How many ads has Adblock Plus blocked on AI platforms?
Ads are arriving inside artificial intelligence (AI) assistants like ChatGPT and Copilot. Adblock Plus and AdBlock block them, the same as anywhere else. Here's a running count of how many we've stopped from reaching you, measured directly from filter activity, and what users think about ads in AI assistants. We'll add more platforms as they start showing ads.

Rolling 7-day window
Updated daily. We blocked ads since they first appeared and started counting those in late April (ChatGPT). Figures are approximate, drawn from anonymous, aggregated Adblock Plus and AdBlock filter activity. Never linked to you or your conversations.
By platform
Adblock Plus and AdBlock block ads across AI platforms. We track each one separately and only publish a count once we can attribute blocks cleanly to that platform.
What people say about AI ads

of US adults who use an ad blocker are concerned about AI chatbots using their conversation data to target them with ads, compared with 70% of surveyed users who don't block ads.
are very or extremely concerned about it.
This survey was conducted online within the United States by The Harris Poll on behalf of eyeo from May 19–21, 2026 among 2,066 US adults ages 18 and older. The sampling precision of Harris online polls is measured by using a Bayesian credible interval. For this study, the sample data is accurate to within ±2.7 percentage points using a 95% confidence level. This credible interval will be wider among subsets of the surveyed population of interest.

Every block counted here comes from a public, open-source filter rule. The lists are community-maintained, so anyone can inspect them, suggest changes, or build on them. The blocking is independent community work, not a private eyeo list.
How we count Methodology, refresh cadence & honest disclosure
What counts as an AI-platform ad
We count an ad when one of the public filter rules behind Adblock Plus and AdBlock identifies an ad on a known AI platform (for example, ChatGPT). The same rules that detect the ad are what hide it, so each detected ad represents one blocked from view. The counts are approximate by design (see below).
What we see, and what we don't
We attribute each detected ad to a platform using the page context reported by the browser's filtering application programming interface (API). An ad on an AI assistant's page is tagged to that platform and kept separate from general web browsing. The tag never includes uniform resource locator (URL) paths, prompts, or any of your content.
Refresh cadence
The counters refresh daily from anonymous, aggregated data, and the weekly figure reflects a rolling seven-day window. Because the data is aggregated and carries a small amount of privacy-preserving noise, the totals are deliberately approximate rather than exact. Between updates, the live count advances using a recent daily average, so it always tracks at or just behind the real figure, never ahead of it.
What we deliberately don't collect
We never log URLs, page contents, prompts, AI responses, or anything that could identify you. The counter reflects aggregate ad events, not a record of anyone's sessions. See our privacy policy.
HONEST DISCLOSURE Today, the ads on these platforms mostly appear as separate, labeled units, which our filters can catch. Ads woven directly into an AI's written answer (sponsored phrasing or product placements inside the response itself) are much harder to detect with filter-level data, and aren't fully captured here. Researchers have shown this kind of in-response advertising is technically possible and easy to miss, and retail assistants are already moving toward it, so we're working on ways to detect it. Until then, treat the numbers as a floor, not a ceiling.
