Built for teachers who would rather spend their time teaching than typing scores into a spreadsheet at 11pm.

YOUR WHOLE CLASS IN ONE PLACE
Set up a class in under a minute, add your students, and you are ready for Monday. Grades, attendance, homework checks and daily notes all live together — no more juggling a paper attendance register, a spreadsheet and a stack of sticky notes.

A CLASS JOURNAL YOU CAN ACTUALLY KEEP UP WITH
Open a class and you land straight in the journal. Mark who is present, late or absent. Record who knew the lesson and who did not. Jot a quick note while it is still fresh. Taking attendance and recording grades takes seconds, and it happens while you are still standing at the front of the room.

SEND GRADE REPORTS TO PARENTS WITH ONE LINK
Parents do not need to download anything. Send them a single link and they can look up their own child's grades in any browser. No accounts for them to forget, no app to install, no phone calls asking how their child is doing. The link shows grades only — your private notes never appear on it.

EXPORT GRADES WITHOUT RETYPING
End of term should not cost you a weekend. Export your gradebook straight to Excel and fill in your school's template automatically. Generate a PDF grade report or a printable class roster. The numbers you already entered are the numbers that come out.

WORKS WITHOUT INTERNET
School wifi always drops out at the worst moment. Chalkbook is an offline gradebook: everything is stored on your device first, so it opens instantly and works the same in a basement classroom as it does at your desk. Sync when you are ready.

A NOTE ON BACKUP
