AI for everyone: how to use artificial intelligence for free and get more done

Every week I get the same question: "Uriel, how do I get started with this AI thing?"

The short answer: you already have access. Probably for free. And you can start today.

This article is for everyone — it doesn't matter if you're a student, entrepreneur, accountant, designer, or just someone curious. You don't need to know how to code. You don't need to pay anything to get started.

First: what is AI, really?

Forget the movies about robots. In practical everyday terms, artificial intelligence today is mainly one thing: language models (LLMs) that can read text, understand it, and respond coherently.

Think of it as an incredibly well-read assistant that:

Has processed millions of books, articles, and documents
Can explain any topic simply
Can help you write, summarize, translate, and correct
Responds in seconds, in your language, at 3am if you want

The free tools you should try

1. ChatGPT (OpenAI)

→ chat.openai.com

The most well-known. The free version (GPT-4o) is sufficient for most everyday tasks. You can ask questions, request explanations of concepts, have it correct your writing, or help you organize ideas.

Use it for: learning something new, drafting emails, summarizing documents, preparing for interviews.

2. Claude (Anthropic)

→ claude.ai

My personal favorite for tasks that require deep analysis and long responses. It's especially good at reasoning step by step and being honest when it doesn't know something.

Use it for: analyzing documents, writing long-form content, thinking through complex problems, learning to code.

3. Gemini (Google)

→ gemini.google.com

Integrated with Google services. If you use Gmail, Drive, or Docs, Gemini can help you directly within those tools.

Use it for: finding up-to-date information, working with Google documents, quick queries.

4. Perplexity

→ perplexity.ai

An AI-powered search engine that cites its sources. Ideal when you need current information and want to know where it comes from.

Use it for: researching topics, fact-checking, replacing Google searches for complex questions.

10 concrete ways to use AI starting tomorrow

These aren't abstract ideas. These are things I and my team do weekly:

For studying

"Explain [difficult topic] like I'm 15 years old" — LLMs are excellent, patient teachers
Exam prep: ask it to create practice questions on any topic
Translate and explain: paste an article in another language and ask for a summary

For work

Draft professional emails: describe the situation, ask for the email, adjust to your voice
Summarize meetings: paste your notes and ask for key points and action items
Correct and improve text: paste what you wrote and ask it to make it clearer

For entrepreneurship

Validate an idea: ask it to play devil's advocate and tell you what could go wrong
Generate content ideas: "give me 20 post ideas for a bakery"
Create product descriptions: much better than starting from scratch

For learning something new

Personalized learning plan: "I want to learn graphic design in 3 months, I have 1 hour a day, where do I start?"

The myths holding people back

"It's hard to use" It's not. If you can type a WhatsApp message, you can use AI. The interface is exactly that: a chat.

"It's only for programmers" Completely false. In my experience, the people who benefit most are those who don't code: teachers, entrepreneurs, office workers, students.

"It's going to replace my job" Current AI replaces tasks, not people. Someone who uses AI will replace someone who doesn't. The difference is made by whoever asks better questions.

"It's expensive" The free tiers of ChatGPT, Claude, and Gemini are sufficient for 90% of everyday use cases. Paid versions (~$20/month) are for power users.

How to use it better: the prompt is everything

The quality of what you get depends directly on how you ask. This is called prompt engineering and you don't need a course to learn it.

Three simple rules:

1. Be specific

❌ "Help me with my resume"
✅ "I'm an accountant with 5 years of experience looking for a job at a 
    mid-size company. Review this resume and suggest how to improve the 
    executive summary to highlight my achievements with concrete numbers."

2. Give context and a role

✅ "Act as a high school physics teacher.
    Explain Newton's second law with a real-life example."

3. Iterate If the first response isn't perfect, don't start over. Ask for adjustments: "Make it shorter," "Use a more formal tone," "Add examples."

What's coming: AI in Central America, unfiltered

I'm working on something that has me very excited: a community and content channel focused on demystifying and democratizing artificial intelligence in Guatemala and Central America.

The goal is simple: help more people — regardless of their technical level — use these tools to improve their lives, work, and businesses.

If you're interested in being part of it or staying informed when we launch, write to me directly. This is just the beginning.

To close

Artificial intelligence is no longer the future. It's the present. And the good news is that the barrier to entry is almost zero.

All you need to start: curiosity and 10 minutes.

Open ChatGPT or Claude, type something you'd normally Google, and see what happens. You'll be surprised.
