In the midst of the drama surrounding Anthropic, OpenAI, and the US Department of Defense, another AI startup, Perplexity AI, has come under fresh scrutiny after being accused in a class-action lawsuit. The popular AI-powered search and answer engine platform has been accused of embedding hidden trackers that secretly route sensitive user conversations and personal data to Meta and Google without proper consent.
