Perplexity AI
Perplexity AI is the scrappy, source-citing answer engine eating Google and ChatGPT's lunch, but its big-boy ambitions just got a Comet-shaped turbo boost.
The context
Perplexity AI is trending because it just made its AI browser “Comet” free in March 2026, dropping a agentic research powerhouse into everyone’s pocket. The company has been on a rocket ship: hundreds of millions in funding from Jeff Bezos, Nvidia, and others, a valuation north of $1B, and a product that dares to challenge not just ChatGPT but Google itself. The buzz is a mix of genuine user love for its sourced, conversational answers and a persistent cloud of controversy over web scraping, alleged paywall bypass, and murky publisher relations. Everyone wants to know: who’s behind this thing, is it safe, and should they switch from their current AI darling?
