How to Write Better AI Prompts: Complete Guide with Examples (2025)

How to Write Better AI Prompts in 2025

The quality of AI output depends almost entirely on the quality of your prompt. Here is a practical guide to writing prompts that get excellent results from ChatGPT, Claude, Gemini, or any AI tool.

The 5 Elements of a Great Prompt

1. Role

Tell the AI what role to play. This frames its response appropriately.

Example: “You are a senior marketing manager with 15 years of experience in B2B SaaS.”

2. Context

Provide relevant background information.

Example: “Our company sells project management software to teams of 10-50 people. Our average deal size is $5,000/year.”

3. Task

Be specific about what you want.

Bad: “Write me a marketing email.”

Good: “Write a follow-up email to prospects who attended our webinar but did not sign up for a free trial. The email should be under 150 words, include one specific benefit, and end with a clear CTA.”

4. Format

Specify how you want the output structured.

Example: “Format as a numbered list with bold headings. Keep each point under 50 words.”

5. Constraints

Set boundaries to improve quality.

Example: “Do not use jargon. Write at an 8th-grade reading level. Avoid cliches like ‘game-changer’ or ‘cutting-edge’.”

10 Prompt Templates You Can Copy

For Email Writing

“Write a [professional/casual/apologetic] email to [audience] about [topic]. Keep it under [X] words. The main goal is [desired action].”

For Blog Posts

“Write a [length] blog post about [topic] for [audience]. Include [number] practical examples. Use H2 and H3 headings. Write in a conversational but authoritative tone.”

For Code Review

“Review this code for: bugs, performance issues, security vulnerabilities, and readability. For each issue found, explain why it matters and provide a fix. Code: [paste code]”

For Data Analysis

“Analyze this data and provide: 1) Key trends, 2) Anomalies, 3) Three actionable recommendations. Present findings in a table format. Data: [paste data]”

For Meeting Summaries

Common Prompt Mistakes

• Too vague: “Help me with marketing” — add specifics
• Too long: Multi-paragraph prompts often confuse the AI — be concise
• No examples: Showing one example of desired output dramatically improves results
• Forgetting constraints: Without word limits and tone guidance, outputs tend to be verbose
