Free HTML diff
Compare two HTML files: the code and how they look
Your AI rewrote the page. What actually changed? Paste both versions to see every added and removed line, then flip to see them rendered side by side. Nothing is uploaded; it all runs in your browser.
How it works
01
Paste or load both
The original and the changed HTML, from a file or straight from your AI chat.
02
See what changed
Added lines in green, removed in red, with line numbers for both files.
03
Check it visually
Flip to side by side to see whether the change looks the way you meant.
Questions
How do I compare two HTML files?+
Paste each version into the boxes above, or use Load file. The differences appear instantly, line by line.
Is my HTML uploaded anywhere?+
No. The comparison runs entirely in your browser.
Can I see the visual difference, not just the code?+
Yes. Switch to Side by side to see both versions rendered next to each other.
How do I keep track of versions my AI generates?+
In Kenso every version lives on the same link with the comments it received, and your AI tool (Claude, ChatGPT, Cursor…) can send the next version for you.
Kenso
The review home for AI deliverables
Claude, Cursor or ChatGPT push HTML, PDFs and images straight to Kenso. Your team pins comments right on them, and the AI reads the feedback back to ship v2 on the same link.
