Existing learning tools aren't working.
Most learning apps are built on streaks and gimmicks — or on memorization-heavy approaches from the 1800s. Nothing ever comes back to ask whether last week's work survived, so it quietly doesn't. Learners grind, forget, and give up before the skill they wanted ever shows up.
Passive review
Reading notes doesn't build retention
No adaptive pacing
One-size-fits-all curricula frustrate learners
No mastery gates
Students advance before they're ready
Learning science, finally applied for real.
MasteryHelp combines the best of modern education research with AI tutors that know each course cold — currently Koine Greek, Biblical Hebrew, and Japanese.
Spaced Repetition
SM-2 algorithm schedules each card at the optimal moment for long-term retention — just like Anki, but built into the course.
Mastery-Based Progression
You don't advance until you've proven you know the material. Each unit has a mastery threshold — no shortcuts.
Adaptive Pacing
The system watches your performance and adjusts. Struggling? Slow down. Flying through? Accelerate.
AI Tutor
Ask anything about grammar, vocabulary, or translation. The AI tutor understands your current lesson and gives contextual explanations.
Our Approach
"If you got 70% on an exam, you didn't know 30% of the material. And that 30% isn't random — it's probably the hardest 30%, the part that everything else builds on."
— Sal Khan, The One World Schoolhouse
We built MasteryHelp on sixty years of adult education research. No guessing what "good enough" means. No moving forward until the foundation is solid. Read why.
