Brainly

Documented cause

Brainly built a peer-to-peer homework help platform with 350M+ users globally, raising $80M and reaching a $1B valuation. Its model: students ask questions, other students answer, with a premium subscription for faster expert answers. ChatGPT launched in November 2022 and immediately provided better, faster, free answers to every homework question Brainly's entire business model depended on. Subscription cancellations accelerated and the company laid off 20%+ of staff in 2023 as the product's core value proposition was commoditised by AI.

Alternative account: Brainly was a global peer-to-peer homework help platform, where students posted questions and other students (and tutors) answered them. With over 350 million monthly users at peak, Brainly was one of the most visited educational sites in the world — a truly global product with strong user bases across the US, Poland, Brazil, Russia, and India. The company monetized through a freemium subscription model (Brainly Plus/Tutor) that unlocked additional answer access and expert tutor responses. ChatGPT's launch in November 2022 was an existential event for the homework help category. Any question a student could post on Brainly could now be answered instantly, for free, by an AI that never got tired, was always available, and provided far more detailed explanations than peer answers. Brainly's peer-answer model — which required waiting for other students to respond — became fundamentally inferior overnight. Subscription revenue collapsed as users switched to AI tools. The company underwent massive layoffs in early 2023 and effectively shut down its North American operations, scaling back dramatically from its peak global footprint.
