For more than two decades, searching the internet has followed roughly the same routine.
Type a few words into a search box. Receive a page filled with links. Open several tabs. Read through them. Close the irrelevant ones. Then piece together the answer yourself.
Perplexity is trying to change that.
The artificial intelligence-powered search platform has emerged as one of a new generation of tools challenging the traditional idea of what an internet search should look like.
Instead of simply pointing users towards websites that might contain an answer, Perplexity searches the web, reads information from multiple sources and produces a direct response.
Crucially, it also tells users where that information came from.
That seemingly small difference helps explain why Perplexity is attracting attention among students, researchers, professionals and everyday internet users.
What is Perplexity?
Perplexity is an AI-powered search engine, sometimes described as an “answer engine”, that searches the internet and uses artificial intelligence to provide direct answers to questions.
Ask Perplexity a question and, rather than returning the familiar page of blue links associated with conventional search engines, it typically produces a written response accompanied by citations to the websites and sources it used.
The company describes its service as an AI-powered search engine that searches the web in real time and delivers conversational answers backed by verifiable sources.
In practical terms, imagine asking:
“What are the best places to visit in Japan in November?”
A conventional search engine might return travel blogs, tourism websites, Reddit discussions, videos and sponsored results.
Perplexity attempts to do some of that reading for you.
It searches for relevant information, analyses the sources and then produces an answer summarising what it found. Citations within the response allow users to open the original sources and investigate further.
This combination of search engine and AI assistant is at the heart of Perplexity’s appeal.
Why are people using Perplexity?
The answer may be surprisingly simple: it can save time.
Traditional internet search is extremely powerful, but finding an answer can involve a surprising amount of work.
Someone researching a complicated subject may open five, ten or even twenty webpages before feeling confident that they understand it.
Perplexity tries to compress that process.
Instead of asking users to assemble the information themselves, it attempts to provide a useful starting point immediately.
For simple questions, the difference may be minor.
For more complicated research, it can be substantial.
A traveller could ask:
“Plan a seven-day trip to Switzerland in December for a family that doesn’t want to drive.”
A business owner could ask:
“What factors should a small company consider when choosing accounting software?”
A student might ask:
“Explain inflation and interest rates to me using a simple example.”
These are not necessarily searches that fit neatly into three or four keywords.
They are questions.
And that is an important distinction.
From keywords to conversations
Google taught an entire generation how to speak to a search engine.
People learnt to strip their questions down to keywords:
“Tokyo weather November.”
“Best laptop 2026.”
“Singapore renovation cost.”
AI search engines are encouraging almost the opposite behaviour.
Users can increasingly type questions the way they would ask another person.
“I’m travelling to Tokyo in the second week of November. What weather should I expect, and what clothes should I pack?”
Perplexity can answer the initial question and then allow the user to continue.
“What if I’m also going to Hokkaido?”
“Will I need waterproof shoes?”
“What about a child?”
Because the conversation retains context, users do not necessarily need to begin another search from scratch.
Search begins to feel less like operating a database and more like conducting a conversation.
Why Perplexity’s citations matter
Perhaps the most distinctive part of the Perplexity experience is something decidedly unglamorous: footnotes.
AI systems can make mistakes.
They can misunderstand questions, rely on questionable information or confidently present something that turns out to be incorrect.
Perplexity does not eliminate that problem.
What it does provide is a relatively convenient way of checking where an answer came from.
Its responses generally contain citations linking users to the underlying sources.
That means someone researching an important subject can read the AI-generated summary and then inspect the original material.
For casual searches, users may never click them.
For financial, academic, professional or other consequential research, those citations can become considerably more important.
It is also why Perplexity should be treated as a research starting point rather than an unquestionable authority.
The source still matters.
Is Perplexity the same as ChatGPT?
Not quite.
The two products increasingly overlap, but they developed with somewhat different identities.
Perplexity has positioned itself strongly around search and research. Its core experience revolves around finding information from the web, synthesising it and displaying the sources alongside the answer.
ChatGPT is a broader AI assistant that can be used for tasks ranging from writing and brainstorming to analysis, coding, research and working with files.
Perplexity itself describes its platform as an AI answer engine.
The easiest way to understand the distinction is not to think of one as replacing the other.
Instead, think of them as part of a much larger shift in how people interact with information online.
What can you use Perplexity for?
The platform is particularly suited to questions that would otherwise require searching through several websites.
Common uses include:
- researching a product before buying it
- comparing products or services
- planning holidays
- understanding current events
- researching companies and industries
- finding academic information
- learning unfamiliar subjects
- summarising complicated topics
- conducting professional research
- discovering sources for further reading
Perplexity also offers more advanced search and research features.
Its Pro Search function is designed for questions requiring deeper research across multiple sources, while its Research mode can perform numerous searches and analyse a much larger body of information before producing a report.
That makes the platform considerably more ambitious than a chatbot answering trivia questions.
Why not just use Google?
For many searches, Google remains perfectly useful.
If you want the official website of a restaurant, directions to a shopping centre or the telephone number of a business, receiving a list of webpages may be exactly what you want.
But consider another search:
“Which neighbourhood should I stay in when visiting Seoul with elderly parents if I want restaurants nearby and minimal walking?”
There probably isn’t one webpage containing the perfect answer.
You need to consider transportation, geography, hotels, restaurants and the experiences of other travellers.
This is where AI-assisted search becomes interesting.
Instead of merely finding documents containing your keywords, the system attempts to research the question itself.
The distinction can be summed up simply:
Traditional search engines help you find information. AI answer engines try to help you understand it.
Perplexity still gets things wrong
The convenience comes with an important warning.
An answer accompanied by citations can look authoritative even when it contains errors.
Sources can be outdated. An AI system can misinterpret what a webpage says. Different sources may contradict one another. Important context can disappear during summarisation.
Users should therefore be particularly cautious when researching subjects involving money, health, law or other significant decisions.
If Perplexity provides information about a financial product, for example, the sensible next step is to check the financial institution’s official information and applicable terms rather than making a decision solely from an AI-generated summary.
The same principle applies to government regulations, medical information and legal matters.
AI can dramatically accelerate research.
It does not remove the need for judgement.
The bigger story isn’t really Perplexity
Perplexity is interesting, but the more important story may be what it represents.
For years, websites competed for a user’s click.
Search engines acted as enormous indexes pointing people towards information elsewhere on the internet.
AI search introduces another possibility.
The search engine itself can read those webpages and construct the answer.
That changes the relationship between search engines, publishers and users.
People may increasingly expect to ask complicated questions and receive organised explanations rather than lists of websites.
It could also change how businesses think about being discovered online.
A company may no longer be competing only to appear near the top of a search results page. Increasingly, businesses and publishers may also want their information to be sufficiently useful, authoritative and accessible that AI systems recognise it as a source.
That is a significant change.
Is Perplexity free?
Perplexity offers a free version that is sufficient for many everyday searches.
The company also offers paid plans, including Perplexity Pro, which provide greater access to advanced search and research capabilities, additional AI models, file analysis and other features.
For someone curious about AI search, however, there is little need to begin with a paid subscription.
The basic experience demonstrates the concept rather quickly.
Ask a question.
Read the answer.
Check the citations.
Then ask a follow-up.
Within a few searches, it becomes obvious why the format has attracted attention.
Is Perplexity going to replace Google?
Predictions of Google’s demise have accompanied almost every major development in internet search.
It would be premature to make another one.
What does appear increasingly plausible is that the definition of “searching” is changing.
Sometimes people want websites.
Sometimes they want directions.
Sometimes they want products.
But very often, what people actually want is an answer.
AI-powered platforms such as Perplexity are betting that users will increasingly prefer to ask the internet a complete question and have technology perform much of the searching, reading and summarising on their behalf.
Whether Perplexity ultimately becomes a household name is almost secondary.
It has already helped demonstrate a different way of navigating the world’s information.
After decades of learning how to search the internet, we may be entering an era in which the internet increasingly searches itself for us.
Perplexity vs ChatGPT: What’s the Difference?
For many people encountering Perplexity for the first time, there is an obvious question: How is Perplexity different from ChatGPT?
At first glance, the two can look remarkably similar.
Both allow you to type questions in everyday language. Both can explain complicated subjects, summarise information and respond to follow-up questions. Both can also search the web and provide links or citations to online sources.
The difference is less about what they can do and more about what they were primarily designed to do.
Perplexity is built around search and research. ChatGPT is a broader AI assistant that also has powerful search and research capabilities.
Think of Perplexity as an AI search engine
Perplexity describes itself as an “answer engine”.
When you enter a question, Perplexity searches the web for relevant information, analyses what it finds and produces a direct answer with citations to the original sources.
The sources are a prominent part of the experience.
This makes Perplexity particularly appealing when your main objective is to find information, research a subject or quickly understand what multiple websites are saying about something.
For example, you could ask:
“What are the latest changes to Singapore’s property market and what are analysts saying about prices?”
Perplexity can search for recent information, combine findings from different sources and present an answer with citations that you can inspect yourself.
ChatGPT is designed to do much more than search
ChatGPT can now perform many of those same research tasks.
It can search the web for current information, provide citations and conduct deeper research across multiple sources.
But search is only one part of what people use ChatGPT for.
Someone might use ChatGPT to research a subject and then immediately ask it to turn that research into a presentation, analyse a spreadsheet, explain a document, brainstorm a business strategy, help with coding, plan a holiday or rewrite a difficult email.
In other words, Perplexity’s identity begins with finding information, while ChatGPT’s identity is that of a more general-purpose AI assistant.
A simple way to understand the difference
| Perplexity | ChatGPT | |
| Best known for | AI-powered search and research | General-purpose AI assistance |
| Searches the web | Yes | Yes |
| Provides sources | Yes, citations are central to the experience | Yes, when using web search and research |
| Follow-up questions | Yes | Yes |
| Researching current information | A major focus | A major capability |
| Writing and brainstorming | Available | Major strength |
| Working across many different tasks | Increasingly capable | Core part of the product |
| Best suited to | Finding, researching and verifying information | Research plus creating, analysing, reasoning and completing broader tasks |
The distinction is becoming less clear as both platforms add new capabilities.
Perplexity has expanded beyond simple web searches, while ChatGPT has become considerably more capable as a search and research tool.
For the average user, there is no reason to treat it as an either-or decision.
