Text Diff / Compare

About Text Diff / Compare

Compare two blocks of text side by side with color-coded highlighting of additions, deletions, and unchanged lines. Paste two versions of a document, contract, code file, or email to spot exactly what changed between them — no signup, no upload, and no software to install. The comparison runs entirely in your browser, so confidential drafts and source code never leave your device.

How To Use

  1. Paste your original text into the left input and the revised text into the right input.
  2. Run the comparison. Added lines are highlighted in green, removed lines in red, and unchanged lines stay plain so every edit is visible at a glance.
  3. Copy the highlighted result, or tweak either input and compare again to review further revisions.

Example

Input: Two versions of a contract clause, or a before/after draft of a code function.

Output: A side-by-side diff with every inserted and deleted line color-coded, ready to copy or screenshot.

Who Uses Text Diff / Compare

  • Writers, editors, and developers comparing document or code revisions side-by-side with clear visual diffs.
  • Teams reviewing contracts, PRs, or drafts where privacy matters and nothing can be uploaded.
  • Anyone needing a fast private diff tool without installing desktop software or sharing sensitive content.

Frequently Asked Questions

How does the text comparison work?

Paste your original text on the left and the revised text on the right. The tool breaks both into lines and words, then highlights additions in green, deletions in red, and matching lines in their normal color so you can see every change at a glance.

Can I compare code with it?

Yes. Text Compare works on any plain text, including source code, JSON, CSV, configuration files, and markdown. Because it compares line by line and word by word, it is well suited to reviewing small edits and pull-request-style changes.

Is my text uploaded to a server?

No. The entire comparison runs locally in your browser. Nothing you paste is ever transmitted or stored, which makes the tool safe for confidential contracts, legal drafts, and private source code.

What is the difference between a diff and a text comparison?

They describe the same idea. A "diff" is the technical term (from Unix tools like diff) for the set of changes between two texts. A "text comparison" is the same process viewed side by side. This tool shows both at once: a highlighted inline diff and a clear before/after view.
