Perplexity AI (perplexity.ai) Review
Perplexity AI (perplexity.ai) is an autonomous conversational answer engine built for researchers, developers, and knowledge workers. It bypasses sponsored links to synthesize direct factual answers from live web sources.
The platform uses an advanced retrieval pipeline that parses user intent and queries authoritative web sources. Every claim includes clickable inline citations, making fact-checking transparent and reliable.
With Pro Search mode and specialized academic filters, users conduct deep multi-step research effortlessly. Developers also leverage the Sonar API to integrate real-time grounded search directly into autonomous agents.
In-depth review: what Perplexity AI (perplexity.ai) actually does
Checked 28 Oct 2026Perplexity (perplexity.ai) is an AI answer engine. It searches the open web in real time and returns a concise answer with numbered citations. You can ask follow-up questions, choose a model, or run a longer research report. Paid plans add more searches, advanced models, file creation, and access to Perplexity Computer.
The company also sells Comet, a Chromium-based browser, and an API for developers. Enterprise plans add seat management, internal knowledge search, and data controls. The Free plan costs $0, and paid plans are billed monthly or annually. The core product is available on the web and in mobile apps.
Features worth knowing
Every answer includes numbered links to the sources Perplexity used. The help center says answers can draw on articles, academic papers, forums, and videos.
Pro Search runs automatically when your plan includes it, with no separate toggle. It breaks a question into steps, reads dozens of sources, and returns a longer answer.
Projects are persistent, shareable workspaces for searches, files, instructions, and tools. Projects hold up to 10,000 files and 5 GB in total, with a 100 MB limit per file, according to Perplexity's help center.
Comet is a Chromium-based browser for Windows, Mac, and Linux. It supports Chrome extensions, bookmarks, page translation, and Perplexity's assistant.
Is Perplexity free?
Yes. The Free plan costs $0 and includes basic searches, citations, three Pro Searches per day, and one Research query per month. It does not include advanced models, image generation, or Comet Assistant queries.
Pro is listed at $17 per month when billed annually. It adds expanded Computer access, 4,000 bonus credits, deep research, top models, model selection, and file and app creation. Max is $167 per month billed annually, with 35,000 bonus credits, 10,000 monthly credits, expert research, and frontier models.
Education Pro costs $10 per month for verified students and educators. Enterprise Pro starts at $40 per seat per month, or $400 per year per seat. The API is pay-as-you-go and billed separately from the web plans.
What is Pro Search?
Pro Search is Perplexity's deeper search mode. It chooses models, crawls multiple sources, and summarizes the results with citations. You can narrow a search to Web, Academic, Finance, or Files, and paid users can switch models.
Pro Search also includes a code interpreter for running and debugging code. Free users get three Pro Searches a day; paid plans get weekly limits that vary by tier. Deep Research is a separate mode that runs many searches and returns a longer report in two to four minutes.
A session starts with a question and continues with follow-ups, and Pro Search keeps the earlier context. Every answer keeps its source list, so you can open a citation and check the underlying page.
What is Perplexity Comet?
Comet is a browser, not a separate chatbot. It is built on Chromium, so most Chrome extensions work, and it runs on Windows, Mac, and Linux. It adds Perplexity's assistant to the pages you visit.
Comet Assistant queries are metered by plan. Free users get none, Pro and Max get monthly limits, Enterprise Pro gets 80 per month, and Enterprise Max gets 800 per month. The official help pages do not list a separate Comet subscription price.
Comet also includes standard browser features such as bookmarks, page translation, and support for most Chrome extensions. Comet installs as a desktop application and updates automatically when you relaunch it.
Can Perplexity be used for team research?
Yes. Projects can hold searches, Computer tasks, files, instructions, and connected tools. A project allows up to 10,000 files, 5 GB of storage, 100 MB per file, and five contributors; organization projects allow up to 9,999 contributors.
Enterprise Pro adds shared Projects, centrally governed File Connectors, and internal file search. The company says enterprise data is never used for model training. Team plans also add seat management and billing controls.
Projects are also where Perplexity keeps long-running Computer tasks. A task can research, build a document or dashboard, and save the result in the project for later use.
Limitations to weigh first
- –The Free plan includes only three Pro Searches per day, one Research query per month, and no Comet Assistant queries.
- –A Project is limited to 10,000 files, 5 GB of storage, 100 MB per file, and five contributors unless it belongs to an organization.
- –Max annual billing is only available on perplexity.ai, and the API is billed separately with no web Pro features or complimentary credits.
