According to FT, Reddit filed the lawsuit that day in a federal court in New York against Perplexity and three data scraping companies. Reddit claims that these three data scraping firms unlawfully scraped its data from billions of search results. Reddit also alleges that Perplexity was a client of at least one of these companies. Reddit asserts that Perplexity needed to collect data from Google search results in order to operate its “answer engine.”


In response, Perplexity stated, “We will always fight for users’ rights to access public knowledge freely and fairly,” adding, “While providing fact-based answers with accurate AI, our approach remains principled and responsible.”


Perplexity is an AI startup founded in 2022 by Aravind Srinivas, a former OpenAI employee, among others. From the outset, it has provided search services based on AI and is competing with Google and OpenAI. Citing sources, FT reported that Reddit raised allegations of data misappropriation against Perplexity and proposed discussions on a paid partnership, but founder Srinivas showed no interest in the offer.



Reddit, which went public in March 2024, has partnered with Google and OpenAI, allowing them to train large language models using its content. Reddit has also conveyed related concerns to Google, reportedly requesting an investigation into whether Perplexity is scraping its data through search engines. According to FT, this lawsuit is one of dozens of copyright disputes filed against AI companies since the emergence of generative AI.
