Here is a tool to annotate PO translation files using LibreTranslate, so that project maintainers can make sure the human-provided translations look plausible, even when they don't speak the target languages.

I developed this to be able to vet submitted translations for Pipe Viewer and other projects, to have some confidence that the submitter understood each string they translated in the context I'd intended, and to limit the likelihood of malicious mistranslations or vandalism.
It relies on LibreTranslate, but the project README outlines how to quickly install that on your local machine.
The project is hosted on the @Codeberg platform and was developed with their Translathon (https://codeberg.org/codeberg/translathon-2024) in mind.
