How to Use AI: A Complete Beginner-to-Advanced Guide
Learning to use AI well comes down to four things: understanding what these tools actually are, learning to prompt them effectively, knowing which tool fits which job, and practicing on real tasks instead of toy examples. This guide covers all four, in order, and links to the actual courses — 50 of them, free on any AIVX Labs plan — that go deeper on each one.
Key takeaways
- AI tools (ChatGPT, Claude, Gemini, Perplexity) are language models trained to predict and generate text — they don't "know" things the way a search engine indexes pages; they generate a response based on patterns in their training.
- The single highest-leverage skill is prompt specificity: a vague prompt gets a generic answer; a specific one with context, format, and constraints gets a usable one.
- Different tools have different strengths — there is no single "best AI," only a best fit for a given task.
- The fastest way to get good is to use AI on your own real work, not generic tutorials.
What AI actually is (in plain terms)
The tools most people mean when they say “AI” today — ChatGPT, Claude, Gemini, Perplexity — are large language models (LLMs). An LLM is trained on enormous amounts of text and learns to predict what text should come next, given what came before. Ask it a question, and it generates a response one piece at a time based on patterns it learned during training — it's not looking anything up in a database unless it's specifically using a search or browsing feature.
That matters practically: an LLM can produce a confident, fluent, wrong answer (often called a “hallucination”), especially on obscure facts, dates, or citations. It's extremely strong at language tasks — writing, rewriting, summarizing, explaining, brainstorming, structuring — and at reasoning through a problem step by step when asked to. Treat it like a very fast, very well-read collaborator who needs clear direction and whose specific factual claims are worth double-checking, not an oracle.
Getting started: your first week
Skip the tutorials that just show you the chat interface — you already know how to type into a box. The actual skill is in what you type. In your first week:
- Pick one real task you do regularly (a weekly email, a report, a social post) and use AI for it every time instead of doing it from scratch.
- Give it context it would need if it were a new hire: who this is for, what tone, what it's based on, what to avoid.
- When the output is off, don't start over — tell it exactly what's wrong (“too formal,” “cut this to 200 words,” “add a specific example”) and ask it to revise.
- Notice which instructions consistently get you a usable first draft — that's the beginning of your own prompting style.
Learning to prompt well
A prompt is more useful the more it looks like a real brief, not a search query. The difference between a vague prompt and a specific one is the single biggest factor in output quality:
Vague
“Write me an email about our new product.”
Specific
“Write a 150-word email to existing customers announcing our new [product], in a friendly but not salesy tone, with one clear call to action to book a demo. Here's our last announcement email as a style reference: [paste].”
For a full breakdown of specific techniques — role prompting, chain-of-thought, few-shot examples — see What Is Prompt Engineering? or the real courses Prompt Engineering 101 and Prompt Engineering Advanced, both included free.
Which AI tool should you use?
There's no single best AI — each has a different design emphasis:
- ChatGPT (OpenAI) — broad general-purpose use, a large plugin/GPT ecosystem, strong multimodal (voice, image) features.
- Claude (Anthropic) — long-context reasoning, careful and structured writing, widely used for coding assistance.
- Gemini (Google) — tight integration with Google's own products and search/knowledge features.
- Perplexity — built specifically for research, with inline citations to its sources rather than a plain generated answer.

If you're just starting
Focus on one tool, one real recurring task, and the describe-review-refine loop above. Resist the urge to learn every tool at once — depth on one beats breadth on five for the first month.
If you're already comfortable
Move from one-off prompts to repeatable workflows — chaining several AI steps together, using system prompts/custom instructions, and exploring AI agents for tasks that need multiple steps without you driving each one.
Courses that go deeper
This pillar alone has 50 courses, from complete-beginner orientation through advanced prompting, AI agents, and building real websites and apps with AI. All 50 are free on every AIVX Labs plan, including Free. A few starting points:
- AI for Complete Beginners
- ChatGPT Masterclass, Claude Masterclass, Gemini Masterclass, Perplexity Masterclass
- Prompt Engineering 101 and Advanced
- AI Agents Explained
- Build Websites with AI, Build Apps with Claude

Once you can direct AI to produce work you'd put your name on, the next real question is what to actually sell with it — covered in Make Money with AI.
Every course and tool mentioned here is included free on AIVX Labs.
Start freeFrequently asked questions
How do I start using AI if I've never used it before?
Open ChatGPT or Claude and describe a real task you already need to do this week — an email, a summary, an outline — with as much context as you'd give a new employee. Read the result, tell it what's wrong, and ask it to fix that specific thing. That loop (describe, review, refine) is the entire skill; everything else is refinement.
Is it too late to learn AI?
No. The tools change monthly, but the underlying skill — giving clear instructions and iterating on the output — doesn't reset every time a new model ships. Someone who learns that skill today is not behind someone who started a year ago in any way that matters.
Do I need to learn to code to use AI effectively?
No, for most use cases. Writing, research, content, and business tasks need prompting skill, not code. Coding becomes useful only if you want AI to build software or automate technical workflows directly.
What's the difference between using AI and prompt engineering?
"Using AI" is the broad skill of getting useful output for a task. Prompt engineering is the more deliberate practice of structuring instructions — role, context, format, constraints, examples — to reliably get a specific kind of output, especially for repeatable or complex tasks.
