Perplexity AI in 2026: Search, Browser, Agent, or All Three?
Perplexity used to be a simple AI search box. It's now a search engine, a free browser, a research tool, and a separate agent that can act on your behalf. Here's what each piece actually does.
What Is Perplexity AI?
Perplexity is an AI-powered answer engine. You ask it something in plain language, and it searches the web in real time, reads through multiple sources, and gives you one written answer with footnotes linking back to where each piece of information came from.
The difference from a normal search engine is simple: Google gives you links to read; Perplexity gives you the answer and shows you where it got it, so you can still check the sources if you want to.
What’s the Difference Between Perplexity Search, Comet, and Computer?
Perplexity now has three different products with similar-sounding names. Getting these straight makes everything else easier to follow.
Perplexity Search
This is the original product: the familiar chatbot interface at Perplexity.ai. You type a question and get a structured, real-time cited answer.
It features three tiers: a Free tier with daily limits on advanced models, a Pro tier ($20/month) that scales those limits up, and a Max tier ($200/month) that grants unlimited usage.
Here’s what it can do:
Generate instant, conversational answers backed by live inline web citations.
Organize sources transparently so you can verify facts on the fly.
Support deep-dive follow-up questions while maintaining context.

Comet (Browser)
Comet is Perplexity's dedicated, Chromium-based web browser. It can summarize any page you are on, answer context-dependent questions about what you are looking at, and handle simple multi-step actions like filling out a form or interacting with page elements via the "Comet Assistant."
Computer (Agent)
Computer is an entirely separate agentic system from the Comet browser, and the two are easily confused. Instead of just assisting you on a webpage, Computer is an asynchronous, autonomous agent that runs inside an isolated computing sandbox to complete full, heavy-lifting tasks on its own.
It’s available starting from the Pro plan and above and uses credits for each task you assign it. Some of its notable features include:
Asynchronous Execution: Runs massive, multi-step research workflows completely in the background for hours without needing an open tab.
Native App Integration: Directly accesses and operates within standard desktop environments and tools like Word, Excel, and Outlook.
Isolated Sandbox: Securely executes code, downloads data, and processes documents within its own virtualized workspace.
📌 Search answers questions, Comet is the free browser you use day-to-day, and Computer is the paid agent that goes and does things for you.
What’s New in Perplexity AI in 2026?
If you stepped away for a while, here's what's actually new.
Comet went free. Previously locked behind the $200/month plan. As of March 2026, anyone can use it at no cost.
Computer launched. A new agentic product (February 2026) that coordinates close to 20 different AI models to handle multi-step work on its own.
Model Council launched. Ask one question, get answers from three AI models at once, and compare them side by side. Also launched in February 2026.
Ads are gone. Perplexity tested ads inside answers in 2025, then dropped the idea entirely in February 2026 and went all-in on subscriptions instead.
Deep Research got a major upgrade. It now runs on more advanced models and performs better on independent research benchmarks than it did a year ago.
Publisher content is back in answers. A $5/month add-on called Perplexity Plus (included free with Pro and Max) brings in licensed content from outlets like CNN, Fortune, and The Washington Post.
What Features Does Perplexity AI Offer?
If you look up Perplexity online, you’ll notice people keep talking about specific features. Here’s what they’re referring to.
What People Search | What It Is | How It Works |
|---|---|---|
Perplexity Deep Research | Deep-dive search | Instead of a quick one-shot answer, the AI acts like a research assistant. It tracks down dozens of sources, fact-checks itself, finds where different websites disagree, and writes a giant, detailed report for you. |
Perplexity Labs | Playground | A separate mode for building stuff fast. You tell it what you want, and it will spend 10 minutes coding and researching to build you a working spreadsheet, a custom data dashboard, or a mini web app from scratch. |
Perplexity Spaces | Project folders | Shared or private folders where you can dump your search threads, PDFs, and notes. It’s perfect for keeping a specific project organized or collaborating with a team without losing your history. |
Perplexity Finance | Live stock hub | A special corner for tracking companies. You get live stock charts, market trends, and direct links to actual financial filings so you don't have to hunt down earnings reports yourself. |
Perplexity Shopping | Smart buying guide | Pulls together product specs, prices, and reviews from all over the web into simple comparison cards. If you have a Pro account, you can even buy things instantly right from the search page. |
How Much Does Perplexity AI Cost?
There are now six tiers instead of the few you might remember.
Plan | Price | What it adds |
|---|---|---|
Free | $0/mo. | Cited search, free Comet browser, daily limits on Pro-level searches |
Pro | $20/mo. | Unlimited search, top AI models, Deep Research, Comet Plus and Computer included |
Education Pro | $10/mo. | Similar feature set to Perplexity Pro, but with a generous discount for verified students and educators |
Max | $200/mo | Everything in Pro, Model Council, unlimited Labs |
Enterprise Pro | $40/seat/mo. | Team collaboration, admin controls, security compliance |
Enterprise Max | $325/seat/mo. | Everything in Enterprise Pro, plus top-tier models and premium security features |
For almost everyone, the decision is Free vs. Pro. Max is built for people who specifically want to run heavy research workloads daily. Most users never need it.
Is Perplexity AI Better Than ChatGPT or Google?
ChatGPT, Perplexity, and Google solve different problems, even though they overlap on the surface.
Perplexity | ChatGPT | Google (AI Mode) | |
|---|---|---|---|
Best at | Cited, source-backed answers | Writing, coding, general tasks | Broad search plus AI summaries |
Sources shown | Always, by default | Only with web browsing on | Yes, alongside the answer |
Browser of its own | ✅ Comet | ✅ Atlas | ❌ It's built into Search |
Best for | Research and fact-checking | Creating and building things | Everyday search with AI help |
If you’re comparing this to Google AI Mode, the short version is that Google is built into search itself and used by far more people day-to-day. Perplexity is a dedicated research tool that’s smaller in scale but more focused on showing its sources clearly.
Who Is Perplexity AI For?
If you’re still unsure between using ChatGPT, Claude, Gemini, or any other AI for that matter, here’s where Perplexity excels:
Researchers and writers who want a fast first pass on a topic with sources already attached.
People comparing products before a purchase, since it pulls reviews and specs from multiple sites into one answer.
Anyone fact-checking a claim quickly, since every answer comes with a way to verify it.
Teams doing market or competitive research, using Spaces to keep related searches and files organized in one place.
Power users who want multi-model flexibility, letting you toggle the underlying AI "brain" between Claude and ChatGPT while keeping live web-searching active.
Academics and students who need strict data, using Focus Modes to completely ignore regular blogs and search only peer-reviewed journals.
Academics and students looking for an AI that’s discounted for their specific needs, as Educator Pro costs $10 (vs. other AIs that cost $20 for their equivalent Pro subscriptions).
Professionals creating shareable reports, using Perplexity Pages to instantly format a messy search thread into a clean, standalone article.
High-stakes decision makers using Model Council to query three top-tier AIs at once, getting a unified response that maps out exactly where they agree and conflict.
At one point, Perplexity used to be the go-to tool for fact-checking thanks to its capacity for citing sources right below its answers. It’s still great at it, however tools like Gemini are quickly catching up.
Perplexity is still the clear winner if you want a clean, automatically generated research brief, but it no longer has a monopoly on real-time fact-checking.
