Compare an original text with a revised version and inspect word-level additions and deletions in one result. Use it to review a draft, check a changed sentence or spot edits in a short plain-text snippet.
lightbulb When to use this tool
- check_circle Review wording changes between two versions of an email, article or product description.
- check_circle Check that a manual find-and-replace changed the intended words.
- check_circle Compare small configuration or source snippets when a visual word diff is enough.
Inputs and results
Input: Original and modified text pasted into the two input areas.
Output: A combined comparison that highlights inserted and deleted text.
Why use our tool?
Review changes together
Added and removed text appears in a single comparison view.
Try a clear before-and-after example
A short before-and-after example makes the changes easy to inspect.
Compare pasted text directly
No account or document upload is needed for pasted text comparison.
How it works
Paste the earlier text into Original and the revised text into Modified.
Click Compare to generate the result.
Read highlighted deletions as text removed from the original and additions as text introduced in the revision.
If the result is too dense, compare one paragraph or section at a time.
Review context manually; a highlighted edit can still preserve the meaning, and unchanged wording does not prove factual correctness.
Examples
science Review a single word change
Original: The red car. Modified: The blue car. The result marks red as removed and blue as added, leaving the surrounding words unchanged.
science Check an added condition
Original: Delivery is free. Modified: Delivery is free on orders over $50. Review the added condition in context; the tool identifies wording changes rather than deciding whether the policy is correct.
Limitations
This is a word-based text diff, not semantic analysis or a plagiarism detector. It compares pasted text rather than PDF, Word or rich-text formatting. Whitespace and tokenization can affect the result. It has no option to ignore case or whitespace; use short, relevant sections when long documents are hard to review.
