Synapsoft adds AI translation to Synap Document Viewer
The update translates Korean, English, Japanese and Simplified Chinese while preserving page count and layout, and adds masking for sensitive data.
Synapsoft released an update to its Synap Document Viewer on November 11, 2026, adding AI document translation and a sensitive-information masking feature, according to digitaltoday.co.kr.
The translation function supports Korean, English, Japanese and Simplified Chinese. It keeps the original page count and layout and translates only the text. The viewer handles PDF, HWP, HWPX, Word, PowerPoint and Excel files.
Customers can use their own LLM as the translation engine in addition to external AI services. Documents saved as PDF after translation carry a watermark indicating they were AI-translated.
The new masking feature hides designated patterns when documents are converted to images or PDF, and Markdown (MD) files can now be viewed directly without downloading.
Twice-yearly updates
Synapsoft issues regular viewer updates for all customer companies twice a year, and more than half of the newly added features were developed from customer requests.
