Perplexity

Perplexity is an AI-powered search engine from the company of the same name, found at perplexity.ai. Instead of returning a page of links for you to sort through, it answers your question directly and shows the sources it drew from. You type a question in plain language, and the engine searches the web, reads what it finds, and composes a written answer with citations attached.

The core promise is verifiability. Because every answer points back to the web pages behind it, you can click through and check the original material rather than taking the summary on faith. That makes it a practical tool for research and fact-checking, where knowing where a claim came from matters as much as the claim itself. It fits the Productivity and Business Intelligence categories: it is a lookup and research tool you can reach for during everyday work, not a document editor or a dashboard builder.

One detail worth noting from the site itself: Perplexity's cookie policy states that the company uses cookies, pixels, SDKs, and similar technologies to measure ad performance on third-party partner websites and to improve its services, and that it does not use these technologies to sell third-party ads on its own services. That is the clearest statement on the homepage about how the company approaches advertising.

Best for

• Researchers and analysts who need answers with citations they can verify
• Writers and students gathering background material on a new topic
• Professionals checking facts before meetings, decisions, or deliverables
• Anyone who wants a direct answer instead of scanning a list of search results
• Teams using it as a quick business intelligence and market lookup tool

Frequently asked questions

What does Perplexity do?

It is an AI search engine. You ask a question in plain language, and it returns a written answer with citations to the web sources it used, rather than just a list of links.

How is it different from a traditional search engine?

A traditional search engine gives you links to read yourself. Perplexity reads the sources and gives you a synthesized answer, with the citations attached so you can check the originals.

Is Perplexity free?

The homepage we reviewed does not list pricing or plans. Check perplexity.ai directly for current pricing and any paid tiers.

Can I trust the answers it gives?

Every answer includes cited sources you can open and read. As with any AI-generated summary, it is worth clicking through on anything important rather than relying on the summary alone.

Does Perplexity show ads?

Its cookie policy says Perplexity does not use tracking technologies to sell third-party ads on its own services, though it does measure ad performance on third-party partner websites.

Who makes Perplexity?

It is built by Perplexity, the company behind perplexity.ai. The homepage does not provide further company details.
