Description
Stop paying $150+ for dealer diagnostics. Otto is an AI mechanic trained on your car's actual manual — not generic internet advice. Get accurate, model-specific answers in seconds.
NEW: OBD-II LIVE DIAGNOSTICS
Connect any Bluetooth OBD-II adapter to your car. Otto reads engine codes (DTCs), shows live sensor data in a real-time dashboard, and gives you AI-powered diagnosis — explaining what's wrong and how to fix it, with citations from your vehicle's service manual.
30+ SUPPORTED BRANDS — GAS, HYBRID & ELECTRIC
Mercedes-Benz, BMW, Audi, Toyota, Honda, Ford, Nissan, Chevrolet, Hyundai, Kia, Volkswagen, Tesla, Rivian, Subaru, Mazda, and more. Gas, hybrid, and electric vehicles all supported. Each vehicle gets its own AI agent trained on that model's actual owner manual and technical specs.
ASK LIKE YOU'D ASK A MECHANIC
"What oil does my 2020 Camry take?" "Why is my check engine light on?" "How do I reset the service indicator on my RAV4?" Otto understands your exact year, make, and model - and answers with manual references, not guesswork.
SAVE MONEY ON REPAIRS
Skip the $150 dealer diagnostic fee. Otto reads warning lights, explains error codes, and tells you what's urgent vs. what can wait — so you walk into the shop informed, not guessing.
