Reddit has filed a lawsuit against Perplexity and three other firms for allegedly scraping its content from Google search results without permission. The lawsuit claims these companies circumvented Reddit's data protection measures to obtain valuable data for AI training and resold it to other entities, including OpenAI and Meta.

Amazon has escalated its dispute with Perplexity by suing the startup for allegedly using its Comet AI browser to make unauthorized purchases on Amazon. The lawsuit claims this violates Amazon's terms of service and disrupts its business model by degrading the shopping experience. Perplexity argues that Amazon's legal actions stifle innovation and limit consumer choice.
