Perplexity vs ChatGPT: A detailed comparison of two leading AI assistants.

Most AI chatbots today offer a fairly similar experience. Although they use different AI models behind the scenes, the process remains almost the same whether using ChatGPT, Claude, or Gemini: the user inputs a command (prompt), and the AI ​​generates the response. This is what makes Perplexity particularly interesting.

Instead of just another chatbot, Perplexity is positioned as an alternative to traditional search engines and an all-in-one research assistant. Unlike many competing AI chatbots, Perplexity focuses on real-time search results with reliable citations.

In particular, after the launch of Perplexity Computer, the platform also possesses AI agent capabilities that can automatically perform multi-step research tasks and many other complex jobs.

So how can Perplexity compete with ChatGPT – the most popular and heavily invested AI assistant currently available?

In this article, let's explore the key differences between Perplexity and ChatGPT , as well as advice on which AI chatbot to choose.

A quick comparison of Perplexity and ChatGPT

Price	Free, Pro $20/month, Max $200/month	Free, Go $8/month, Plus $20/month, Pro $200/month

Perplexity vs ChatGPT: Which is the better AI chatbot?

ChatGPT is a versatile AI assistant capable of web searching.

ChatGPT is a prime example of what modern AI chatbots can do. Since its launch in 2022, the platform has continuously pushed the boundaries of large language models (LLMs) and multimodal models (LMMs), quickly becoming an extremely powerful work support tool.

With ChatGPT, users can collect data from the Internet, analyze data, create interactive charts, write and deploy applications, and program with the Codex.

To date, Perplexity has also added many features such as task scheduling, image recognition via camera, file processing, and AI Agent with Perplexity Computer.

However, ChatGPT remains a more versatile AI assistant thanks to features such as:

1. Canvas is used for editing documents and source code.
2. Custom GPT is a user-created file.
3. ChatGPT Agent performs tasks on the web.
4. ChatGPT Apps connect with enterprise applications.

While ChatGPT is an "all-in-one" tool, Perplexity is built around real-time search. Despite its chatbot-like interface, Perplexity's primary goal is to be an answer engine, providing constantly updated answers from trusted sources.

When it first launched in late 2022, Perplexity's idea of ​​combining AI with web search was quite novel. While ChatGPT, Google AI Mode, and many other chatbots now offer similar features, Perplexity still delivers superior search quality.

For example, with the question: "What is the latest news about NASA's Mars rover?" , ChatGPT compiles information from about two dozen sources, including less reputable ones like the New York Post or SlashGear, and sometimes doesn't automatically search the web unless the user has enabled Search.

Meanwhile, Perplexity primarily uses sources from NASA and scientific journals with clearer presentations, provides hints for follow-up questions, and offers one-click Deep Research support.

For questions about news or factual information, Perplexity often provides more complete and reliable results. Another advantage is that users can choose the AI ​​model used to answer, including GPT, Claude, Gemini, Nvidia, Sonar, or let Perplexity automatically select a suitable model.

Perplexity is a better research assistant.

ChatGPT can search the web and generate research reports, but it still has some limitations when conducting in-depth research, such as difficulty in knowing the source of information and not always prioritizing reputable sources.

Perplexity excels due to its citation system and numerous specialized research tools. For example, if conducting academic research, users can utilize Perplexity Academic to ensure that citations in their research come only from academic sources. Perplexity also provides specialized research environments for fields such as finance, patents, and tourism.

For business users, Perplexity's new Premium Sources feature provides access to data that is typically limited by fees, such as Statista (market information), PitchBook (investor data), and CB Insights (startup analytics).

Additionally, there's Model Council, available only to Max subscribers. Instead of relying on a single model to answer a crucial question, Model Council runs queries on multiple leading models simultaneously and shows where they are similar and different. A question is answered by multiple AI models at the same time, and then the system synthesizes the similarities and differences.

Furthermore, there is an advanced version of Deep Research - Create Files and Apps, which can collect images, create charts, synthesize documents, and present them as visual reports.

AI Agent is the next direction of development for both platforms.

More and more companies are developing AI Agents – AI capable of performing tasks automatically for users. Perplexity currently has Comet Browse and Perplexity Computer, while ChatGPT has Atlas Browser and ChatGPT Agent.

Perplexity Computer

Up to 19 different AI models can be combined to complete a project. For example, when asked to build a meditation application:

1. AI designs the interface itself.
2. Write the code.
3. Create a sound system.
4. Complete the entire application in approximately 8 minutes.

ChatGPT Agent

Focus more on tasks performed online, such as:

Compare products.

1. Book movie tickets.
2. Order pizza.
3. Fill out the form.
4. Buy online.

However, AI Agents are still quite slow and sometimes struggle with websites that have anti-bot mechanisms.

The prices of the two platforms are quite similar.

Both Perplexity and ChatGPT have:

1. Free version.
2. The package costs $20 USD/month.
3. Premium package: $200/month.

The difference is that ChatGPT also offers the ChatGPT Go package - $8/month, suitable for users who need more usage but don't want to upgrade to Plus.

One advantage of Perplexity is that with just one subscription, users can access many leading AI models.

However, it's also worth noting that usage limits frequently change, and the list of supported models can change unexpectedly. Perplexity often prefers using their own Sonar model over more powerful models.

Should you choose ChatGPT or Perplexity?

Users should choose Perplexity if:

1. We need a professional research assistant.
2. We want to perform real-time searches.
3. Clear sources are required.
4. Academic research, finance, or patents.
5. I want to access data for a fee.
6. Want AI to support the entire research or application development project.

And choose ChatGPT if:

1. Want a versatile AI assistant?
2. Write content regularly.
3. Data analysis.
4. Programming.
5. Create images using AI.
6. Use Canvas, Custom GPT, or ChatGPT Agent.

If the primary need isn't in-depth research, ChatGPT remains a more comprehensive option. However, if the work requires reliable information retrieval and specialized research, Perplexity is a more worthwhile tool to consider.
