There are a number of other tools that can be useful in various ways for translation of WordPress projects, some of them are listed below. Just keep in mind that if you translate outside of our main platform then after you finish your translation, you will need to go to translate.wordpress.org and import the relevant gettext files, as the language packages are built from there.
Also note that a translation editor must perform translation review directly in translate.wordpress.org and never in external systems. The reason for this is in order to correctly preserve translation credit for the user who submitted the translation.
