tools without authorization.
- Be transparent where it matters. Follow any disclosure rules from clients, publishers or platforms.
