Frequently Asked Questions
A text merge tool combines changes from two different versions of a text against an original. It automatically merges non-conflicting changes and lets you manually resolve conflicts where both versions changed the same lines.
When both Version A and Version B modify the same lines differently, a conflict is shown. You can choose to keep the changes from Version A or Version B for each conflict. Non-conflicting changes are merged automatically.
3-way merge compares two modified versions against a common original. This allows the tool to determine which side made changes and auto-merge when only one side modified a line, flagging conflicts only when both sides changed the same content.
