ASS Subtitle Translator

About

This ASS subtitle translator utilizes advanced AI models, including ChatGPT and Gemini, to translate Advanced Substation Alpha files while fully preserving timing, scene structure, and complex styling. The system focuses solely on the dialogue text for translation, leaving timecodes, layers, positioning, colors, fonts, and karaoke effects untouched, ensuring that the translated track looks and functions exactly like the original.

Simply upload an ASS file, select the target language, and start the translation with a single click; large subtitle files containing thousands of lines are processed in seconds, making it ideal for movies, series, anime, and heavily formatted fansubs. Once the task is complete, you can export subtitles in ASS format as well as TXT, SRT, or VTT formats to accommodate various editing and delivery workflows.

Core benefits include frame-accurate timing preservation, advanced formatting retention (styles, colors, positioning, karaoke tags), support for over 130 languages, and the ability to manage very large, stylized files without compromising typesetting. New users receive trial credits to experience AI subtitle translation, with premium plans available for studios, localization teams, and high-volume creators. Subtitle data is processed on secure servers based in the US and deleted within a day, with only lightweight translation history stored locally in your browser to help you keep track of recent projects
