Reddit has filed a lawsuit against AI company Perplexity for allegedly scraping its data on an “industrial scale” without proper authorization. The lawsuit, filed in California federal court, accuses Perplexity of using Reddit’s content to train its AI models and power its search engine without permission or compensation. Reddit claims this unauthorized data collection violates its terms of service and user agreement. The social media platform argues that Perplexity’s actions amount to theft of intellectual property and could potentially harm Reddit’s business model. The lawsuit highlights the growing tension between content platforms and AI companies over data usage rights. Reddit recently struck a $60 million deal with Google for AI training data, making this case particularly significant as it demonstrates Reddit’s stance on protecting its valuable data assets. The platform seeks monetary damages and an injunction to stop Perplexity from continuing to scrape its content. This legal action represents a broader industry trend where content creators and platforms are pushing back against AI companies’ unrestricted use of their data. The case could set important precedents for how AI companies can access and use online content for training purposes, potentially reshaping the relationship between content platforms and AI developers. Reddit’s action suggests a growing movement toward establishing clear boundaries and compensation frameworks for AI training data.
