CASE diagnostics: DTC & AI

CASE is a working case log for diagnostic technicians and auto electricians. One file per vehicle — VIN, symptoms, DTC codes, component readings, and every check you ran — in one place, not scattered across a notebook or a forum thread. Three AI modes powered by Google Gemini, each one already knows your case: — Case Copilot: ask a quick question, no need to repeat context — Deep Research: a multi-step look across external sources, with references — Guided Diagnosis: one precise question at a time, ruling theories in or out Log DTC codes manually, by scan, or with AI decode right in the card. Voice notes on diagnostic steps. Search similar cases in your own history. Generate a client-ready PDF report in seconds — pick the sections you need. AI output is advisory only and doesn't replace professional judgment or safety procedures. Available on iPhone. Free, Pro and Max plans — details in the app. Terms of Use (Apple Standard EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
