The Best AI Writing Tools for Every Kind of Writer

How to use AI writing tools well

• Write the first draft yourself when it matters. Use AI to improve your words, not replace your thinking.
• Accept suggestions selectively. Not every change makes text better, and too many can flatten your voice.
• Check facts and quotes. Writing tools polish text; they don't verify it.
• Protect private text. Read the privacy terms before pasting confidential documents.
