AdaQuiz

AdaQuiz is an adaptive learning platform for programming languages that delivers interactive quizzes to help users improve their coding skills. It targets developers and learners seeking to master JavaScript, Python, Java, C++, Go, Rust, and similar languages through repeated practice and performance tracking.

The service employs an SM-2 spaced repetition algorithm to adjust question timing according to individual performance. It generates fresh questions with OpenAI to avoid repetition and supplies material across multiple difficulty levels. Users receive detailed analytics covering strengths, weaknesses, performance trends, and improvement over time. Additional capabilities include auto-save to resume incomplete quizzes, keyboard shortcuts for navigation, smart question selection that mixes reviews with new content, and a reporting tool for unclear or incorrect items.

AdaQuiz runs as a responsive web application compatible with phones, tablets, and desktops. The platform is currently in beta and evolves according to user feedback.

It follows a tiered monthly subscription model that can be canceled at any time. The free plan permits one quiz per day with up to 25 questions at easy and medium difficulty. The Plus plan costs 5.99 per month and raises the limit to five quizzes per day with access to hard questions and basic statistics. The Pro plan costs 9.99 per month and provides fifteen quizzes per day, up to 40 questions per quiz, advanced insights, performance trends, and weakness detection.
