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.

Multi-modal human interaction datasets for AI model training
Datasets covering image, video, audio, code, text, and conversational interaction for varied model-training needs.
Buyer-scoped datasets with configurable anonymization, filtering, modalities, and delivery formats.
Conversational and text data spanning 100+ languages, including low-resource and underrepresented regions.
Signals that are aligned, annotated, and validated for cross-modality and scientific consistency.
