Thirteen ways we
stump the AI.
CatchGPT uses thirteen question patterns built on one principle: your students have the reading, ChatGPT doesn't. Four source-exclusive modes make questions fundamentally unanswerable without your packet. Click any to see how.
Hard for AI.
Fair for kids.
Stumping AI is easy. Stumping AI without tricking your students is the part we get right.
1
All four answers look alike
Wrong answers match the right one in length, grammar, and tone. The longest answer isn't always right. The most-confident-sounding one isn't either.
2
Every question comes from your packet
No outside trivia, no surprise topics. If a student studied what you assigned, they have everything they need.
3
No "always C" patterns
We shuffle which letter is correct. The right answer earns its place by content — never by being in a predictable spot.
4
If GPT-5.5 still cracks it, we tell you
No silent passes. Anything we couldn't fully stump after 8 rewrites gets marked on your answer key with a note — your call whether to keep it.
