Would it be possible to add a translate option to posts?
Maybe DeepL would be an alternative to Google Translate. They offer the API to developers starting from €5 per month.
Here's the github issue with the specs on this https://github.com/OpenbookOrg/openbook-api/issues/267

That's a good idea, but I guess the translation would need to be using an API like google translate, which could be quite expensive. Just long press to copy and then paste it to google translate or other translators
