What is Perplexity AI?
Perplexity has carved out a unique niche: it's not just a chatbot, it's an AI-powered search engine. Every answer comes with numbered citations pointing to real web sources, which makes it much easier to verify information than with ChatGPT or Claude. The Pro plan ($20/month) unlocks access to GPT-4o, Claude 3, and Gemini models, plus unlimited file uploads and a higher daily query limit. For researchers, journalists, and students who need accurate, sourced information quickly, Perplexity is genuinely one of the most useful AI tools available. The 'Spaces' feature lets you create custom research assistants.
