About DIAGIA
How much time — and how many parts — wasted on a diagnosis that blames the wrong cause? DIAGIA is the AI-powered automotive diagnostic assistant for repair professionals. Enter a fault code, describe the symptoms: in seconds, a clear resolution path with a confidence level based on the source. GOLD = RESOLVED CASES — When your fault matches cases already resolved in the DIAGIA base, you get a proven, highly reliable procedure. The right fix, not guesswork. SILVER = EXPERT AI ANALYSIS — With no direct match, the AI reasons through your fault (real-time web search) and guides you step by step, with measurement values. WHY GARAGES ADOPT IT • Fewer failed attempts, fewer parts replaced for nothing • A clear diagnosis in 30 seconds, on any make and engine • Hands-free mode: dictate, listen — without dropping your tools, even with gloves • Dashboard photo scan (automatic fault-code reading) • Pro PDF reports + one-tap client delivery • Multi-technician teams, full history, offline fault-code database WHO IS IT FOR? A professional tool reserved for clients with an active account (activation via your DIAGIA referrer). DIAGIA is a decision-support tool: every result must be confirmed by a measurement before any repair.
