AI for beginners: the guide to starting from scratch

What artificial intelligence is

Artificial intelligence is a branch of computer science that develops systems capable of performing tasks that, until recently, were exclusive to humans: understanding text and spoken language, recognizing images, making decisions based on data, or generating original content. It is not science fiction or robots replacing people. It is software that learns patterns from large amounts of data and uses those patterns to respond to new requests.

For most people, contact with AI happens today through conversational tools. You type a question in English, the tool answers in English. No code, no technical language. It is as simple as sending a message.

Types of AI you'll find

There are several types of AI, but as a beginner you will mainly come across these:

To start, focus on conversational tools. They are the most versatile, the easiest to use, and the ones where you can get useful results more quickly.

The best tools to start with

You do not need to try dozens of tools at once. Start with one or two and learn to use them well before exploring more. Here are the most accessible options for beginners:

• ChatGPT (chatgpt.com): made by OpenAI, it is the best known, has a solid free version, and a huge community with tutorials and examples
• Claude (claude.ai): made by Anthropic, it stands out at long-form writing, document analysis, and careful reasoning
• Gemini (gemini.google.com): made by Google, it integrates well with Gmail and Google Docs

All of them have a free version. The difference between the free and the paid version is mainly access to more recent models and higher usage limits. To get started, the free version is more than enough.

How to take the first steps

The best advice for a beginner in AI is to start with a real problem you have today. Do not learn AI in the abstract. Learn by using it for something concrete.

Try one of these tasks in your first session:

• Ask it to help you draft a difficult email you have been putting off for days
• Ask it to explain a concept from your professional field in simple terms
• Paste a long article you need to read and ask for a summary in 5 points
• Ask for ideas for a problem you are trying to solve at work

The key is learning to phrase your requests well. This is called "prompting" and it is a skill that improves quickly with practice. We have an article dedicated to what a prompt is and hundreds of ready-to-use examples in our prompt library.

Common myths about AI

There is a lot of confusion about what AI is and is not. Here are the most common myths worth debunking:

• "AI knows everything": No. Models have a knowledge cutoff and can make mistakes. Always verify critical information.
• "AI is always objective": No. Models learn from human data and can reflect the biases present in that data.
• "I need to be technical to use AI": No. Conversational tools work in natural language. There is no technical barrier to getting started.
• "AI will do everything for me": Not exactly. AI is an amplification tool: it makes you more productive, but you need to know what you are asking for and verify the results.
• "It is expensive": Most tools have a free version that is enough to get started. Paid plans are for heavy users.

Your next step

If you have made it this far, you already have the fundamentals to start using AI in a practical way. The next step is to try it: open ChatGPT or Claude today and solve a real problem. You do not need an elaborate plan. Start small and learn as you use it.

Once you feel comfortable with conversational tools, explore more specialized tools. If you work with code, Claude Code is one of the most powerful tools available today, and we have a complete guide to help you discover it.

The prompt library has hundreds of ready-to-use prompts for the most common situations, a good way to learn what works without having to invent everything from scratch.
