With the Qt 6.8 LTS release, Qt's framework documentation at https://doc.qt.io/qt-6/ is now machine-translated to five additional languages:
Chinese (Simplified), Japanese, Korean, German, and French.
You can select a language from a drop-down list under the globe 🌐 icon:

These are created using the DeepL translation service. As they are machine-translated, there can be a number of inaccuracies or incorrectly-translated terminology especially in the context of API reference documentation. While it may not be possible to ensure best possible translation of a single sentence to all target languages, we will continue to improve the process.
If you spot any issues that affect all target languages, let us know! Either use the feedback link on the documentation site, or create a bug report (in English).
We hope that many people will find these translations useful!
very cool, thank you!!!
I look forward to introducing AI into Qt Lingust and providing reference translations.
