How Claude differs from ChatGPT (prompt implications)

Claude responds well to direct, natural language. Unlike ChatGPT, it doesn't need heavy role-framing to produce expert-level output — but it benefits from clear context, explicit format requirements, and XML tags for multi-part tasks.

Key Claude prompting principles:

• Be direct. Analyze this and find the three biggest risks beats You are an analyst. Your task is to analyze...
• Use XML tags for structure: <document>...</document> <task>...</task>
• For long documents: paste the full text first, then ask your question — Claude's 200K context window handles this
• Specify format explicitly: Reply in a numbered list, Use a markdown table, Write under 100 words

Generating Claude-optimized prompts

Claude's prompt structure is different enough from ChatGPT that using a model-aware prompt generator pays off. PromptMake's Claude mode produces prompts structured for Claude's preferred format — direct, context-first, with explicit output constraints — rather than the role-heavy GPT-style format.
