Kettio

Overview

Kettio ranks advertising creatives for a chosen buyer, platform, and conversion goal, with a rationale and confidence signal for each comparison. It suits teams that need a directional way to prioritize a steady flow of ads, especially agencies and DTC brands producing at least 50 creatives a month. The free plan is a useful starting point; teams needing more volume, audience profiles, or API access will need a paid plan.

Key features

Kettio models respondents around a selected buyer persona. Those AI respondents assess each ad independently, and their responses are combined into a relative ranking. Results identify the leading ad, explain why it leads, show confidence, and suggest improvements. This gives creative teams a reasoned shortlist rather than a promise of campaign performance: Kettio says its scores are directional and do not guarantee CPA, ROAS, or purchases. Live media remains the final proof.

Inputs include images, videos, copy, static ads, UGC, product shots, and full ad packages. Automated comparisons and advanced creative reporting make the product relevant across several creative formats, while ad-library import can help teams bring existing ads into the workflow. The back-test application covers Meta and TikTok creative volume and lets applicants enter other platforms, such as Google.

Teams can apply for a blind back-test that ranks past creatives without exposing spend or outcome labels, then compares the rankings with actual results. That offers a way to examine whether Kettio's directional rankings align with a team's historical outcomes. The application is aimed at agencies and DTC teams producing 50 or more creatives monthly, so lower-volume advertisers may find it a less natural fit.

The REST Ranking API and local MCP server extend rankings beyond the app. API access is included with Professional; Free and Starter accounts must upgrade to create an API key. Requests accept up to 20 images and are limited to 60 scoring evaluations per minute per key. App and API rankings draw from the same monthly ad allowance, and requests stop once it is exhausted. High-volume video ingestion and turnaround are being scoped with founding pilots while a dedicated bulk-video workflow is developed, which makes Kettio less suited to teams that need established bulk-video throughput.

The privacy policy describes encryption in transit and at rest, TLS/SSL, Firebase Authentication, security audits, access controls, and incident monitoring. It also says prompts and generated assets may be used to improve AI models by default; teams that do not want this use can opt out in Privacy Settings.

Pricing

Kettio has a free plan and two month-to-month paid plans. The shared monthly ad allowance matters: exhausting it stops rankings, including API requests.

Free keeps comparisons to two ads and limits users to four built-in personas, making it best for initial evaluation rather than broad audience testing. Starter raises the monthly allowance and adds profiles and generation credits, but does not include API access. Professional costs substantially more, but its fivefold increase over Starter's ranking allowance, unlimited profiles, API access, and priority support target teams with larger, more repeatable workflows.

Platforms

Kettio is available on web and through an API. Its stated ad-platform coverage includes TikTok, Instagram, Meta (Facebook), and general display. The back-test application names Meta and TikTok and allows applicants to enter other platforms such as Google.

Who it's for

Kettio is best for agencies and DTC teams producing a substantial volume of creative and looking to rank alternatives before spending on live distribution. Starter is a practical fit for teams that can work within 100 monthly rankings and do not need API keys; Professional is more appropriate when 500 rankings, unlimited profiles, API access, or priority support justify the higher monthly cost. It is a weaker fit for buyers seeking guaranteed performance predictions or high-volume video processing as a mature workflow.

Pros and cons

• Pros: Rankings include rationale, confidence, and suggested improvements, giving teams more to act on than a bare winner.
• Pros: Blind back-tests compare past-creative rankings with actual outcomes without showing outcome labels during ranking, a useful calibration option for qualifying high-volume teams.
• Pros: The free tier permits 20 monthly ad scores, and Starter adds 100 monthly rankings for 29.99 USD per month.
• Cons: Rankings are directional, not guarantees of CPA, ROAS, or purchases, so they cannot replace live campaign evidence.
• Cons: The free plan caps comparisons at two ads and offers only four pre-built personas; API access requires Professional.
• Cons: API and app usage share one monthly allowance, and ranking stops when it runs out; the bulk-video workflow is still being productionized.
• Cons: Prompts and generated assets may be used for model improvement by default, requiring an opt-out for teams that do not want that use.

Alternatives

Ad Creative Testing Tools is the category directory for comparing more options. Choose Marpipe instead if a free plan for exploring and previewing generative designs or launching dynamic product ads across platforms better matches the task. SaliencyLab is worth considering when a free, web-and-API tool for visual attention analysis matters more: its free plan includes 10 analyses per month, up to three per day, a five-KPI diagnostic and verdict, benchmark context, an attention timeline, and one teammate seat.

Consider Pencil if ad generation is the priority: its Core plan is 11.00 USD per month billed per month, billed annually, with 50 generations, one workspace, and chat support. AdTest.AI may suit teams comparing credit-based test pricing; its Creator plan is 30.00 USD per month for 20 credits, or 1.50 USD per test. Predis.ai is an alternative for teams seeking a broader social content and publishing package: its Core plan is 24.00 USD per month billed yearly at 288 USD, with 1,300 monthly credits, one brand, and publishing to 10 channels.

Spiral is another option for teams that want its Explore plan, priced at 175.00 USD per month, with two team members, 500 MCP credits, two app profiles, and one ad account. GetCrux is an alternative in the category. Motion may be a better fit for larger ad-spend operations: its Starter plan is 750.00 USD per month for up to $50k monthly ad spend, unlimited seats, and unlimited ad accounts.

Verdict

Kettio is a strong fit for agencies and DTC teams that produce enough creative to benefit from structured comparisons and want to calibrate rankings against past outcomes. Its combination of rationale, confidence, and blind back-testing is the clearest reason to choose it. Look elsewhere if you need guaranteed performance forecasts, bulk video at scale today, or API access without moving to the 139.00 USD per month Professional plan.
