Perplexity
Perplexity Is Replacing Google for Millions of Research Queries
Why We Picked It
Perplexity has emerged as the leading AI-powered search engine, combining real-time web access with AI synthesis to deliver comprehensive, cited answers. For research, fact-checking, and complex queries, it's become indispensable.
Full Review
Perplexity sits at the intersection of search engine and AI assistant, and it excels at both. Unlike ChatGPT, every answer comes with cited sources, making it ideal for research and fact-checking. The Pro Search mode performs multi-step research, asking clarifying questions and exploring multiple angles before delivering a comprehensive answer. Collections let you organize research into projects. The Discover feed surfaces trending topics with AI analysis. The free tier is surprisingly generous for basic queries. The Pro plan ($20/month) unlocks unlimited Pro Searches, file uploads, and access to GPT-4 and Claude models. Where Perplexity falls short is in creative tasks (writing fiction, brainstorming), sustained conversations, and tasks that don't benefit from web access. It's a research powerhouse, not a general-purpose assistant.
