The Parallel Passages tool helps translators ensure they have been consistent in their translation of parallel passages. Paratext has a vast list of parallel passages to help in checking.
Exact matches are hightlighted in green, similar text is highlighted in yellow.
Paratext intelligently compares your translation text, highlighting matching text in green.
Paratext also highlights matching text in other translations, to help you see what is parallel.
When parallel passages are translated appropriately parallel, mark them as finished.
