How it all started

The idea behind CarAIDiag was simple: if AI can recognize faces and voices, why can’t it understand the language of an engine?

We decided to combine ELM327 with artificial intelligence to read how the engine behaves, detect hidden issues and translate complex error codes into clear, human-readable recommendations. That’s how smart diagnostics that know your car better than you do were born.

CarAIDiag is more than diagnostics. It’s a co-pilot that knows about potential issues before you hear the warning beep.
