What it catches

▲
Temporada contracts
Seasonal lets dressed up as long-term rentals — the trap that costs people the most time.
▲
Prices too low to be real
Judged against the actual market for that neighbourhood and city.
▲
Money before a viewing
Deposits by transfer, cash or crypto, or a reservation to "hold" the flat.
▲
Pressure tactics
First to pay gets it, many people interested, decide today.
▲
Subletting
A tenant re-renting rather than the owner or an authorised agent.
▲
Self-contradicting adverts
Bills included in one line and 225 €/month in the next.
▲
Relisted boilerplate
Copy-pasted or machine-translated text from a booking platform.
▲
Missing basics
No photos, no description, no phone number — nothing you could check.

How it works

  1. Open a listing

    The extension reads the advert already on your screen: price, size, area, terms, description.

  2. One call to Jev

    Fourteen narrow questions are answered in a single request by TypeSafe's decision model, which returns calibrated probabilities rather than prose.

  3. A verdict you can audit

    Strong candidate, caution or skip — with every signal behind it named and scored.

Honest by design

An empty advert is not a safe one A listing with no photos and no text scores low on every risk factor because there is nothing in it. PisoCheck says "little to verify" and raises the score instead of rewarding the silence.
Questions it cannot answer are marked n/a With no description to read, the signals that depend on text are excluded from the score rather than guessed at.
It never calls an agency fraudulent It shows their profile, their other listings and a way to check them, and leaves the judgement to you.

Privacy

PisoCheck reads only the Idealista listing page you have open, and sends only that advert's public content in order to score it. No account, no analytics, no tracking, nothing about you. Results are cached in your own browser for 24 hours. Full policy.
