Spot every change between two texts. Side by side.
Paste a before and an after and get a precise diff — line by line, with the exact words that changed highlighted. Switch between side-by-side and inline. Nothing is uploaded.
FAQ
Is my text uploaded?+
No. Both blobs are compared entirely in your browser — they are never sent to a server. We do count anonymous, aggregate usage on our own server (a page view, that a diff was run) — never your text.
What exactly gets highlighted?+
First a line-by-line diff marks each line as unchanged, added or removed. When a line is changed rather than wholly replaced, the tool also runs a word-level diff so you see which words changed — removed words are struck through on the left, added words are highlighted on the right. The chips up top tally added, removed and unchanged lines.
