Nice — that 3-letter word repeats. In English, the most common trigraph is THE. What shift maps QEB → THE?

Invitational, Regional, and State Finals medals
from seasons I've coached
Built by a coach who figured out how to actually teach this. I coached my daughter's Codebusters team — three kids, zero cipher experience — to a state medal, by applying my background as an AI product manager to design the right tool and explanation for how each cipher is actually learned. Professor Lock is that same approach, built into an AI coach.

Worksheets don't tell you why you're stuck. A real coach does. Codebusters AI is that coach — available every night, at exactly your level.
- Old practice tests with no answer keys or explanations
- Getting stuck on Xenocrypts with nowhere to ask
- No way to measure speed against real competition pace
- Generic tutoring that doesn't know Codebusters rules
- Infinite fresh puzzles graded instantly with worked solutions
- Socratic hints that nudge you forward without spoiling the answer
- CPM + accuracy tracked per cipher, benchmarked to medalists
- Trained specifically on every official cipher in the rule manual

"You've got Caesar and Aristocrats down — to medal at States, focus on Aristocrat speed drills and start learning Patristocrats while your partners focus on xenocrypt and Math ciphers. Practice 20 min/day, 5 days a week. I'm certain to see you improve in our next Timed Practice Test."
Every tool a medal-winning team uses.
Unlimited practice puzzles
20+ cipher types — Caesar to Xenocrypts — generated fresh, never recycled.
Socratic AI hints
Stuck? The coach nudges you one logical step at a time — so you learn patterns, not answers.
Personalized practice plan
A daily path tuned to your diagnostic — for Regionals, States, or Nationals.
Timed mock tests
50-minute simulations that mirror real Div B and Div C packets.
Progress dashboard
Track CPM, accuracy, and mastery per cipher — see exactly what to fix next.
Custom cipher tools
Interactive tools that distill how each cipher works — so you understand the mechanics, not just the solution.
Feynman-method learning
Learn by explaining: our Feynman-method module walks you through each cipher until you can teach it yourself.
Built by a coach who's been there.
"I coached my own Science Olympiad team from Regionals to States — and along the way, I realized every Codebusters competitor needs the same thing: unlimited practice with instant, Socratic feedback. That's exactly what Professor Lock does."

Read the full storyIs this allowed by Science Olympiad?
Yes. Codebusters AI is a practice and training tool — the same category as a prep book, a flashcard app, or working with a private tutor. Students use it at home to build speed and intuition. They do not use it during the actual tournament.
Science Olympiad rules prohibit certain tools during competition (calculators, reference sheets, etc.), but they do not restrict how students prepare at home. As of the 2026 rules, no official Science Olympiad publication explicitly addresses AI-based practice tools — because the rules govern what happens at the tournament table, not what students do to get ready for it.
If a coach or tournament director has a specific concern, we're happy to provide a detailed breakdown of what the tool does and how it's used. Reach out anytime.
