The TetraKits Text Diff runs entirely in your browser — free, private, and ready on mobile or desktop.
Overview
Not every text comparison needs a full git diff. Config tweaks, contract revisions, and email draft edits benefit from a quick side-by-side check — paste both versions and see exactly what changed without cloning a repository.
How to use the text diff
Paste original and revised text to see line-by-line differences — additions, deletions, and changes highlighted in a readable diff output, all processed locally.
Common use cases
Paste original and revised text to see line-by-line differences — additions, deletions, and changes highlighted in a readable diff output, all processed locally. Bookmark the tool for quick access during projects.
FAQ
Does this do character-level diff?
This tool compares line by line. Put each change on a separate line for clearest results.
Can I diff code files?
Yes. Paste code snippets or config files into both fields and compare.
Is there a line limit?
Browser memory applies. Very large files (100K+ lines) may be slow — split into sections if needed.
Can I export the diff?
Copy the diff output from the result panel for pasting into tickets or emails.
Is this text diff tool free?
Yes. Unlimited comparisons with no signup.
