Perplexity is an AI-powered search engine. You ask a question, it searches the web, reads the top sources, and gives you a summarized answer with citations. It’s not a general-purpose AI assistant — it’s specifically built for research and information-finding tasks.

What it is

Perplexity combines a search index with a large language model. When you submit a query, it retrieves current web sources and synthesizes them into a direct answer, showing you exactly which sources each part of the answer came from. It updates in real time — unlike standard LLMs, Perplexity has access to current information. The Pro tier adds deeper research modes (including “Deep Research,” which runs a multi-step research process), access to different underlying models (GPT-4o, Claude, Sonar), and image generation.

What it’s best at

• Quick factual lookups that need to be current (pricing, availability, recent news)
• Competitor research — find and summarize what competitors offer without clicking 10 tabs
• Market research starting points — who are the players, what are the common complaints
• Cited summaries of topics you need to understand quickly
• Following up on news stories with context
• Building a research base before writing a proposal or sales document

How operators use it

Operators use Perplexity as a replacement for opening multiple search tabs. Instead of Googling a topic and piecing together five articles, you ask Perplexity once and get a synthesis with sources to verify. It works well for supplier research (“what are the main complaints about [vendor] on Reddit and review sites”), local market data (“what are typical commercial lease rates in [city]”), and preparing for a customer call (“what does [company] do and who are their competitors”). The citations are important — treat them as a starting point to verify, not as a final source.

Getting started & pricing

• Free: Unlimited basic searches, limited Pro searches per day
• Pro ($20/month): Unlimited Pro searches, Deep Research mode, file uploads, image generation, model switching
• Enterprise: Team controls, SSO, private data connectors — contact sales

Go to perplexity.ai and start searching. No configuration needed. For most operators, the free tier is enough to test the value; upgrade to Pro if you run frequent research tasks or want the Deep Research mode for longer investigations.

Bottom line

Perplexity fills a gap that general AI assistants don’t: real-time, cited web research. It won’t replace ChatGPT or Claude for drafting and reasoning, but for anything where you need current information with traceable sources, it’s faster and more reliable than standard search. For operators doing regular competitive or market research, the Pro subscription pays for itself quickly.
