What is Presentation?
Presentation edits .pptx files directly and keeps the parts it doesn’t touch, so decks round-trip with PowerPoint users. Start from a template or a blank slide, add text, shapes, tables and images, and ask the AI assistant to draft slides or write speaker notes. When it’s time to present you get notes, the next slide, a timer and a laser pointer.

- AI assistant drafts slides, rewrites text and writes speaker notes
