As answered by people managing Udemy and Diffract.
Diffract's answer:
Diffract is a purpose-built desktop diff tool that handles far more than plain text. A single app compares text, binary (hex view), images, PDFs, Word documents, Excel spreadsheets, ZIP/tar archives, and Git commits - all in a multi-tab interface. On top of the standard Myers diff, it offers Patience and Histogram algorithms per comparison, AST-based semantic diff that understands code structure (not just line changes), and automatic moved-block detection. It also runs fully headless as a CLI tool for use in CI pipelines.
Diffract's answer:
Diffract is purpose-built, so it supports file types (PDF, Word, Excel, archives), workflows (three-way merge, Git browsing, semantic diff), and UX features (drag-and-drop, OS context menus, in-panel editing with undo/redo, minimap, search) that e.g. an IDE's diff panel simply doesn't cover.
Diffract's answer:
Software developers and DevOps/SRE engineers who compare code, config files, and build artifacts daily. A secondary audience includes QA and release engineers who need to diff generated outputs and directory trees, and technical writers or analysts who compare Word documents, PDFs, or Excel exports without wanting a cloud-based or subscription tool.
Diffract's answer:
Flutter and Dart (cross-platform desktop UI, targeting Windows, macOS, and Linux).
