There are various AI models available on the market, and many people choose to purchase premium access to one of them. Not sure which AI chat is the best and how they differ from each other? We compare Perplexity vs Chat GPT vs Gemini!

What is artificial intelligence? It’s not just GPT Chat!

Artificial intelligence is a very broad field that is not limited to the GPT Chat and similar solutions that we are all familiar with.

It focuses on systems that are capable of mimicking human intelligence. These types of solutions are responsible for decision-making, evaluation, pattern recognition or natural language processing.

The latter is the basis for chats with artificial intelligence, which are used by more and more people around the world. LLM (Large Language Models) are the core of, among others, GPT Chat. They specialise in processing and analysing gigantic text collections in order to reason and respond in a human way.

The main uses of LLM are:

  • content generation (e.g. writing articles, essays, descriptions for posts, etc.),
  • code creation (e.g. simple Python scripts, generating complete applications, etc.),
  • machine translation (e.g. translating documents or texts taking into account the context),
  • sentiment analysis (classification and identification of the tone of voice, emotional character of the text, context, etc.),
  • chatbot creation (e.g. for automated customer conversations)

The artificial intelligence models we use on a daily basis owe their abilities to LLM. Thanks to them, the chat will not only try to understand the context and emotions on its own, but it will also most likely do many time-consuming tasks for you.

Chat with artificial intelligence – what is it good for?

Many experts say that the development of artificial intelligence can be compared to the invention of the steam engine or electricity. The introduction of AI and its incredibly dynamic development have opened up countless possibilities, not only in various sectors of the economy or the creative industry, but also in everyday situations.

Artificial intelligence is developing at lightning speed. While AI-generated images were a curiosity just two years ago, many people now have trouble telling them apart from real photos. AI can be used to create real voice recordings, songs, films, photographs and even text content that would make the best copywriter proud.

Perhaps the above text fragment was also generated by artificial intelligence?

There are many possible uses for AI – from professional and complex calculations to simple answers to everyday questions. Regardless of the problem, a chat with artificial intelligence can help us solve it.

Examples of basic ways to use AI chats:

  • learning support – explaining issues, organising knowledge and notes, creating effective learning plans;
  • text creation – situations in which artificial intelligence writes an essay on a given topic or helps improve style, punctuation, etc.;
  • learning foreign languages – translation, preparation of exercises, conducting conversations;
  • support in organising the day – planning the week, assigning basic AI tasks;
  • assistance in creative tasks – suggestions for school projects, gift inspirations, etc.;
  • cooking support – creating recipes, developing an individual diet plan, etc.;

Of course, all of the above, as well as more advanced activities, require us to prepare a suitable command. The longer and more context- and detail-rich the prompt, the more satisfactory the answer we will receive.

Which AI is the best and how do they differ? We check!

Many people know what GPT Chat is and associate artificial intelligence with this system. No wonder – its appearance on the web at the end of 2022 caused a stir. Currently, the models owned by OpenAI are used by around 400 million users worldwide.

However, as time went on, more and more solutions competing with GPT began to appear on the web. The biggest tech giants, led by Google, started to develop their own versions. As a result, there are now more than a dozen options available, which differ in terms of access to knowledge, bandwidth, performance, application and special features.

Don’t know which AI chatbot is the best? Want to start using artificial intelligence and wondering which model will best meet your needs? We have prepared a comparison of the three most popular options in Poland for you!

Perplexity vs Chat GPT vs Gemini – let’s see which one is the best!

ChatGPT – artificial intelligence for writing and more!

ChatGPT is an intelligent assistant designed to generate content in a way that is as ‘human’ as possible. It can answer questions, write texts, hold conversations, translate languages and explain complicated things in an easy-to-understand way. It consists of many individual models, such as the universal GPT-4o, o3-mini, o3-mini-high, etc.

Are you looking for a chatbot to brainstorm, plan your day, answer everyday questions or write texts? This artificial intelligence will write any content for you, e.g. an essay or homework, and if you are not satisfied with the results, you can ask it to make corrections.

When it comes to generating longer texts, the AI’s versatility and ‘talkativeness’ are unmatched by OpenAI’s chatbot. It also allows you to generate simple images with DALL-E and analyse attached documents.

ChatGPT advantages:

  • versatility,
  • ability to create long content,
  • simple, conversational use,
  • intuitive and convenient interface,
  • support in everyday situations,
  • multilingualism,
  • personalisation of responses.

However, ChatGPT has its drawbacks. One of them is the so-called ‘hallucinations’, i.e. providing incorrect information. This AI model will not allow a situation in which it is unable to answer your question. For this reason, it is more likely to lie than not to help.

In addition, searching for information on the web may not meet your expectations. The chat uses a research function, but this is limited in the free version. Once this has been used up, the artificial intelligence model from OpenAI will use a knowledge base updated in 2022, rather than the latest data from the web. So you will not receive up-to-date information, e.g. on the US presidential election.

ChatGPT – cons:

  • making up facts (hallucinations),
  • problems with reading emotions,
  • lack of in-depth analysis (e.g. when creating long essays),
  • outdated information during research.

Free version: yes, using older models.

Price for Plus version: $20 / month

Remember that the effectiveness of the answer depends largely on the prompt you provide. The more effort you put into writing it, the better the chance of a satisfactory result.

Perplexity AI – a chat for research with access to the web

What is Perplexity AI? It is a completely different model than the aforementioned chat with artificial intelligence. It differs not only in the way it reasons and formulates answers, but above all in its application. It is used to conduct research, i.e. to search for answers to any questions. It can be compared to an automated and more intelligent Google search engine. Most importantly, it bases its answers on the latest data from the web.

Each answer in Perplexity is confirmed with references to sources, i.e. links. The model converses with us in a dry and factual way – it is not as ‘talkative’ as ChatGPT.

Users of the free version receive answers in a basic form and can also use five more advanced searches per day. Perplexity PRO members receive answers from more than three times as many sources. They can also choose models and change research modes, e.g. focus only on scientific sources, online forums or search for information in R1 mode, which uses advanced reasoning.

Advantages of Perplexity:

  • provides sources,
  • has real-time internet access,
  • less prone to hallucinations.

Cons of Perplexity:

  • limited use (mainly analysis and research),
  • less ‘human’ and creative way of conversation,
  • worse interface than GPT or Gemini,
  • possible inaccurate answers in the free version.

If you are not interested in solving everyday problems, do not need help with creative or intelligent organisation of the day, and are interested in a more advanced internet search engine – Perplexity PRO is an excellent choice!

Free version: yes (fewer sources, 5 PRO searches per day).

Price for PRO version: $20 / month

Gemini – the smart extension of the Google ecosystem

Gemini is a solution from Google, which resembles Chat GPT in its operation and interface. It is based on a conversational model, helps with creative processes and allows for content generation. However, as Internet users point out, Gemini performs worse than the competition from OpenAI in these areas.

This model is an excellent solution if a large part of your daily work is based on the ecosystem of Google. If you purchase access to Gemini Advanced, the premium version, you will be able to easily connect Gmail, Google Docs and Drive to AI. This will significantly improve many processes, such as file analysis or customer conversations.

In addition, we will get access to the Deep Research function, which enables us to carry out very precise research on a given topic and to draw up a comprehensive report based on the data found by the AI. As with GPT Plus, Gemini Advanced allows you to create so-called ‘gems’, i.e. models that are specific to a given activity (e.g. a separate chat for writing texts on social media and a separate one for generating responses for customers).

Advantages of Gemini:

  • supports creative work,
  • integration with the Google ecosystem,
  • Deep Research function for creating large reports (in the paid version).

Disadvantages of Gemini:

  • copywriting is not as good as ChatGPT,
  • possibility of hallucinations,
  • limitations in coding and data analysis.
