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.
