Claude Prompt Library

The best Claude prompts are specific, structured, and include context about the desired output. Our library features 30+ tested templates across coding, writing, analysis, creative, business, and education categories. Each prompt includes clear instructions, output formatting, and placeholders for your specific content.

Effective AI prompts follow a clear structure: define the role, provide context, specify the task, set constraints, and describe the desired output format. Be specific about what you want and include examples when possible. Avoid vague instructions and always tell the model what NOT to do if relevant.

Claude responds well to structured prompts with explicit instructions, system-level context, and XML tags for organization. ChatGPT works similarly but has different strengths. Claude excels at longer, nuanced tasks and following detailed instructions, while both benefit from clear role definitions and output formatting.

It depends on complexity and budget. Claude 3 Haiku is ideal for short, simple prompts under 1000 tokens — it's fast and cheap.

Our tool shows token estimates and model recommendations for each prompt.
