The substantial Khan Academy Kids (the early-childhood K-2 app, free), Khan Academy India (the substantial Hindi-and-Indian-curriculum localisation initiative supported by Tata Trusts since 2018), plus the substantial broader Khan Academy international-localisation programme.\n\nFor a globally-mobile professional, Khan Academy provides foundational free K-12-and-undergraduate-fundamentals education with substantial Indian-learner engagement particularly among Indian K-12 students plus the substantial Indian undergraduate STEM-fundamentals reinforcement audience. The platform is substantially supported by major philanthropic donations including Bill and Melinda Gates Foundation, Reed Hastings of Netflix, plus the broader Khan Academy donor network.
