CheckDiffs
See what an AI edit changed. No account for the basics.
Paste before & after — see what an AI rewrite actually changed. CheckDiffs is a free, in-browser side-by-side diff (Monaco). Built for vibe-coding and long chat refactors: jump hunks, merge lines, no account for basic compare, nothing uploaded for that flow. Not a PDF/Excel suite. Not “better than VS Code.” Just a simple standalone clipboard moment. Try it: https://checkdiffs.com Privacy: https://checkdiffs.com/privacy
I built CheckDiffs while vibe-coding with Gemini. I'd generate a new version, then another, and I needed a quick way to see what the model actually changed before I kept it — without uploading code or making an account just to look.

Hi Product Hunt — I'm FT.
I built CheckDiffs while vibe-coding with Gemini. I'd generate a new version, then another, and I needed a quick way to see what the model actually changed before I kept it — without uploading code or making an account just to look.
