About Text Diff

The Text Diff tool is an online text comparison tool to identify differences between two texts. In office, development and document collaboration work, documents, codes and copies often have multiple versions. Manual word-by-word comparison for long texts is time-consuming and likely to miss minor changes. This browser-based tool requires no installation. Paste two texts and it will compare line by line and character by character automatically. New content, deleted content and modified content are marked with different colors to display all differences clearly. It supports ultra-long texts, code snippets and mixed Chinese and English content while retaining original layout. Users can switch between single-column and double-column views, and check the number of different lines and characters. It quickly locates modifications for code files, contracts, copies and configuration texts.

How Text Diff works

Version comparison is a frequent demand in daily work, but manual text comparison has obvious drawbacks. Comparing long texts with hundreds of lines manually takes a lot of time, and people tend to miss minor changes like punctuation and words due to fatigue, which leads to work errors.

Traditional text comparison relies on editor plugins which need installation and configuration and bring frequent tool switching. Built-in comparison functions of online document platforms only support their own file formats and cannot handle plain text and code. Command-line diff tools have a high learning threshold and are only accessible to a small number of professionals.
