Brainly

Brainly is an education technology company based in Kraków, Poland, with headquarters in New York City. It operates a user generated question and answer platform for students.

Initially called Zadane.pl, the company was founded in 2009 in Poland by Michał Borkowski (current chief executive officer), Tomasz Kraus, and Łukasz Haluch. The website is a peer-to-peer platform where students can ask questions, and answer them for other students. Ranks are provided to students who provide high-quality answers. The platform is moderated by both volunteers, staff, and machine learning algorithms. The first million unique monthly users were achieved within 6 months after the release.

In January 2011, the company founded Znanija.com, a Russian language version of the platform.

In June 2016, Brainly acquired the US-based OpenStudy.

In 2017, Zadane.pl changed to Brainly.

In January 2018, Brainly announced it had acquired the video education start-up Bask to add video features to its platform.

In 2020, the company experienced a significant increase in the number of users, caused by the global COVID-19 pandemic, from 150 million in 2019 to around 350 million in 2020.

In 2020, numerous users on the Art of Problem Solving website found that Brainly had compromised the integrity of the American Mathematics Competitions after posting the questions on its website with the correct answers. This led to Brainly updating its honor code.

As of 2020, the company had raised approximately $150 million in funding from investors.

In 2023, Brainly released artificial intelligence features for the platform.

In 2024, Brainly released Test Prep, an AI-powered tool to help students improve their test scores.

ToS;DR (Terms of Service; Didn't Read), a project which analyzes terms of services (ToS) and privacy policies of websites, ranks Brainly at grade D.
