How to compare two texts and find changes When edits are small but spread across a long document (or code snippet), it’s hard to see what changed. Compare side - by - side in your browser with no installation. Useful for writers, reviewers, and developers. Useful when: • reviewing revisions • comparing configs • checking copy changes When you have two versions of a document or snippet, finding what actually changed can be hard—especially with long text or small edits spread across multiple lines.
Compare two texts and highlight differences instantly. Find changes between versions, code, or documents.

Why you may need this tool
When two versions of a document or configuration look similar, it is easy to miss a small but important change. Whitespace, punctuation, and single - line edits can affect behavior, especially in JSON/YAML and other structured text. A diff view makes changes explicit. It helps you verify what actually changed and prevents accidental omissions during review or publishing.
How to use
Paste the original on one side and the updated version on the other side, then focus on highlighted differences.
- Paste the original text in the left panel
- Paste the modified text in the right panel
- View highlighted differences instantly
- Copy or export the comparison result
Examples
Benefits & differentiators
Diffing reduces review time by showing additions, deletions, and modifications clearly. This supports safer edits in policy text, announcements, and technical configuration. It also improves communication: instead of describing changes verbally, you can point to exact differences when collaborating with teammates or stakeholders.
Who this is for
Recommended if you: - review text changes for publishing or compliance - compare configuration before and after deployments - need to explain what changed to another person - want a safer, faster way to spot small edits
