During December 2025, Matheus Fongaro contributed to the TriliumNext/Trilium repository by implementing Brazilian Portuguese localization, focusing on expanding accessibility for Portuguese-speaking users. He established a translation workflow using Weblate and delivered an initial PT-BR update, translating 3.2% of the application’s 152 strings in JSON format. His work laid the foundation for broader internationalization by integrating localization processes and documenting translation resources. Although no major bugs were addressed during this period, Matheus’s efforts centered on enhancing user onboarding and market reach through targeted translation and localization skills, providing a starting point for future expansion of the application’s language support.
