English ↔ Chinese translation

Equalang uses AI to capture the context and find natural cultural equivalents for idioms in both languages. Because figurative meanings can be nuanced, someone should review important texts.

Yes, the Equalang browser extension translates web pages and video subtitles while displaying the original text beside the translation. For critical content, it is best to have a person check the AI translation.

Formatting is kept as far as possible: PDF translations keep columns, headers and footers, captions, and paragraph levels, bold text stays bold, links in the table of contents and cross-references still work, and sentences split across page breaks are rejoined before translating; Word, PowerPoint, and EPUB files keep their formatting as far as possible, and Excel numbers and formulas are left as they are. Font sizes and line breaks may adjust when translation length changes, and complex layouts, scanned PDFs, heavy watermarks, or language-dependent Excel text formulas should still be checked against the original in the side-by-side workspace.

New accounts receive 200 credits to try it out, and purchased credits never expire and are shared across the website and extensions (the smallest pack is $10 for 10,000 credits). Text translation is billed by length at 10 credits per 1,000 tokens, where 1,000 tokens is roughly 750 English words or 1,000 Chinese, Japanese, Korean, Thai, or Hindi characters.

Uploaded files and translated results are kept for 14 days so you can view and download them, then removed from access, and you can request deletion of your submitted content and account data at any time. Equalang does not sell personal data or use your submitted or translated content to train AI models.
