What is Perplexity AI?
Perplexity AI is an AI-powered search engine that searches the web in real time and synthesises answers with cited sources. Unlike ChatGPT (which has a knowledge cutoff), Perplexity always pulls fresh information. Unlike Google, it gives you a direct answer instead of a list of links to click through.
For marketers, Perplexity is invaluable for quick research, competitor analysis, finding statistics for blog posts and staying up to date with industry news. For accountants, it's useful for quickly understanding tax law changes, accounting standards and regulatory updates with source citations.
