Perplexity
AI search engine that answers questions with cited sources and real-time web access.
What it does
Perplexity is an AI-powered search engine that provides direct answers to questions with cited sources rather than a list of links. It combines the breadth of web search with the reasoning ability of large language models to synthesize information in real time. Perplexity Pro adds deeper research modes, file uploads, and the ability to choose between underlying models including Claude and GPT-4.
Why AI-NATIVE
The product is built entirely around AI-powered search and synthesis; there is no pre-AI Perplexity that the AI was added to.
Best for
Small teams use Perplexity for rapid competitive research, market monitoring, and fact-checking without a dedicated research function.
Mid-market teams with research-heavy workflows use Perplexity's API to embed real-time search and synthesis into internal tools.
Small businesses use Perplexity Pro for deeper research on market trends, regulatory changes, and competitor activity with cited sources.
Researchers, writers, and knowledge workers replace traditional search with Perplexity for faster, cited answers without having to triangulate across multiple tabs.
Limitations
Perplexity searches the open web only — it cannot answer questions about internal documents, CRM data, or anything not publicly available online.
Citations make answers feel authoritative, but Perplexity can still misread or misrepresent source content — important claims should be verified at the original source.
For deeply niche or technical subjects, Perplexity synthesis can miss important nuance that a domain expert or dedicated research tool would catch.
