What is Text Diff Checker?

Text Diff Checker is a tool for comparing two texts and viewing the differences visually. It is useful when you want to inspect changes in code, documents, or configuration files.

You can switch between default mode and real-time mode, and the tool also shows statistics such as added lines, deleted lines, and change blocks. Processing stays inside the browser.

How to Use

1. Choose a comparison mode.
2. Enter the original and modified text.
3. In default mode, click Compare to show the result.
4. In real-time mode, review differences as you type.

Main Settings

Comparison Mode

• Default: useful when you want to enter both texts first and compare them in one step
• Real-time: useful when you want to see changes while editing

Display Options

You can toggle line numbers, gutter markers, highlighted changes, and line wrapping. These options help when reviewing longer text or code.

What You Can Review

• Added lines
• Deleted lines
• Change blocks
• Total lines in the original and modified text

These statistics appear above the diff result.

Use Cases

• Reviewing code changes
• Checking revised documents
• Comparing configuration files
• Tracking edits while rewriting text

Things to Keep in Mind

• In default mode, the diff result does not update until you click Compare
• In real-time mode, the result changes continuously with your input
• Processing happens in the browser, but it is still a good idea to review sensitive content before sharing it elsewhere
