CheckEngine

What it does

CheckEngine helps you understand a car before you buy it. Paste a VIN or upload photos to get vehicle details, risks, possible problems, repair estimates and market context. Then track the car's real costs, repairs and profit in one place. Built for car buyers, importers, flippers and independent dealers.

Track cars, costs and real profit. NBU currency conversion, VIN check and decoder, car recognition from a photo and AI fault diagnostics.

A digital assistant for tracking and analysing car sales. Every car, every cost and the real profit — in one place, without endless spreadsheets and notes in a pad. You add the car and enter each cost in the currency you actually paid in. CheckEngine converts everything at National Bank of Ukraine rates, works out the cost price and the profit, and shows how much money is tied up and how much you have already made. No modules you will never open — only what you will use every day. In stock, in transit and sold are separate sections, so you always know what is on the lot, what is still on its way, and what has already made money. Enter every cost in its own currency: the auction in dollars,…from checkengine.website

  CarCheck – Car Buying Checklist App2024 · usefulchecklists.com · ▲164

  Hey HN! A few years ago my brother in-law was looking to purchase his first car. He was struggling to know what to look for when going to car dealerships and felt quite overwhelmed with the financial and practical decisions required. Not that I have any particular expertise with cars or the engineering involved, but through my own experiences purchasing cars and owning them I gave him some advice and "tips". As anyone would. Things only morphed from there, I spent the next couple of years in my spare time learning to code, researching, and developing CarCheck. It's been a journey! Hindsight…

  Hi everyone, we built a vehicle history report offering that I wanted to share and get some feedback on. It collects data from over 1,200 sources across North America and compiles to a single clean report like Carfax and Autocheck. We would really value any feedback from anyone currently in the researching/buying/selling phase - what pieces of information are / were essential in your recent purchases? Thank you!

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
