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 samepptx. 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.

Partial A basic PowerPoint-style editor is buildable, but opening and saving .pptx files without corrupting content or losing formatting requires deep knowledge of the OOXML spec that vibe coding won't reliably produce.
What it would actually take: Reading and writing pptx means handling the OOXML package (zip, relationships, DrawingML, slide masters, and themes) with round-trip fidelity so untouched content survives a save. Teams often build on an existing renderer or library such as LibreOffice's core or Aspose-like parsers, plus a custom text-layout engine for on-slide editing. The fidelity testing against real-world decks requires a specialist in document formats.
