Know that the writing is theirs.
Students write in a locked box. You see how every paper was written, and you get a signed receipt that shows it has not been changed since. Free for one class.
Three minutes to try it: no sign-up, no email, nothing to install. Ready for your class? Create a free account.
How it works
You set it up
Type your assignment, choose how strict it is, and get a code for each student. A few minutes, with a preview of what students will see.
Students write
They open the address and type their code. The page goes full screen and offers only a text box. Pasting from outside is refused, and leaving the page is noted.
You see how it was written
You watch the paper appear back at any speed, with plain notes on anything worth a conversation. The finished paper comes with a signed receipt anyone can check.
What is recorded
- What was typed, and when.
- Whether text was typed, dictated, or pasted into the box.
- When the page lost focus or left full screen.
Nothing else: no screen, no camera, no microphone, no other windows. Students are told this before they start.
What it is not
- It does not guess whether text came from an AI.
- It does not punish anyone. Leaving the page is only noted; a student can explain it.
- It does not replace your judgment. It gives you something real to talk about.
What it costs
Free for one class: up to 25 students and three assignments a term. Teacher plans add more classes, the full replay of every paper, and use inside your school's learning system. Schools can add shared sign-in and admin tools. Students never pay.
