4 levels
Conceptual to expert, calibrated per learner
80% gate
Mastery threshold that unlocks each new lesson
FSRS
Reviews timed to the moment you start to forget
Everything you need to actually finish what you start
Most learning apps deliver the same content to everyone. Mastery builds the course around the person taking it.
Adaptive placement testing
A CAT-style test estimates your ability in real time, asking harder questions as you succeed. The result becomes a cognitive profile: strengths, gaps and the concepts worth revisiting.
AI-generated personal syllabus
Your topic becomes a prerequisite-gated lesson tree. Concepts are ordered so nothing depends on something you have not learned yet, with depth matched to your level.
Mastery exams that gate progress
Finish a lesson, take a generated exam, score 80% or more to unlock the next topic. Miss the bar and you get a remedial plan built from your actual wrong answers.
AI tutor grounded in the lesson
Ask questions inside any lesson. The tutor answers from that lesson's material, at the vocabulary level you chose, and streams its reply as it thinks.
Spaced repetition across tracks
Mastered concepts become flashcards scheduled by an FSRS-style algorithm. One daily review mixes cards from every subject you are learning.
Progress you can trust
Track completion, mastery scores, due reviews and streak-free progress are all visible per track and per lesson, with no guesswork about what to study next.
From curiosity to competence in four steps
No course catalogue to scroll. Describe what you want to learn and the platform builds the path.
Step 1
Create your account
Sign up with an email and password in seconds. No card, no trial countdown.
Step 2
Take the adaptive placement test
Pick a topic and answer questions that adapt to your answers. In about two minutes you get a level and a cognitive profile.
Step 3
Study and pass mastery exams
Work through your generated lessons, chat with the AI tutor and score 80%+ on each exam to unlock the next topic.
Step 4
Review and keep it
Every mastered concept becomes a flashcard. Daily reviews keep the whole syllabus retrievable months later.
One platform, four literacy levels
Your placement result sets the reading level, lesson depth, exam difficulty and even how the AI tutor talks to you.
Beginner · conceptual
Plain-language explanations, worked examples and vocabulary support. Ideal if the field is new or you have been away from it for years.
Intermediate · practical
Applied problem solving, guided exercises and trade-offs. You learn by building things, with theory introduced only where it pays off.
Advanced · theoretical
Deeper derivations, edge cases and exam-style rigour. Assumes solid fundamentals and rewards precise reasoning.
Expert · systemic
Nuanced trade-offs, literature-level detail and open-ended analysis. Designed for practitioners who need the whole system, not the basics.
Frequently asked questions
What is Mastery?
Mastery is an adaptive learning platform. You tell it what you want to learn, answer a short adaptive placement test, and it generates a personal prerequisite-gated syllabus matched to your level. You then study AI-written lessons, pass a mastery exam to unlock the next topic, and keep everything fresh with spaced repetition.
How is the study plan personalised?
Your placement test estimates your ability with a CAT-style adaptive algorithm, then combines it with your goals, prior experience and comfort level to pick one of four literacy levels: beginner conceptual, intermediate practical, advanced theoretical or expert systemic. The syllabus, lesson depth, exam difficulty and tutor tone all follow that profile.
How do mastery exams work?
Every lesson ends with a generated exam. You need 80% to unlock the next lesson. If you fall short, the platform writes a targeted remedial plan from your wrong answers and gives you fresh questions to retake, so gaps are closed before you move on.
What is spaced repetition and why does it matter?
Spaced repetition schedules each flashcard for review at the moment you are about to forget it, using an FSRS-style scheduler. Cards you find easy appear less often; cards you struggle with come back sooner. This is what keeps a finished syllabus from fading away.
Can I learn more than one subject?
Yes. Each subject is an independent learning track with its own placement test, syllabus, mastery exams and flashcard deck, while one dashboard shows overall progress and due reviews across everything you are studying.
How much does it cost?
Mastery is free to use. Create an account, take a placement test and start mastering any subject at no cost.
