Kettio vs SaliencyLab

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.

SaliencyLab is an ad-testing platform for brands and agencies assessing creative before media spend. Its RoastIQ diagnostic evaluates creative on five KPIs: Beat the Skip, Get Noticed, Brand Impact, Sell Proposition, and Build Brand. BuyerLens uses synthetic-user scenarios to explore possible buyer resistance; these are not interviews with a real consumer panel. The Hugo AI agent can run diagnostics, explore those scenarios, query benchmarks, and show its reasoning trace in one conversation. RoastIQ accepts MP4, MOV, JPG, PNG, and WebP, with videos up to 60 seconds; GIF and HEIC are unsupported. Listed ad channels include Instagram Feed, Reels and Stories, TikTok, YouTube Pre-roll and Shorts, Facebook Feed, and Display, but not TV. SaliencyLab describes its KPI scores as modeled diagnostics, not forecasts of sales or in-market success. The web and API offering has a free plan with 10 analyses per month. Pro costs €99/month and adds BuyerLens and Hugo. REST API and webhooks are in private preview.
