How to Use Claude: A Beginner's Guide (2026)

To use Claude, go to claude.ai (opens in a new tab) (or download the desktop or mobile app), sign up for a free account, and type what you want into the message box, the way you'd brief a capable coworker. That's genuinely all you need to start. Getting good results takes a bit more: giving Claude context, picking the right model, and setting it up with your files and tools so you're not re-explaining yourself every time. This guide walks through all of it in order, with no tech background assumed.

TL;DR

Here's how to use Claude: sign up at claude.ai, then write prompts that say what you want, who it's for, and what "good" looks like. Upload files instead of describing them. Use Projects to keep instructions and reference documents in one place, connectors to let Claude read your Gmail, Drive, or calendar, and skills to save how you like recurring tasks done. The free plan covers chat, web search, file uploads, connectors, and up to five Projects; Pro ($20/month) adds more usage and the longer, multi-step task work that used to be called Cowork. The fastest way to learn is by doing real tasks, which is what our free Claude course is built around.

Step 1: Get Claude set up

You can use Claude three ways, all on the same account:

• Web: claude.ai (opens in a new tab) in any browser.
• Desktop: the Claude app for Mac or Windows. It's the better choice if you'll work with files on your computer. See Claude Cowork platforms for what each app supports.
• Mobile: Claude for iOS or Android.

You need to be 18 or older and in a supported country. Sign up with an email address or a Google account, and you're on the Free plan.

Free vs Pro: which do you need?

Start on Free. Upgrade when you keep hitting the usage limit mid-task, or when you want Claude to take on longer, multi-step work for you. The full breakdown is in Claude Cowork pricing.

Step 2: Have your first real conversation

Open a new chat and type. Don't start with "hi" or a test question. Start with a real task you'd otherwise spend 20 minutes on:

I run a small landscaping company. A customer emailed asking why our quote
is $800 higher than a competitor's. Here's their email: [paste it].

Draft a reply that explains we include haul-away and a 1-year plant guarantee,
stays friendly, and doesn't sound defensive. Keep it under 150 words.

Then reply to what comes back instead of starting over. "Shorter." "Less formal." "Lead with the guarantee." Claude gets better the more you steer it inside the same conversation. Start a new chat when you switch to an unrelated topic, so old context doesn't muddy the new task.

Two more controls are worth knowing on day one:

• The + button next to the message box (or typing /) opens attachments, connectors, and other options.
• The model selector sits under the message box on web and desktop, and at the top of the screen on mobile.

Step 3: Write prompts that get good answers

Most bad Claude answers come from thin prompts. A good prompt usually covers four things:

1. The task: what you want made or done.
2. The context: who you are, who it's for, and anything Claude can't know on its own.
3. The constraints: length, tone, format, what to avoid.
4. What good looks like: an example, or "the reader should come away knowing X."

You don't need special wording or tricks. Write it the way you'd brief a sharp new hire on their first week. If the answer misses, say why it missed ("too salesy, my customers are retirees") rather than just "try again."

A useful habit: ask Claude to interview you first.

Before you write anything, ask me the 5 questions you'd need answered
to do this well.

Step 4: Pick the right model

Claude comes in several models. As of October 2026, the current ones are Haiku 5.5, Sonnet 5.5, Opus 5.5, and Fable 5.1, with more of them available on paid plans. A simple rule:

• Haiku: quick, simple jobs like rewording, short summaries, and quick questions.
• Sonnet: the everyday default for writing, analysis, and most work tasks.
• Opus and Fable: the most capable. Use them for long documents, hard reasoning, and multi-step work where quality matters more than speed.

You can also choose how much effort Claude puts in and whether it uses extended thinking, which helps on problems that need working through. If you're unsure, leave the default and only switch when an answer feels shallow.

Step 5: Give Claude your files

Claude is at its best working on your material, not general knowledge. Drag a PDF, Word doc, spreadsheet, or screenshot into the chat (or use +), then ask:

• "Summarize this contract and list anything that would cost me money if I miss it."
• "This spreadsheet is last quarter's jobs. Which customers ordered more than twice?"
• "Here's a screenshot of our website's homepage. What's confusing to a first-time visitor?"

Claude can also create files: Word documents, spreadsheets, slide decks, and PDFs you can download. Ask for the format by name ("give me this as an Excel file").

Step 6: Set Claude up so it remembers how you work

This is where most people stop, and it's the step that makes the biggest difference. Without setup, every chat starts from zero.

Projects: your standing brief

A Project is a workspace with saved instructions and reference files. Every chat inside it starts with Claude already knowing your business, your tone, and your documents. Make one per area of work, such as "Customer emails" or "Marketing," and put your price list, FAQ, and a paragraph about your business in it. Free accounts get up to five. Full walkthrough: Claude Projects explained.

Connectors: let Claude see your tools

Connectors link Claude to apps like Gmail, Google Drive, Google Calendar, Slack, and Notion so it can look things up there, and for some apps take actions. Go to Customize → Connectors, choose an app, and sign in. Then turn it on in a chat from the + menu. Claude only sees what your own account can already see. See the full Claude connectors guide.

Skills: save how you like things done

A skill is a saved set of instructions for a recurring task, like "write proposals in our format" or "turn meeting notes into action items our way." Claude uses it automatically when the task comes up. You can add skills from Customize → Skills on any plan, including Free (code execution needs to be on under Settings → Capabilities). Learn how in how to create Claude skills.

Memory

Claude can remember useful facts about you across conversations, and you can review what it has saved. Treat memory as a convenience, not a filing cabinet: put anything important into a Project, where you control exactly what's there.

Step 7: Hand off bigger tasks (what used to be Cowork)

Chat is turn-by-turn: you ask, it answers. For bigger jobs, Claude can take a goal and work through the steps on its own, reading files in a folder, pulling from your connected apps, browsing, and producing finished documents. That used to be a separate mode called Claude Cowork.

Since September 16, 2026, Anthropic has been merging Cowork into regular Claude (opens in a new tab). On Pro and Max, there's no mode to pick anymore: you describe the outcome, and Claude decides whether it needs a quick answer or a longer piece of work. Team and Free are getting the merged version later, so on those plans you may still see Chat and Cowork separately. The details are in Claude chat vs Cowork.

Good first tasks to hand off:

Go through the invoices in my "2026 Receipts" folder and build a spreadsheet
with date, vendor, amount, and category. Flag anything over $500.

Check my calendar for next week and draft a prep note for each client
meeting using our last email thread with them.

Learning this way of working is exactly what our free Claude course teaches, with practice files you work through inside Claude.

What Claude gets wrong (and what to check)

Claude is very good, but not infallible. Build these habits from day one:

• It can be confidently wrong. Facts, numbers, quotes, and legal or medical details need checking against a real source, especially when they matter.
• It doesn't know recent events unless it searches. If you need current prices, news, or rules, ask it to search the web and look at the sources it cites.
• It only knows what you give it. A vague answer usually means a vague prompt. Add context before blaming the tool.
• Review before anything goes out. Read every email, contract change, or customer-facing document before you send it. Claude drafts; you approve.
• Mind what you paste. Check your plan's privacy settings, and don't paste client data your agreements don't allow you to share.

Where to go next

Once the basics feel natural, pick one recurring task and set it up properly with a Project, a connector, or a skill. For concrete work examples (emails, meeting prep, SOPs, proposals), read how to use Claude for work.

Frequently asked questions

Is Claude free to use?

Yes. The Free plan includes chat on web, desktop, and mobile, web search, file uploads and file creation, connectors, memory, and up to five Projects. Usage is limited per session and resets every five hours. Pro costs $20 a month ($17 a month billed yearly) for more usage and extra features.

How old do you have to be to use Claude?

You must be at least 18 years old to use Claude, and you need to be in a country where Claude is available.

What is the best way to use Claude for beginners?

Start with a real task, not a test question. Give Claude context about who you are and who the result is for, upload files instead of describing them, and keep refining in the same conversation. Once that feels natural, set up a Project so Claude remembers your business between chats.

How do I use Claude Cowork?

On Pro and Max, Cowork has been merged into regular Claude since September 16, 2026, so you just describe the outcome you want in any conversation and Claude works through the steps. On plans that haven't received the merge yet, you may still see a separate Cowork option in the app.

How do I use Claude Projects?

Create a Project from the sidebar, add instructions describing your business and how you want Claude to respond, and upload the reference files you use often. Every chat you start inside that Project begins with those instructions and files already loaded. Free accounts can create up to five Projects.
