15,000+ curated standards chunks. One ground truth.
MetLibrary is the difference between an AI that guesses and one that knows. Every response cites the source standard and clause, so you always know exactly where the information comes from.
- 15,000+ semantically indexed chunks for precise retrieval
- Every answer includes source document and clause reference (APA format)
- Covers ISO, NIST, NCSLI, A2LA, JCGM, ASQ CCT, VIM, and more
- Core standards (ISO 17025, GUM, CCT BoK) available to all plans
- Advanced corpus (NCSLI RP, A2LA, Z540.3, JCGM 106) on Professional+
