A desktop app for Windows, macOS and Linux that opens, edits and saves PowerPoint files without an account. Edit right on the slide with a PowerPoint-style ribbon, slide thumbnails, a format pane, speaker notes and slide show, and Ctrl+S saves the same .pptx. Sign in to create a deck with AI that lands straight in the open presentation, or turn on Connect AI apps so Claude Desktop, Claude Code or Cursor can change slides over MCP.
