About this tool
The text comparison tool creates a clear line-by-line diff for two text blocks. Removed lines start with a minus sign, added lines start with a plus sign, and matching context stays visible. Use it to review edited copy, compare configuration snippets, check generated output, or find a small change in a list. Strict line and calculation limits prevent very large comparisons from using too much memory or processing time.
