Translate Chinese straight off the screen
Scientific papers, industrial manuals, system panels, online stores. Chinese usually recognizes well — the errors come from two specific places.

How do you translate Chinese text on screen?
Select the area containing the text and let the tool recognize and translate it. Digital Chinese at normal font size is one of the most reliable cases for screen recognition — better than Japanese, because most modern material has neither furigana nor vertical writing.
The errors come from two places. The first is the absence of spaces between words: a sentence is a continuous run of characters, and recognition has to decide where each unit of meaning ends. When it splits wrongly, the translation changes subject without warning.
The second is confusion between Simplified and Traditional Chinese. They are two character sets for the same language, and several characters resemble each other enough to swap at small font sizes. Mainland China uses Simplified; Taiwan, Hong Kong and Macau use Traditional. If a translation comes out strange, that is a frequent suspect.
Where Chinese is easy and where it is not
Easy: scientific papers, technical documentation, websites, apps, system panels, frozen subtitles. Clean horizontal digital fonts recognize very well.
Harder: Traditional characters at small sizes, which carry more strokes than Simplified and lose definition sooner. Text inside online-store product images, usually compressed. And old scanned documents.
A particular case: Chinese technical manuals often mix English terms into the sentence. Recognition sometimes splits the English word in the wrong place — verify function and part names before using them.
How to reduce errors
Capture paragraph by paragraph
With no spaces between words, the larger the block, the more likely recognition splits one wrongly and drags the error through the rest.
Zoom in on Traditional text
Traditional characters carry more strokes. What is legible in Simplified may not be in Traditional at the same size.
Handle figures and tables separately
In papers, chart labels and table headers are pixels. Translate the figure on screen so labels stay in their original positions.
Verify numbers and units against the original
Machine translation sometimes reformats numbers and units. In technical documents, check the original before using a value.
Frequently asked questions
Do I need to know whether it is Simplified or Traditional?
Not to translate, but it helps explain a bad result. Mainland material is Simplified; Taiwan, Hong Kong and Macau are Traditional.
Does it work on a copy-protected Chinese paper?
Yes. Protection blocks selecting, but the text is still visible on screen — and what is visible can be recognized.
Why does the translation change subject mid-sentence?
Almost always a wrong word split, since Chinese uses no spaces. Capturing a smaller region usually corrects it.
Is it good enough to cite academically?
For triage and reading, yes. For literal quotation, no: cite from the original and have it checked by someone fluent, especially technical terminology.
