Meta Ad Library vs Metistic in 2026: Public Meta creative vs tracked ChatGPT ads

Meta Ad Library is a public research surface for ads currently running across Meta technologies. A strategist can set a location and category, search an advertiser or keyword, and inspect the creative Meta has made public. That makes it the sensible first source for checking a live Facebook or Instagram example before relying on a third-party database. It is an observation tool, however, not access to the advertiser’s account. A visible ad does not reveal conversion results, revenue, bids, targeting strategy, or the full logic behind a media plan.

The word library can overpromise unless the retention rules are kept in view. Meta says it keeps social-issue, election, and political ads for seven years, ads delivered in the EU for one year, and specified UK ad history for one year. Its separate Report supports exploration and downloads for political and issue ads, while the published API has defined political, issue, UK, and EU scope. A stopped ordinary commercial campaign is not automatically a permanent global record. That makes the product strong for first-party verification, not for reconstructing every campaign a competitor has ever run.

Meta also offers a branded-content search for disclosed paid partnerships across Facebook and Instagram content. Those routes are useful for compliance, research, and creative reference, but they do not create a team swipe file, alerts, or account-management workflow. There is no subscription price in the reviewed profile. Use it when the evidence needed is public Meta creative or its stated transparency records; move saved examples into a separate operating workflow if they need annotation, collaboration, or later retrieval.

Metistic is built for a newer and much narrower paid-ad question: what paid placements were observed when the product checked a selected set of commercial ChatGPT prompts in a selected market. A team supplies its site, chooses a market, and selects prompts. Daily checks then record whether the team’s brand appeared, which advertisers appeared, the recorded creative and destination, and prompts where a competitor appeared while the customer did not. It deliberately separates that latter ad gap from a result where no ad was seen, because those findings call for different follow-up work.

The measurement language is important. Ad presence is the share of completed checks that contained a brand’s ad, and share of voice is a share of recorded ad appearances within the chosen prompts, market, and period. Metistic displays completed-check counts alongside those percentages. Its findings are useful scoped evidence, not a census of all users, ChatGPT impressions, advertiser spend, bids, targeting settings, or campaign delivery. Paid tiers can also record competitor product ads and the displayed price, attached to the prompt, market, and date, which helps an ecommerce team review a concrete observed example.

Free supports 10 prompts in one of 53 markets and 30 days of history. Starter costs $79 per month for 50 prompts in one market, full history, competitor product prices, alerts through email, Slack, and webhooks, plus CSV exports. Growth costs $299 per month for 200 prompts across supported markets and adds scheduled PDF reports. That makes Metistic a specialist measurement layer for a paid-AI review, not a Meta creative archive or an ad-buying console.
