Paste two text snippets - logs, code, config, prose - and see every addition, deletion, and change highlighted at the word level. Side-by-side or unified-diff view. Works for plain text, source code, JSON, YAML, CSV, markdown. Up to a few MB per side comfortably in the browser.
When to use this
Use when: reviewing what changed between two log captures, spotting accidental edits between two versions of a contract, comparing two AI outputs, diffing two config files before deploying, finding the typo that broke a copy-paste.
Frequently Asked Questions
Is this the same as a Git diff?
Visually similar but algorithm-different. Git uses Myers diff at the line level. Our tool uses a line + word-level approach so you see word-by-word changes inside a line - more useful for prose / config but slightly different output than `git diff`.
Can I diff two JSON files?
Yes - paste them as text. For semantically-aware JSON diff (where key order doesn't matter), sort the keys first using our JSON Formatter's 'Sort keys' option, then diff.
