Perplexity AI has created the most compelling AI-powered search experience available, combining large language model capabilities with real-time web search to deliver sourced, comprehensive answers to complex queries. The free tier is remarkably capable, while Pro at $20/month adds access to more powerful models and advanced features. What sets Perplexity apart is the citation model -- every claim is linked to its source, enabling verification that traditional AI assistants lack. This makes it genuinely useful for research, fact-checking, and staying current on rapidly evolving topics. The interface is clean and focused, avoiding the feature bloat of larger platforms. However, answer quality depends heavily on the quality of retrieved sources, and the platform can sometimes overweight SEO-optimized content. For anyone whose primary AI use case is knowledge retrieval and research, Perplexity is arguably the best tool available, offering a better experience than traditional search engines for complex queries.
