Semantic similarity
Compare element text with a meaning you describe, instead of maintaining a list of exact phrases.
Experimental, open-source Chrome extension
Blur page content by what it means
AI AdBlocker combines CSS selectors with semantic, prompt, and vision checks. You decide what a rule should recognize; matching elements are blurred on the page.
Requires desktop Chrome 149 or later.
Three ways to match
Go beyond a static selector when the page is ambiguous
Prompt classification
Ask a language model whether selected page text matches a plain-language rule.
Visual analysis
Evaluate a screenshot of a matched element when appearance matters more than its text.
A rule you can test
Start with the page, then add meaning
- 1. Select elements. Use a CSS selector to narrow the candidates.
- 2. Describe the match. Add an embedding, prompt, or vision condition.
- 3. Test and refine. Preview the result before relying on the rule.

Local and cloud model options
Local options
Use Chrome’s built-in AI where available, or connect LM Studio on your computer. Availability and model support depend on your setup.
Cloud options
Choose OpenAI or OpenRouter with your own API key. Selected text or screenshots are sent directly to that provider for analysis and may incur provider charges.

AI results vary by page, model, and rule. This tool blurs matched elements; it does not block network requests or guarantee that every advertisement or unwanted item will be recognized. Cloud models require an account, API key, and may cost money.
