Field notes
The page describes progress in roughly ten areas, including articles, verb agreement, and questions, with a rate per 1,000 words for each. Its four labels—New, Learning, Strong, and Fading—distinguish developing skills from ones that may need another look. The site says text stays inside the extension, with only counts and settings saved in the browser; it also notes that Google Docs support depends on the browser.
