You can use machine translation through the Intento plugin for Trados in two modes:
1) Pre-translation of the whole project while preparing it for translation.
2) Pre-translation of each segment separately while working on translation.
In both cases, you will see the "AT" label for "automated translation" between source and target fields when machine translation is applied.
If you hover the mouse, you will see the name of the provider used via the Intento plugin.
