Kettio
What it is
Kettio evaluates advertising creative for a selected buyer, platform, and conversion goal, then returns a relative ranking with a written rationale and confidence signal. AI respondents modeled on that buyer assess each ad separately, and their responses are combined into a directional result. Results identify the leading ad, explain why it leads, indicate confidence, and suggest improvements; live media remains the final proof. Inputs include images, videos, copy, static ads, user-generated content, product shots, and full ad packages. The product offers a REST Ranking API and local MCP server. API access is included with Professional, while Free and Starter accounts must upgrade to create an API key. A request accepts up to 20 images, with 60 scoring evaluations per minute per API key. App and API rankings share the monthly ad allowance, and requests stop when it is used up. Free scores 20 ads monthly; Starter is $29.99 a month and Professional is $139 a month. High-volume video ingestion and turnaround are scoped with founding pilots while the bulk workflow is being productionized. Kettio describes scores as directional and says they do not guarantee CPA, ROAS, or purchases.
