About
AlgoBook is an AI-powered coding practice platform built to help developers sharpen their problem-solving skills and prepare for technical interviews — smarter, not harder.
We believe coding-interview preparation should be personalised, intelligent and accessible. Traditional platforms give you a static list of problems. AlgoBook goes further — it understands your strengths and weaknesses, adapts to your level and generates fresh, verified challenges. Our goal is to make every developer interview-ready through smart, adaptive practice.
Every generated problem ships with a reference solution that is executed against every hidden test before it is saved. A broken driver never reaches your editor.
AlgoBook AI generates LeetCode-style problems around your goal, your weak topics and your rating band — and reuses verified problems from the shared pool when one fits.
Topic mastery, spaced repetition, a practice-state machine and an Elo-style rating decide what you solve next. Struggling with graphs? You get graphs. Mastered arrays? Time to move on.
Streaks with freezes, XP and levels, achievements, a daily challenge and leaderboards make daily practice a habit. Your profile tracks every step.
AlgoBook is a product of CognitiveSquad, a team passionate about combining artificial intelligence with education technology. We build tools that make learning more effective and accessible for developers around the world.
