About Text Comparer
Text Comparer is a browser tool for comparing two pieces of text side by side. It helps you see what changed between an original version and a newer version.

Who it is for
For writers, administrators and reviewers checking wording between two drafts. It is useful when you need to identify a changed date, amount or sentence without rereading both versions line by line.
What you can use Text Comparer for
Text Comparer can be useful for checking drafts, policies, emails, letters, website text, copied notes, contract wording, support replies, and any document where small text changes matter.
Features
- Original and revised text entered side by side.
- Inline highlighting for changed words and characters.
- Colour-coded results: red for wording changes, blue for added or removed lines and spacing changes, brown for multiple changed areas, and yellow for the currently selected difference.
- Difference count with Previous difference and Next difference navigation.

- An Identical indicator when both versions match.

Tips for using Text Comparer
Keep the original consistently on the left and the revision on the right. Compare one section at a time for long documents. If you use Ignore options, remember that a match under those settings may still contain differences you chose to ignore.
Important limitations
The comparison concerns the text you paste, rather than the complete formatting or meaning of the original documents. A highlighted change still needs human review to decide whether it is correct.
Data and privacy
Review the tool instructions before entering or uploading information. Do not include passwords, payment details, private keys, or other highly sensitive data unless you understand how it is handled. Check the result before downloading or sharing it.
