Taz: your personal STEM simulations engine
Taz is a personal STEM simulations engine. Ask a question, open an interactive 3D lab, change a setting, predict what will happen and compare the result with your idea. Labs cover physics, chemistry, biology, Earth and space, and maths, alongside AI explanations, coding and hands-on activities. An adult creates each account and sets its limits.
Public lab overviews, short previews and guides can be read worldwide. The account platform is available in India and the United States. Interactive labs require sign-in. See current plans and pricing.

AI explanations can be wrong and simulations simplify the real world. Automatic checks run before and after AI answers, common personal details are checked, and parents set controls. Taz suggests a break after 60 minutes. Read the safety approach and its limits and common questions.
