The challenge

Buying a used car in Croatia is a minefield  scattered Njuškalo listings, hidden odometer rollbacks, model-specific engine and gearbox faults, and inflated prices, with no easy way to judge whether a listing is a good buy. 

A mechanical inspection costs money and time per car, and generic online buying guides are written for a whole market in general — not the exact engine and gearbox combination sitting in a specific Njuškalo listing right now. By the time an inspection is booked, the car is often already sold.

The approach

01

Paste

Paste any Njuškalo listing URL — no account, no signup. Free for buyers across Croatia.

02

Analyse

The AI reasons about the exact engine and gearbox, using knowledge of what actually breaks on these cars in Croatia.

03

Verdict

A 0–100 confidence score, risk flags, repair-cost estimates and a fair-price delta against the Croatian market.

04

Act

A pre-purchase checklist, seller questions and a negotiation plan — exportable as a shareable PDF in EN or HR.

03

Tech decisions

01Next.js + React

Paste → analyse → verdict needed to feel instant and app-like, with no full-page reloads between steps — every extra second between pasting a link and seeing a result is a buyer who gives up and closes the tab.

02Server-side AI analysis

The reasoning over a pasted listing's text runs server-side, close to where the listing content is fetched and parsed — keeping the model calls and scraped data off the client also means the analysis logic can't be inspected or gamed from the browser.

PDF

Downloadable report (EN · HR)

Buyers can bring the analysis to a negotiation or an in-person inspection, not just read it once and lose it.

AutoGuru is an AI research assistant, not a mechanical inspection or professional advice. Analyses can be incomplete or wrong — always confirm critical findings with an in-person check by a qualified mechanic before you buy.
