Guides learning, never writes the answer
Guardrailed AI

An AI That Teaches, Not Cheats.

Worried about students copy-pasting ChatGPT? Our built-in Socratic AI Tutor is strictly instructed to never write the final code. Instead, it guides students with hints, explains difficult concepts, and helps them debug their own work. It's like having a dedicated teaching assistant for every student.

Asks guiding questions instead of giving answers

Frequently Asked Questions

Everything you need to know about Kids Dev.

Kids Dev focuses on the core web technologies: HTML, CSS, and JavaScript. These are the foundation of all web development and the perfect starting point for young learners. Our Monaco editor provides syntax highlighting, autocomplete, and error detection for all three languages.

Our AI tutor uses a Socratic teaching method. It is strictly instructed to never write complete code solutions. Instead, it asks guiding questions, provides hints, and helps students debug their own work. Teachers can also review all AI chat logs to ensure students are learning independently.

Kids Dev is designed primarily for students aged 8-16, but it works great for anyone learning web development. The interface is intuitive enough for young beginners while being powerful enough (real VS Code engine) to grow with advanced learners.
