An Honest Take

Because checking a VIN before buying a used car shouldn't cost $40. Most people can't decode a 17-character VIN by hand, and the paid services like CarFax charge real money for information that's largely based on public data. NHTSA recalls, safety complaints, manufacturer specs — that's all free if you know where to look and how to look. Most people don't. So we built something that does the looking for you.

VIN decoding — year, make, model, engine, transmission — is rock solid. VINs are standardized by NHTSA, so the first 17 characters always mean the same thing. That part is math, not guesswork. But the history side is different. That information comes from AI searching public databases — it can find NHTSA complaints, open recalls, safety ratings, and manufacturer bulletins. What it can't access is insurance claim history, private service records, or auction data the way CarFax and AutoCheck can through their exclusive data partnerships.

It can't tell you about unreported accidents. It can't catch odometer rollbacks that weren't flagged in a public system. It can't find flood damage or salvage history that was never entered into public records. If you're about to spend thousands of dollars on a used car, a paid report is still worth it for the most complete picture. This tool is a first pass, not a final answer — and we'd rather tell you that upfront than let you think otherwise.

Use VINorNOT first as a free sanity check. If nothing flags — no open recalls, no pattern of complaints, and the VIN decodes to exactly what the seller claims — you might be fine. But if something looks off — active recalls, a history of the same complaint from other owners, or the VIN doesn't match what you were told about the year or engine — then invest in a full report before spending real money. Think of it like checking the weather before deciding if you need a jacket. Sometimes the free answer is enough. Sometimes you need the full forecast.

Zero servers. Your VIN goes directly from your phone to Groq's AI and back. We don't store VINs, we don't build a database of what vehicles you're looking at, and we literally cannot see what you're checking. There's no account, no login, no tracking. You type a VIN, you get results, and that's the end of it.
