What it is
Kettio ranks ad creative for a selected buyer, platform, and conversion goal, returning a relative order, written rationale, and confidence signal. AI respondents modeled on the chosen buyer assess each ad separately; their responses are combined into a directional ranking. Results identify the leading ad, explain why it leads, indicate confidence, and suggest improvements, while live media remains the final proof. Inputs include images, videos, copy, static ads, UGC, product shots, and full ad packages. The service offers a REST Ranking API and a local MCP server. API access is included with Professional; Free and Starter accounts must upgrade to create a key. Requests can contain up to 20 images, and each API key is limited to 60 scoring evaluations per minute. App and API rankings share the monthly ad allowance, and requests stop when it is used up. High-volume video intake and turnaround are handled with founding pilots while a bulk workflow is being prepared. The free plan scores 20 ads each month; Starter costs $29.99 a month and Professional costs $139 a month, both billed month-to-month.
