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.

Text Compare — 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.

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.

What is text compare?

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 it

  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.

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

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