Everyone keeps talking about what Claude can do.
All I see is an empty text box.

So what is Claude, then – a search engine?

No. A search engine gives you places to look. Claude gives you a result.

You describe what you need – Claude thinks, looks things up if it has to, calculates, writes, and puts the finished thing in front of you.

And what do I have to install for that?

Nothing at all. Open a browser, sign in, start typing. There are apps for your computer and your phone too – but you need neither.

And you don’t have to learn how to ask properly. Put it the way you would say it to a colleague.

Good enough as a first message:
“I’ve got three quotes here for a new boiler. Tell me how they differ and what I should watch out for.”
nothing to set up, nothing to learn

Can I give it my own documents as well?

Yes – just drag them into the conversation. PDFs, photos, spreadsheets, text files.

Claude reads them and works on from there: summarising, comparing, pulling out numbers, answering questions about them.

Sometimes a window opens up on the right. What is that?

That is an artifact. When the result is no longer a sentence but a thing, Claude puts it beside the conversation instead of into it.

A document, an overview, a diagram – or a small application that actually runs.

And what if I don’t like something about it?

Say what should be different – Claude rebuilds it. You can also touch the text directly: highlight it and have it changed.

Every version is kept, so you can page back. You can download it, and publish it too: then you get a link to pass on.

Do I get a real Excel file too?

Yes. Claude can build real files – spreadsheets with working formulas, presentations, documents, PDFs.

It is built in a sealed-off area at Anthropic, not on your computer. You download the finished file.

Should I put everything into one conversation?

Better not. A conversation has a working memory, and it fills up – then things get sluggish and vague.

Rule of thumb: new topic, new conversation. It costs nothing and makes the answers better.

So do I start from scratch every time?

No. Claude remembers things across conversations and can look back at earlier ones. You can also just tell it “remember that”.

What it remembered you can look at, change and delete – or switch memory off entirely. For one-off things there is incognito: it shows up nowhere.

Incognito: no history, no memory, nothing stays
9/21
Can I bring some order to this?

That is what projects are for. Each one is its own workspace: its own conversations, its own documents, its own instructions – and its own memory.

Set it up once and it applies to everything inside. You don’t have to explain the background again in every conversation.

Does Claude know what happened yesterday?

Not by itself – its knowledge has a cut-off date. But it can look things up, and then it names its sources.

Two different buttons: search briefly fetches something from outside. Extended thinking fetches nothing at all but thinks harder – good for puzzles.

Search
a quick look outside
with sources named
“What does that cost right now?”

11/21
And if I want to know it properly?

Then use research. Claude keeps searching on its own, follows leads and checks several sources against each other – for one to three minutes.

What comes out is a report with evidence, not a quick answer. For comparisons, market overviews, decision papers.

Can it get at my calendar and my mail?

If you connect it, yes. You attach Drive, calendar, mail and a good deal more under Customize.

After that Claude fetches things itself. But only connect what you really need – and what you know.

It’s always too long for me.

Then change the style. There are ready-made ones – concise, formal, explanatory – and you can build your own.

For your own you simply give Claude a few lines that sound like you. From then on it writes that way.

Explanatorytakes you along when you want to learn

And when I’m out?

The same conversation, everywhere: browser, desktop app, phone. You open it wherever you happen to be.

On the phone you can simply talk instead of typing. Handy while walking – and for sorting out your thoughts.

There’s a name at the top. Do I have to change it?

Usually not. The default fits almost everything.

If a job is genuinely hard, take a stronger model. If it just has to be quick, take the small one. As of August 2026 they are called:

Fable 5the strongestnot on every plan
Opus 5the heavy jobsthinks thoroughly
Sonnet 5everyday workthe default
Haiku 4.5fast & cheapfor short things
when in doubt: leave it alone
16/21
How do I best put it?

State the goal, not the steps – Claude finds the way itself. And say how you can tell when it is done.

Give the context: who it is for, what for, and what must not happen. The clearer the task, the fewer rounds.

rather not
“Write something about our summer party.”
better
“An invitation to the summer party for the neighbours, half a page at most, friendly but not silly. Date and how to sign up must be in there.”
17/21
Can I actually rely on it?

Usually yes – but Claude can also be convincingly wrong, and it sounds just as certain as ever while doing it.

So: for anything that matters, ask where it came from. And have numbers worked out again rather than believing them.

Ask for the sourcewhere is that from?

And if a PDF says “delete everything”?

Good question – that is where the trap is. Claude reads web pages, e-mails and other people’s documents. None of that is an instruction from you.

Instructions come from you. Everything else is material to read. So with anything from outside, look more closely at what comes out.

What actually happens to what I write?

That is in the settings, and you decide it. There you set whether your conversations may be used to improve Claude.

Incognito conversations are never used for it – and never appear in your history either. For delicate matters the rule still holds: only put in what you would also hand to a service provider.

Incognitono history, no memory, never for training
Still truecredentials and other people’s secrets belong nowhere near it

And if I want more?

Then it goes on in stages – the question is always how far you let Claude at your things.

Here, in the conversation, everything passes through you: you put in, you take out. That covers an astonishing amount.

1 · In the conversationnothing to set up – you upload, you download
2 · CoworkClaude works directly in your folders
3 · Claude Codeterminal: Claude works on the whole machine – and keeps running without you

Oh. That’s not so bad after all.

Exactly. Start with a real job, not with a test.
