# Text Compare

> Compare two pieces of text and see the differences highlighted word by word. A side-by-side diff that is easy to read, runs in your browser, and never uploads anything.

Categories: text-tools
Privacy: Both texts are compared entirely in your browser. Nothing is sent to a server. The output stays in the page; closing the tab discards it.

## About

A word-level diff with a clean side-by-side view. The text on the left is the "before" version; the right is "after". Words that exist in only one version are highlighted; unchanged text stays neutral so your eye can scan for the actual changes.

Unlike the line-level text-diff tool, this one never cuts the text into arbitrary lines — it preserves the full text and just flags what changed at the word level. Better for prose; for code, the line-level text-diff tool is the right fit.

## How to use

1. **Paste the "before" text** — On the left side. The full text, no need to trim.
2. **Paste the "after" text** — On the right side. The diff appears immediately below as you type.
3. **Read the diff** — Added words are highlighted on the right; removed words are highlighted on the left. Unchanged text is in the standard body color.

## Examples

### Email reword

Before and after versions of the same email.

Input:

```
A: "Hi Alex, please send the file." / B: "Hi Alex, can you send the file when you get a chance?"
```

Output:

```
"please send the file" → "can you send the file when you get a chance?"
```

## FAQ

### How is this different from the text-diff tool?

Text-diff is line-by-line — best for code, structured text, and seeing which line changed. Text-compare is word-by-word and inline — best for prose, where you want to see the actual word changes without the text being broken into lines.

### Are my texts uploaded?

No. Both texts are compared in your browser. The diff is computed on your device and never leaves it.

### Is there a size limit?

Yes, but a generous one. Texts that would require more than 4 million cell comparisons bail with a clear error — this is enough for tens of thousands of words on each side.
