Greatbook is an offline-first gradebook for teachers, with reports, standards, trends, rosters, and class records kept in files the teacher owns.

Landing page captured for the 2026-09-13 issue.

Field notes

Greatbook organizes students by row and assignments by column, then derives course grades, standards views, report cards, and trends from entered scores. Its records model is deliberately local: the page says each score remains in a file the teacher owns, with the same behavior when Wi-Fi is off. The feature list also includes Google Classroom imports, Common Core and NGSS standards, and optional per-class behavior and contact logs. Windows, macOS, and Chromebook use are described.
