Reviews
Love this AI from Perplexity. Heard about them on the Lex Fridman podcast. Nvidia invested in them so I knew their tech was next level. They are basically an aggregator with access to the leading AI language models and the user can pick and switch responses by switching the AI of choice. Most uniquely, they provide real sources which in the current state of AI language models is critical as the machines tend to hallucinate and often times you waste time going down rabbit holes. Highly recommend!
