Snap pistons, carburetors, suspension, and wiring into place piece by piece.

03

Learn How Each Part Works

Every component comes with plain-English explanations of what it does and why it matters.

04

Complete Builds & Earn Badges

Finish builds, run simulations, level up, and collect achievement badges.

Why YouBuildItAI works

Not a game. Not a textbook. Real shop skills.

Most build apps let you pick colors and rims. YouBuildItAI makes you assemble the machine yourself, understand every part, and diagnose what's wrong when it doesn't run.

A safe place to mess up

Drop a piston, wire something backwards, blow a fuse — then undo it and try again. No broken parts, no wasted money.

Learning built into every part

Unlike car configurator games, every component teaches you what it actually does in a real machine.

Real diagnostics, not just assembly

Run simulations, read live telemetry, and troubleshoot faults with scanner and multimeter tools — skills real shops use.

Coaching, not just clicking

The AI Build Coach encourages you, suggests the next step, and explains mistakes without judgment.

Who this is for

Built for the next generation of builders

High school students

Explore automotive tech before committing to a trade program — and show up to shop class ahead of everyone.

Shop class beginners

Practice assembly and diagnostics at home so real tools feel familiar, not intimidating.

Young riders & mechanics

Learn how your dirt bike or first car actually works so you can maintain and upgrade it yourself.

Parents & mentors: every subscription supports a distraction-free learning environment with no ads and no chat with strangers — just building and learning.

Why this app exists

Built by a Father & Son, With Intention

Darrance and Aiden Tezino — father and son creators of YouBuildItAI

We didn't just build an app — we built time together. YouBuildItAI is an intentional father-son project: a way to share a love of engineering, spark STEM creativity, and put every subscription toward my son Aiden's early college fund. When you subscribe, you're not feeding a corporation — you're helping a family build a future, one build at a time.
