Veridiff uses a token-based diff algorithm that breaks your text into meaningful units (words, characters, numbers) and finds the longest common subsequences. This gives you precise, character-level change detection.
Your data never leaves your browser. Veridiff processes everything locally using JavaScript. No files are uploaded, stored, or transmitted to any server. Your documents remain 100% private.
Veridiff supports Word documents (.docx), PDF files (.pdf), Excel spreadsheets (.xlsx, .xls), and plain text files (.txt). You can also paste text directly into the editor.
When enabled, Veridiff normalizes special whitespace characters (full-width spaces, tabs, zero-width characters) so that formatting differences don't appear as changes. This helps you focus on actual content modifications.
