Chrome extension layering feedback, leveling and lesson tools onto Google Docs and the browser.
What it is good at
The free individual tier is unusually generous and needs no institutional purchase, so one instructor can adopt it without a procurement cycle. Its writing-history replay shows how a draft was built, supporting process-based integrity conversations. Works inside Google Docs where students already write.
Use it for
Generating targeted, rubric-aligned inline feedback on a stack of essay drafts to cut turnaround from two weeks to days. Replaying a document's history to open a conversation about a draft that appeared in one paste.
Where it falls short
K-12 by design, so rubrics and reading levels assume grade bands rather than college outcomes. The writing-history replay is suggestive, not probative — a student who drafts elsewhere and pastes is not committing misconduct, and treating it as evidence recreates the detector problem. As a Chrome extension it can see document contents; get a privacy review before asking students to install it.
