- **Iterate** — "make it warmer," "shorter," "add an example" — until it's right.

No technical skills required — see [learning AI without coding](/blog/how-to-learn-ai-without-coding).

## What is Claude best at?

- **Writing** — natural prose and editing that needs nuance.
- **Long documents** — summarizing and reasoning over big inputs.

## How to prompt Claude well

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](/blog/how-to-write-a-prompt). And as with any model, [verify important claims](/blog/spot-ai-hallucinations).

## Claude vs ChatGPT: which should you use?

Use Claude when text quality matters most — long writing, careful reasoning, code. Use ChatGPT as the more versatile all-rounder with the biggest ecosystem. Many people keep both. The full breakdown is in [ChatGPT vs Claude](/blog/chatgpt-vs-claude). Whichever you pick, the skill of directing it — [AI fluency](/blog/what-is-ai-fluency) — matters more than the choice.
