What is Perplexity?
Perplexity describes itself as an AI-powered answer engine. Instead of a list of links, you get a written answer to your question with references you can open and check, which makes it useful for quick research and for finding primary sources.
The service can be used for free. Perplexity Pro adds access to more AI models, extended deep research, more file uploads and what the company calls deeper sourcing.
Answers are only as reliable as the sources behind them. Open the cited pages for anything important, especially prices, legal rules and statistics.
