LibreTranslate is a free and open-source machine translation API that is self-hosted, supports offline use, and is easy to set up.

It can be deployed locally for use. Starting from version 3.00, the video translation software supports its integration.

To use it, go to the software menu bar → Translation Settings → LibreTranslate API, fill in the API address and API key, and test for successful connection.

You can deploy it yourself and enter your locally deployed API URL, or use the official paid API address provided by LibreTranslate: https://libretranslate.com/translate.
