Claude is an AI assistant that's especially good at writing, long documents, and code. To use it well, give it context, a role, and clear instructions — then iterate. Here's how to start and what it's best for.
To use Claude, go to claude.ai (or the app), type what you want in plain language, and refine the answer with follow-ups. Claude is an AI assistant made by Anthropic, and it's especially strong at writing, careful reasoning, working through long documents, and code. It's free to start. The better your prompt — context, a role, clear instructions, and the format you want — the better Claude's output.
Getting started with Claude
Go to claude.ai or download the app and sign up — the free tier is enough to learn on.
Type a real request, e.g. "You are an editor. Tighten this paragraph and flag anything unclear: [paste]."
Iterate — "make it warmer," "shorter," "add an example" — until it's right.
The same recipe that works everywhere works with Claude: give context, assign a role, state the task, and specify the format. Claude rewards detail — it follows nuanced instructions closely, so spelling out exactly what you want (and what to avoid) gets sharp results. Full walkthrough: how to write a good AI prompt. And as with any model, verify important claims.
Claude vs ChatGPT: which should you use?
