Build Deep CS
Knowledge
That Lasts.
DistroLearn uses the SuperMemo SM-2 algorithm to build genuine mastery of data structures, distributed systems, and system design — knowledge that helps you ace interviews and write better software every day.
In the AI coding era, the engineer who understands the foundations directs the agent — choosing the right architecture, catching bad patterns early, and shipping with confidence.
Built for engineers who think in systems
Interview Prep
Walk into FAANG and top-tier interviews with genuine depth — not surface-level familiarity. Know the trade-offs, not just the definitions.
Day-to-Day Engineering
Apply distributed systems patterns, choose the right data structures, and design scalable architectures in your actual work — not just on a whiteboard.
AI-Era Foundations
When you use AI code gen, the engineer who understands the foundations directs the agent well — minimizing bad patterns, reducing iterations, and cutting token cost.

Designed for how
engineers actually learn.
Flash cards, visual quizzes, and architecture puzzles — all scheduled by the SM-2 algorithm at the exact moment you need a review.
dashboard.daily_driver
Your daily learning command center
Every session starts with a clear mission: review due cards, complete a puzzle, watch a visualization. Daily streaks and XP keep momentum going — whether you're prepping for an interview next week or just staying sharp.
recall.question_mode
Real questions. Real depth.
Not trivia — conceptual questions that mirror what senior engineers discuss in system design interviews and architecture reviews. Understand replication, consensus, storage engines, and more at the level that actually matters.
"What is replication in distributed databases,
and why is it used?"

Not guesswork.
SuperMemo SM-2 Algorithm
Calculates the optimal moment to review each concept — right before your brain would forget it. The result is deep, durable knowledge that holds up under interview pressure and in production decisions.
Active Recall
Passive reading doesn't build the kind of knowledge you can apply under pressure. DistroLearn forces retrieval — the most effective learning technique in cognitive science.
CS Topics Coverage
Guide Your AI Agent
AI code gen is only as good as the engineer directing it. Deep CS foundations let you catch architectural mistakes early, choose the right patterns, and minimize costly iterations.
not a single shard."
Adapts to Your Level
Start as Novice, Intermediate, or Advanced. The SM-2 easiness factor adjusts after every session — weak areas get more attention, strong areas stay fresh.

How it works
Learn
Explore CS concepts through concise, depth-first explanations. Each concept is framed around both interview relevance and real-world application.
Practice
DistroLearn quizzes you with active recall prompts — flash cards, puzzles, and visual quizzes. Rate your confidence; the SM-2 algorithm adapts your next review.
Master
Concepts move into long-term memory. You build the kind of deep knowledge that holds up in interviews, architecture reviews, and AI-assisted development.
