Perplexity is an AI answer and research service focused on the web. It is a useful starting point when you need a sourced overview of a question and want to follow the supporting pages. Treat the response as a research aid: the links matter as much as the summary, especially for dates, product details, and comparisons. This guide explains its purpose and a starting workflow. [1]
Main features
Perplexity describes its answer engine as providing cited answers and follow-up research. The service also has other products, including Computer, the Comet browser, and an API platform. This entry focuses on the answer-engine workflow. The Free Standard plan includes basic searches and limited access to advanced searches and file uploads; paid tiers provide different allowances and capabilities. [1]

Free access and pricing
Standard is free. Paid individual options include Pro and Max, with separate education and enterprise offers. The developer API is a separate product. Compare the current official plan details for advanced-search allowances, model access, and file handling before paying; these vary by tier. [2]
Limitations and practical advice
eWiki's practical advice: a citation can be relevant without proving the exact sentence beside it. Check publication dates and distinguish a vendor's claim from independent evidence. Avoid treating source count as a measure of accuracy. For a private set of documents, consider a source-focused notebook workflow instead.
