Can you include screenshots in your readme?

Also does it only work for staging and unstaged changes? I use jj so I need to be able to point it at commits since jj has no staging it just creates a new git commit snapshot every time you run any jj command.

There is a screenshot in the README.

There is a video here: https://x.com/cnakazawa/status/2055881241677668637?s=46&t=BS...

It works for any staged, unstaged or untracked file in a repo. It does not have support for mutations (like staging or unstaging a change) yet. It does not yet work for specific commits but should be super easy to add.

Who knew that the killer task for LLMs would be "recreate existing things that exist without me mentioning them by name, based on a worse alternative as the example". Kaleidoscope exists. File Merge exists.

Codiff is faster and scales to larger commits than those.

:) We are all converging on the same problems and tooling to fix them. Built this in the last couple days to review changes done by claude on a hetzner box(over tailscale on my phone) and leave comments before pushing to remote : https://github.com/livetemplate/prereview . Runs everywhere and can has a claude skill: /prereview which starts a new instance for the current changes. Has a “Hand-off” button to signal clau…

Would love to see some screenshots in your readme of this!

Yeah the project is right out of the oven so will add some usage gifs shortly to the repo. Meanwhile here are some screenshots on imgur: https://imgur.com/a/zxZo651

That’s awesome! I built this specifically as a GUI because it’s become too much code to effectively review in the terminal for me.

exactly. LLM code output is so high that it has become unreasonable to review the code in terminal or ide

Is diff viewer the 2026 todo list? List of vibe coded alternatives: - revdiff: https://github.com/umputun/revdiff - hunk: https://github.com/modem-dev/hunk - diffnav: https://github.com/dlvhdr/diffnav - diffx: https://github.com/wong2/diffx - lumen: https://github.com/jnsahaj/lumen

4 of these are TUIs. I built Codiff specifically because TUI review became overwhelming to me. One of them is a web view, I prefer a native app window (it’s JS either way, ofc).

Also, I never wasted time building todo apps. Now I can build apps that help me do my job that I wouldn’t have had the time for without AI.

You're seriously suggesting that an electron app you vibe coded in two days is more performant than native code that's been developed and improved and tweaked over literal decades?
