Table of Contents

Hey, what's up ;)

If you're here, chances are you:

  • Want to understand what AI is all about but don't know where to start
  • Feel overwhelmed by all the new AI tools popping up everywhere
  • Just want a simple, no-jargon guide to get up to speed

Either way, this guide is for you!

1. AI, simply put

Artificial Intelligence, or AI, is the collective term for computational systems intended to perform tasks that normally require human intelligence.

These tasks can include learning from data, recognizing patterns, making decisions, understanding language, and even creating content like text, images, or music.

On this guide, 'AI' can refer to the technology itself or to tools and apps that use AI behind the scenes.

Disclaimer

This is a complete guide for beginners. Meaning I'm covering everything you need to get started with Artificial Intelligence. My goal here is to give you practical knowledge to start using AI effectively right away. If you spot anything off or incorrect, feel free to let me know!

A brief history of AI

1950s – The Idea Begins

Alan Turing asks, "Can machines think?" In 1956, the term Artificial Intelligence is born at a research workshop. Early AI tries to teach machines to reason using logic and rules.

1960s–70s: Early Hype & Setbacks

AI shows promise in games and math, but struggles with real-world problems. Funding dries up. The first AI winter.

1980s: Expert Systems

Businesses use rule-based expert systems for decisions (e.g., in medicine). But they're hard to maintain, leading to another slowdown.

1990s–2000s: Learning from Data

AI shifts to machine learning, where systems learn patterns from data. In 1997, IBM's Deep Blue beats the chess world champion.

2010s: Deep Learning Boom

Neural networks (especially deep learning) take off, powered by big data and GPUs. AI excels at vision, speech, and games like Go.

2020s: Generative AI

Models like GPT, DALL·E, and Stable Diffusion create text, images, code, and more, just from a prompt. AI becomes creative, useful, and available to everyone.

June-Hao Hou showed on Medium the evolution of images prompted in 2022 vs 2024. Same prompt, different models:

Prompt
Steampunk Animal — an animal with mechanical and steampunk shape in the forest under rays of light.
Apartment Layout — an apartment of 2 bedrooms, large kitchen, living room, with balcony, in French style, facing South, in architectural plan view.
Piano in Forest — grand piano keyboard, closeup view, under forest shades, volumetric light, realistic, depth-of-field.

2. What's the deal with AI?

Yeah, I know. Everyone is talking about AI. Too much noise.

Apart from that, we all know it's here to stay, so one way or another you're gonna have to learn at least the basics.

This mini-guide will provide you an overview, along with a bit of detail, in case you want to dive into it.

So here is my take on how AI is changing everything. And you should be on board.

The Hype

As with any new technology, there's crazy hype around it. Smartphones, Cloud Computing, Crypto, Social Media, you name it.

Every time it's the same: first come the early adopters. The curious ones who love to try new stuff even when it's still buggy or confusing. Then, little by little, regular people start jumping in, usually when the tools get easier or when everyone's talking about it. And before you know it, it's everywhere. Feeds, apps, work, school, until it gets so common that it starts to feel… well, a bit saturated.

All of those trends come in waves, and the moment you catch them can make a big difference. Of course, some of them can totally flop, and you might ask yourself: is it worth the effort? Well, you don't really need to go too deep to actually benefit from it.

What AI is capable to do?

Pretty much, actually.

AI models are built to handle all sorts of tasks. You usually give them text as input, basically an instruction, and they can spit out almost anything digital: text, images, audio, video, or even files.

Some usages AI can help you with:

  • Automating boring or repetitive tasks
  • Summarizing long documents or emails
  • Helping with customer support (chatbots, smart replies)
  • Generating ideas or content (text, images, code)
  • Data insights for decision-making tasks
  • Assisting with language translation or learning
  • Boosting productivity with smart tools (like scheduling or reminders)

Do I need to know how to code?

Short answer: it depends.

Do you want to actually build something? So, it would be nice to learn a thing or two.

Although there are lots of no-code tools, at some point you need to make it available to your customers, so you may have to pay someone (or some service like fal.ai) to take care of it for you, or you may have to do it by yourself.

On the other hand, if your idea is to use AI tools in your day-to-day tasks, you can benefit from AI-powered SaaS, since they hide all of the complexity. Those can deliver a very friendly experience without needing any previous experience in tech.

Regardless, knowing how to use AI can make all the difference here. Nowadays it is almost mandatory for people to know at least some concepts, along with the benefits of what AI is capable of providing.

3. Key concepts

What we refer here as AI is basically the ability to transform any sort of input into some useful output. Take these text-to-image tasks, for example, prompted to ChatGPT.

In this case the input is text and the output is an image. It could be text-to-video. Or image-to-image. Maybe image-to-video. Text-to-audio. The AI tool just takes an input, processes it and returns an output.

It's very common also expressions like 'training a model' or 'prompt engineering'. A whole set of jargons were created to refer to AI concepts. Next you can have a look at some of the most fundamental concepts.

Prompts

Think about prompts as instructions.

You want to tell the model to perform some task, or to generate something, then you write instructions containing your goal and the way the output is supposed to look in human-readable text.

The better and more precise the instruction, the better and more predictable the result.

For example, take this pasta recipe:

Make pasta with sauce.

Boil stuff, mix, and serve.

The result would be totally unpredictable — the cook has to fill the gaps and assume measures and time. Which kind of pasta? How much? How long should it be in the oven?

Now, check out this version of the same recipe:

Ingredients

  • 200g of Penne pasta
  • 200g of Tomato sauce
  • Olive oil, Salt, Garlic, Parmesan cheese

Instructions

  • Boil 200g of penne pasta in salted water for 10 minutes until al dente.
  • In a separate pan, heat 2 tablespoons of olive oil, add 1 minced garlic clove, and cook for 1 minute.
  • Add 200ml of tomato sauce, a pinch of salt, and simmer for 5 minutes.
  • Mix the drained pasta with the sauce, sprinkle with grated parmesan, and serve hot.

If you follow both recipes, which one has more chances of success?

The idea is the same with prompts. We want to express your needs and give instructions in the clearest way possible.

Advanced Prompting

Once you master basic prompting, you can chain multiple prompts together for complex tasks:

  1. Break big tasks into steps – Instead of "Write a business plan," try "First, analyze my target market. Then suggest 3 business models. Finally, outline a marketing strategy."
  2. Use outputs as inputs – Take the result from one prompt and feed it into the next for refinement.
  3. Iterate and improve – Ask "Make this more specific" or "Add more examples" to polish results.

This technique helps you get better results from any AI tool.

How to build effective prompts?

Think of prompting like giving instructions to a smart but literal intern. The clearer you are, the better results you get.

The 4-Part Prompt Formula:

  1. Context – Who are you? What's the situation?
  2. Task – What exactly do you want?
  3. Format – How should the output look?
  4. Examples – Show what good looks like

Bad Prompt: "Write an email"

Good Prompt: "I'm a small business owner. Write a follow-up email to a potential client who viewed our proposal last week but hasn't responded. Keep it friendly but professional, under 100 words. Include a gentle reminder about our 15% early-bird discount that expires Friday."

Pro Tips:

  • Be specific about length, tone, and style
  • Give examples when possible
  • Ask for multiple options: "Give me 3 different versions"
  • Iterate: "Make it more casual" or "Add more technical details"

For advanced techniques, check out Anthropic's prompting guide or Google's prompt engineering whitepaper.

Models

An AI model is the "brain" that makes everything work. Think of models like different specialists — some excel at writing, others at creating images or understanding speech.

When you use ChatGPT, you're talking to a language model trained on billions of text examples. When you use DALL-E, you're using an image model trained on millions of pictures and descriptions.

Popular models you should know:

  • GPT / ChatGPT – Best for conversations, writing, analysis
  • Claude – Great for detailed explanations and reasoning
  • DALL-E – Creates images from text descriptions
  • Midjourney – Artistic image generation
  • Stable Diffusion – Open-source image creation

You don't need to understand how they work — just know that different models are better at different tasks.

Where should I start?

Getting started with AI is easier than you think. Here's your step-by-step path:

Week 1: Text AI

  1. Go to ChatGPT and create a free account
  2. Try these starter prompts:
    • "Explain [any topic] like I'm 5 years old"
    • "Write a professional email about [your situation]"
    • "Give me 5 ideas for [your project/problem]"
  3. Spend 15 minutes daily just experimenting

Week 2: Image AI

  1. Try DALL-E (built into ChatGPT)
  2. Start with simple prompts: "A cat wearing a business suit"
  3. Learn to be more specific: "A professional headshot of a confident woman in a navy blue blazer, clean white background, corporate photography style"

Week 3: Explore More

Golden Rule: Start simple, experiment daily, don't worry about being perfect.

Training

Training is the activity of adding more context to a model.

When people say an AI model is "trained," they're talking about how it learned everything it knows.

In simple terms, training is the process of showing the model massive amounts of data (like books, images, videos, music, code, etc.) so it can learn the patterns and relationships between things.

Low-Rank Adaptation (LoRA)

LoRA is a clever way to customize big AI models without retraining them from scratch.

Let's say you have a huge, powerful model (like GPT or Stable Diffusion). Training it again just to specialize in, say, writing like Shakespeare or drawing in your favorite art style would take tons of time, data, and money.

That's where LoRA comes in.

4. Text & LLM: anyone can be a writer

Let's talk about the AI behind most of the tools you see creating text.

LLM stands for Large Language Model. It's a type of AI trained on a lot of text — like, the entire internet kind of "a lot" — to learn how language works.

What can it do?

  • Write essays, blog posts, emails, poems, jokes (some even funny)
  • Summarize long stuff into short stuff
  • Translate between languages
  • Answer questions like a nerdy but helpful friend

If you've used ChatGPT, Claude, or even Google's Gemini, you've met an LLM. They're like autocomplete on steroids, but way smarter.

Run your own LLM locally: Ollama lets you run open-source models on your own machine.

5. Image: who needs a camera anyway?

Ever seen AI create pictures from just a few words? Welcome to the world of generative image models!

You can type something like: "A penguin skateboarding through Times Square at sunset"

…and AI will give you an image of it. (Yes, even the penguin part 🐧🛹)

You can even specify which camera you want, the lens, the style of shot in your prompt.

Example prompts to try:

Name Prompt
Steampunk Animal an animal with mechanical and steampunk shape in the forest under rays of light
Apartment Layout an apartment of 2 bedrooms, large kitchen, living room, with balcony, in French style, facing South, in architectural plan view
Piano in Forest grand piano keyboard, closeup view, under forest shades, volumetric light, realistic, depth-of-field

Tools like FLUX, Midjourney, DALL·E, and Stable Diffusion make this possible.

Some use it for fun, others for design, marketing, or to visualize ideas without hiring an illustrator. It's not perfect, but it's pretty amazing — and it's getting better really fast.

6. Audio: make music like a pro

Now imagine giving AI your voice, and it speaks anything you want it to say. Scary? Cool? Both? Yeah.

AI in audio is doing things like:

  • Voice cloning
  • Music generation
  • Speech-to-text (like transcribing a meeting)
  • Text-to-speech (making your text talk with different voices)

You might have heard tools like ElevenLabs, Descript, or Voicemod. Whether you're making a podcast, creating content, or pranking your friends — AI's got a voice for that.

Recommended tools:

  • Udio – AI music generation
  • Suno – Create full songs from text
  • ElevenLabs – Voice cloning and TTS
  • MMAudio – Audio generation models

Open-source models:

7. Video: filmmakers, watch out

AI can now help you create videos without filming anything.

Let that sink in.

There are tools that let you:

  • Create a presenter that looks human but is 100% AI
  • Animate images or text to make explainer videos
  • Edit videos automatically (remove pauses, "ums", even change your mouth to match new audio)

From tools like Runway, Pika, to Synthesia, video is becoming one of the most exciting AI playgrounds out there. We're not far from typing a script and letting AI do the rest.

Recommended tools:

8. Agents: should we be worried about our jobs?

This one's cool — and a bit sci-fi.

AI agents are like little digital assistants that can take actions for you. They don't just respond — they do things.

Imagine asking an agent to:

  • Find the best flights, book them, and email you the ticket
  • Chat with customers on your website
  • Use software on your behalf (like filling out spreadsheets or sending reports)

They're powered by LLMs + automation tools, and we're still early — but things like AutoGPT, AgentGPT, and Open Interpreter are already giving us a glimpse of what's coming.

Recommended tools:

  • n8n – Visual workflow automation with AI
  • LangChain – Framework for building AI agents
  • Relevance AI – No-code AI agent builder

9. Coding: so you're a dev now! how's that feel?

AI coding tools are basically your new best colleague — one that doesn't sleep and writes code way faster than you (sorry).

They can:

  • Suggest code as you type
  • Explain what some spaghetti code does
  • Help debug errors
  • Generate whole functions or even apps from scratch

You don't need to be a dev to build cool things anymore. AI is lowering the bar to entry — and that's kinda beautiful.

Recommended tools:

10. MCP: Multi-Modal Composition Pipelines

MCPs are setups or workflows where multiple AI models work together to generate something more powerful or complex than a single model can do alone.

Think of it like a chain of tools, each doing its part — one generates text, another turns it into an image, another adds animation, etc.
