For every Factory Five builder

Don't build alone. Your pit crew, in your pocket.

A step-by-step build guide for your Factory Five kit, an AI assistant grounded in your assembly manual, and a maintenance log that travels with the car for years after the first start. From kit to driveway to next owner — one companion the whole way.

The demo is a Mk5. The framework — guided steps, AI grounded in your manual, smart maintenance — extends to every car in the lineup.

The hard parts, handled

Built for where it gets hard.

“Am I in over my head?”

Every step is a checklist you tick off as you go. Set it down for a month, come back, and you know exactly where you left off.

“What if I get it wrong?”

Exact torque values, the right hardware, and the common mistakes — right on the step. The numbers that matter are never buried.

“Stuck, and no one to ask?”

The assistant answers in seconds, grounded in your actual manual with the page cited. No waiting until Monday.

Beyond the build

It doesn't end at first start.

The build is a year or two. Owning the car is the next decade.

Maintenance, tailored to your build

The app knows what engine you ordered, so reminders fit your car — not a generic average. By the mile and by the month.

A service log you'll actually keep

Every oil change, grease job, and torque check — with date, mileage, cost, and photos. The whole history, not a guess.

A history report when you sell

One PDF: how it was built, everything serviced, every mile. Answers the buyer's first question for you. Worth real money at resale.

How it works

From the box on your driveway to ten years later.

  1. Tell us about your build

    Snap a photo of your Factory Five order confirmation and the app reads it for you — engine package, transmission, suspension, brakes. Or fill it in manually. The whole rest of the guide tailors itself to your specific kit.

  2. Follow the guided steps

    Open a step on your phone in the garage. Tick off sub-steps as you finish them. Drop notes for future-you. Snap photos of the work. Every step links cleanly to the next.

  3. Ask the AI when you're stuck

    Tap the Pit Crew pill, type your question. The assistant pulls the relevant pages from your manual and answers in plain English — citing where it found each fact.

  4. Log every mile after the first start

    Once the build is done, the same app tracks your odometer and every service event. It tells you what's due based on your specific engine and how you drive. The whole history transfers if you ever sell.
