How to compare text files
Paste your original text on the left and the revised version on the right. Every inserted word is highlighted in green, every removed word in red, so you can scan a large document for changes in seconds.
TextCompare also supports uploading .txt, .docx, and code files directly, with automatic language detection for syntax highlighting.
Whether you are checking the differences between two drafts of an essay, comparing contract revisions, or diffing a config file, every change is tracked at the word level so nothing slips through.
