Claude excels at: long-form writing, nuanced reasoning, following complex multi-step instructions, and maintaining context over very long conversations. It's more likely than other models to push back if something seems wrong — which is actually useful.
Claude is less strong at: real-time web access (on free tier), image generation, and some math problems where GPT-4 has an edge.
Claude is trained to respond well to structured inputs using XML-style tags. For complex requests, organize your prompt like this:
"<task>Write a competitive analysis</task>
<context>We are a B2B SaaS startup in project management</context>
<competitors>Asana, Monday.com, Linear</competitors>
<format>Table with columns: Feature, Us, Competitor 1, Competitor 2</format>"
Claude sometimes hedges or adds qualifiers. If you want a direct answer: "Give me a direct recommendation without caveats." or "Skip the disclaimer and just answer the question."
Claude.ai lets you set custom instructions that apply to every conversation. Set your role, preferred tone, and any standing rules once — don't repeat them in every prompt.
After getting a response, ask: "What are the weaknesses of what you just wrote?" or "What would a critic say about this?" Claude gives genuinely useful self-critiques that improve the final output.
Claude handles very long context windows. Paste entire documents, long email chains, or code files — Claude maintains understanding across the full length better than most models.
For writing and reasoning: usually yes. For image generation and plugins: ChatGPT wins. Most power users use both. See our full ChatGPT alternatives comparison.
