Pricing

$10 a month, for the family

One price for the household, however many children are in it. the first month free, and you can pay for a year up front instead if you would rather.

Billing is not switched on yet. Signing up today costs nothing and takes no card, and nobody is charged without being asked first.

A household

$10 a month. Every child you teach, every subject, every worksheet. There is no per-child seat and there is nothing to negotiate: you sign yourself up and you are grading in a couple of minutes.

the first month free, which is long enough to photograph a real stack rather than a demo one. Paying for a year up front is available — ask, and we will set it up.

A school

A school is not a family with more children in it. Classes belong to a school year, teachers and assistants are assigned per class, somebody has to sign a data processing agreement, and the bill goes to the office rather than to a teacher's own card. That is a quote, not a checkout.

Tell us how many classes and who needs to sign what, and we will price it.

What counts as usage

Photographs read. Nothing is metered per child, per class or per subject, and nothing here charges more because a worksheet was long. A page that could not be read is not charged for either — it was not graded, so it is not usage.

When billing starts

You will be asked for a card before anything is taken. the first month free still applies from the day you are asked, not from the day you signed up, so nobody loses a trial to the wait. You can stop at any point and keep every export you have already downloaded.
