A Simple Guide to Comparing Texts for Differences
Have you ever had two versions of a document, email, or block of code and needed to know exactly what changed? Reading through line by line is slow, tedious, and prone to error. Thankfully, there's a much better way.
Our online Text Compare tool is designed to instantly highlight the differences between two pieces of text. Here’s how to use it in just a few simple steps.

Step 1: Open the Text Compare Tool
First, navigate to our free Online Text Compare tool. You'll see a clean interface with two main panels side-by-side, labeled "Original Text" and "New Text".
Step 2: Paste Your Texts
Next, copy the first version of your text (the "original" or "before" version) and paste it into the left panel.
Then, copy the second version of your text (the "new" or "after" version) and paste it into the right panel.
You can also use the "Upload Left" and "Upload Right" buttons to load content directly from text files on your computer.

Step 3: See the Differences Instantly
The moment you paste the second piece of text, the tool automatically compares them and highlights the differences.
- Red highlighting on the left shows content that was removed.
- Green highlighting on the right shows content that was added.
You can easily switch between a "Side-by-Side" view and an "Inline" view to see the changes in the format that works best for you.

That's It!
In just a few seconds, you've accurately identified every change, addition, and deletion between your two texts. No more manual proofreading or guesswork. Whether you're a student, a writer, or a developer, our Text Compare tool can save you valuable time and effort.
