Expert Tips for Text Comparison
For Legal Documents
Use character-level comparison with punctuation sensitivity turned on. Legal documents often contain crucial punctuation that changes meaning.
For Programming Code
Turn off whitespace sensitivity to ignore indentation changes but keep case sensitivity on for variable and function names.
For Academic Papers
Use word-level comparison with case sensitivity off to focus on concept and content changes rather than stylistic differences.
For Website Content
Enable the "Ignore HTML Tags" option when comparing web content to focus on the visible text rather than markup changes.
