An AI tutor that draws every step of the answer on a whiteboard
Every answer is drawn out live on the board — graphs, diagrams, arrows and step-by-step working — while the tutor narrates what it is doing.
Rather than dumping the answer, the tutor guides you one hint at a time and checks your reasoning so you can solve the next problem alone.
Upload a study guide, PDF or slides and it becomes a structured run-through of key points, common traps and a short quiz.
The tutor speaks and writes on the board in English, Chinese, Spanish, French, German, Italian, Portuguese, Japanese, Korean and Malay, switchable mid-lesson.
Learn to code free with hands-on lessons and instant playgrounds
Short, practice-first coding lessons that run directly in your browser, so you can start learning without installing a compiler or development environment.
Dedicated playgrounds for Python, JavaScript, C, C++, Java, SQL, React, Go, Swift and many other languages let you test snippets and experiment immediately after each lesson.
Structured curricula such as Software Engineer, Frontend, Full Stack, Backend, Data Analyst, Data Scientist, DevOps and game development bundle the skills employers actually ask for.
Streak-style daily coding challenges and progress tracking help learners build a consistent habit and stay motivated between longer courses.
