This plugin allows you to use DeepL translation API to translate posts ( and pages ) right from your WordPress Admin. 
Adds a translate button to the edit post page. 
Shows current and remaining API usage.
This plugin requires an active DeepL API subscription with access to the API. 
Please note that DeepL User or Teams plans do NOT include API access. 
You have to get a <a href="https://www.deepl.com/fr/pro/change-plan#developer" rel="nofollow ugc">“DeepL Developer” plan</a> (both ‘DeepL API Free’ and ‘DeepL API Pro’ work with this plugin)
Want to translate Products, meta fields, or translate in batches ? 
Get the <a href="https://solutions.fluenx.com/en/produit/batch-deepl-translation-for-wordpress-posts/" rel="nofollow ugc">DeepL Pro API plugin</a>
Please note : the free and the premium version works the same relative to content editors ( Elementor, Blocks, etc.). You’re free to test this plugin on your website to see if your specific configuration works well with the plugin. We cannot guarantee that all content editors work perfectly with the DeepL API so please test this plugin before buying the premium (you’ll need the premium only if you need extended features like meta translations and batch translations)

DeepL API translation plugin

I have tested the plugin about 1-2 years ago and a lot has changed since then: By now it works absolutely stable for the translations of our content, which are created with the block editor. You can set the languages beforehand and also correct the translations manually. We use this plugin now on several websites in combination with WPML. 

Important: You need a DeepL developer API (the personal DeepL license does not work) and you should have a close look at the error log if something does not work. A setup wizard would be recommendable here!

Cyr-To-Lat

Использую давно этот плагин, на всех своих и клиентских сайтах. До этого использовал плагин Антона Скоробогатова. Можно настроить под себя, но я сейчас использую по умолчанию настройки. Клиентам нравится еще и то, что можно почти заниматься переводом, а просто транслитером))
