The intelligent car marketplace

Tell Nitro what you're after. It builds a Stack of cars that fit. You swipe through them and keep the ones you like.

CarStack

Start here

Four moves from "I need a car" to keys in your hand.

Ask Nitro, out loud or in chat

01

Budget, seats, how far you'll drive, the stuff you'd tell a friend. Type it or say it. Nitro answers any car question along the way.

Get your Stack

02

Nitro builds a Stack of cars that fit what you said. It keeps watching the market, and a badge tells you when new cars land in it.

Swipe to your shortlist

03

One car at a time, full screen. Right to like, left to pass. Ten minutes and your shortlist is done.

Meet somewhere safe

04

Deal Mode suggests public meeting spots, saves the one you both pick, and confirms you've each arrived before the deal starts.

What's inside

One AI. Every step of the deal.

From the first question to the signed paperwork.

Nitro · voice or chat

Just say what you want.

Talk to it or type to it. “Family SUV under $25k, third row, low miles.” Nitro turns that into a Stack, explains each pick, and answers anything else, from what a fair price is to what to check at the meetup.

Stacks · built for you

Your search, saved and alive.

Every conversation, filter, or photo you give Nitro becomes a Stack. It keeps watching the market after you close the app and badges you when new cars land in it.

The deck · swipe to decide

Narrow it down with your thumb.

Open a Stack and the cars come one at a time. Right to like, left to pass, tap for the full listing. Everything you liked waits in one shortlist.

Sell with AI

List a car in three photos.

Nitro drafts the description, prices it against live market data, and lifts your car off its background so the listing looks showroom-clean.

Deal Mode · Laps

Meet safely. See it move first.

A 30-second Lap shows the car running before you ever text. Deal Mode suggests public meeting spots, saves the one you agree on, confirms you've both arrived, and walks the deal to a signed bill of sale.

The whole market, one deck
