Lingtrain Studio is a web application for aligning texts in two languages to create parallel corpora and generate bilingual books. It features a Vue.js 2.x frontend with Vuetify and a Flask backend that integrates machine learning models (such as LaBSE and sentence-transformers) for automatic sentence alignment. Users can upload texts, split them into sentences, align them using batch processing, manually correct alignments, and export the results in various formats (HTML, TMX, PDF). The application is Dockerized for ease of deployment and includes tools for model fine-tuning and PDF generation from aligned XML.
