A desktop app for building animated product demos from a series of screenshots — screenshot capture, PowerPoint deck build, slide-to-slide interpolation, GIF/MP4 export.
Product demos usually get made one of two ways: record your screen for real (fragile, hard to edit, slow to iterate) or hand-animate the frames in a design tool (nice results, huge time sink). DemoAnimator hits a third point on that curve: capture screenshots, arrange them as PowerPoint slides with editable shapes and text, and let the app interpolate smooth animations between the slides. Iterate on the deck, hit export, get GIF/MP4 out.
Capture screenshots → Build PPTX deck → Edit in PowerPoint → Interpolate → GIF/MP4pptx_cli.exe, 39 MB). Exposes subcommands for PNG↔PPTX conversion, interpolation, shape propagation, and export. Called by the Electron frontend as a subprocess.
