When you're choosing between two rentals, the listings blur together. This five-minute workflow works in any AI assistant — ChatGPT, Gemini, Claude, Copilot, Le Chat, DeepSeek, or whichever you already have — and scores both places against the priorities you set yourself.

💡 Tip: tap a step’s number when you finish it — a green tick appears and your browser remembers how far you got.

✅ Before you start

An account with any AI assistant you already use (free or paid — both work for this).
The full text of both rental listings, copied from the listing page or app. Screenshots alone won't work — only pasted text.
A short list of what actually matters to you (commute, noise, utilities included, lease length, pets, parking — three to six items is enough).
About 15 minutes.

Step 1 of 6

Open a new chat and paste both listings

Start a fresh conversation — don't drop this into an old chat, or the assistant will weigh your rentals against whatever you were talking about before. In the message box at the bottom of the screen, paste the first listing, leave a blank line, then paste the second one. End the message with a one-line note telling the assistant what it's looking at.

💬 Try typing this"Listing A — 2-bed in Eastside, $X/month, 12-month lease. — — Listing B — 1-bed + den in Northgate, $Y/month, month-to-month. Compare these two rentals."➤

If the listing is mostly images or a PDF, you'll need to type out the key facts by hand — assistants can't reliably read screenshots unless your plan includes file upload or vision, and even then the result varies.

✅ You'll know it worked when

you can scroll up and see both listings sitting in the chat, and the assistant acknowledges them in its first reply.

Step 2 of 6

Tell the assistant your priorities and how much each matters

Send a second message that lists the things you care about and gives each one a weight — how much it should count in the final score. Weights are how you stop the assistant from treating "has a dishwasher" as equally important as "20-minute commute." The format that works best is a numbered list with a 1–5 or 1–10 weight next to each priority.

💬 Try typing this"Here are my priorities, weighted 1–5: 1) Commute under 30 min by transit (5). 2) Quiet street, no main road (4). 3) Utilities included in rent (3). 4) Allows my cat (5). 5) In-unit laundry (2). Score both listings against these."➤

If your assistant has a "memory" or "custom instructions" setting (different apps call it different things), you can save the weights there once and reuse them for future comparisons.

✅ You'll know it worked when

the assistant restates your priorities back to you without being asked — that means it actually loaded them into the conversation.

Step 3 of 6

Ask for a clean side-by-side table first, before any scores

Now ask for a comparison table with one row per feature and one column per listing. Don't ask for scores yet — you want a neutral snapshot of what each listing actually says, so you can spot places where the assistant fills in gaps with guesses. The clearer this table is, the more honest the scoring will be in the next step.

💬 Try typing this"Make a table with these rows: rent, lease length, square feet, utilities included, parking, laundry, pet policy, commute time to downtown, nearest noise source. One column for Listing A, one for Listing B, one for 'verified or missing.' If a fact isn't in the listing, write 'not stated.'"➤

If the table renders as plain text instead of a real grid (some mobile apps do this), ask the assistant to "rebuild it with pipes and dashes" and it will produce a text-only version that still reads clearly.

✅ You'll know it worked when

every row is filled with text from the listing — or says "not stated" — instead of the assistant inventing something to fill the gap.

Step 4 of 6

Add weighted scores and a recommendation

Send a third message asking the assistant to score each listing on your weighted priorities and add a one-line recommendation at the bottom. This is the step that turns the table into a decision. The math is simple: multiply each priority's weight by the listing's score on that priority, then add them up. The listing with the higher total wins — on your priorities, not on someone else's.

💬 Try typing this"Now score both listings 1–10 on each priority from Step 2, multiply by the weight, and show the totals. Add a two-sentence recommendation naming which one wins on my priorities and why."➤

✅ You'll know it worked when

If the assistant hedges with "it really depends on you," that's a sign it didn't read your weights carefully — nudge it with "use the weights literally, don't substitute your own." You'll know it worked when you see a final number for each listing and the recommendation names a clear winner with a stated reason.

Step 5 of 6

Push back on vague answers and list what to verify

Before you act on the recommendation, ask the assistant to flag anything it had to guess at, plus every "not stated" cell from the table. This step is the safety net — assistants can sound confident about facts that aren't actually in the listing, and a lease you signed based on a wrong assumption is an expensive lesson. The honest answer often involves several things you need to ask the landlord directly.

💬 Try typing this"List every fact in the table you marked 'not stated' and anything you had to infer. For each one, write a one-line question I can email the landlord."➤

If the assistant invents a detail (like "utilities are included" when the listing didn't say so), that's a hallucination — when an AI confidently states something that isn't actually there. Call it out with: "You made that up; the listing didn't say it.

✅ You'll know it worked when

Replace with 'unverified, ask landlord.'" You'll know it worked when you have a short, concrete list of questions to send before you sign anything.

Step 6 of 6

Save the prompt structure as a reusable template

Copy the three prompts you sent (Steps 1, 2, and 4) into a notes app and label it "Rental comparison template." Next time you're weighing two places, open a new chat, paste the template, swap in the new listings and weights, and you'll get the same scored comparison in minutes — no setup, no re-thinking the structure.

💬 Try typing this"PROMPT 1: [paste listings + intro line]. PROMPT 2: [paste weighted priorities]. PROMPT 3: [paste score-and-recommend request]."➤

If your assistant supports a way to save reusable prompts (different apps call this Projects, Gems, custom instructions, or similar — check the menus if you're not sure), you can store the template there so it loads automatically next time.

✅ You'll know it worked when

the template is sitting in your notes ready to go the next time a listing site or a landlord's email hands you two options.

⚠️ Common mistakes

Letting the assistant pick your priorities. It will default to generic things like "location" and "price." Insist on your weights, even if they feel quirky — a quiet street might matter more to you than square footage, and that's the whole point of doing this yourself.
Pasting only the headline summary. The first paragraph of a listing is marketing. The fine print about utilities, parking, and pet fees is usually further down — paste the whole thing, or you'll be comparing ad copy instead of facts.
Trusting the score without checking the table. A 9/10 on "utilities included" means nothing if the listing never actually said that. Always read the table before you read the score, and send the "not stated" list to the landlord before you commit.

🚀 Try it now

Pick one priority that matters to you (commute, pets, quiet, anything), find two short rental listings — even made-up ones work for practice — and run Steps 1 to 4 in a fresh chat. You'll see the decision become obvious in under five minutes.
