What is Perplexity?
Perplexity is a writing & productivity AI tool built for researchers, seo teams, analysts, and knowledge workers. An answer engine that combines AI responses with web citations for fast research and source discovery. Teams commonly evaluate it for source research, competitor checks, topic discovery, and related workflows where speed, repeatability, and quality control matter. Before adopting it, compare pricing, browser access, API availability, privacy terms, export options, and how much human review is required for your use case.
