Multilingual Page Comparison Lab
Compare two localized page versions through separate technical and coverage checks, with native review kept explicit.
Use a URL, pasted HTML/text, or both. Pasted content takes precedence for that side.
Pasted content stays in this browser. Public URLs are fetched transiently through a bounded safety layer; bodies are not stored or logged.
This cannot prove translation accuracy, native fluency, cultural suitability, ranking or search performance.
