Worth noticing
Its 165 hand-labeled cases are described as a regression check, not an accuracy estimate.

Field notes

The extension reads table headers and sample values, asks a model narrow questions about their meaning, and applies a color scale while preserving text contrast. Its documented checks include 21 test pages, but the site cautions that the 165 hand-labeled columns are a regression check rather than an accuracy estimate. Installation currently involves Chrome’s “Load unpacked” flow; the page says a Chrome Web Store listing is coming.
