Prompt Templates That Work
Copy, customize, and use. These patterns get better results than "just asking."
Analysis Framework
Reports, document review, strategic analysisI need you to analyze [TOPIC/DOCUMENT]. Please structure your analysis as: 1. Executive Summary (3 sentences max) 2. Key Findings (bullet points) 3. Risks/Concerns 4. Recommendations 5. Next Steps Be specific and actionable. Flag anything that needs human review.
Email Drafting
Professional communication, outreachWrite an email with these parameters: - To: [RECIPIENT + their role] - Purpose: [WHAT YOU WANT] - Tone: [professional/friendly/urgent] - Key points to include: [LIST] - Constraints: [word limit, what to avoid] Draft 2 versions: one concise, one detailed.
Code Review
Development, code qualityReview this code for: 1. Bugs or logic errors 2. Security vulnerabilities 3. Performance issues 4. Readability improvements For each issue found: - Severity (critical/medium/low) - Line number - What's wrong - How to fix it [PASTE CODE]
Meeting Prep
Sales calls, presentations, negotiationsI have a meeting about [TOPIC] with [ATTENDEES]. Help me prepare: 1. What questions should I anticipate? 2. What data/examples should I have ready? 3. What are the likely objections and how do I address them? 4. What's my ideal outcome and how do I steer toward it? Context: [BACKGROUND]
Enterprise Setup Checklist
Rolling out AI tools to your team? Don't skip these.
Define use cases first
Don't just buy licenses—identify 3-5 specific workflows you want to improve
Start with a pilot group
10-20 power users who will actually use it daily and give feedback
Create usage guidelines
What's OK to put into AI tools? What's not? Make it clear.
Set up SSO/enterprise accounts
Consumer accounts don't have admin controls or data protection
Train, don't just deploy
2-hour training session = 10x more adoption than just sending login links
Measure what matters
Time saved, quality improvements, adoption rate. Pick 2-3 metrics.
Plan for ongoing support
These tools update constantly. Someone needs to stay current and share tips.
