Most of the 5 million English Wikipedia articles have translations in at least one other language. Between different languages, though, the same Wiki article might vary in format, completeness, or bias. This is a quick-and-dirty tool for seeing what content you're missing in your native language without needing to understand the 288 languages that Wikipedia supports.
Look up an English Wikipedia article and select a language to compare it to. In green are Wiki
