Text diff / compare

Paste an original and a changed version below and this compares them line by line, highlighting what was added and removed. It's the same idea as a code diff in version control, and it runs entirely in your browser.

Added
Removed

Frequently asked questions

How do I compare two blocks of text?
Paste original on the left, changed on the right — it compares line by line and highlights additions and removals. Runs in your browser.
What is a text diff?
A comparison showing what changed between two versions — added and removed lines — the same idea developers use in version control.
Is it private?
Yes — computed in your browser; neither text leaves your device.
