Mitsuko

Mitsuko is a context-aware subtitle translation tool designed for creators, localization teams, and studios working with video content in over 100 languages. It focuses on accurately translating SRT, VTT, and ASS subtitle files while preserving tone, character voice, and genre-specific nuances, especially for anime, drama, and online video platforms. The primary purpose of Mitsuko is to streamline high-quality subtitle localization workflows, from single episodes to large batch projects.

The platform supports batch translation of multiple subtitle files, allowing users to process entire seasons or content libraries in one workflow. It leverages AI models tuned for dialogue-heavy media to handle slang, honorifics, cultural references, and timing constraints more reliably than simple machine translation. Mitsuko offers tools for reviewing, editing, and refining translations, enabling human translators to quickly adjust line-by-line output without leaving the interface. It also integrates with audio-to-subtitles workflows, making it possible to generate, translate, and finalize subtitles within a single pipeline.
