Doubtnut is an Indian interactive online tutoring app which was started by Tanushree Nagori and husband Aditya Shankar, in 2016.[3] In 2009, the couple had started giving offline tutoring to grade 9 to 12 students, where they taught mathematics and science. Doubtnut is available as an Android application or by accessing its official website


The platform uses image recognition technologies to provide solutions of some mathematical and science questions.[1][4] To find the solution to a question, one has to upload an image depicting the question. The app extracts text from the image and tries to match it in its database of questions which are pre-answered, having recorded video solutions. If it finds a match, then the result is provided to the user otherwise it asks the user to post their question publicly for tutors available on the platform to provide a video explaining their query.[citation needed]


Doubtnut received its first funding of US$100K from Ankit Nagori of in April, 2017.[citation needed]

In 2019, Omidyar Network and WaterBridge invested about $470,000.[5] In January 2020, the company raised $15 million in Series A round of funding from Tencent Holdings, and existing investors Sequoia Capital and Omidyar Network India.[6][7]
