Private Text Difference Checker
A simple offline-capable review tool for drafts, metadata and configuration changes.
Try the tool
Your inputs are processed locally by this tool and are not intentionally uploaded. The website's existing Google Analytics tag may still collect ordinary visit/interaction metadata; do not enter secrets in a tool on a shared device.
How this tool works
This uses a longest-common-subsequence line comparison in local JavaScript. It works well for short texts and configuration files, but does not detect word-level edits or semantic similarity. Extremely large comparisons are limited to protect browser responsiveness.
Practical tip
Compare changes before updating ad copy, editorial drafts or configuration. Always inspect the whole context before accepting a changed clause.
This free tool is informational, with no warranty or professional advice. Check important outputs independently.
