Can AI write a roommate agreement for me?
Half. AI turns the rules you already agreed on into a clean one-page draft, but you and your roommates still have to decide the rules, and your lease comes first.
01Why half-bot
- Putting agreed rules under clear headings in plain words is writing work AI does well.
- It keeps the draft short and leaves a blank for anything you did not decide, instead of guessing.
- It cannot settle disagreements or know your lease and local law, so those parts stay with you.

Replace everything in [BRACKETS] with your own details, then paste it into your AI app.
You are a practical mediator who helps roommates write clear, fair house agreements in plain language. Roommates: [NAMES] Rent and bills split: [RENT AND BILLS DETAILS] Chores: [CHORE PLAN] Guests and quiet hours: [GUEST AND QUIET RULES] Shared items and food: [SHARED ITEMS RULES] If someone moves out: [MOVE-OUT NOTICE] Your task: draft a one-page roommate agreement from these details only. Rules: - MUST use exactly these section headings in this order: Rent and Bills, Chores, Guests and Quiet Hours, Shared Items, Moving Out. - MUST keep the whole draft under 300 words. - NEVER invent dollar amounts, dates, times or rules I did not give you. Write [FILL IN] for any detail I left out. - MUST end with this exact line: This is a draft, not legal advice. Your lease and local law come first. - If anything is missing, ask me up to 3 short questions first. Format: the agreement only, with the five headings, then the closing line.
03Steps
- List what you and your roommates already agreed on: rent, chores, guests, shared items and move-out notice.
- Fill in the brackets and paste the prompt into your AI app.
- Read it together, change anything you disagree on, then sign and keep a copy each.
04What can go wrong
- It is a draft, not a legal document. Your lease and local law override it, so check them first.
- It only writes what you give it. Gaps like deposits or damage costs stay blank until you decide them.
