Why you need this

Three problems every metrology organization faces

If any of these sound familiar, MetTutor was built for you.

🎯
Your team’s knowledge is inconsistent
One technician interprets ISO 17025 §7.6 one way, another interprets it differently. Training is expensive, sporadic, and hard to track. When the auditor arrives, you’re scrambling for competence evidence.
MetTutor → Consistent, cited answers + training records
⚠️
General AI can’t be trusted for standards work
ChatGPT confidently cites clause numbers that don’t exist. You can’t risk compliance decisions on an AI that fabricates requirements. Your quality system demands traceability — including knowledge traceability.
MetTutor → RAG-grounded, zero hallucinated clauses
📊
Calculations take too long
Uncertainty budgets, TUR analysis, Gage R&R, guard banding — the calculations that consume hours of a metrologist’s week. Your team does them manually, inconsistently, or not at all.
MetTutor → GUM budgets, Gage R&R, decision rules in minutes

“I tested MetTutor against two other AI tools with the same ISO 17025 §7.6 question. The others fabricated clause numbers. MetTutor cited §7.6.1, §7.6.3, and the GUM reference correctly. That’s the difference.”
MH
Technical Director
Electrical calibration laboratory
“My CCT exam prep was transformed. The spaced repetition engine surfaced exactly the topics I needed to review, exactly when I needed them. I passed on the first attempt.”
JR
Calibration Technician
Dimensional laboratory
“The Training Activity Report gave our auditor exactly what they needed for §6.2.2 competence evidence. No more scrambling for documentation before assessments.”
