FAQ

How does the text comparison work?

Our tool uses a line-by-line diff algorithm to compare the two texts. It highlights lines that were added, removed, or changed, making it easy to spot differences.

Is my text stored or shared?

No. All processing happens in your browser. Your text is never sent to our servers, so your content remains private and secure.

Can I compare code with this tool?

Yes, you can compare any text, including source code. The diff highlighting works for code as well, helping developers review changes quickly.

Is there a limit to the text length?

There is no strict limit, but extremely large texts may slow down the comparison. For best performance, keep each text under a few thousand lines.
