Most of what Claude can do is not in the box you type into. This is a plain guide to the rest of it — written for people who have used a chatbot and never opened the menu.
There are six items in the left-hand menu of the Claude app. Most people open one, glance at it, and go back to typing — which is a reasonable response to an interface that puts a text box in the middle and everything else in a column you can collapse.
Meanwhile Claude can open your files, run for an hour without you, remember what it learned last Tuesday, connect to tools you already pay for, and hand you a finished spreadsheet instead of a wall of text to reformat. None of that lives in the box.
Prompting is chapter nine. It matters, and it is not the thing.
Claude's paid certifications are not available to the public at all — they require an email address at a partner organisation. Every article selling you exam prep leaves that out.
A background task that needs your permission waits ten minutes, then denies itself and carries on. It reports success. You have to ask what it skipped.

Every factual claim was checked against Anthropic's own documentation in September 2026. Where two official sources disagreed, both are reported. Where something could not be verified, it says so.
