For whom?
LSDE is designed for developers who want to retain full control over their creations, while fully leveraging modern technologies. In this context, LLMs act as copilots, but you remain the pilot of your project. Integrating i18n into your project is an effective strategy to boost your international sales and improve UX.
WEB developer
This is for web developers who are looking to efficiently manage i18n with their HTML markup and to get a better visualization of their layout rendering.
video game developer
For video game developers who wish to sell their creations globally. For those who work on proprietary game engines with custom needs. For creators who want to enrich the narrative atmosphere of their universe. For those who desire to maintain total control over their story and narrative quality.
software developer
This is for software developers who want to delegate some complexity to focus on their code. It's for developers who want to centralize internationalization (i18n) and reduce their mental load by delegating translation and redundancy to the LLM. It's for developers who desire a close connection with their project and writing.
