Incepted in 2017 by Tanushree Nagori and Aditya Shankar, Doubtnut offers free solutions to users who can send snapshots of their doubts over the platform. The target audience here is the K12 segment, mainly answers for Mathematics doubts for IIT JEE examinations. Initially, they provided solutions for Math problems exclusively until August 2019, but since then they have ventured into other subjects like Physics, Chemistry, Maths and Biology.

Solutions given on the app are mostly in the form of screencast videos, with step-by-step audio instructions on how to reach the final answer.

Tanushree Nagori, Co-Founder, Doubnut, said,We aim to use technology to provide a democratic, comprehensive and easily accessible education solution to all students – in the language and manner that they best understand.

In less time, the startup asserted to have recorded over five million monthly active users (MAU) on its forum. About 12-13 million doubts are put forward every month, including a peak of 400,000 each day, and more than 4,000 videos are produced daily. The average video length is 4.5 minutes. Additionally, it has about two million subscribers on YouTube and is already getting more than 20,000 queries via WhatsApp, where it launched in June.

How The Platform Works

Doubtnut uses complex Artificial Intelligence (AI), Machine Learning (ML) algorithms, and image recognition technology to show video lessons in response to photos of text problems. Students have to snap a picture of the question and upload it on the app. The platform then scrapes the text using Optical Character Recognition (OCR), matches it with pre-recorded content in its database, and directs the user to a solution video. The average time spent by users on the platform is 17-20 minutes and can even go up to 40 minutes for highly engaged ones.


Omidyar Network and WaterBridge have invested about ₹35,000,000 ($539,000) on Doubtnut. In January 2020, the company raised $15 million in Series A round of funding from China’s Tencent Holdings, and existing investors Sequoia Capital and Omidyar Network India.
