Protecting academic integrity in the age of AI.

Real work. Real learning. Real results.

CheatProof.
“Block the cheat sites. Protect the learning.”

A new category of cheat sites is spreading around the world, letting students complete any homework without learning the material. CheatProof blocks these sites before they can impact your students’ learning outcomes.

“Prove you wrote it.”

A polished essay no longer proves a student understands it, or even wrote it. EssayProof asks each student three questions about their own work, so teachers can see whether the thinking on the page is really theirs.

“Prove your platform measures real learning.”

For EdTech companies and education publishers, schools increasingly want assurance that the platforms and digital textbooks they invest in can't be exploited by AI tools and cheat sites.
PlatformProof tests your products against the same AI tools and cheating methods students actually use, identifies vulnerabilities, helps you close the gaps and certifies your platform as AI-Proof.

EssayProof.

Prove you wrote it.

AI writing keeps getting better
Every new model writes more like a real student. Spotting AI from the text alone is a race no one can win.
Detectors are unreliable
AI detection software guesses from patterns. It misses AI-written work and flags honest students with false positives.
Understanding can’t be outsourced
Whatever wrote the essay, the student still has to understand it. That weakness never goes away, and it’s where EssayProof looks.

EssayProof automatically generates questions from the student’s own essay, aimed straight at their understanding of what they wrote. Each is multiple choice with four options and just 20 seconds to answer: plenty for someone who knows their own work, not enough to ask an AI tool. A student who wrote the essay can explain it. A student who didn’t, can’t.

  1. 1The student submits their essay.
  2. 2They answer three timed questions generated from that essay.
  3. 3You see whether they understand it, and whether the work is really theirs.
