Your best technician's
expertise, scaled to every tech
Dex is an AI copilot for the skilled trades. We codify your senior technicians' diagnostic and repair sequences into structured decision trees so junior techs can follow expert-level processes in the field — without constant escalation.
How it works
Senior expertise, delivered step-by-step to every technician on your team.
Capture expert workflows
We work with your senior techs to codify their diagnostic sequences, repair processes, and best practices into structured decision trees — paired with OEM documentation.
Guide techs in the field
Technicians follow step-by-step checklists and voice AI through inspections, measurements, and repairs. The app adapts the path based on what they find at each step.
