Text Compare
Paste two pieces of text and instantly see the differences highlighted line by line. Perfect for comparing documents, code, and drafts.
Paste text in both panels above to see the diff
Differences are highlighted directly in the text as you type
How It Works
Paste your original text into the left panel and the changed text into the right panel. Differences are highlighted directly inside the text panels as you type — changed lines get a background colour, and the exact changed words within those lines are highlighted more intensely.
Reading the highlights:
- Red highlight (left) — lines/words removed from the original
- Green highlight (right) — lines/words added in the changed text
- The diff panel below also shows the full line-by-line breakdown
- Use Ignore Case to treat uppercase and lowercase as equal
- Use Ignore Whitespace to skip leading/trailing space differences
- Use Swap to reverse the comparison direction instantly
Inline Highlights
Changed words are highlighted directly inside the input panels — red for removed, green for added — so you see changes in context.
Auto Compare
The diff updates instantly as you type — no button needed. Swap the two panels with one click to reverse the comparison.
100% Private
All comparison happens locally in your browser. Your text never leaves your device — no server, no upload, no tracking.
