India is the world's second-largest Android market with over 700 million Android users. AI has become the fastest-growing category on the Google Play Store, with the top AI apps collectively downloaded over 500 million times in India in 2025. But most Indian users are only using 1–2 AI apps — typically just the ChatGPT or Grok app — and missing a wider ecosystem that could save hours of daily work. This guide covers the best AI apps for Android across every major use case for Indian students and professionals.
