About this tool
The PixelForge Text Diff Checker compares two blocks of text side by side and highlights all differences — additions, deletions, and changes — with colour coding. This is useful for comparing document versions, reviewing code changes without Git, spotting changes in contract or legal text, and verifying copy edits. The diff is performed line-by-line with character-level highlighting for changed lines.
