Text Diff
Compare two texts and highlight differences
What is Text Diff?
Text Diff compares two blocks of text side-by-side and highlights additions, deletions, and modifications — making changes easy to spot at a glance.
When to use this tool
- Comparing two versions of a document or code snippet
- Reviewing changes before and after editing
- Identifying differences in configuration files
- Verifying text transformations or formatting changes
How it works
Applies a diff algorithm (typically Myers or patience diff) to find the minimum edit distance between the two inputs. Changed lines are highlighted: additions in green, deletions in red, and unchanged lines in neutral.
