Tool overview
Tencent Interactive Translation (TranSmart) is more than a simple machine translation endpoint; it is a free translation platform combining neural translation, interactive term revision, and document formatting preservation. Developed by Tencent AI Lab, it supports over ten languages (including Chinese, English, Japanese, Korean, French, German) and offers text translation, full-page webpage translation, document translation for PDF/Word/PPT/Excel, and browser extension with inline translation. Its standout feature is “interaction”: users can click to edit terms in the output, and the system provides real-time suggestions, helping correct domain-specific terminology in a Grammarly-like fashion, but focused on translation output.
The tool is completely free—no subscription or paywalled features according to current evidence, which all confirms the absence of any charging plan at this stage. Registration is required via email or WeChat. The web interface has no OS restrictions, and browser extensions support Chrome, Edge, Firefox, etc.
