What is it ChatGPT and how does it work?

ChatGPT is an advanced AI chatbot developed by OpenAI, which currently uses the GPT-5 language model to understand and generate natural language. In other words, it is a digital assistant that can write texts, translate, create images, analyze data, search the Internet and much more for you.

And in fact, all with the help of simple text queries, known as prompts.

What are the key features of ChatGPT?

  • Answers questions and writes texts (essays, blogs, emails, ads).

  • Analyzes data from tables and reports.

  • Generates images and explains their elements.

  • Searches the Internet for the latest information.

  • Assists in programming and writing code.

  • It can use voice and recognize images.

ChatGPT currently exists in several versions, but the most famous are:

  • Free version (GPT-4o mini) – limited but sufficient for daily use.

  • ChatGPT Plus (GPT-5) – faster, more accurate and able to use images, voice and files.

  • ChatGPT Enterprise – version for companies, with additional security options.

How to use ChatGPT? Step by step

It only takes a few minutes to get started using ChatGPT.

That process begins as follows:

1. Create an account

Go to chat.openai.com and click Sign up. You can register with a Google or Microsoft account or by using your email address.

In addition to classic typing, you can:

Tips for writing effective prompts

The quality of the answer directly depends on the quality of the query you ask.

That’s why it’s important to learn how to write a good prompt.

Here are two practical examples:

Bad prompt

“Write a text about marketing.”

Better prompt

“Explain what SEO is and how a small business in Belgrade can use site optimization to attract local clients.”

Bad prompt

“Explain SEO.”

Better prompt

“Write a professional text of 500 words about digital marketing for small businesses in Serbia, in pro tone, with examples from practice.”

SmartThink advice:

The more context you provide (target audience, tone, length, goal of the text), the more relevant and useful results ChatGPT will provide.

How to use ChatGPT on phone and computer?

You can use ChatGPT on any device, desktop, laptop, tablet or mobile phone.

On your PC:

Open chat.openai.com

Log in and start a conversation like you would in any chatbot.

You can use the shortcut Alt + Space (Windows) or Option + Space (Mac) to quickly open the ChatGPT window.

On mobile phone:

Download the ChatGPT app from Google Play or the App Store.

Log in and synchronize data with the web version.

Turn on Voice Mode if you want to speak instead of typing.

How to use ChatGPT at work? Practical examples

Artificial intelligence has become an indispensable part of modern business, and ChatGPT is a tool that saves time, increases productivity and brings new ideas.

In the SmartThink team, we use it every day and here are some practical examples to help you understand its real value.

Content writing and blogging with ChatGPT

For marketing teams, ChatGPT is the fastest way to get an idea off the ground. Instead of spending hours devising a title, introduction, and structure, all you have to do is ask a clear question.

Here’s an example from SmartThink’s practice:

When we blog about Google Ads strategies, we use ChatGPT to create a basic outline of the text, then elaborate each part through several prompts, while the final tone and SEO refinement is done by our team.

Result?

A 2,500-word blog that’s keyword-optimized, written in a consistent tone, and ready to post in half a day.

Without him, it would have taken at least one business day to complete.

Advantages:

  • Faster generation of ideas and drafts

  • Unique headlines and CTA suggestions

  • Automatic formatting (H1-H6, lists, bold)

  • Easy to adapt to style and audience

SEO optimization with ChatGPT

ChatGPT does not replace an SEO expert, but it helps and complements it perfectly. It can help with keyword analysis, writing meta tags and creating descriptions that meet SEO rules.

An example from SmartThink practice:

When analyzing client sites, we use ChatGPT to create a WDF-IDF keyword list, suggest phrase variations, and generate optimized meta descriptions for each page.

In this way, we save hours of work on analysis, and we shift the focus to strategy and implementation.

This tool is especially useful for local SEO (eg “catering Belgrade”, “wallpaper Novi Sad”), because it can generate relevant combinations of terms that would otherwise be missed.

ChatGPT vs Gemini or the fight for the throne of artificial intelligence!

In the world of AI assistants, there is a silent but fierce battle going on. ChatGPT and Google Gemini are fighting for the title of the most powerful artificial intelligence tool.

ChatGPT excels in natural language, creative writing, SEO content and data analysis, while Gemini excels in visual tasks, image generation and direct integration with the Google ecosystem.

However, all that we are talking about is subject to strong changes.

If you want a stable and intuitive tool for business, marketing and writing, ChatGPT is still a step ahead for now. But if multimedia processing and connection to Google services are important to you, Gemini takes precedence.

In practice, the best result is a combination of both worlds: ChatGPT for strategy and text, Gemini for visuals and automation.

The AI ​​revolution has begun, and the choice between these two giants depends only on your needs and goals.

ChatGPT in Google Ads and Meta Ads ads

Writing ads that convert becomes much easier with ChatGPT. Just define the goal, audience and text length and it can generate dozens of title and description versions.

Example from SmartThink:

For a client selling luxury plaques, we used ChatGPT to suggest 30 titles of up to 30 characters and 20 descriptions of up to 90 characters.

We then selected the best ones and tested them in a Google Ads campaign.

CTR increased by 22% in the first 15 days.

Advantages:

Generates ads that comply with Google/META rules.

Saves time in the A/B testing phase.

It enables quick adaptation of campaigns to the market.

Data analysis and reports using ChatGPT

At SmartThink, we increasingly use ChatGPT as an analytical tool. It can read Excel spreadsheets, CSV files and text reports and then extract key data.

An example from SmartThink practice:

When analyzing the results of Google Ads campaigns, we feed the report into ChatGPT and request that it display “key metrics with explanation of trends and recommendations”.

The result is an automatically generated summary that gives our worker insight into performance without manual processing. It significantly speeds up the decision-making process and eliminates the possibility of human error.

But you should be careful, because even ChatGPT knows how to make mistakes.

ChatGPT for students, entrepreneurs and freelancers

ChatGPT isn’t just reserved for developers and marketing agencies. It can be an extremely useful tool for any student, entrepreneur and freelancer who wants to increase efficiency and save time.

ChatGPT helps students understand the material more easily, summarize extensive texts, write term papers and graduate papers or prepare presentations without wasting hours of research.

For entrepreneurs, it is like a personal assistant who writes offers, creates product descriptions, plans social media posts and helps communicate with clients.

Freelancers use it for idea generation, content creation, translations, and even writing code or designing prompts for AI images.

In all cases, ChatGPT becomes a tool that saves time, improves the quality of work and allows you to focus on what brings the most value, which is career and business development.

Advantages and limitations of ChatGPT

Like any tool, ChatGPT has its advantages, but also certain limits that should be understood.

We will list, in our opinion, the most important advantages and limitations.

Advantages:

  • Speed ​​and time saving: create quality content in a few minutes.

  • Versatility: can write, analyze, program, design and learn.

  • Affordability: The free version offers enough functionality.

  • Continuity: remembers the context of the conversation and adjusts the tone.

  • Creativity: helps generate ideas, titles and concepts.

Limitations:

  • Does not have access to private data (eg your Google Docs, unless you manually submit them).

  • It can be wrong, so-called. AI hallucinations are still present.

  • He does not always understand the local context (prices, legal regulations, and sometimes even the Serbian language).

  • It is not a substitute for an expert, but an assistant who gives you suggestions.

SmartThink advice:

ChatGPT is most effective when used in conjunction with human supervision. The best results are achieved when AI generates the foundation and a human adds context, style and emotion.

For now, it is, but that is also changing.

  • Always check the facts before posting content.

  • If you use ChatGPT texts publicly, indicate that AI assistance is used.

ChatGPT in the future, what awaits us?

This means that ChatGPT will soon be able to:

  • Automatically writes and publishes articles on your site.

  • It connects to Google Ads and Meta accounts.

  • Creates real-time sales reports.

  • And even communicates with customers for you.

For companies in Serbia, this means the following: it’s time to prepare for the AI ​​revolution in marketing and business.

The SmartThink team is already implementing ChatGPT in working with clients and helping them implement AI-assistants and many other capabilities into their processes.
