WebTranslateIt was inspired by the founder Edouard's experience in developing a web-based translation tool for the music platform Last.fm. Unable to find a suitable translation solution online, he took the initiative to design one himself. In WebTranslateIt, a language or locale is characterized by various parameters including the user’s language, country, and any specific variant preferences desired in their interface. Typically, a language includes both a linguistic identifier and a regional identifier, exemplified by combining English with the United States to form “en-US.” Language files are organized within the File Manager, where adding a new language results in WebTranslateIt automatically generating target files for each master file present. Additionally, when a new master file is introduced, target files are seamlessly created and assigned to the languages already in use, ensuring a streamlined translation process for users. This functionality not only enhances user experience but also simplifies the management of multilingual content across platforms.
