Perplexity

Perplexity is an AI-powered search engine that answers questions directly using real-time web information, with every claim sourced and cited. It combines the conversational interface of a chatbot with the accuracy and currency of live web search. It solves the two biggest problems with traditional AI assistants and traditional search simultaneously. Regular AI chatbots have knowledge cutoffs and can hallucinate facts. Regular search engines give you ten blue links but no synthesis. Perplexity gives you a direct, sourced answer and lets you follow up conversationally. Perplexity is used by researchers, analysts, students, journalists, and professionals who need accurate, up-to-date information quickly without sifting through search results manually. Core features: Real-time web search with automatic source citation for every factual claim in every answer. Follow-up questioning that maintains context across a full research thread. Perplexity Pro Search mode that performs deeper multi-step research using multiple sources before synthesizing an answer. Pricing: Free plan with standard search. Perplexity Pro at $20/month for unlimited Pro Search, file uploads, and access to advanced models including GPT-4o and Claude.
