Watch them think.
See how every essay was written.
An AI tutor that makes students think, and a record of how the work actually got written.
Most high schools start before 8am, and research links that to chronic sleep loss in teenagers.
Written by the student, keystroke by keystroke.
A student essay being typed live. The writer replaces a first attempt with a more considered sentence, and the authenticity score rises to 94.

Built for Every Educator
We're educators ourselves, with over a decade building educational technology alongside NYC's Board of Education. We built Limudi for teachers like us.
Two essays. Same assignment. Same grade.
Nothing in a submissions list tells these two apart. Here is what happened while they were being written.

of students use AI for homework. Teachers can't tell.
Pew Research, 2025AI detectors don't work. A Stanford study found they flag ESL students as cheaters up to 61% of the time. Most teachers have given up on them.
Banning AI didn't work either. Students use it anyway, and they probably should. It's the world they're walking into.
The real question is whether they did the thinking.
You create the assignment
Type in a topic. The AI builds a full assignment with learning objectives, a grading rubric, and comprehension questions. Tweak what you want, publish it, and your students can start working.
Students do the work
Students write in a workspace that tracks every keystroke, pause, and revision. When they get stuck, an AI tutor asks them questions instead of giving answers. You see the whole process, every draft along the way.
You open a submission
You can see the whole writing process. How many sessions, how long they spent, what they pasted, where they paused. An authenticity score tells you if the work is genuine. You can even replay how the essay was written, keystroke by keystroke.
You grade the class
The AI suggests a grade for each submission with its reasoning, broken down by your rubric. Accept it, adjust it, or ignore it. Your dashboard shows the whole class at a glance: who submitted, who's struggling, and what needs attention.
The Science Behind Limudi
Peer-reviewed research confirms what Limudi was built to address: uncritical AI use erodes the thinking skills students need most.
Of the difference in critical thinking ability between students is explained by how often they use AI
