ASS Subtitle Translator

This ASS subtitle translator employs advanced AI models such as ChatGPT and Gemini to translate Advanced Substation Alpha files while fully preserving timing, scene structure and complex styling. The system isolates only the dialogue text for translation, leaving timecodes, layers, positioning, colours, fonts and karaoke effects untouched so the translated track looks and behaves exactly like the original.

Upload an ASS file, choose the target language and start translation with a single click; large subtitle files with thousands of lines are processed in seconds, making it suitable for films, series, anime and heavily typeset fansubs. Once the job is completed, you can export subtitles in ASS as well as TXT, SRT or VTT formats to accommodate different editing and delivery workflows.

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