Everything You Need to Compare Text

A complete diff toolkit that runs entirely in your browser. No server, no uploads, no compromises.

Character-Level Diffs

See exact changes down to individual characters within each line. Not just line-level, but precise word and character highlighting.

Syntax Highlighting

PRO

50+ programming languages supported. JavaScript, Python, Rust, Go, TypeScript, and many more with proper token colorization.

JSON & XML Structural Diff

PRO

Smart structural comparison that understands JSON keys, nested objects, and XML element hierarchy, not just raw text.

Export to PNG, PDF, SVG

PRO

Generate beautiful, screenshot-ready diff images for documentation, code reviews, and presentations.

How It Works

Three steps. Zero friction. No account needed.

01

Paste Your Text

Paste, type, or drag-and-drop text files into the left and right panels. Works with any text: code, prose, configs, data.

02

Instant Diff

Click Compare (or press Cmd+Enter) to see a highlighted diff in milliseconds. Choose side-by-side or inline view.

03

Export & Share

Export your diff as PNG, PDF, or SVG. Or generate a shareable link that encodes the diff in the URL, no server needed.
