Why this diff tool is useful
A good diff checker should do more than say “these texts are different.” It should make revisions easy to inspect. This page highlights additions and removals at word level, which makes it useful for code, policy drafts, content edits, contracts, prompts, and logs.
The comparison runs in your browser with the jsdiff library. For normal use, the text you paste is not uploaded to Mini-Tools.uk, which makes the tool suitable for quick private review before sharing or publishing content.
Can I compare code?
Yes. It works with plain text, code snippets, article drafts, notes, prompts and document revisions.
When should I use inline view?
Inline view is best when you want to read one combined output and quickly spot edits.
When should I use split view?
Split view is better for reviewing two versions side by side, especially for code and longer documents.
Common ways to use a text diff checker
- Compare two versions of an article, blog post, email or product description before publishing.
- Check code changes when you only have two pasted snippets instead of a full Git workflow.
- Review small policy, contract or terms updates by highlighting changed wording.
- Compare prompts, logs or configuration text to find the exact edit that changed the result.
