FAQs

Is this a full document merge tool?: It highlights differences for review. It is not a collaborative Word-style track-changes editor.
Does formatting matter?: Comparison is text-based. Whitespace and line breaks can show up as differences.
Do you store the texts?: No. Comparison runs locally.
