Who it’s for

Lawyers, paralegals, compliance teams and people dealing with contracts. Not legal advice.

Adapt it to your industry

  • Freelancer: understand a client contract before signing
  • Small business: draft a first version of a simple policy for a lawyer to review
  • Real estate: summarize a lease in plain words

Step by step

  1. Remove names and private details from the document first.
  2. Open ChatGPT, Claude or Grok and paste the prompt below with the text.
  3. Ask for a plain-language summary, a list of risks and questions to ask.
  4. Check every point against the actual document; AI can miss or invent things.
  5. Have a qualified lawyer review anything important before you rely on it.
  6. Save the prompt as a checklist for the next document.

  • Show the workflow to colleagues in your firm or network.
  • Offer fixed-fee reviews to small businesses you know.
  • Write a short guide on the topic and share it on LinkedIn.
