What you get, and what it costs

What you get. One report on how Claude recommends the products in your category: which it picks for each kind of buyer, what it says for and against you and your competitors, and how that has moved from one release to the next. It is delivered by email, as a PDF, within [delivery window] of payment.

How the price is set. A report needs five briefs for each buyer in each region, each put to every Claude release on the timeline, and a tenth of them asked twice. Before you buy, we estimate what those answers will cost at the AI provider’s list prices, drawing each answer’s length from the answers that release has given before, a thousand times over. The price is the cost that 99 runs in 100 stay under, multiplied by 1.5. It is shown at checkout, in US dollars, paid once, and does not change after you pay.

An example. Our vacation-rental study: five buyers in two regions, 49 briefs, each put to every release from September 2025 to September 2026, a tenth of them twice, 486 answers in all. Cost at the 99th percentile: $12.04. Price: $18.06.
