Text compare

Paste or import two texts, see line-by-line differences and merge what you want — all in the browser, with no data sent to a server.

Paste one text on the left and another on the right to compare.

Left (original) Right (changed)

What is a text comparer for?

A diff shows what changed between two versions of a file, an email, a JSON document or a contract. It is the same idea as Git, without a repository: you paste both sides, see insertions and deletions and choose what stays. Nothing is sent to servers — processing stays in your browser.

Features

Side by side

Edit both texts, import files and see the result immediately.

Merge by block

Each difference has arrows to bring the change to the left or restore the original on the right.

Unified diff

Copy or download a .diff on your computer. Nothing is stored on the MK3 server.

100% in the browser

Compare contracts, configs and code with no upload. The texts stay on your device.
