There are 2 functions to help your read and understand texts on the Internet or on Word documents, auto translator and page translator. Those are more sophisticated versions than the one we use in our free dictionary.
Auto translator is used when you want to read japanese texts and only need help with a few words now and then. It stays on top of your desktop all the time and activates when you copy a text to the clipboard. You can save the found entry to your study list.
For larger texts you can use the page translator. Both translators can be used for any number of japanese characters but it is easier to read large tests on the page translator. Other than that they work the same.
