See how students build their spreadsheets, not only what they hand in.

Students work in the sheet
The assignment opens in a spreadsheet in the browser.
STEP 2
Every step is recorded
Every formula typed, every paste, every minute.
STEP 3

I'm an instructor
Four sample classes with student work already in them. Open a submission to see its report, replay and flags.
You can also build your own: upload an Excel workbook you already use, or describe an assignment.
I'm a student
Join a class and do an assignment the way students do: the sheet, the AI assistant, the submit step.
Then switch to the instructor view to see how your work was recorded.
- No sign-in, no email, no account.
- A private copy: nothing you do is seen by anyone else.
- Five minutes of clicking around is enough to see the whole thing.
- The workspace is a cookie in this browser, removed after thirty days of not being opened.
