AI writing tools are genuinely useful, and genuinely limited. Understanding both sides helps you get value from them without publishing something you regret.

What AI writing does well

  • Getting started: producing a first draft or outline in seconds.
  • Rephrasing: offering alternative ways to say something.
  • Summarising: condensing text you provide into shorter versions.
  • Brainstorming: generating lists of ideas, angles and questions.
  • Adjusting tone: making text more formal, casual or concise.
  • Structuring: suggesting headings and a logical order.

What AI writing can't reliably do

  • Guarantee facts: AI can produce confident, plausible and wrong statements, including invented sources. Always verify.
  • Have real experience: it cannot tell you what it was like to use a product or run a business. Only people can.
  • Sound like you by default: without guidance and editing, output tends toward generic phrasing.
  • Know what is current: depending on the tool, information may be out of date.
  • Take responsibility: the person who publishes is accountable for what is said.

Practical rules for using AI in writing

  1. Keep the purpose and argument yours.
  2. Treat AI output as a draft, never a final version.
  3. Verify every factual claim against a reliable source.
  4. Never present AI-generated content as personal experience.
  5. Edit until it sounds like you.
  6. Be open about AI use where your audience would expect to know.
