Pantheon.ad is a Meta ads research tool for coaches, consultants, course creators and B2B service businesses. It searches the Meta Ad Library for long-running ads, since an ad that survives for months is usually paying for itself. The Starter public library covers only pages with ads live 30+ days. It also identifies the persuasion mechanisms in the copy, and offers Ad Copilot and Competitor Spy.
Pricing is Starter at 29 EUR per month (research, no AI analyses), Pro at 59 EUR per month (adds Radar, the agent and analyses) and Scale at 259 EUR per month. Pro and Scale include a Claude MCP connection. There is a 5-day free trial with no card, a 30-day guarantee, and annual billing with 2 months free. It is a web tool, and the public library grows one market at a time.
Ad libraries show you what is running, not what is working. Pantheon.ad starts from your offer, looks at the advertisers that matter for it, and uses one signal anyone can check: how long an ad has stayed live.
