Why convert presentations to Markdown before using AI?
▾
Structure survives perfectly
A PPTX file is a ZIP of XML — AI can't read it directly. Converted to Markdown, every slide title becomes a
## heading and every bullet a - list item. The deck's logic is fully intact.80–90% fewer tokens
A 30-slide deck sent as a PPTX would consume thousands of vision tokens per slide. As Markdown text, the same information costs a fraction — so you can fit entire presentations in one prompt.
Works with any model
Claude, ChatGPT, Gemini, local Llama — none of them can open a raw PPTX. Markdown is universal. Paste it and ask: summarise, translate, write follow-up emails, generate quiz questions.
Speaker notes included
Optionally extract speaker notes as blockquotes below each slide. Notes often contain the real explanation behind each slide — critical context AI would otherwise miss entirely.
Supports .pptx files (PowerPoint 2007+). Older .ppt files aren't supported — resave from PowerPoint as .pptx first.
