VIN decoder for Chrome. Check NHTSA safety ratings, open recalls & real market value on any used car listing. Free 5 scans/month. CarWise is a free VIN decoder and car buying co-pilot for Chrome. It runs inside any used car listing and gives you the full picture on any vehicle before you make an offer — safety ratings, open recalls, real market value, and factory specs, all without leaving the page. Stop overpaying for used cars. Stop missing open recalls. Start buying with confidence. ───────────────────────────────────── WHAT CARWISE DOES ───────────────────────────────────── ✅ VIN DECODER Decode any 17-character VIN instantly using NHTSA's official database. See make, model, trim, engine size, body style, drivetrain, and factory specifications — the exact vehicle you're looking at, not an estimate. ✅ NHTSA SAFETY RATINGS See the official US government crash test ratings for the vehicle: overall safety score, frontal crash, side crash, and rollover ratings. Pulled directly from NHTSA — the same data dealers have access to. ✅ OPEN RECALL CHECKER Instantly check whether the vehicle has any open NHTSA safety recalls. See the recall description, affected components, and whether the remedy is available. This takes 30 seconds. Not checking is how buyers get stuck with unsafe cars. ✅ REAL MARKET VALUE ESTIMATOR Get a data-driven market value range — private party, trade-in, and dealer retail — calibrated per make using real depreciation curves and adjusted for mileage. Know what the car is actually worth before you negotiate. ✅ EPA FUEL ECONOMY See city, highway, and combined MPG for the exact trim and engine you're considering. Understand the real cost of ownership before you commit. ✅ F&I PROTECTION GUIDE Dealer finance and insurance (F&I) offices add thousands of dollars in add-ons at signing. CarWise explains which ones are worth it — extended warranties, GAP insurance, paint protection, and tire-and-wheel coverage — and which to decline. Save $1,000–$3,000 at the dealership. ✅ BUYER SHIELD CHECKLIST Eight-point pre-purchase checklist: VIN verified, recalls clear, price in range, safety rated, history reviewed, fuel economy checked, F&I protection planned, financing pre-approved. Walk into any deal knowing you've covered every angle. ✅ PRICE DECODER See estimated dealer invoice, market average, and a fair offer range for any vehicle. Anchor your negotiation on data, not the sticker price. ✅ LOAN & LEASE CALCULATORS Built-in auto loan calculator, lease calculator, and buy-vs-lease comparison. See your actual monthly payment before you sit down with the finance manager. ───────────────────────────────────── WORKS ON ALL MAJOR CAR LISTING SITES ───────────────────────────────────── CarWise activates automatically on dealer sites, certified pre-owned platforms, and private seller marketplaces — wherever used cars are listed online.

VIN lookups are processed through our secure server and are not linked to your identity unless you create an account. We do not inject ads, track your activity across sites, or share data with third parties. ───────────────────────────────────── FREQUENTLY ASKED QUESTIONS ───────────────────────────────────── Is CarWise really free? Yes. The free plan includes 5 full VIN scans per month — no credit card required. Each scan includes safety ratings, recalls, market value, and fuel economy. How does the VIN decoder work? CarWise extracts the VIN from the listing page and queries NHTSA's Vehicle Product Information Catalog (vPIC) API to return factory specifications. It's the same database used by government agencies and auto industry professionals. Does CarWise check for recalls? Yes. CarWise queries NHTSA's recall database and returns all open safety recalls associated with the VIN, including the affected component and whether the remedy is currently available. What is a market value estimate? The market value estimate uses manufacturer-specific depreciation curves, adjusted for mileage and condition, to give you a realistic private party, trade-in, and dealer retail range. It is not a Carfax or AutoCheck report, but it gives you a solid data-anchored baseline before you negotiate. Does CarWise work on private seller listings? Yes. CarWise activates on Facebook Marketplace vehicle listings and Craigslist auto posts. You can also manually enter any VIN to run a full check on any vehicle regardless of where it's listed. What is the F&I protection guide? F&I (Finance & Insurance) is the dealership's finance office, where buyers are often pressured to add products like extended warranties, GAP insurance, and paint protection. CarWise explains each product — what it covers, what it costs, and whether it's worth buying — so you can make an informed decision at the table. ───────────────────────────────────── ABOUT EXTENSIONS MARKET ───────────────────────────────────── CarWise is built by Extensions Market (extensionsmarket.com), an independent software developer building browser extensions and Shopify apps that help people make better financial decisions.
