Diffrs

Diffr is a fast, private way to see exactly what changed between two pieces of text. Paste any two versions — a contract clause, a config file, a code snippet, a message draft — and Diffr instantly highlights every difference, word by word.

Matching text is marked in green in both boxes. Anything that's different shows up in red, only in the box where it changed, so you can tell at a glance whether two versions are identical or exactly where they've drifted apart.

No more reading line by line hoping you didn't miss a single edited word. No more guessing whether "final_v2" really matches "final_v3." Diffr shows you in seconds.

PRIVATE BY DESIGN
Diffr works entirely on your device. There's no account to create, no sign-in, and nothing is ever sent to a server. Your text stays yours.

WHO IT'S FOR
Anyone who needs to catch the difference between two versions fast: writers comparing drafts, developers reviewing snippets, professionals checking redlined contracts, or anyone proofreading a message before they hit send.

Paste. Compare. Done.
