Paste an original and an updated version. The page highlights additions, deletions, and rewording, then explains what those edits often mean.
Paste text into both boxes to see a comparison.
The page will show additions, deletions, and rewording. It will also flag edits that may change meaning, tone, or obligation.
When a client sends a revised contract, a teacher returns a draft, or an employer updates a policy, the edits can be small but important. A missing “not”, a shorter deadline, or a softer apology can change what the text asks you to do. A plain text file does not show these changes clearly. This page does. It puts the two versions next to each other, marks the edits, and explains what they often mean in practice.
Many people search for a text diff tool only when something goes wrong. They sign a contract, miss a changed deadline, or submit an essay with a rewritten argument they never noticed. A simple comparison page helps you catch those edits earlier. It works best when you use it before you agree, submit, or forward the updated text.
Original: “The client may terminate the agreement at any time with notice.”
Updated: “The client may terminate the agreement only with 30 days’ notice.”
What matters: The word “only” narrows the right. The client cannot terminate instantly anymore. The page flags this as a high-risk edit because it limits flexibility.
Original: “The author argues that the policy failed.”
Updated: “The author implies that the policy failed.”
What matters: “Implies” softens the claim. The sentence now suggests the argument without stating it directly. Yellow highlighting helps you catch this kind of tone shift.
Original: “We hope to send the draft by Friday.”
Updated: “We will send the draft by Friday.”
What matters: “Hope to” becomes “will.” The promise gets stronger. That can matter if Friday passes and the draft is late.
Original: “Employees may work remotely when approved by their manager.”
Updated: “Employees may work remotely only when approved in writing by their manager.”
What matters: The update adds “in writing.” A verbal approval may no longer be enough. The page notes this because it adds a formal requirement.
| Color | What it marks | What to check first |
|---|---|---|
| Green | Words or sentences that were added | Do they add promises, limits, or tone that did not exist before? |
| Red | Words or sentences that were removed | Did they remove conditions, exceptions, or softened language? |
| Yellow | Rewording inside a similar sentence | Check for tone, scope, or obligation changes that hide inside small word swaps. |
| Orange | High-risk edits | Look for changes to “not”, “must”, “may”, “only”, “until”, deadlines, numbers, or parties. |
This page assumes the two texts are versions of the same document or message. It compares them word by word and sentence by sentence. It does not store your text on a server, and it does not replace professional review. It gives general notes about common editing patterns. It does not tell you whether a change is legal, binding, or safe to sign.
If the texts are very long, the page may slow down. In that case, compare one section at a time. If the texts are in different languages, the comparison still works, but intent notes will be less precise. Always double-check names, dates, amounts, and defined terms yourself.
