FAQ

      
How does the diff work?
A classic line-based longest-common-subsequence diff highlights added, removed, and unchanged lines entirely in your browser.

    
Is my text uploaded?
No. Comparison stays on your device.

    
Word-level diff?
This free view is line-oriented. Upgrade may add word-level highlighting later.

    
What is it good for?
Contract redlines, README edits, policy drafts, and support macros — common US knowledge-work tasks.

    
Upgrade?
Side-by-side sync scroll and exportable patch files when checkout is available.
