The AI metrology tutor
that knows the standards.
MetTutor is an AI-powered learning assistant built on 983 authoritative metrology standards — delivering cited, standards-grounded answers for calibration professionals, students, lab managers, and educators. The new v2.0 workspace adds document generation, the ContextPanel, and Saved Chats on every Metrologist seat and above.
Not general AI. MetTutor.
General-purpose AI tools guess at metrology. MetTutor is built on the documents the industry actually runs on — and cites every answer.
Ask it anything. It knows metrology.
Every MetTutor query runs through one of four focused modes — each tuned to produce the right type of answer for your goal.
Answers from standards, not the internet.
MetLibrary is MetTutor’s dedicated RAG knowledge base — 983 metrology documents indexed across 26,018 semantic chunks, curated and version-controlled so every answer comes from a recognized source.
- ISO/IEC 17025:2017 — full clause library
- JCGM 100:2008 GUM · NIST TN 1297 — full uncertainty framework
