Frequently asked questions for beginners
Honest answers to the questions everyone asks before getting started with Claude Code, without technical jargon, without detours.
Got questions? That's normal. Here are honest answers to the most common ones, no sugarcoating.
Can it break my computer?
No. Claude Code is a software tool like any other. It doesn't touch your system files, doesn't modify your hardware, and does nothing without your explicit approval.
More specifically: Claude Code always shows you what it plans to do before doing it, and asks for your permission. You can decline at any time by typing n or pressing Ctrl+C.
The worst that can happen
If you make a mistake within a project, you can always revert using Git (a version tracking system). Claude Code itself can help you "undo" its own changes if something doesn't work for you.
Does the AI see my personal files: photos, documents, emails?
No. Claude Code only accesses the folder where you launch it, and only the files you explicitly show it in the conversation.
Your family photos, personal documents, emails, browser-saved passwords, all of that is invisible to Claude Code. There's no connection between your browser, your cloud storage, or your personal applications.
The only exception: if you use MCPs (optional connectors) that give access to specific tools like Gmail or Google Drive. But those connections must be explicitly set up by you, they don't exist by default.
What's the difference between ChatGPT and Claude Code?
Good question. Both are artificial intelligence, but their use is very different.
| ChatGPT / Claude.ai | Claude Code | |
|---|---|---|
| Interface | Website (chat in the browser) | Terminal (command line) |
| What it does | Answers your questions, writes text, explains concepts | Reads, creates, and modifies files on your computer |
| File access | No (you copy-paste text) | Yes (in the current folder) |
| Ideal for | Research, writing, conversation | Development, automation, file management |
| Cost | Free or separate subscription | Claude Max subscription or API key |
In short: ChatGPT and Claude.ai are web chatbots. Claude Code is an assistant that works directly on your files.
Is it legal?
Yes, completely legal. Claude Code is a commercial product from Anthropic, a legally incorporated American company. Using Claude Code is like subscribing to any other SaaS software.
The only legal limits that apply are the same as for any tool: don't use it to create illegal content, spam, or to circumvent security systems.
Do I need Internet to use it?
Yes, an Internet connection is required. Claude Code sends your requests to Anthropic's servers and receives responses. Without a connection, the tool can't function.
However, files created or modified remain on your computer, even offline.
Does it work on Chromebook / tablet / phone?
No, not directly. Claude Code requires a real operating system with a terminal (macOS, Windows, Linux). Standard Chromebooks, tablets, and phones don't support this type of installation.
If you have a Chromebook, there's a workaround via "Linux (Beta)" in settings, but it's fairly technical and not recommended for beginners.
To get started comfortably, you need:
- A Mac (any model from the last 5 years)
- A Windows 10 or 11 PC
- A Linux computer
Is it free?
This guide is 100% free. But the Claude Code tool itself has a cost.

Getting started without spending
Anthropic typically offers a trial credit when you create an account. You can test Claude Code for free for a few hours or days depending on your usage, before deciding whether to subscribe.
Can I cancel at any time?
Yes, no commitment. The Claude Max subscription is monthly and managed from your Anthropic dashboard. You can cancel whenever you want, no cancellation fees, no notice period.
If you use the API key (pay-as-you-go), there's no subscription at all, you only pay for what you use.
Is it dangerous for my job?
No, quite the opposite. Claude Code is an augmentation tool, not a replacement.
Think of the calculator: it didn't eliminate accountants, it let them work faster and focus on higher-value tasks. Claude Code does the same for intellectual tasks.
People who master these tools will be more productive, more creative, and more competitive in the job market, not the other way around.
Do I need to know how to code to use Claude Code?
No, it's not required. Claude Code can help with non-technical tasks: writing emails, analyzing documents, creating presentations, organizing data in files...
That said, the more you know what you want and the more you can verify the result, the better. Some basic knowledge (like understanding what an HTML file or a CSV spreadsheet is) will help you get more out of the tool.
Will Claude Code do everything for me?
No, and that's a good thing. Claude Code is an assistant, not an autonomous robot. It does what you ask, but you remain the decision-maker.
In practice, you'll need to:
- Write clear requests
- Verify results
- Give your approval before each important action
- Correct and adjust when the result doesn't match what you wanted
It's a constant back-and-forth. The quality of that dialogue is what makes the difference between a frustrating experience and a productive one.
What if Claude Code makes a mistake?
It's expected, and manageable. Claude Code sometimes makes mistakes. It can misunderstand your request, miss a detail, or suggest an incorrect solution.
Here's how to react:
- Point out the error: simply say "that's not what I wanted, here's what's wrong..."
- Be specific: the more you explain what's wrong, the better it can correct itself
- Undo if needed: you can always revert with Git, or ask Claude Code to undo its changes
Is my data private?
Anthropic collects conversations to improve its models, but you can configure your account to limit this. Data is stored on American servers.
Never share with Claude Code: passwords, credit card numbers, confidential medical information, sensitive personal data of third parties.
Check Anthropic's privacy policy for full details.
