Doubtnut, solving math problems through interactive videos
Doubtnut was founded by husband-wife duo Aditya Shankar and Tanushree Nagori in October 2017. They launched the platform aiming to make real-time doubt clearance an efficient feature, which many online learning platforms often lack. Doubtnut offers instant video solutions for doubts raised by students on an app-based platform. According to the co-founders, more than 90 percent of Doubtnut’s users are from non-metros - as the app is available in 11 regional languages. Since 2018, Doubtnut’s app has also consistently been featured in Google Play Store’s top 10 in the ‘education’ category. In April 2019, the company raised Rs 23 crore from Surge, an early-stage startup accelerator programme by Sequoia India. The funding round also saw participation from existing investors which include WaterBridge Ventures and Omidyar Network India, and new investor Akatsuki Entertainment Technology Fund Japan. According to Owler, Doubtnut has an estimated annual revenue of $2 million.

    A YourStory list of startups in 2019 with groundbreaking ideas that are creating a deep impact.
    According to a 2017 KPMG report, India's online education market is expected to grow to $1.96 billion and about 9.6 million users by 2021. In 2016, these numbers were $247 million and about 1.6 million users. The report also says that with an estimated 280 million students expected to be enrolled in schools by 2021, primary and secondary education will be the largest category at $773 million, and test preparation will be the fastest-growing category. It also adds that one of the key challenges faced by students in offline channels is doubt clearance, and one of the main barriers to adopting online channels is getting real-time solutions to queries. This is where Doubtnut plays a huge role. Today, we have a large number of online platforms where students can access lessons and teachers, but clearing doubts remains an issue. Doubtnut uses complex artificial intelligence (AI), machine learning (ML) algorithms, and image recognition technology to show video lessons in response to photos and texts of doubts uploaded by students. Doubtnut claims to have 80-90 percent platform accuracy. And, the remaining 10-20 percent can be achieved by asking a query to human tutors available on the app. At times, the startup also takes note of the doubts that could not be solved and creates videos explaining them within just a few hours. According to Co-founder Tanushree Nagori, the student demographic on Doubtnut is diverse, with children of ‘farm labourers and cement factory workers’ also accessing the app.
