Not just translating text,
but restoring the soul of your documents
Absolute timeline security
This is the baseline. We translate text only, strictly safeguarding SRT timecodes (00:00:00,000) to ensure subtitles remain perfectly synchronized with both visuals and audio.
Conversational context translation
Say goodbye to awkward literal translations. AI models (such as Claude) understand colloquial expressions and context, delivering translations that sound as natural as a native speaker’s conversation.
Intelligent line length optimization
To ensure optimal readability, the system automatically detects and adjusts translated line lengths. This prevents single lines from becoming excessively long and obscuring the screen, resulting in a more comfortable reading experience.
Batch Series Processing
Supports uploading dozens of SRT files simultaneously. Parallel processing delivers subtitle translations for entire seasons within minutes.
Bilingual Subtitle Generation
Select 'Bilingual Mode' to generate SRT files containing both the original text and translations—ideal for language learning or reference viewing.
Custom Terminology Database
Upload lists of character names, place names, or proper nouns to ensure consistent terminology across entire series or video collections.
Why does format matter?
- Precise formatting is the hallmark of professionalism.
- Reduce secondary formatting time.
- Ensure accurate and precise information delivery.
