Show HN: Git-knife – edit commit messages, authors, and dates like a spreadsheet

Git-knife is a desktop GUI that lets you edit git commit metadata—messages, author and committer names/emails, and dates—directly in a spreadsheet-like interface. Unlike existing tools that treat dates as immutable, git-knife provides full control, including bulk find-and-replace with regex. It safely rewrites history by shelling out to git and using commit-tree, ensuring file contents never change. With previews, automatic backups, and push warnings, it's perfect for fixing typos, correcting emails, or adjusting timestamps across many commits.
