THIS ISN'T CHATGPT
When people hear "AI," they often think of generic chatbots that make things up. ONI Suite is different.
WHY WE BUILT OUR OWN AI TOOLS
Generic AI Gets It Wrong
ChatGPT might tell you a 2010 Camaro has a Coyote engine. It doesn't understand the nuances of automotive tuning, OBD codes, or modification compatibility.
No Accountability
When a generic chatbot gives you bad advice, who's responsible? At ONI, our AI tools are backed by our reputation and our shop.
Not Built for Cars
General-purpose AI isn't designed to analyze engine sounds, interpret visual diagnostics, or understand real-world tuning scenarios.
THE ONI SUITE DIFFERENCE
Purpose-Built for Automotive
ONI Ear, Eyes, Pulse, Mind, and Voice are custom tools designed specifically for vehicle diagnostics and performance tuning.
Built by Enterprise Tech Veterans
Our founder has 28+ years in tech, leading connected vehicle projects at Toyota and building enterprise systems for Fortune 100 companies.
AI Enhances—Doesn't Replace—Experts
Our AI tools augment our team's expertise. Critical decisions still go through certified tuners with real hands-on experience.
MEET THE MIND BEHIND ONI SUITE
Rock Mutchler is a 28-year technology veteran who led connected vehicle technology for Toyota North America before founding ONI Customs. He's built enterprise systems for companies like Toyota, Activision (Call of Duty), PayPal, eBay, Facebook, Vanguard, Snapchat, Starbucks, and more.
If you've ever used a smartphone, played a video game, or shopped online—you've probably used systems Rock helped build. Now that same expertise powers the AI tools behind ONI Customs.
