It's a [AGREEMENT TYPE, e.g. apartment lease]. Compare them line by line and list every change in plain words. Put the changes in a table with four columns: what changed, the old wording, the new wording, and what it means for me in everyday terms. Start with money: price, payment dates, late fees, deposits and automatic increases. Then cover length, renewal and cancellation terms, notice periods, and anything that was removed. Flag the three changes I should ask about first, and write them as short, polite questions I can send to [WHO YOU DEAL WITH, e.g. my landlord]. Don't give legal advice. If something's unclear, say so and suggest I ask a professional. ``` ## Step by step 1. Open Claude, ChatGPT or Gemini and start a new chat 2. Attach the old agreement and the new renewal as PDFs 3.
