About
JuxtaText is a Mac app for comparing text without any setup. You can open a file, drag it in, or paste what you have, and each piece is collected in a sidebar so you can move it to either side of a comparison whenever you want another point of view.
For merging, JuxtaText offers a three-pane tool. Open any side-by-side comparison, choose the parts you want, and edit the result directly while keeping all three versions visible. Line-level changes stay highlighted as you work, and word differences update as you type.
JuxtaText is free to open and compare. For code diffing and merge-conflict resolution, the website points to its sibling app, JuxtaCode, which adds Git support.
What's new
All release notes- Improved diffing algorithm: better recognition when two bodies of text mainly differ by their line breaks. For example, if [A] has a long paragraph all on one line and [B] has the same content split over multiple lines to maintain a maximum column width, then both passages will be grouped as "modified ≠" and their newline differences highlighted. - Improved diff UI: extra connecting lines now appear in diff dividers when there are a few scattered word differences that might be hard to spot within a large modified segment. In these cases, they'll help to point out where they are and which lines they match up on. - Performance improvements when generating large diffs. - Fixes an occasional stack overflow crash when generating diffs. - You can edit a text clipping's title by selecting it in the sidebar and pressing enter. - Fixed a bug that caused scrolling to break when both sides of a diff were identical. - Navigation toolbar buttons (up and down arrows) now become disabled when there are no segments to navigate in a diff.
