Perplexity AI: The Search Engine That Provides Complex Answers Instead of Links
When four former OpenAI, Meta, and Databricks researchers decided in 2022 to build an alternative to Google, many people were sceptical. Today, in 2026, Perplexity AI has more than 45 million active users, an estimated valuation of nearly USD 22 billion, and represents a fundamentally different approach from traditional search engines: instead of presenting ten links, it delivers a single, well-supported answer.
In this article, we explore how Perplexity AI works, what subscription plans are available in 2026, where it is stronger and weaker than OpenAI ChatGPT, and how it can be used effectively — including in Hungarian.
What Is Perplexity AI?
Perplexity AI — often searched for simply as AI Perplexity — is an AI-powered answer engine.
The word perplexity in everyday English means confusion or uncertainty. However, in mathematics and natural language processing (NLP), it is also a technical metric used to measure how “uncertain” a language model is when interpreting text. The lower the perplexity score, the better the model understands and predicts the next word — meaning the more accurate its language comprehension is.
The founders chose the name deliberately: the goal of Perplexity AI is precisely to eliminate uncertainty. Instead of presenting users with ten different links and leaving them to piece together the truth themselves, the platform summarises, organises, and delivers information in a structured way supported by sources.
How Was Perplexity AI Founded?
Perplexity AI was founded in August 2022 in San Francisco by Aravind Srinivas (CEO), Denis Yarats (CTO), Johnny Ho, and Andy Konwinski. The founding team previously worked at organisations such as OpenAI, Meta FAIR, Quora, and Databricks, bringing together expertise in AI research, large-scale systems, and search product development.
The search engine officially launched on 7 December 2022. Just two months later, in February 2023, the platform had already attracted two million unique visitors. By early 2024, the company had completed four funding rounds. In June 2025, a USD 500 million investment round valued the company at USD 14 billion, and by early 2026 this valuation had reportedly risen to approximately USD 21–22 billion. Investors include names such as Jeff Bezos, Nvidia, SoftBank Vision Fund 2, and Databricks.
In May 2025, the platform processed approximately 780 million queries per month — around 30 million per day — and answered more than 10 billion questions throughout 2025. By early 2026, annual recurring revenue (ARR) had reportedly approached USD 200 million.
Reinventing Search: How Does Perplexity AI Work?
Traditional search engines — such as Google and Microsoft Bing — display a list of relevant webpages. Users then need to click through, read, and compare the information themselves. Perplexity AI takes a fundamentally different approach: it synthesises information from multiple sources in a single step and generates a direct answer while also citing where the information comes from.
1. Understanding the Question
Users can type naturally — in either Hungarian or English. The system uses natural language processing (NLP) to analyse intent and context.
2. Real-time web search
Through its proprietary Sonar search engine, Perplexity AI queries the internet in real time, including news articles, scientific papers, technical documentation, and live data feeds. This is one of the key differences compared to simple chatbots: it does not rely solely on training data.
3. Synthesis and response generation
The model processes the collected sources, filters out redundant or potentially misleading content, and generates a structured, summarised answer.
4. Source-Cited Output Format
Each major statement is accompanied by numbered citations linking directly to the original sources. With a single click, users can verify the information and explore the topic in greater depth.
5. Continuous Conversational Context
Perplexity remembers the context of the conversation thread, allowing users to ask follow-up or clarifying questions without having to restate the entire topic.
The main features of Perplexity AI
Now let’s take a closer look at what Perplexity AI can actually do.
Quick Search and Pro Search
- Quick Search: Provides concise, source-backed answers within seconds. Ideal for casual queries and quick fact-checking.
- Pro Search: A deeper research mode that refines questions conversationally, analyses multiple sources, and generates more detailed and structured responses. The free plan includes five Pro Searches per day.
Deep Research
The Deep Research mode is designed for complex research tasks involving multiple parallel sources. It independently searches, compares, and synthesises information before generating a longer, structured research report — similar to a condensed analyst or researcher briefing. The Pro plan includes up to 20 Deep Research queries per day.
Model Council
Introduced on 5 February 2026, the Model Council feature allows users to compare outputs from multiple large language models — such as GPT-5.2 and Claude 4.6 — for the same question simultaneously. This is especially useful when comparing accuracy, reasoning styles, or analytical approaches.
Spaces – research workspaces
The Spaces feature allows users to create dedicated research workspaces where documents, webpages, and previous search threads can be uploaded and used as shared context. In team environments, these workspaces can be shared and collaboratively edited.
Perplexity Pages
Research results can be turned into shareable, publishable pages through the Pages feature. This is useful for publishing knowledge-base entries, summaries, and internal reports.
File and document analysis
Starting from the Pro plan, Perplexity AI can analyse PDFs, spreadsheets, and images. Uploaded documents are treated as contextual input, allowing the system to generate summaries, key insights, and comparisons.
Perplexity Computer – autonomous AI agent (Max plan)
Introduced on 25 February 2026, Perplexity Computer is a cloud-based AI agent that coordinates 19 different models — including Claude Opus 4.6 (primary reasoning engine), GPT-5.2 (broad search and long-context processing), Gemini (deep research), and Grok (fast task execution) — to autonomously complete complex multi-step workflows. It can browse the web, analyse documents, manage emails, fill in forms, and carry out entire research processes independently. This feature is available exclusively in the Max plan.
Perplexity AI Comet browser
Comet is Perplexity’s own AI-powered browser, launched in early 2026 (with iOS support arriving in March 2026). It offers built-in page summarisation, research tools, and autonomous task execution — including bookings, email handling, form completion, and webpage translation — without leaving the browser environment. The Perplexity AI Agent can also issue commands directly to Comet.
Sonar API – for developers
The Sonar API is compatible with the OpenAI API ecosystem. Applications already using the OpenAI API can switch to Sonar simply by changing the base URL and model name. Pricing is usage-based, with no monthly minimum commitment (starting from USD 1 per million input tokens).
Incognito mode and voice search
In Incognito Mode, Perplexity AI does not log search history, making it useful for research involving sensitive topics. The mobile app also supports voice search, allowing users to ask questions verbally while receiving text-based responses.
In Which Areas Is Perplexity AI Most Useful?
Perplexity AI performs particularly well in situations where fast, reliable, and source-verifiable information is required. The most common use cases include:
Research and competitor analysis
- Rapid synthesis of professional and scientific articles, including the extraction of key findings.
- Market research and competitor analysis based on real-time information and current web data.
- Comparing multiple sources within a single query while identifying inconsistencies and differing viewpoints.
Content and document creation
- Creating blog articles, reports, and summaries based on well-grounded research materials.
- Analysing, summarising, and structuring existing documents such as PDFs and spreadsheets.
- Quickly preparing presentation outlines and briefing analyses.
Everyday Productivity and Decision Preparation
- Fast fact-checking and processing of current news and developments.
- Supporting travel planning, product evaluations, and purchasing decisions.
- Helping users quickly understand complex topics in a way that remains accessible even for non-experts.
For Developers – Sonar API Integration
Using the Sonar API, developers can integrate Perplexity AI search and answer-generation capabilities into their own applications. The API is compatible with the OpenAI ecosystem, meaning migration requires only minimal code changes. According to 2025 benchmark tests, the Sonar Pro API achieved an F-score of 0.858 on SimpleQA factual accuracy evaluations, outperforming most competing APIs in answering straightforward factual questions correctly.
Perplexity AI vs. ChatGPT vs. Google – Which One Is Best for What?
This is one of the most frequently searched comparisons. While the three tools may appear similar on the surface, they are designed for fundamentally different purposes.
TOOL | STRENGTH | Weakness | When to choose? |
|---|---|---|---|
Perplexity AI | Real-time, source-backed research and fact-checking. In 2025, it answered more than 10 billion questions. | Creative writing and longer conversational interactions are less advanced. | For up-to-date, verifiable research, market analysis, and fact-checking. |
ChatGPT | Writing, coding, creative tasks, and longer conversations. | By default, it does not search the internet in real time. | For creative work, coding tasks, or extended conversational interactions. |
Google Search | Fast link-based search results with an extremely broad source base. | Users must read and synthesise the information themselves. | When you want to evaluate original sources directly on your own. |
DeepSeek | Strong reasoning and coding capabilities. | Does not search the web in real time. (Note: available as a model option within Perplexity Pro.) | For complex logical reasoning and coding-related tasks. |
In short: For fresh, verifiable research, Perplexity is the best choice; for creative work, coding, or longer conversational tasks, ChatGPT is generally stronger, while Google remains the best option for quickly browsing lists of links and original sources.
Perplexity AI in Hungarian – Does It Work Reliably?
Yes, Perplexity AI can also be used in Hungarian. For simpler tasks — such as fact-checking, summaries, and shorter research queries — both Quick Search and Pro Search reliably understand and answer questions in Hungarian.
For more complex, multi-step Deep Research tasks, results are currently more accurate and detailed in English. A common workflow is to write prompts in English first and then ask the system to translate the output into Hungarian as a follow-up step.
The platform is available through the browser at perplexity.ai as well as through iOS and Android mobile applications. On Windows, it can also be installed via the Microsoft Store. Hungarian voice search is also supported in the mobile application.
Using Perplexity AI step-by-step
Perplexity AI can be tried without registration directly on the perplexity.ai website. However, registering is recommended for full functionality, as it enables saving previous conversation threads and storing personal settings.
Steps:
- Open the perplexity.ai website or download the mobile app (iOS / Android).
- Register using a Google account or email address — or continue without registration.
- Enter a question or research task (including in Hungarian).
- Choose between Quick Search (fast) and Pro Search (detailed) modes.
- Review the cited sources in the footnotes and ask follow-up questions if needed.
Perplexity AI and Data Privacy
In the Free and Pro plans, Perplexity AI logs search history by default, although this can be disabled using Incognito Mode. The Enterprise Pro plan is SOC 2 certified, and organisational data is not used for model training purposes. In February 2026, Perplexity discontinued its advertising-based business model and moved entirely to a subscription-based revenue structure — a change the company justified as a way to preserve user trust.
The Perplexity Computer agent requires explicit user approval for sensitive actions such as payments or data submission. It is also worth noting that Perplexity AI has previously faced legal scrutiny regarding content usage practices involving organisations such as the BBC, Dow Jones, and The New York Times. Since then, the company has introduced a publisher revenue-sharing programme.

Perplexity AI FAQ
Finally, let’s look at a few more frequently asked questions about Perplexity AI!
What Is Perplexity AI Useful for in Everyday Search?
results, we want an immediate, ready-made answer. For example: “What are the key changes to Hungarian personal income tax regulations in 2026?” Perplexity summarises the essential information and cites the sources directly, removing the need to read multiple separate articles. Other common use cases include quickly researching competitors, comparing products before making a purchase, extracting the key findings from professional articles, or rapidly processing breaking news and current developments. Compared to traditional search engines, the main advantage is not the number of results, but the fact that the synthesis work is done for us automatically.
How to Write Effective Prompts When Using Perplexity AI
The more precise the question, the more useful the answer will be. A few proven best practices: provide context (“I’m looking for this as a marketing manager…”), specify the desired format (“List the points in bullet form!” / “Write a short summary!”), and use Pro Search mode if you need deeper analysis. Example of a weak prompt: “AI tools.” Example of a stronger prompt: “Which AI tools should a 10-person marketing team use in 2026, and how much do they cost?” Refining the request afterwards also works well: if the first response is not detailed enough, simply ask a follow-up question such as: “Expand the second point with specific examples.”
What Is Perplexity AI Deep Research, and When Should You Use It?
Deep Research is the most advanced research mode within Perplexity AI. It searches through dozens of sources in parallel and then generates a structured research report based on the collected information. It is best used when exploring complex questions in depth — for example, for competitor analysis, mapping industry trends, or supporting strategic decision-making. The feature is available from the Pro plan onwards (with up to 20 queries per day) and typically takes between one and three minutes to complete. In return, it provides significantly more detailed and comprehensive output than standard search modes.
How Reliable Is Perplexity AI, and How Should You Verify Its Sources?
Perplexity AI attaches numbered source references to its statements — by clicking on them, users can open the original article or webpage. However, reliability is not automatic: the system is only as strong as its underlying sources. Typical issues may include outdated information in rapidly changing topics, weaker source coverage in niche subject areas, and occasional inaccuracies in synthesis. A practical verification routine is to review the first two or three cited sources, check publication dates, and — for important decisions — always read the original material rather than relying solely on the generated summary.
Perplexity AI Login Problems – Why Can’t I Sign In?
The most common causes are browser settings blocking cookies or third-party content (often due to VPNs or privacy extensions), external access restrictions connected to Google or Apple account sign-in, or network firewalls on work or school-managed devices blocking the perplexity.ai domain. Typical troubleshooting steps include trying to log in via Incognito Mode, temporarily disabling VPN services, or using email-based registration instead of Google account authentication. If the device is managed by an organisation, contacting the IT team is usually recommended.
Is There a Perplexity AI Mobile App, and How Does It Differ from the Web Version?
Yes, free mobile applications are available for both iOS and Android. The biggest advantage of the mobile app is voice search, allowing users to ask questions verbally — especially convenient while travelling or multitasking. The web version, however, is generally stronger for longer research sessions, where Deep Research and Labs features are more reliable and easier to manage. Subscription tiers remain synchronised across platforms, but mobile billing is handled through the App Store or Google Play, meaning cancellations must also be managed through those platforms.
How Can You Create Source-Cited Summaries with Perplexity AI?
Perplexity AI automatically includes source references by default, but for more structured summaries it is worth using explicit prompts. Example: “Write a 300-word summary about [topic], and cite the source after each statement using numbered references.” In Pro Search mode, the system processes more sources and produces deeper synthesis. Deep Research mode generates even more detailed reports, which can also be exported, while on-page citations remain clickable and saveable as links. Important: if the generated summary is used in academic or professional materials, always verify the original sources and cite them according to proper citation standards — not Perplexity itself, but the original referenced source.
What Are the Best Perplexity AI Alternatives in 2026?
The best alternative depends on the intended use case. For real-time research and fact-checking, similar tools include You.com and Microsoft Copilot, the latter being free and also providing cited sources. As general-purpose AI assistants, OpenAI ChatGPT (for writing and coding) and Anthropic Claude (for longer documents and nuanced analysis) are often considered stronger. For developers seeking alternatives to the Sonar API, Tavily API is another commonly considered option. If pricing is the main concern, the free version of Perplexity AI already covers most basic needs — upgrading to Pro generally only becomes worthwhile for regular and intensive research workflows.
