What is Perplexity AI?
Perplexity AI reimagines search as a conversation.

This makes it the most trustworthy AI assistant for research, fact-checking, and staying informed on current events. The free tier supports unlimited basic searches. Perplexity Pro ($20/mo) unlocks Pro Search with Claude, GPT-4, and other advanced models, plus file upload analysis and API access. Focus modes narrow searches to academic papers, YouTube videos, Reddit discussions, or writing assistance. Collections allow organizing research into shareable projects. Perplexity is particularly valuable for journalists verifying claims, researchers surveying literature, students writing papers, and professionals who need sourced answers rather than AI-generated opinions.
