Poedit is a gettext translation (.po file) editor for Unix, Windows, and OS X. It aims to provide translators with a simple, easy-to-use user interface with all the essential tools, such as spellchecker or translation memory. It can also be used to manage translations for small projects.
Poedit comes with a builtin translation memory to help you translate faster. It remembers your past translations and uses them to make suggestions for similar texts. Over time, it learns enough to fill in frequently used strings for you.
Poedit has dedicated support for WordPress themes and plugins, allowing you to focus on the translation instead of worrying about the technical details.
