Product comparison prompt
A copy-and-paste prompt for ChatGPT, Claude or Gemini that gets a professional product comparison on the first try, plus the cheapest model that does it well.
What most people type
compare our premium plan vs basic plan for our coffee subscription so people can pick. premium is $29/mo 2 bags any roast free shipping, basic $18/mo 1 bag house roast
It works, but the AI has to guess your basic shipping cost, call to action and bag size, so the first answer usually needs another round. The version below asks for exactly what a professional would deliver.
The better prompt
Write a comparison of our two coffee subscription plans to help customers choose between them. Plan details: - Premium: $29/mo, 2 bags of any roast, free shipping - Basic: $18/mo, 1 bag of house roast, [shipping cost for Basic] Format: a side-by-side table covering price, bags per month, roast choice and shipping. Follow it with a short "Which plan is right for you?" section with 2-3 customer types for each plan, based only on the details above. Finish with one clear call to action: [action, e.g. link or button text]. If a per-bag price comparison would help, calculate it and show the math. Don't invent details about the coffee, sourcing, bag size, freshness, cancellation or other perks. Use [bag size], [skip or cancel policy] and [brand name] only if relevant. Tone: [friendly, simple, matching our brand voice].
Replace the [brackets] with your details before you send it: shipping cost for Basic, action, e.g. link or button text, bag size, skip or cancel policy, brand name, friendly, simple, matching our brand voice.
