How it works
Four steps from beginner to builder
Choose Your Build
Pick an engine, dirt bike, or vehicle project — from a starter 85cc bike to a V10.
Drag & Drop Parts
Snap pistons, carburetors, suspension, and wiring into place piece by piece.
Learn How Each Part Works
Every component comes with plain-English explanations of what it does and why it matters.
Complete Builds & Earn Badges
Finish builds, run simulations, level up, and collect achievement badges.
What's inside
A complete virtual shop class
Drag & Drop Builder
Assemble engines, dirt bikes, and vehicles part by part with snapping placement and instant feedback.
AI Build Coach
A built-in assistant guides your next step, explains mistakes, and keeps you moving.
Part Encyclopedia
Tutorials and part-level explanations: what it does, how it works, why it matters.
Diagnostic Lab
Take real repair work orders — scan codes, test circuits, and fix faults like a shop tech.
Build Challenges
Timed and accuracy challenges with XP, streaks, and a leaderboard.
Premium Build Library
Engines, dirt bikes, dream cars, turbo and suspension setups — all unlocked with your plan.
From Digital Builds to Real Repairs

Why this app exists
Built by a father & son,
for every builder.
Darrance & Aiden Tezino
Founders · father & son
We didn't just build an app — we built time together. YouBuildItAI started as an intentional father-son project: a way to share a love of engineering and spark STEM creativity. But it grew into something bigger — a platform for every creative mind who wants to build. Every subscription still goes toward my son Aiden's early college fund, and every subscriber joins a community that believes engineering is for everyone. When you subscribe, you're not feeding a corporation — you're helping builders everywhere create, one build at a time.

Aiden's college fund
Every subscription directly supports an early college fund for a young builder’s future — and fuels the platform for all.
