Perplexity AI
AI-powered search engine that answers questions with real-time citations
Overview
Perplexity AI is an AI search engine that provides direct answers to questions with real-time web citations. It combines large language models with live web search to deliver sourced, accurate responses for research, academic work, and everyday questions across any topic.
Our take
Perplexity answers questions with live search and inline citations, which makes it more reliable for current information than an assistant answering from training data. The citations are the product's real value, and using it well means clicking them — a cited answer can still misrepresent what the source says.
Worth it if
Questions about current events, products and facts where you want sources you can check.
Look elsewhere if
Extended creative or reasoning work, where a general assistant is better suited.

❓ Frequently Asked Questions
Are the citations trustworthy?
The sources are real, which puts it well ahead of models that invent them. What still happens is misattribution — the cited page exists and does not quite say what the summary claims. Opening the sources is the habit that makes this tool safe, particularly for anything you will repeat or act on.
Does it replace a search engine?
For questions with a specific answer, often — you get a synthesis instead of ten links. For browsing, shopping, and cases where you want to judge sources yourself, conventional search is still better. Many people use both, which is a reasonable outcome rather than a failure of either.
