Kettio

Overview

Kettio is a creative-ranking tool for teams choosing ads against a defined buyer, platform, and conversion goal. It is best suited to agencies and DTC teams managing a regular flow of creative; its main value is a reasoned relative ranking, not a forecast of campaign results.

Key features

Kettio uses AI respondents modeled on a selected buyer persona. They assess each ad independently, and the responses are combined into a directional ranking. Results identify the leading ad, explain its position, show confidence, and suggest improvements. That makes Kettio useful for prioritizing what to test next, but not for replacing live media: its scores do not guarantee CPA, ROAS, or purchases.

Creative inputs include images, videos, copy, static ads, user-generated content, product shots, and full ad packages. Automated experiment types, advanced creative reporting, and ad-library import broaden the workflow beyond image comparisons. The back-test application lists Meta and TikTok creative volume and lets applicants enter other platforms, such as Google.

Teams can apply for a blind back-test of past creatives. Kettio ranks them without showing spend or outcome labels, then compares the ranking with actual results. This can help agencies and DTC teams producing 50 or more creatives a month assess whether the rankings are useful for their work, though the comparison is not a guarantee of future performance.

The REST Ranking API accepts up to 20 images per request and 60 scoring evaluations per minute per API key. App and API rankings draw from the same monthly ad allowance, and requests stop when that allowance is exhausted. High-volume video ingestion and turnaround are scoped with founding pilots while a dedicated bulk-video workflow is being productionized, so teams with substantial video throughput should discuss their needs before committing.

A local MCP server is also available. Professional includes API access; Free and Starter accounts must upgrade to create an API key. The privacy policy describes encryption in transit and at rest, TLS/SSL, Firebase Authentication, security audits, access controls, and incident monitoring. Prompts and generated assets may be used to improve AI models by default; users can opt out in Privacy Settings.

Pricing

Kettio has a free plan and two month-to-month paid plans. The free tier is a no-cost way to try small comparisons, but its 20 monthly scored ads, two ads per comparison, and four pre-built buyer personas constrain repeated or audience-specific work.

• Free — 0.00 USD per free: 20 ads scored each month, two ads per comparison, and four pre-built buyer personas. API key creation requires an upgrade, and rankings use the same monthly allowance as app usage.
• Starter — 29.99 USD per month, billed month-to-month: 100 ads ranked each month, 10 audience profiles, 50 ad generation credits, and Meta Ad Library access. It suits smaller teams that need more comparisons and profile choice than Free, but it does not include API access.
• Professional — 139.00 USD per month, billed month-to-month: 500 ads ranked each month, unlimited audience profiles, 500 ad generation credits, API access, and priority support. It is the clearest fit for higher-volume teams or workflows that need API keys; the shared monthly allowance still caps app and API rankings.

Professional is the only plan with API access and priority support. For questions, the company lists [email protected].

Platforms

Kettio is available on web and through an API. Its platform coverage includes TikTok, Instagram, Meta (Facebook), and general display. The back-test application specifically lists Meta and TikTok and accepts applicant-entered platforms such as Google.

Who it's for

Kettio makes most sense for creative teams that want a structured way to compare ads before putting them into live media, particularly agencies and DTC businesses producing at least 50 creatives a month. Smaller teams can start on Free, while teams that need many audience profiles, higher monthly volume, or API access have a reason to consider Professional. It is a weaker fit for buyers seeking guaranteed performance predictions or high-volume video turnaround without first scoping a pilot.

Pros and cons

• Pro: Rankings include rationale, confidence, and suggested improvements, giving teams more to act on than a winner alone.
• Pro: The blind back-test compares rankings with past outcomes without exposing spend or labels during ranking.
• Pro: Professional combines 500 monthly rankings, unlimited audience profiles, API access, and priority support.
• Con: Scores are directional and cannot assure CPA, ROAS, or purchases, so live campaign results remain decisive.
• Con: App and API usage share a plan allowance, and rankings stop when that monthly quota runs out.
• Con: Free and Starter cannot create API keys, and bulk video handling is still being productionized.
• Con: Prompts and generated assets may be used for model improvement by default unless users opt out in Privacy Settings.

Verdict

Choose Kettio if your team needs a repeatable, explainable way to rank a steady stream of creative and can treat the result as a shortlist for live testing. Its rationale, confidence signal, and blind back-test are the strongest reasons to use it. Look elsewhere if you need a performance guarantee, unscoped high-volume video processing, or API access on a lower-cost plan.
