TripValidator

Before you pay the booking

TripValidator analyses a holiday rental offered by a private owner from the listing, the conversation with the owner and whatever details they gave: phone, IBAN, website, photos, tax ID, address and tourist licence. In about two minutes it returns a risk score from 0 to 100, every signal explained and what to check before paying.

An auditable verdict

The risk comes from a rules engine with 18 detectors built on the fraud patterns published by the Spanish police, the Guardia Civil, consumer group OCU and the platforms: foreign IBAN, payment outside the platform, too-good-to-be-true prices, fake tourist licences or websites impersonating Airbnb. Official validators check the IBAN (ISO 13616), Spanish DNI, NIE and CIF, phone numbering and the tourist-licence format of each region. A critical signal keeps the risk very high even when other signals look good.

AI and shared history

In the full report, Anthropic's Claude reads the text, the conversation and the photos looking for what rules miss; it can add signals and raise the risk, never lower it. Every phone, IBAN, email, website, tax ID, address and photo analysed leaves a fingerprint: if it already showed up in risky offers or in verified reports from other travellers, the risk goes up. The history can be looked up for free and only shows aggregate counters.

Pricing and privacy

The preview is free; a full report costs €9.99 (€8.33 per check in the pack of 3 and €6.99 in the pack of 10), with no subscription and no expiry, paid through Stripe.
