FAQ

What content is the text comparison tool suitable for?

Suitable for comparing copy, code, JSON, configuration files, SQL, Markdown, and other plain text content to quickly find added, deleted, and modified positions.

Can it be used to check where two code segments differ?

Yes. For before-and-after version code, interface configuration, script modifications, and copy-paste difference troubleshooting, this type of tool is very efficient.

Why is highlighting differences more reliable than manual visual checking?

Because the tool directly marks specific change positions, reducing missed spaces, punctuation, variable names, and subtle line content differences.

Is it suitable for copy proofreading and version checking?

Very suitable. Pre-launch copy checking, contract text verification, configuration change confirmation, and collaborative review are all common use cases.
