First steps with AI

From zero to your first results — a practical guide for beginners and marketers

For beginners

What you need to know to get started

What AI actually is

AI isn't a magic box that knows all the answers. It's a tool that processes text, recognizes patterns and generates probable answers based on billions of examples. It works best as a smart assistant — not as an infallible expert.

What AI can and can't do

✓ Can

  • Write and edit texts
  • Summarize long documents
  • Translate between languages
  • Generate ideas and brainstorm
  • Explain complex concepts simply
  • Help with code
  • Analyze data and documents
  • Answer questions from all kinds of fields

✗ Can't

  • Access the internet in real time (most models)
  • Guarantee 100% factual accuracy
  • Know about events after its training date
  • Read your mind — it needs context
  • Replace an expert in critical decisions
  • Handle confidential data safely
  • Remember previous conversations (without setup)
  • Always say "I don't know" — it would rather make up an answer

Where AI hits its limits

🔴

Hallucinations

AI can confidently state false information. Always verify facts, numbers and quotes against external sources.

🟡

Knowledge cutoff

Models have a date up to which they were trained. They don't know about events after that date — for current info, use Perplexity.

🟠

Data privacy

Don't put confidential company information, personal client data or internal documents into AI without your company's approval.

Tip from practice

Learn which tasks your chosen AI is best at. Every model has its strengths and weaknesses, and there is no AI that handles every task best.
