AI Commentary
Perplexity has carved a distinct niche as the AI tool for research and fact-finding, competing more with Google Search than with ChatGPT. Its citation-first approach provides source transparency that general-purpose chatbots lack. The Pro tier's model choice—toggling between GPT-4o, Claude, and Perplexity's own Sonar—offers unusual flexibility. For generative tasks like writing or coding, purpose-built tools outperform it significantly.
