FAQ
Is the diff algorithm accurate for code?
The underlying algorithm focuses on words; for code diffs that require line-based context or syntax-aware comparisons, specialized code diff tools (like git diff or IDE-based diffs) may be preferable. This tool is excellent for human-readable comparisons.
Can it handle large texts?
Yes, within the limits of your browser's memory. Very large documents may perform less fluidly on low-memory devices.
