Define the options. Compare what matters.
Replace the bracketed sections with the alternatives, criteria and constraints relevant to your decision.
Act as a structured research and comparison specialist. TASK: Research and compare the following options, products, services, strategies or alternatives. TOPIC: [What are you comparing?] OPTIONS TO COMPARE: - [Option 1] - [Option 2] - [Option 3] PURPOSE: [Explain why you are comparing them and what decision you need to make.] TARGET USER / SITUATION: [Who is this comparison for? Describe the user, business, project or use case.] COMPARISON CRITERIA: - [Criterion 1] - [Criterion 2] - [Criterion 3] - [Criterion 4] IMPORTANT CONSTRAINTS: [Budget, location, deadlines, technical requirements, availability, compatibility or other limits.] RESEARCH REQUIREMENTS: - Separate verified facts from assumptions. - Identify where information may be outdated, uncertain or incomplete. - Do not invent specifications, prices, statistics or claims. - When current information is required, clearly indicate what should be verified from reliable sources. - Consider both advantages and disadvantages. - Avoid recommending an option only because it is the most popular. - Evaluate each option against the actual criteria and use case. OUTPUT FORMAT: 1. Executive Summary 2. Comparison Table 3. Option-by-Option Analysis 4. Advantages and Disadvantages 5. Key Differences 6. Risks / Limitations 7. Best Choice by Use Case 8. Final Recommendation 9. Information That Should Be Verified For the final recommendation, explain WHY the recommended option is the strongest fit based on the stated requirements.
Use the prompt effectively.
Define the decision
Explain what you are trying to choose and why the comparison matters. This keeps the research focused on the real decision.
Set clear criteria
List the factors that actually matter, such as price, ease of use, features, reliability, compatibility or long-term cost.
Add your constraints
Include budget, location, deadlines, technical requirements or anything else that could rule out an otherwise good option.
Verify important claims
For prices, availability, regulations and other changing information, check reliable current sources before making a final decision.
Turn a broad comparison into structured research.
Topic: Compare three website hosting options for a small content and tools website.
Options: Cloudflare Pages, GitHub Pages, Netlify.
Purpose: Choose a free-first hosting platform that can support future growth.
Criteria: Cost, deployment workflow, custom domains, performance and future serverless capabilities.
Executive Summary: Compare the three platforms against the stated requirements rather than ranking them generically.
Comparison Table: Show cost, deployment method, custom-domain support, performance considerations and expansion options side by side.
Recommendation: Identify the strongest fit for the stated use case and explain the trade-offs that influenced the decision.
Make comparisons more useful.
Compare against a use case
A product or service is not simply 'best'. It is best for a particular situation, budget and set of requirements.
Ask for uncertainty
Tell the AI to flag missing, outdated or uncertain information instead of filling gaps with confident-sounding guesses.
Weight important criteria
If one factor matters more than the others, state that clearly so the final recommendation reflects your real priorities.
