How Keyi helps
Venues and multiple campuses
Schedule venues by capacity (even by time), assign rooms, and leave travel time for teachers moving between campuses.
Cover and lesson counts
Cover suggestions use the actual day's timetable; taught and missed lessons are counted automatically.
Case study
An international school's G9 options: same 19 sections, largest class from 33 down to 26
We re-ran sectioning on the school's real choice sheet (89 students, 4 blocks): every student kept every choice; with the same 19 sections, physics went from 32/18/16 to 22/22/22 and the class-size standard deviation dropped from 6.0 to 2.3, in about 30 seconds.

Can we import our existing data?
Yes. One Excel file imports classes, teachers, subjects, hours, combined classes and blocked times, and enables the recommended rule pack.
