What is Perplexity AI?
Perplexity AI is an AI-powered search engine that combines the conversational ability of large language models with real-time web search. Unlike ChatGPT or Claude — which can have outdated training data — Perplexity searches the internet for every query and presents answers with numbered citations you can click to verify.
Think of it as Google Search, but instead of giving you a list of links to sift through, it reads them for you and synthesizes a direct, accurate answer. This makes it the best AI tool for research, journalism, academic work and any situation where accuracy and source attribution matter.
The free plan is genuinely powerful — you get unlimited searches with standard AI. The Pro plan ($20/month) adds access to GPT-4o and Claude for answers, image generation and file uploads.
