What is Perplexity AI?
Perplexity is a service launched in 2022 by an American startup of the same name. The original idea is simple: combine a search engine with a conversational assistant. Instead of a list of links, you get a written answer, and every key sentence links back, via a small number, to the page the information came from.
You can then ask follow-up questions, like in a conversation, without restating all the context. Perplexity also suggests related questions to help you dig deeper.
Over time, the service has grown a lot: in-depth research, projects, a choice of AI models from different companies on paid plans, its own browser and tools that can produce documents. But its core hasn’t changed: search fast and show your sources.
How to get started with Perplexity
- On the web: go to perplexity.ai. You can even ask a few questions without creating an account.
- On mobile: download the app for iPhone or Android, with voice search.
- On desktop: there’s an app and a dedicated browser for anyone who wants to build it into their daily routine.
Creating a free account (with an email address, a Google account or an Apple account) lets you keep your history and use projects.
How to search well with Perplexity
Perplexity understands questions in plain language. There’s no need to type the way you would in a traditional search engine (“e-bike price 2026”): ask a real question, with your context.
Ask a complete question
Which e-bike should I get for a 10-mile daily commute in a hilly city, with a maximum budget of $1,500? Give me 3 well-reviewed 2026 models with their pros and cons.
The more context you give (how you’ll use it, budget, constraints), the more relevant the answer.
Specify the location and time period
Perplexity searches the whole world. For topics that vary from country to country, or even state to state (laws, prices, availability), add “in the US” or your state and, if needed, the time period: “since January 2026,” “the rule currently in effect.”
Ask follow-up questions
This is one of the real joys of Perplexity: the conversation keeps going. After a first answer, just follow up: “what about a folding model?”, “which one has the best warranty?”, “where can I test-ride one near Denver?”
Choose your sources
Depending on the interface, you can steer the search toward certain types of sources: the web in general, academic papers, online discussions or financial data, for example. You can also explicitly ask it to favor official websites.
What federal and state incentives can I get for energy-efficient home upgrades in 2026? Use only official US government sources (.gov sites) and give the date of each source.
The different search modes
Quick search
This is the default mode: an answer in a few seconds, with a handful of sources. Perfect for factual, practical questions. On the free version, these searches are virtually unlimited.
Pro Search
Pro Search goes further: it breaks your question down, checks more sources and produces a more complete answer. It’s very limited on the free version and much more available on paid plans.
Research
For a complex question (comparing offers, putting together a file, getting up to speed on a topic), Research mode runs an in-depth, multi-step search and produces a structured, sourced report. It’s very useful before a big purchase, a business decision or a presentation.
Computer
Computer is an autonomous agent that can research, code, create documents, presentations, dashboards and apps, and use connected tools to complete multi-step tasks. It requires an eligible subscription and runs on a credit system: quotas depend on your plan. It’s Perplexity’s answer to people who felt you couldn’t actually “make” anything with the tool.
Organizing your searches with projects
Projects (which replaced the old “Spaces,” migrated automatically) bring together your conversations, Computer tasks, files, instructions and connected tools around a single topic. Every search you run inside a project takes that context into account.
A few project ideas:
- Industry monitoring: news from your field, with your competitors as reference points.
- Buying a home: neighborhood prices, assistance programs, the steps involved.
- School: the sources for a thesis, with your professor’s guidelines.
- Travel: planning a trip, with your dates and wish list.
You can share a project with other people, which is handy for group work.
Fact-checking Perplexity’s answers
Visible sources are Perplexity’s big advantage, but they don’t guarantee the answer is accurate. Perplexity summarizes, and it can get things wrong: misread a page, rely on a shaky source or mix up two pieces of information.
Here’s my four-step method:
- Click the numbers next to important claims to see the source.
- Look at the type of site: official, established media outlet, blog, forum?
- Check the date of the source.
- Make sure the source actually says the same thing as the summary.
For anything involving the law, health or money, always go back to the official source before making a decision. I use exactly the same method with ChatGPT, as I explain in my guide to searching the web with ChatGPT.
Perplexity on your phone
The mobile app is probably the best way to discover Perplexity. You can ask questions by voice, which is really convenient on the go: on the street to find a restaurant that’s open, at the grocery store to compare two products, in the car (while parked) to check a route or a fact.
You can also snap a photo and ask a question about it: a wine label, a plant you don’t recognize, a monument, a device you need the manual for. Perplexity identifies the object and looks up the relevant information, with its sources.
On Android, you can even set it as your phone’s default assistant instead of the usual one. On iPhone, a shortcut or widget lets you launch it with a single tap. And since your history syncs, you can pick up on your computer the searches you started on your phone.

Perplexity in everyday life: four real-world situations
Shopping smarter
Before a purchase, Perplexity is amazing at rounding up reviews and prices in a single question. Ask it to summarize independent reviews, flaws reported by users and current prices, then open the two or three most trustworthy sources. In ten minutes, you’ve done the equivalent of an hour of clicking between websites.
Preparing for a doctor’s appointment
Without ever replacing a professional’s advice, Perplexity can help you understand a term you saw on a prescription or a medical report, and prepare your questions. Ask it to rely only on institutional sources (CDC, NIH, MedlinePlus, hospital websites), then jot down the questions to ask your doctor.
Keeping up with a changing issue
Social Security changes, new short-term rental rules in your city, evolving home energy rebates: for a topic that changes often, create a dedicated project and ask the same question regularly, requesting “the changes since last month.” That way you can follow how things evolve without rereading everything.
Helping a child with a school report
Perplexity is very useful for finding reliable, varied sources on a school topic. The right habit to pass on: use the summary to understand, then read and cite the original sources, never the AI’s answer itself. It’s a great way to teach kids how to check information.
My 13-year-old son is working on a school report about the volcanoes of the Pacific Northwest. Find 5 reliable, age-appropriate sources (educational sites, museums, scientific organizations) and summarize in a few lines what each one offers.
My tips for better searches
After hundreds of searches, here’s what really improves the results:
- Give your context: who you are, why you’re searching, what you already know.
- Ask for a format: table, list, numbered steps, a three-sentence answer.
- Exclude sources you don’t want: “no forums or retail sites.”
- Ask about disagreements: “if the sources disagree, present both sides.”
- Rerun in Pro or Research mode when a quick answer feels shallow.
- Save good searches in a project so you can find and update them later.
Finally, don’t hesitate to combine tools: Perplexity to find and verify, then an assistant like ChatGPT or Claude to turn the results into an email, an outline or a polished document.
Perplexity’s limitations
- Sources aren’t always high quality: forums, blogs or retail sites sometimes slip into the results.
- The summary can distort a piece of information or take it out of context.
- Long-form and creative writing isn’t its strong suit, even though it’s improving.
- Advanced features are limited on the free version.
- Some pages are off-limits: paywalled content, private pages or pages that require a login.
Frequently asked questions
Is Perplexity free?
Yes, the free version offers virtually unlimited basic searches. Pro searches and advanced features are limited without a subscription.
Does Perplexity work in other languages?
Yes, it understands and answers in many languages, and it searches local sources too, especially if you specify a country, such as “in the US.”
Can Perplexity replace Google?
For questions where you want a direct answer, often yes. For finding a specific website or browsing lots of results, a traditional search engine is still more practical.
Are Perplexity’s answers reliable?
They’re verifiable, thanks to the numbered sources, but not infallible. Open the important sources, especially for sensitive topics.
How is it different from ChatGPT?
Perplexity is built for search, while ChatGPT is a general-purpose assistant that can also search. I compare the two in detail in my article ChatGPT vs. Perplexity.
The bottom line
Perplexity is the ideal tool for searching fast, with visible sources. Ask complete questions, specify the location and time period, use Research mode for complex topics and projects for your ongoing files. And keep the key habit: click the sources that matter.
