Changing the translation engine

You can change the translation engine for a specific translation language. We automatically recommend one of the engines, but you can test and change it as you wish.

If you want us to integrate a new translation engine that better supports your use case, please contact us and we'll be happy to consider it.

Custom dictionaries

Most translation engines support custom dictionaries. You can use this feature to tweak the translation of any pair of languages. Useful for specific words of phrases that are not correctly translated by the machine translation engine, especially proper nouns (like brands, e.g. Shell).
