## Brilliant

Brilliant takes a different approach to learning: rather than watching long videos or reading dense textbooks, you build understanding by solving interactive problems. Lessons break big ideas down into small visual steps, so concepts in algebra, calculus, statistics, logic and Python become intuitive. The platform is designed for self-paced learners from roughly middle-school level up to college and beyond, and it adds a new AI tutor called Koji who asks guiding questions and sketches on screen to help you find answers yourself.

Beyond pure math, Brilliant covers computer science fundamentals, programming, data analysis and how modern AI actually works, including neural networks, tokenization and model reasoning. Each track uses mastery assessments that adapt to your level, revisiting weak spots and serving targeted practice so progress is measurable rather than vague. Real-world examples, such as image filters or password security, connect abstract ideas to everyday technology.

The platform is also used by schools and families. It is accredited by ACS WASC, certified under the kidSAFE/COPPA program, and offers classroom and teacher programs so educators can assign adaptive lessons and homework. For individual learners, the app is available on web and mobile, with progress syncing across devices.

**Pricing & Plans:** Brilliant uses a freemium model: a limited free experience is available, while a Premium subscription unlocks the full course library and unlimited practice. Annual plans are the cheapest per month, and there are separate school/classroom plans.

- **Interactive problem-based lessons:** Learn math, science, CS and AI through short, visual exercises that build intuition step by step rather than passive video watching.
- **Koji AI tutor:** A visual, interactive tutor that works on a shared canvas, asks guiding questions and gives hints without simply revealing the answer.
- **Adaptive mastery assessments:** Quizzes and reviews adapt to your level, tracking what you have mastered and resurfacing topics that still need work.
- **Coding and CS foundations:** Write and run real code to learn programming logic, algorithms, data structures and debugging skills relevant to the AI era.
- **Courses for schools and families:** Accredited classroom programs let teachers assign adaptive lessons, with kidSAFE/COPPA-certified privacy protections.

**Strengths:** Hands-on, visual format makes abstract concepts easier to grasp; Access to the Koji AI tutor that guides rather than gives away answers; Accredited and kidSAFE/COPPA certified, suitable for schools and families; Works across web and mobile with syncing progress

**Limitations:** Full course library requires a paid Premium subscription; Not a replacement for formal instruction or credentials; Some advanced or niche topics are not covered deeply

## Prepform

Prepform frames itself as a complete learning system rather than a pile of practice questions. At its center is "Blend AI," an engine that personalizes the entire study cycle. It begins by helping you diagnose your current level, then builds a path that guides you through analysis, review, and evaluation of how you actually learn. The goal is to answer three questions for the student: what to study, how long to study it, and when a subject has actually been mastered.

The platform is openly student-driven and evidence-based. It pairs machine learning with established learning science such as spaced repetition, then layers data visualization and score prediction on top so you can see your weaknesses instead of guessing at them. Active learning is encouraged through interactive tools, immediate answer explanations, and a structured mistake log where you record what went wrong and what you should have noticed.

The workflow is deliberately cyclical: Practice, Analyze, Review, Retry. You work through exam-style questions, analyze your results and predicted scores, log your errors, and then revisit those mistakes at optimal intervals. By unifying lessons, questions, and explanations in one place, Prepform aims to help learners understand the concepts and relationships behind each question rather than simply memorizing answers.

**Pricing & Plans:** Prepform is offered as a freemium product with a free entry point, so students can begin studying without paying up front. Because the public site emphasizes the learning engine rather than published tiers, check inside the app for the current free limits and any paid upgrade options before committing.

- **Blend AI learning path:** The Blend AI engine recommends exactly what to study, how long to spend on it, and when you have genuinely mastered a topic based on your own performance data.
- **Adaptive spaced repetition:** Machine learning and spaced repetition decide which questions and mistakes to bring back, and at what interval, so review lands when it is most useful.
- **Data visualization and score prediction:** Charts, score prediction, and performance breakdowns expose the topics and question types where you are losing points.
- **Exam-style question bank:** Work through thousands of questions modeled on real exams, with immediate feedback and explanations that reinforce core concepts.
- **Mistake log and review loop:** Keep a running log of every mistake, note what you should have noticed, and retry those items later to convert errors into lasting understanding.

**Strengths:** Turns raw practice data into specific, actionable study recommendations; Bundles spaced repetition, machine learning, and analytics in one workflow; Mistake log and immediate explanations encourage genuine understanding, not answer memorization; Performance visualization makes weak topics and question types easy to spot

**Limitations:** The interface is a JavaScript app, so the marketing site alone gives little value before you create an account; No publicly advertised per-question bank sizes or a detailed pricing page at first glance; Best suited to self-directed students who will actually act on the analytics it surfaces; No live tutor or human element — everything is algorithm-driven
