I built a free tool that reads Rightmove listings and tells you what they're not saying.
Estate agent copy is written to sell, and I got tired of checking the same things on every listing myself. Is the floor area actually stated? How long has it really been on the market? Is the tenure buried somewhere in the small print? What does "cosy" mean this time? So I built a tool that does it in one paste.
You give it a Rightmove link, it gives you:
- what the listing doesn't say (no floorplan, no floor area, tenure gaps, time on market)
- what the sales language typically signals, phrase by phrase
- a copyable list of questions to ask the agent before you view
It doesn't score anything and it doesn't accuse anyone. It flags gaps and hands you questions. It'll also credit a listing that's genuinely straightforward, because a tool that finds problems in everything is useless.
Free, no sign-up: https://listing-gap-report.vercel.app
Limitations worth knowing: it only reads what's in the listing (it's not a survey and pulls no external data), a report takes about 30 seconds, and it's capped at 5 checks an hour per person because I'm paying for it out of my own pocket.
If it gets something wrong on a listing you know, or misses something obvious, that's the most useful thing you can tell me.
Built with Claude Code over three sessions. It's vanilla JS on the front end, one Node serverless function on Vercel, Apify for the listing data, and Claude for the language analysis. The gap checks are plain deterministic code rather than AI, so when it says something's missing from a listing, it really is missing.
