- Worth noticing
- It says redacted downloads contain page images with black boxes painted into the pixels, rather than text concealed beneath removable overlays.
Field notes
The stated workflow lets users inspect each highlighted match, remove false positives, add terms, or draw their own boxes before downloading. For scans, the page says recognition runs locally in 30 languages and can straighten tilted pages. It describes the output as page images with redactions painted into the pixels; an optional model is said to download once for offline use.
