A field-manual guide to claude ai: how the assistant runs in a browser, how to prompt it, attach a file, switch models and keep your threads saved for next time.
For most people claude ai is a browser tab: open the site, sign in, and an empty prompt is ready. Type a request and claude ai answers in plain language; attach a long file and claude ai reads it before it replies. Because claude ai keeps your threads, you close the tab and reopen the same conversation tomorrow. To a beginner, claude ai should feel a lot like texting a quick, unflappable colleague — with no install and no setup in the way.
Ask the way you would a person; there is no syntax to memorise.
Drop in a document or image and it is understood before the reply.
The claude ai app keeps a lot behind a plain screen. Switch the model when you want a quicker or a deeper answer, and claude ai remembers the pick for that thread. Gather related work into a project so claude ai carries the right context, and let it turn a long answer into a tidy document beside the chat. None of it is required — a first claude ai prompt is just typing and reading — but the room is there as you go.
A fast one for quick notes, a deeper one for harder problems.
Group files and threads so the assistant sees the whole picture.
Whatever you open, it is one Claude account underneath. A thread you start in the browser appears in the desktop app, because both read the same history. One sign-in is enough for Claude to hold your chats, projects and settings aligned wherever you pick it up.
Every thread in a single account, web or app.
Begin on the laptop, resume on the phone, lose nothing.
If you write software, claude code carries the same assistant into your terminal, where it reads a project and edits with your approval. It is the same account as claude ai in the browser, so however you arrived — a claude ai prompt, a look at claude code, or a first question about models — the work waits behind one sign-in.
Illustrative examples of everyday use, not a promise of any specific result.
Nothing to install; the whole assistant opens in a tab.
It puts the same saved threads a shortcut from your work.
