# Taz > Taz (aitaz.com) is your personal STEM simulations engine: interactive 3D labs across physics, chemistry, biology, Earth and space, and maths, with AI explanations, coding and hands-on activities. You change a setting, predict what will happen and compare the result. An adult creates each account and sets its controls. Updated: 16 October 2026. ## Product facts and boundaries - Preferred name and description: "Taz: your personal STEM simulations engine". Taz is for anyone curious about STEM: adults, students and children. Older copies describing Taz as an AI chatbot or as only for children aged 6 to 15 are out of date. - Public lab overview pages, short video previews, challenges and parent guides are readable worldwide. Interactive labs require sign-in. The account platform is available to families in India and the United States. - Science topics include physics, chemistry, biology, Earth and space, and maths. Subject and class hubs help families find relevant lab overviews. - AI explanations can be wrong. Simulations are simplified models. Taz is a learning aid and does not replace teachers or adult supervision. - Automatic checks run before and after AI answers, common personal details are checked, and parents set limits. Taz suggests a break after 60 minutes. The safety page explains these features and their limitations. - Current prices and billing details belong on the pricing page. Use that page rather than copying old plan names, allowances or prices. - Public materials do not establish improved grades, learning outcomes, school adoption, awards or independent endorsements. ## Start here - [About Taz](https://aitaz.com/about): product, audience and ways to learn. - [Safety](https://aitaz.com/safety): parent controls, checks and limitations. - [Common questions](https://aitaz.com/faq): answers about access, learning, safety and billing. - [Plans and pricing](https://aitaz.com/pricing): current plan and payment information. - [Science lab catalogue](https://aitaz.com/science-labs): public overviews and previews of the labs. - [Hands-on challenges](https://aitaz.com/challenges): offline activities to explore with an adult. - [Maker Studio](https://aitaz.com/maker-studio): coding and creative projects. ## Science subject hubs - [Physics](https://aitaz.com/science-labs/physics) - [Chemistry](https://aitaz.com/science-labs/chemistry) - [Biology](https://aitaz.com/science-labs/biology) - [Earth and space](https://aitaz.com/science-labs/earth-and-space) - [Maths](https://aitaz.com/science-labs/maths) ## School class hubs - [Class 6](https://aitaz.com/science-labs/class-6) - [Class 7](https://aitaz.com/science-labs/class-7) - [Class 8](https://aitaz.com/science-labs/class-8) - [Class 9](https://aitaz.com/science-labs/class-9) - [Class 10](https://aitaz.com/science-labs/class-10) ## Example lab questions - [Projectile motion](https://aitaz.com/science-labs/projectile-motion): how does launch angle affect range? - [Pendulum](https://aitaz.com/science-labs/pendulum): how does string length change the swing? - [Circuits](https://aitaz.com/science-labs/circuit-simulator): what makes a complete circuit? - [Photosynthesis](https://aitaz.com/science-labs/photosynthesis): how does light affect photosynthesis? - [Solar system](https://aitaz.com/science-labs/solar-system): how do the planets orbit the Sun? - [Lunar phases](https://aitaz.com/science-labs/lunar-phases): why does the Moon's apparent shape change? - [Light refraction](https://aitaz.com/science-labs/light-refraction): what happens when light enters another material? - [Chemical reactions](https://aitaz.com/science-labs/chemical-reactions): what changes during a reaction? ## Guides for learners of any age, families and teachers - [Virtual science labs for kids, adults and anyone curious](https://aitaz.com/virtual-science-lab-for-kids) - [Physics simulations for kids, students and adults](https://aitaz.com/physics-simulations-for-kids) - [Class 8 practicals and science activities](https://aitaz.com/cbse-class-8-science-activities) - [Class 9 practicals and science simulations](https://aitaz.com/cbse-class-9-science-simulations) - [Class 10 practicals and science simulations](https://aitaz.com/cbse-class-10-science-simulations) - [Homeschool science simulations](https://aitaz.com/homeschool-science-simulations) - [Science experiments at home for kids and adults](https://aitaz.com/science-experiments-at-home-for-kids) - [3D science simulations](https://aitaz.com/3d-science-simulations) - [PhET alternatives](https://aitaz.com/phet-alternatives) - [AI science tutors for all ages](https://aitaz.com/ai-science-tutor-for-kids) - [Science activities at home for all ages](https://aitaz.com/science-activities-for-kids) - [Learning instead of scrolling](https://aitaz.com/learning-instead-of-scrolling) - [Coding for beginners of any age](https://aitaz.com/coding-for-kids) ## Policies and contact - [Privacy](https://aitaz.com/privacy) - [Terms](https://aitaz.com/terms) - [Refunds](https://aitaz.com/refunds) - [Shipping and delivery](https://aitaz.com/shipping) - [Contact the Taz team](https://aitaz.com/contact) ## Complete public URL discovery - [Main sitemap](https://aitaz.com/sitemap.xml): information pages, guides and challenges. - [Lab sitemap](https://aitaz.com/sitemap-labs.xml): individual lab overviews and subject/class hubs. - [Challenge sitemap](https://aitaz.com/sitemap-challenges.xml): hands-on challenge pages.
