Languine is a tool that leverages artificial intelligence to assist developers in application internationalization. It streamlines the multilingual translation process through a command-line interface (CLI), allowing developers to select source and target languages while automatically generating language files. With globalization, more applications need to support multiple languages, but traditional translation processes can be time-consuming and costly. Languine integrates advanced models from OpenAI, such as GPT-4, offering a fast, efficient, and cost-effective solution. Currently, Languine offers a free trial, and specific pricing and positioning can be found on its official website.
