Perplexity AI

Is Perplexity free? Yes. Perplexity is an AI search engine that answers in plain English and cites its sources, and its Free plan costs $0 for limited daily use. Perplexity Pro costs $20 a month, or $17 a month if you pay for a year. Max costs $200 a month, or $167 a month billed yearly. Verified college students and faculty can get Education Pro for $10 a month, and for companies, Enterprise Pro starts at $40 per seat a month ($34 billed yearly).

One catch before you pay anything: make the free account first. Without one, my first question got a full answer with its sources and the next two hit a sign-up wall. My advice: use the free account for a couple of weeks, and only pay for Pro if you keep hitting the limit or you want to choose the AI model yourself. Max is for people who'd live in Perplexity all day. Here's the longer version.

What Perplexity is, and how it differs from a regular chatbot

A regular AI chatbot answers from what it learned during training and looks things up on the web when it needs to. Perplexity turns that around: search is the starting point. The home page is basically a search box under the question "What do you want to know?", with Search and Computer modes along its bottom edge and a Model menu on the right.

The promise is in one line on the Free card, which Pro and Max build on: "Citations in every answer". According to Perplexity, those citations sit inline, so each claim points to the page it came from. That's the whole reason to use it over a general assistant. When the answer lives on the web and changes often (news, prices, product specs, "what's the latest on…"), an answer with its sources attached is worth more than a nicely written one you can't check.

Where it's less of a fit is everything that isn't really a search. For writing, brainstorming or working through your own long documents, I'd reach for a general assistant like ChatGPT or Claude. Different tools, different jobs.

What happened when I tried it without an account

I opened perplexity.ai in a browser set to US English, didn't sign in, and asked how much a US passport renewal by mail costs right now. This time I got a real answer: a short paragraph, a small table of fees and a list of add-ons, with a citation chip on every line pointing to the State Department's travel site and a Sources panel that counted 10 sources. Next to it, a box invited me to sign up for free to save and sync my searches.

Then I opened a fresh session and asked which Utah national parks need a timed-entry reservation this fall. Perplexity researched for a few seconds and replied with one line: "Sign up and repeat your request." A follow-up got the same line, this time behind a "Sign in to continue using Perplexity" pop-up that covered the page. A few weeks earlier it was worse: 4 tries out of 4 ended that way.

I can't tell you the exact rule behind it; it may depend on the browser, the network or simply the day. What I can tell you is what to do about it: create the free account before you decide whether Perplexity is any good. It costs nothing, the free plan on the pricing page is the one you'll be on, and it's the fair way to test it.

Perplexity pricing: Free, Pro, Max and Enterprise

Here are the plans in US dollars. The cards on the pricing page show Pro and Max at their billed-annually prices, so $17 and $167 are the only prices it shows. Paid monthly, Pro is $20 (its in-app price in the US App Store) and Max is $200 (the help center gives $200 a month or $2,000 a year, with yearly billing on the website only).

The comparison table under the cards fills in the gaps. On Free, answers from the web, file uploads and asset generation are all marked "Limited", and video generation isn't there at all. Pro has all of them. Max marks web answers, uploads and assets as "10x" and video as "5x", and the comparison table ticks Model Council for Max only. The FAQ says Max includes "several Model Council runs per month" and calls it the plan for "heavy, sustained work".

On models, the FAQ says Perplexity picks the best one for each question from several, including ChatGPT, Google Gemini, Anthropic Claude and NVIDIA Nemotron. Pro and Max let you choose a preferred model yourself; Free doesn't. For companies there's a third Enterprise option with custom pricing, for extra security and governance.

Computer, and what its credits cost

The second card on the home page is the newer one: "Get work done with Computer", tagged NEW, with the line "Hand off your projects to get polished, reliable deliverables around the clock." In plain English, Computer is Perplexity's step from answering to doing, closer to an AI agent like Manus than to a search engine.

It's also what separates the plans the most, and it runs on credits. Fair warning: this is the slightly technical part. According to the help center, 100 credits equal $1, and only Computer uses them: regular searches don't. Free doesn't include Computer at all. Pro doesn't come with a monthly pot of credits: new subscribers can get a limited-time, one-time bonus of 4,000 credits that expires in about 30 days, and Perplexity says paid Pro plans also include some Computer use every week, a feature it's still rolling out. Max comes with 10,000 credits a month plus a one-time bonus of 35,000.

How far does that go? The help center gives typical ranges, and says your own jobs may use more or less:

So Max's 10,000 monthly credits are $100 worth of Computer work: at least 10 typical research reports, or one big dashboard. If you need more, you can buy credits; in the US App Store, 500 credits cost $5.

Is Perplexity free?

Yes, with two catches. The first is the one from my test: in practice, you'll want an account, because without one you may get a sign-up request instead of an answer. The second is the limit. The Free card only says "Good for limited daily usage" and "Better for simple questions". The help center is a little more specific: practically unlimited basic searches, but only 3 Pro Searches a day and 1 Research query a month, and no Computer.

That's the plan's own pitch: simple questions, the kind you'd otherwise type into a search box. Perplexity also says it will always keep a free version, and that it includes Comet, its own web browser for Mac, Windows, iOS and Android. If Perplexity becomes your default search and you start running into the limit, that's the moment to look at Pro.

Is Perplexity Pro worth $20?

For regular users, yes. Pro is where the "Limited" labels in the comparison table disappear: you get deep research, you can pick the model instead of letting Perplexity choose, and you get Computer access, video generation and connections to your apps. $20 a month ($17 on a yearly plan) is about what a lot of people already pay for one AI subscription, so the real question is which tool you'd open every day. If your day is mostly questions that need sources, Pro is the $20 I'd look at first. If your day is mostly writing, it isn't. And if you're a college student or faculty member, check Education Pro first: it's the same Pro at $10 a month once you're verified.

Max is a different story. At $200 a month ($167 billed yearly), 10 times Pro, it only makes sense if Computer is doing real work for you every day or you need the highest limits for research. For almost everyone else, Pro covers it.

Who it's for, and who should skip it

It's a good fit if you look things up all day and care where the answer comes from: students writing papers, researchers, journalists, analysts, or anyone who's tired of opening ten tabs to answer one question.

Pro is worth a look if you already use the free plan every day and keep running into the limit, or if you want to try several top models without paying for each assistant separately.

Skip it if what you mostly do is write emails, brainstorm or work with your own files. A general assistant is built for that. And if what you want is a finished report or a built project rather than an answer, an agent is the better starting point.

Perplexity or something else?

If you want an all-rounder for chatting and writing, ChatGPT is the one to try. For long documents and careful writing, I'd compare Perplexity against Claude. And if your question is really a task, like "research this and turn it into a report", Manus is built to carry the whole job out on its own, paid in credits. And if what you want is answers that also search X as it happens, Grok does live web and X search, free once you have an account, with paid plans from $8 a month.

If what you need is a quick answer you can check, give Perplexity a proper try. Just sign in first.
