From fault to fix in under 4 minutes.
Three stages of AI reasoning. Each one runs automatically. The technician sees results in seconds, not minutes.
Setup takes under an hour
Most plants complete the full setup in a single session. No IT team. No integration work. Just documents you already have.
Work Order History Analysis
YAFEX scans your past work orders for the same machine and same equipment type. Each incident is scored by how closely the symptoms match the current fault.
Probable causes appear as cards with confidence percentages (e.g. “Bearing wear — 78% match”)
The technician confirms or rules out each cause in the conversation
If history resolves it, the answer is sourced from your own data — not generic knowledge
Manual Analysis
If work order history doesn't resolve it, YAFEX reads your uploaded manuals using semantic search — finding the most relevant sections, not just keyword matches.
Three possible causes generated with step-by-step checks
No confidence percentage — these are manual-based possibilities
Direct references to the specific manual section and page number
Deep AI Reasoning
When all standard causes are ruled out, YAFEX reasons from first principles. This becomes a free conversation the technician can keep going.
Considers unusual failure modes and environmental factors
Upstream equipment interactions — what else could be causing this?
The technician asks follow-up questions; YAFEX responds in context
Confirm the cause. YAFEX does the rest.

Frequently Asked Questions
YAFEX accepts PDF format for machine manuals. Most OEM manuals are already available as PDFs. If you have paper manuals they can be scanned to PDF before uploading.
You export your past work orders from your existing CMMS as a spreadsheet and import it into YAFEX using the Excel import feature. YAFEX maps the data automatically. This is optional — YAFEX works without work order history but improves significantly as history is added.
Yes. Every fault diagnosed and every resolution confirmed feeds back into YAFEX's understanding of your specific equipment. The system becomes more accurate and faster over time as it builds knowledge of your plant's specific failure patterns.
Yes. YAFEX is a multi-user platform. Multiple technicians can be diagnosing different faults simultaneously. All resolutions are captured and shared across the team automatically.
YAFEX has three diagnostic stages. If Stage 1 (work order history) and Stage 2 (manual analysis) do not resolve the fault, Stage 3 is a free-form AI reasoning conversation where your technician can discuss the fault in detail. In practice the vast majority of faults are resolved before Stage 3.
Yes. YAFEX is a cloud-based SaaS platform so an internet connection is required. It works on any device including smartphones and tablets so technicians can access it directly on the plant floor.
YAFEX does not require integration with your ERP or CMMS to function. It works standalone from day one. API integrations for popular CMMS platforms are on the roadmap.
