Start here. Fifteen minutes, no jargon.
You do not need to understand how AI works to get real use out of it. Five short lessons, each ending with one thing to try. Read them in order or jump to what you need.
What is what
Three words cover almost everything you will hear.
- The app
- What you open and type into: ChatGPT, Claude, Gemini, Copilot. Think of it as the car.
- The model
- The "brain" inside the app, with names like GPT-6, Claude Opus or Gemini. Think of it as the engine. Apps swap in newer engines several times a year, which is why the names keep changing.
- The tool
- An app built for one job: Gamma makes slides, Suno makes songs, Otter writes meeting notes. Most of them use one of the big models underneath.
Free or paid
Start free. Pay only when you keep hitting a limit.
- Free plans are real. Enough for questions, emails, summaries and learning. You get fewer messages per day and sometimes an older or smaller model.
- About $20 a month is the standard paid plan. It buys the newest model, many more messages, and extras like file uploads or image creation.
- You do not need three subscriptions. The big assistants are closer to each other than their marketing suggests. Pick one, use it for a month, then decide.
- Specialist tools charge separately. Slides, video, music and meeting tools each have their own free tier and price.
How to ask
There are no magic words. Talk to it like a capable new colleague who knows nothing about your situation.
Say who it is for and why
"An email to a customer who is annoyed about a late delivery" beats "write an email".
Give it the material
Paste the text, upload the file, list the facts. It cannot guess what is in your head.
Say what you want back
Length, tone, format: "three short paragraphs, friendly, no jargon".
Then correct it
It is a conversation. "Shorter." "Less formal." "You missed the deadline, add it." The second and third answers are usually the good ones.
Write about our product.
Write a 100-word description of our reusable water bottle for our online shop. Buyers are hikers. Mention that it keeps drinks cold for 24 hours and fits a bike holder. Friendly, no exclamation marks.
Stay safe
Two habits protect you from nearly every problem.
Check what matters
AI can state something false in a confident voice. It is not lying; it is predicting plausible words. Always verify:
- Numbers, dates, prices and calculations
- Names, quotes and sources (ask for a link, then open it)
- Anything legal, medical or financial: use it to prepare questions, not to decide
Think before you paste
What you type is sent to the company that runs the app. Do not paste:
- Passwords, card numbers, ID or passport numbers
- Other people's private details: health, salaries, addresses
- Confidential work documents, unless your employer has approved the tool
Skills and beyond
Once the basics feel easy, these four ideas are what make an assistant truly useful. You can ignore all of them for your first weeks.
Skills
Ready-made instructions that teach an assistant one job: build a proper Word report, review a contract, design a slide deck your way. You add a skill once and it is used whenever the task comes up.
Connectors (MCP)
Plugs that let the assistant reach your other apps: read your calendar, search your files, update a spreadsheet, instead of you copying things back and forth.
Agents
An assistant that does a multi-step job on its own, such as researching a topic across many pages and writing the summary, and reports back when it is done.
Local models
Smaller models that run on your own computer. Free, offline and private, but less capable than the big online ones.
