In their own words
AdTest.AI
AdTest.AI evaluates advertising creative before launch with AI scoring and optional audience research. Its engine scores ads across 13 dimensions and returns an overall effectiveness score, strengths, weaknesses and recommendations. It accepts images, video, carousels and messaging copy; AI Ad Studio can generate platform-ready variants from a brand URL and send them for scoring. Optional audience studies combine human ratings with AI scores in a Mixed Score, with audience reads taking 24–48 hours. Reports can be exported as branded multi-page PDFs, and audience results can be cross-tabulated and exported as CSV. Team workspaces support project sharing, role-based access, invitations and per-workspace billing. The seven-day trial requires no credit card and includes three AI test credits, but not API or MCP access. Paid plans include Creator at $30 a month and Starter at $50 a month; one-time audience studies start at 299.00 USD. Android and iPhone apps let existing users run tests and review reports, while purchases are made on the web. The service also offers a REST API and an official Claude MCP server for AI-only scoring.
Pencil
Pencil is a web-based creative marketing platform that uses AI to generate advertising copy, images, and video ads. Its workflow runs from briefing and generation through editing, approvals, publishing, and evaluation. The browser editor handles text, image, video, and HTML, with exports in GIF, MP4, HTML5, and static formats. Pencil says a single template can produce thousands of variations and be adapted across markets through localization or translation. Listed generally available ad integrations include Meta, TikTok Ads, LinkedIn Ads, Google Ads, YouTube, Display & Video 360, and Campaign Manager 360. Users can create six ads for free through a guided experience, but full platform access requires a paid plan. Core costs $11 a month billed annually and includes 50 generations per month and one workspace. Growth costs $44 a month billed annually, with 250 monthly generations and unlimited workspaces. Pro has custom pricing and unlimited generations. Pencil says its security controls are SOC 2 Type II audited and that customer data is not used to train its models.
