Compare two versions of any text by word, character, line, or sentence. Highlight additions and deletions, view side-by-side or unified, ignore case or whitespace, and export the result — all in your browser.
Text Compare Tool
Paste two texts and see exactly what changed
Paste text on both sides and click Compare Text to see differences highlighted.
Advanced Text Comparison, Not Just Highlighting
Four diff granularities, two view modes, and filters that let you focus on the changes that actually matter.
Compare by word, character, line, or sentence depending on how precise you need to be.
Switch between an aligned two-column view and a single merged diff view instantly.
Ignore case, whitespace, or punctuation so cosmetic differences don't clutter the result.
See a similarity percentage plus character and word counts for both texts at a glance.
Load plain text files directly into either panel, then copy or download the diff result.
Comparison happens entirely in your browser — nothing is uploaded or stored.
How to Compare Two Texts
Paste or upload your content, pick a comparison mode, then review the highlighted result.
Paste Both Texts
Add the original version on the left and the changed version on the right, or upload files.

Words vs Characters vs Lines vs Sentences
Choose the right diff granularity depending on what you're checking.
| Mode | Purpose | Best For | Result |
|---|---|---|---|
| Words | Highlight changed words | Articles, emails, general writing | Word-level additions and deletions |
| Characters | Highlight exact character changes | Typos, IDs, short strings, codes | Character-level precision |
| Lines | Highlight changed lines | Code, config files, structured text | Line-by-line added or removed rows |
| Sentences | Highlight changed sentences | Essays, contracts, long-form content | Sentence-level rewrites |
Why Use a Text Compare Tool?
Catch every change without manually re-reading two documents side by side.
Automatic highlighting finds small changes that are easy to miss when reading manually.
Skip line-by-line manual proofreading and jump straight to what actually changed.
Line mode makes it easy to compare config files, snippets, or scripts before merging.
Get a percentage-based measure of how close two versions are, not just a gut feeling.
Ignore case and whitespace changes so you only see edits that actually matter.
Your text is never uploaded to a server — everything runs locally in your browser.
