Doubtnut is a multi-lingual online learning platform that uses AI technologies for image recognition, natural language processing and proprietary machine learning algorithms to throw up solutions to students’ queries.

Students simply snap a photo of a problem and the Doubtnut app serves up a video of a solution and suggests other concept videos to help students learn the topic better. The app, which can read questions in 16 Indian languages, as well as English, currently covers solutions to math problems from Grade 6 to 12. But this will expand to cover other subjects in the next few weeks.

Over 90% of Doubtnut users are in Tier 2 and Tier 3 cities, and much of the growth continues to come from outside India’s larger metropolitan centres. Doubtnut, which currently has Hindi videos, plans to offer video content in other regional languages. The app already offers features such as quizzes, assessments and communities to increase student engagement.

The company has 3.5m+ monthly active users and 8m+ monthly video views across platforms, and the app is ranked amongst the top 10 free education apps on Google Playstore in India

Doubtnut was founded by Tanushree Nagori and Aditya Shankar, IIT-Delhi alumni who are veterans in the education space. In 2009, the husband-and-wife team set up Class 21A, a brick-and mortar coaching centre, where they taught math and science to high school students.
