Unit Balance: Chiller Comparison by PDF

variant42.org Observed source

Editorial interest 78/100 Selection signal · not a rating of the site

A Russian-language AI service extracts HVAC specifications from supplier PDFs and compares up to five offers against a technical brief.

Landing page captured for the 2026-09-14 issue.

Field notes

The workflow accepts up to five supplier PDFs, extracts 18 stated characteristics, and compares them with tolerances entered in the technical brief. The page demonstrates supplier scores of 92%, 80%, and 58%, while missing values appear as «нет данных». It also separates extraction from the claimed decision layer: AI reads the documents, but a deterministic engine applies the comparison rules and produces the color-coded result and downloadable PDF report.
