Log everything, properly.
Every modification and service recorded with part numbers, costs, mileage, photos, and receipts. Organized by your car, searchable, and permanent — not a half-remembered note nobody can find in two years.

You know what it took. The research at midnight. The three attempts before it worked. The part you tracked down from a shop on the other side of the world. The moment it finally came together.
Six months later — or six years — that knowledge is gone. Buried in a forum thread nobody can find, reversed chronologically in a feed built to forget, scattered across notes apps that were never meant for this.
There's no dedicated place to document a car build over time, in order, the way it actually happened. Enthusiasts are doing this in Google Docs and Notion — not because those tools are good at it, but because nothing purpose-built exists yet.
G-Dimension is the logbook your car always deserved. Every decision committed to a permanent record — searchable, always there, exactly where you left it in five years. Even Carfax only captures half the picture: it knows your factory service history, but it knows nothing about your build.
"Here's my car. Here's everything I've done to it — in order, with receipts and photos."
What you get
Every modification and service recorded with part numbers, costs, mileage, photos, and receipts. Organized by your car, searchable, and permanent — not a half-remembered note nobody can find in two years.
A fully documented build commands a premium. Hand a buyer a complete record — every part, every cost, every photo, with receipts. That transparency proves the work and justifies your asking price.
Once the record is there, your timeline writes itself. Every modification in sequence from day one — a permanent visual story of the build that you'll actually want to share.
Questions
G-Dimension is a digital build journal and maintenance logbook for car enthusiasts. It keeps every modification, part, service, receipt, and photo for your car in one permanent, searchable place — organized by car and in the order it actually happened. Think of it as the dedicated logbook your car always deserved, instead of scattered forum threads, notes apps, and a social feed built to forget.
Instagram and forums are built for conversation and reverse-chronological feeds, not for keeping a permanent, ordered record of one car. G-Dimension organizes everything by your car and in the sequence it happened, so your full build history stays searchable and intact for years instead of getting buried. It is a structured logbook, not a social feed.
Yes. G-Dimension is built around a garage, so you can keep a separate, complete build journal for every car you own. Each modification, service record, part, and timeline entry stays tied to the specific car it belongs to.
G-Dimension is a mobile-first web app that runs in any browser and installs to your phone's home screen like a native app. There is nothing to download from an app store — you can start on your phone or computer today at gdimension.app.
Yes. G-Dimension is free to join and use during early access. You can create an account, add your car, and start documenting your build at no cost.
Yes. Every build gets a clean public profile at gdimension.app/builds/your-username that shows your car, specs, modifications, and timeline. You control what is public, and you can share the link anywhere.
Your data is private by default and you choose exactly what appears on your public profile. Sensitive details like receipts, purchase price, VIN, license plate, and documents are always kept private and never shown publicly.
Yes. G-Dimension can generate a complete build sheet PDF of your car — every modification, part, and cost with photos — to hand to a buyer or keep for your records. Your documentation belongs to you.
You can record modifications with part numbers and specs, maintenance and service history, detailing sessions, parts you own, receipts, costs, mileage, photos, and free-form timeline entries. Everything is organized by car and grouped into a build sheet across Power, Chassis, Exterior, and Interior.
A fully documented build helps justify your asking price. Handing a buyer a complete record — every part, every cost, every photo, with receipts — proves the work was done and builds trust that a pile of unlabeled photos cannot.
