Zettel.study is an AI-powered learning platform that teaches coding through hands-on projects in a real development environment. It builds personalized curricula from a short interview about the learner's goals and knowledge, then provides an AI tutor that watches their work in real time and offers proactive help. Unlike passive video courses or AI code generators, Zettel focuses on developing independent problem-solving skills by having users write real code from the first lesson.

Problem
Traditional coding courses and AI tools often fail to develop independent problem-solving skills. Learners either follow step-by-step exercises that create a false sense of progress or rely on AI that writes code for them, leaving them unable to build anything on their own. This gap between learning syntax and actually thinking like a developer is a major barrier for aspiring programmers.
Solution
Zettel.study provides an interactive learning platform that combines a personalized curriculum with an AI tutor that actively watches the learner's work. The platform begins with a short conversation about the user's knowledge, goals, and available time, then builds a custom curriculum with a clear sequence and starting point. Lessons are conducted inside a real IDE with a terminal and LSP, where users write actual code from the first lesson. The AI tutor monitors terminal output, file changes, and errors in real time, offering proactive help when the user is stuck and staying out of the way when they are on track. This approach ensures learners develop practical skills by building real projects, not just completing fill-in-the-blank exercises.
Target Audience
Primary users are self-directed learners who want to go beyond syntax and actually build software, as well as career switchers and junior developers seeking to develop independent problem-solving skills in a real development environment.
Features
- Personalized curriculum generated from a short interview about the user's knowledge, goals, and time availability
