I've been using VSCode with aider, but with auto-committing turned off. VSCode has a thing where changes not yet checked into the tree are highlighted in the scrollbars -- blue for modified, green for added, red for removed. You can then click the colored part of the sidebar to see a diff.

Just for fun I typically also have an emacs window open; "git diff > working.diff" lets you see the diff, then "C-c C-c" on a diff hunk will take you the place in the file where that change was made.
