Personal experience with AI models and ChatGPT

WITH ChatGPT and AI the bag was torn. Several times a week I deal with how someone implements AI, wants it or at least talks about it. Maybe on Google Keynote in May, the word AI was used approx. 140 times in two hours. You can listen to how it sounded here.

When the first publicly available AI models appeared last fall, it was quite a shock. But AI in some form has been with us for a long time. It is used, for example, in your Google services (try searching for the word dog on Google Drive, it will also find dogs in pictures) or Apple devices (automatic generation of videos and collages). But ChatGPT brought a revolution. You can find an interesting interview with Sam Altman from OpenAI (maker of ChatGPT) about how they see it here.

What about Google? It also has an AI model. His name is Bard, he is here and is also available in Czech from 13.7. 2023. Until then, it was banned in the EU due to data protection and was only available via VPN. Great name for me!

The state of AI awareness among users

Many people are interested in AI tools, ask about them and often have distorted ideas. Distorted ideas, for example, that it is a technology that will be available in a few years. It is not so. To prove it, I implemented a chatbot based on ChatGPT 3.5 Turbo technology on my blog. It took me about 30 minutes. That I'm on my own and it's not possible in a corporation? You will say it in Spořka. The same chatbot has been implemented since March 2023. And other companies are joining. For example Slovak Savings Bank.

But the real fun will come with the arrival of Copilot from Microsoft. You just get a new feature in Office one day. When? This of course depends on your license. But it will be sometime in the next year or so. Certainly not in a few years. Suddenly, rank-and-file employees will have access to all options. Are they ready for it? And you? 🙂 How to use ChatGPT and AI tools can be found in the article here.

Microsoft 365 Copilot is a disguised chatGPT in the Office 365 package (Microsoft 365):

How could it be used? Try samples for specific Office tools:

The AI tool / ChatGPT is already available to you. Maybe you don't even know about it. You can go straight here (registration is required) or you have it in the Edge browser on your computer. Look for the blue icon - it will be at the top right of the EDGE browser.

What am I trying to say with all this? The future of work is here!

ChatFast tool on my blog

Why did I deploy an AI / ChatGPT chatbot? Because hands-on experience is the best. And because I deal with the topic of using AI several times a week. Basically, any training or consultation regarding technology always turns to the topic of AI and chatGPT at least for a moment. Yes, I also heard that AI will take people's jobs or destroy the world. Maybe it will happen, I don't know. But I'd rather be prepared for it, understand it, and be in active mode than to wait with folded hands to see what happens.

ChatFast is an available platform that I used for experiments. It allows you to create a GPT chatbot from your own data. The chatbot answers users' arbitrary questions and you only need to insert it into the page where you need it. Custom data means either some text you give it (PDF, Docx, etc. files) or you link it to some online resource (like a blog). The chatbot goes through the data, studies it, and then generates answers to people from it. When he gets a question that isn't included in the data (you ask for a tenderloin recipe, but the blog is about digital balance), he doesn't know. Similar to a human. If you ask me what he is like the difference between highlands and mountains, so I won't know either.

But unlike me, the chatbot understands more than 50 different languages. When you ask a question, it will do its best to answer you in the language you asked, even if the source text is written in another language.

ChatFast can also train the chatbot using different data sources and add custom questions and answers to help the chatbot answer specific questions. In addition, the chatbot can collect information about visitors (name, email, phone number) and provide information about why visitors contact you. This can provide valuable analytical data.

First impressions

In one word, great! I never thought that how people will use a chatbot. I expected sophisticated questions and probing. Instead, they try to troll him a lot or ask stupid questions. And it must be said that he can handle it very well. How do I know? All conversations are saved and I can go through them. It's a fun count!

Example of a chatbot conversation with a website visitor:


How I did it and how FastChat works

A picture is worth a thousand words, but here's how it works. The blog visitor can browse and read individual articles or the chatbot can answer specific questions. The chatbot has access to blog content from which it learns answers and then gives them to the user. The advantage is that you can ask the chatbot questions in human language, i.e. Why should I turn off notifications? or How to get started with digital balance. You don't have to look for the answers in the articles yourself. The chatbot will respond and add a link to the article where it found the information. It's a much more accurate and pleasant interaction. If the chatbot doesn't know, it will write it.


You can simply ask what interests you. This is the main difference against the classic query on www.google.com. You can't ask Google like a human, but you have to give it so-called questions. He takes the query, searches the internet and returns the result to you.

In contrast, the AI model learns the content you give it (for example, the entire Internet) and you can ask it like a human. He "understands" (he doesn't really understand, please take the expression with a grain of salt) what you are asking and he will answer you. You don't need to browse content (articles) on the internet. AI is like a colleague that you can ask anything at any time. And he always knows the answer (almost always and sometimes he can make it up).


Everything is paid for and everything has a price. ChatFast and the use of AI tools is no exception.

The most obvious price is the one one has to pay. I have the paid version of ChatFast Basic for $29 for a month. Of course, you can also start with the free version, but 100,000 characters was not enough for me. It is the number of characters in the data source, in my case, the blog. Maybe you have the characters counted, I didn't 🙂 But ChatFast will count them before connecting and tell you. I was quite surprised that even I got over a million characters relatively easily. And I also care about the principle - things are paid for by default. Let alone for things that have access to your data.

This brings me to the second point – ChatFast has access to the entire content mine blog. Everything I've ever created cost me time, energy and money, so I gave it to him on a golden platter. It's "relatively" cool with a publicly available blog, but not so cool with any internal, personal or non-public data and you need to think about it.

Also of course you need some content, which you feed the AI. It can only answer questions for which it can find answers in the source data. If it has little input data, its added value will also be small. To give you an example, my blog is about the relationship with technology. If you ask the chatbot, for example, about football - who is the best club in the Czech Republic, it will not know. I don't blog about it.

In general, AI also has a little difficulty with so-called fact checking. In practice, this means that can and enough piffle. It's good to think about it and check any facts.

And finally, people don't know how to use these tools. This is of course understandable. The technology is new and not everyone is a geek who thinks about a digital footprint. There is a simple rule: What you upload to the Internet can no longer be deleted. That should be enough for you. Just don't use specific or internal information when using AI tools. What you wouldn't say to a stranger at a bus stop doesn't even belong in an AI chatbot. Otherwise you will end up like v Samsung or Apple, where they preferred to ban these technologies for employees. Instead of I work at XYZ company, use I work at a Czech bank. It's like this: I have one friend….
