How does the Text Compare tool work?
Our text compare tool analyzes two pieces of text side-by-side or inline to detect additions, deletions, and updates. It runs entirely client-side, using the Monaco editor's diff engine.
Is my data secure when using the diff checker?
Absolutely. All processing and comparison are done locally inside your web browser. No text is uploaded or stored on any server, ensuring complete confidentiality of your sensitive files.
Can I toggle between side-by-side and inline diffs?
Yes, you can click the 'Inline View' / 'Side-by-Side' button in the toolbar to change the comparison visualization layout at any time.
