what it is, how to use it and everything you need to know about this Internet-connected AI search engine

Faced with ChatGPT, there are those who have the same feeling as when they tried the internet for the first time, but the reality is that despite its great potential, OpenAI’s conversational chat has flaws and limitations, one of which is the lack of sources or that it does not connect to Internet to search for answers. But ChatGPT is not alone: ​​there are AI tools capable of looking face to face at OpenAI chat like Perplexity AI. If you are not sure what Perplexity AI is, what it can be useful for and how to starta good start can be reading this article.

What is Perplexity AI?

Perplexity AI is a conversational search engine, that is, an answer engine that provides precise answers to more or less complex questions using extensive language models. Thus, its accuracy is limited by the capabilities of artificial intelligence and search results.

As its creators warn, as a result it can generate offensive or dangerous content. Also, recommend not to provide personal informationgiven that like other AI algorithms, it is train with the use. That is, with your questions, their answers, feedback and analysis by the development team.

What difference then ChatGPT with Perplexity AI? If you’re just starting to try out these AI tools, you may have made a hodgepodge of what’s good for what and what to expect. We start with something as important as the internet connection: while ChatGPT is “limited” to its training and data (note, more than 175 million parameters, which are not few), Perplexity AI relies on the immensity of the internet to offer you answers , which allows you keep up to date with what is happening and search if needed to offer answers in real time.

The second big difference has to do with the sources and it is essential: What good is it that ChatGPT offers you an answer that seems true to reality if you can’t verify it unless you have a lot of experience in the subject? This is one of the reasons why it is so dangerous to use it for class work or even for programming, which is why its use is prohibited to solve Stack Overflow doubts. After you provide your answer, Perplexity AI lists where it got the information from, so you can check it yourself.

In any case, both ChatGPT and Perplexity AI stand out for their ability to contextualizewhich allows to maintain a conversation in the case of OpenAI chat or to chain a interrogation with Perplexity AI. For example, if you ask him about the latest Apple phone and then ask him “and the laptop?”, he is able to understand that we mean the Apple computer.

If we compare it with Google, the difference is abysmal: while the Mountain View engine is essentially limited to returning results in SEO order (although it increasingly places more importance on their suggestions and less on pure linking), Perplexity AI understands your question, looks for the answer and is able to write it, not as a copy-and-paste, but taking the sources that he considers most relevant and constructing a discourse with meaning and precision. For us to understand each other, it’s like doing a job old fashioned: document yourself, to understand and elaborate the answer using different concepts. At the end of the answer, your sources as a bibliography.

Regarding functionality, roughly Perplexity AI would be a kind of hypothetical child between ChatGPT and Google.

How to use Perplexity AI?

After explaining its capabilities and operation, it is normal that you want to try it. Well, you can do it: although still in beta phase, It’s open to everyone and it’s free.. In addition, it is a good time to do it: it does not have traffic problems and its operation is fluid.

An interesting point is that you don’t even need to registerSimply access their website from any browser (it can be on a computer, tablet, mobile) and enter your question. The interface is very similar to that of the Google search engine.


As you may have seen in the Perplexity AI screenshots that we have posted to illustrate the article, the menus and texts on the website are in English, but you can ask questions in Spanish and he will also answer you in Spanish.

A couple of interesting tidbits: When switching languages, you tend to opt for local fonts. We have also tested it in French and Basque and in both cases it is able to understand the question and answer it, but while in Spanish and French it returned the question in those same languages, in Basque it chose to answer either in English or in the language that we had formulated the previous question.

Ideas for using Perplexity AI

Now that we are clear about what it is and how to use Perplexity AI, we may need ideas to put it into practice. Taking advantage of its status as an updated search engine, let’s go with a rabidly topical question: who is behind Netflix? Note: let’s remember that Reed Hastings has ceased to be CEO of Netflix a few hours ago.

Netflix CEO

As you can see, Perplexity AI is already aware of the current situation. So you can be useful to offer a summary of the newsavoiding several clicks, readings and headlines clickbait. The sources offer little objection: Netflix itself, Wikipedia and two reputable outlets such as CNBC and the Hollywood Reporter. In case of doubt of its veracity? You can always compare by pulling sources.

Thus, it is assumed that it will be fully up to date with competitions and statisticsFor example, which player has scored the most headed goals so far in the first league. But this was an easy statistic.

If we ask him about the Chilean ones, he has no answer, since he is not able to find a source that offers him the data. However, regarding which player has scored more with his left leg, yes.

Screenshot 2023 01 23 At 8 27 28

only one source, Marca and its player statistics database, which means that it has not been able to cross this data with other information to compare it. And if Brand is not updated? So the answer will be wrong.


Keep up to date with what is happening can be useful for issues that change frequently, such as knowing what will be the price of electricity in Spain tomorrowthus, without having to specify the day.


As data, the price of electricity for tomorrow is provided by the Red Eléctrica de España (REE) the day before, so in practice yet (it is 8 am) it is not possible to know the concrete answer. In the concise answer Perplexity does not get wet, but in the detailed one it does give us some indications to know it and the sources to verify it. The reliability of the answers is not entirely accurate.

Or something that doesn’t change that frequently, for example novelties implemented in legislation or regulations. Another example: suppose the battery of my iPhone 13 Pro has deteriorated and I want to replace it in the Apple SAT, which has official prices. The problem? That these change from February 28. Will Perplexity know?

Not only does he know this variation, but he also gives you advice so you can save some money by changing it to a different SAT that is listed as a source. It’s not the only one, but what good publicity.

This can be useful for long-standing processes with numerous changes, for example the emergency lights for V-16 vehicles. It must be taken into account that although initially there was talk of some requirements, at the beginning of last year there was a reform in the Roadside Assistance Regulations adding the need for it to be connected and with geopositioning.


Be careful here because while in the extended version it does explain it, in the concise version it can lead us to error. It is not infallible.

As you can see, although the understanding of the question and the context is correct and the connection allows you to be quite up to date with the news, the reliability of the answers is subject to the number of sources with that data, their credibility and the comparison of data.

If your screen goes black in Windows 10 and 11, this command will save you from rebooting

Operating systems aren’t perfect, and Windows is no exception. Day by day many errors are reported, such as the inability to boot the computer with Windows 11 and also sometimes it can happen that the desktop suddenly appears black rendering the computer unusable.

This fact is characterized by the disappearance of all the icons on the desktop and the taskbar. This is because ‘Explorer’ process stops suddenly due to unexpected problem without generating any visual error. But there are ways to reverse it in a very simple way, although at first it seems that nothing can be done with the computer.


A simple command that can save your computer

Although the Windows interface seems to have disappeared, the truth is that you will be able to continue using your computer. To do this you simply have to press the keys Control + Shift + Escape. The task manager will automatically open where all the processes that are running as well as the main programs that are active at that moment will be displayed.

What is interesting in this window is to press Run new task. You will see that a dialog box opens where you can enter a text next to the word “Open”. Specifically, you will have to write “Explorer.exe” and then click on Accept. At the moment, Windows Explorer should be run again and therefore the taskbar and icons will appear on the desktop. This window can also be opened pressing Windows + R.

It should be noted that this trick will only work when everything is black but if the mouse appears. In the event that nothing is visible, it is likely that the error resides in a hardware component such as the graphics card or RAM memory, and it can even be a bug in the operating system. In these cases, it is recommended to restart the device.

How to fix problems or failures when installing updates in Windows 11

Another solution that can be considered if the taskbar works is to enter Start and search for the term REGEDIT, clicking on the first option found. Among all the folders that appear, follow the path HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionWinlogon. Finally, in the list of elements on the right, you will have to click on Shell and write the word explorer.exe. From here the process will be loaded as in the previous case.

A section that is given special interest in this European website is equality, with programs that give visibility to the challenges that women constantly face due to gender or sex issues, such as testimonies from women about the fear of returning home alone, about the rapes they have suffered or about abortion. There are also programs on the situation of women in other parts of the world such as Iran.

The war in *text muted*, which is now one year old, also has special attentionas well as the rights of LGTBIQ people+. There is an exclusive section on politics and society and another on psychology.

The entire Spanish Film Library, free on the Internet: this is the "Netflix" preparing


As for movies you have, above all, short films, with titles like ‘The black bear’, ‘Wild love’, ‘Bad Bunny’ or “He, who has two souls”. There is also ‘Grandma’s Sex Life’, which holds the title of Best European Short Film 2022 about the intimate memories of an older woman that illustrates the condition of Slovenian women at the beginning of the s. xx.

There is another section of European series like ‘Loulou’, ‘Metro Veinte’ or the Ukrainian ‘Mama’. You also have dozens of cultural documentaries.

What is ArteKino Classics

Akc Lastradalogos

This is a project financed from the European Union. ArteKino Classics, which is now launching its second edition, was born almost a year ago under the premise that “the Europe’s film heritage it is a cultural treasure of astonishing diversity” and it is hoped that many works can reach all the citizens of the continent.

This brings together both well-known classics and movies who are remarkable for their vision of the worldtheir cinematography or their performances.

The Youth Cultural Voucher of 400 euros can now be requested without a digital certificate: we tell you how to do it at Correos

Among what you can already find on you have: about 56% of the programming are documentaries; 19%, motion pictures and fiction; 14%, informative programs; and 5%, music and live shows. Two thirds of the channel’s programs are unpublished.

ART negotiates the rights of all these programs to be able to present to users outside of France and Germany an increasingly abundant offer. If, for some reason, ARTE does not have the international rights for the video you are about to watch, the following message will appear: “This video is not available in your country.”

This nun created the BASIC language (and became the first PhD in computing) 24 years after entering the convent

Although few people know it, June 7, 1965 was a very important day in the history of computing: that day the first two doctoral degrees in Computer Science were awarded of history (not that there weren’t experts in the field before that, of course). The first, by the University of Washington, went to Irving C. Tang, while—just a few hours later, at the University of Wisconsin—the second went to a woman: Sister Mary Kenneth Keller.

Keller, born into an Irish-Catholic family, had entered in 1932 (with 19 years) in the congregation of Sisters of Charity of the Blessed Virgin Mary in Dubuque, Iowa. After 8 years as a novice, she took her vows in 1940 and began teaching mathematics in congregational schools.

And after that, he began his academic career in the academic field, earning a degree in Mathematics in 1943 (which allowed him to start teaching secondary school students) and a master’s degree in Mathematics and Physics in 1945.

Thus, when his religious order founded Clarke University in 1964, it became the first small university to offer a computer science degree in the US. At the head of said title, as director of the Department of Technology was, of course, our protagonist. She would be her director for two decades, until a few months before her death in 1985.

It was a few months after her appointment as director when, having already turned 52, she was awarded her doctorate by his thesis “Inductive Inference on Computer Generated Patterns”focused on the development of algorithms capable of performing an analytical differentiation on the algebraic expression.

For some strange reason, Barbara Liskov (creator of the CLU and Argos languages) is often cited as the first female PhD in computing, despite receiving her degree three years after Sister Keller.

Staunch defender of the accessibility of computing to non-specialized users

The programming language that she used in the algorithms proposed in her thesis was the -even today- famous FORTRAN… despite the fact that a year before she herself had become one of the three creators of another language called to be even more popular than that one : the “Beginners’ All-purpose Symbolic Instruction Code”, better known as BASIC.

In 1958, Dartmouth College had decided breaking her ‘male only’ rule (current for 188 years) to allow Keller in as a researcher for its Computer Center, where she began collaborating with John George Kemeny and Thomas Eugene Kurtz. From this collaboration arose the original dialect of BASIC (known as Dartmouth BASIC), of which her male colleagues are often cited as the sole creators.

What moved Kemeny, Kurtz, and Keller to consider creating BASIC was the need to allow students to write programs on time-sharing systems, systems that for the first time were open to users outside the computing area itselfwho needed power relatively easy to programalthough that would sacrifice some of the performance of the program.

Basic Programming Manual in 1984

Sister Keller was one of the earliest and most enthusiastic advocates of apply computing to the teaching of all areas of knowledge (an idea fully accepted today, but controversial at the time), which involved guaranteeing its accessibility at a time when it was still enormously expensive:

“We are experiencing an information explosion, and it is obvious that information will not be useful unless it is accessible.”

“For the first time we can now mechanically simulate the cognitive process. We can carry out studies on artificial intelligence. Furthermore, the computer can be used to help humans learn.”

“In the future, the number of those who will study this subject will increase, and as a consequence, the importance of teachers will also increase.”

As a consequence of this conviction, it was also co-founder in 1967 of the ASCUE (Association Supporting Computer Users in Education), promoting the use of computers in education. And, of course, she publicly endorsed, both by word of mouth and by his example, the presence of women in computer science.

Keller also performed a very current prediction in these times marked by the prominence of ChatGPT and other artificial intelligences:

“For the first time, we can simulate the cognitive process in a mechanical way. We can do studies on artificial intelligence. Beyond this, this mechanism (the PC) can be used to help humans learn. Over time we will have more students and more mature, so it is likely that this type of teaching will gain importance.
