How to use Perplexity AI, and how is it different from a search engine?

How Perplexity works

Perplexity can be thought of as an answer tool with Internet search. You tell it what you want to find out with a complete question, and it will search the web, organize the found content into an answer, and put a source link next to the answer. You can also continue to ask along the same topic.

What it saves is the first round of opening and sorting a batch of web pages, not deciding which web pages must be trustworthy for you.

How is it different from traditional search

Traditional searches usually start with a title, abstract and a list of web pages, and you select the web page, read it and spell out the answer yourself. Perplexity reverses the order: gives you a comprehensive answer first, then lets you reference it back to the web page.

When looking up a specific URL, finding the official website entrance, or comparing multiple original pages, traditional search is often more direct; when you are new to a topic and need to see the context first or continue to ask questions, Perplexity's answer format saves steps. It's not that one replaces the other, but the way they access the data is different.

First time using it, follow these five steps to search

1. Write the keywords into a complete question, and add the region, time and purpose, such as "How do individual users in mainland China compare the public prices and space of two cloud disks in 2026?"
2. First check whether the answer covers your conditions. If it is not clear enough, ask additional questions. Don't rush to copy the results.
3. Open the source next to the key sentence and confirm that the page title, publication date, author, and original text really support the sentence.
4. When product capabilities, prices, regulations or health issues are involved, priority is given to finding manufacturers, governments, hospitals or the original paper.
5. Isolate the statements that are still conflicting and let them continue to find the source instead of forcing a definite conclusion.

What problems are suitable for it?

• Quickly understand an unfamiliar concept and get the source material to read next.
• Summarize recent happenings while checking different sources by date.
• Compare the public information of multiple products, but the final price and terms still need to be confirmed on the official website.
• Ask around an uploaded file; long files may only extract relevant parts, and the entire file cannot be read completely by default.
• Use deeper modes such as Research when the problem is complex and more sources are needed. Simple facts do not need to be turned on every time.

Quotation is not an exemption mark

If there are quotes in the answer, it only means that there are sources that can be clicked on. It does not mean that each source is of high quality, nor does it mean that the original source text must support all the sentences compiled by it. Web pages may be out of date, reproduced from one another, or lack context, and the model may connect several pieces of material incorrectly.

The real checking action is: click on the link, find the corresponding original text, and look at the date and scope of application. Medical, legal, financial and major purchasing decisions don't stop at automated answers.
