Why SlideDown?

Most presentation tools force you to choose: **developer-friendly** (Marp, Slidev) or **design-quality** (Canva, Gamma). SlideDown bridges that gap.

• Markdown-native — write content, not wrestle with UI
• 6 professional themes — designed, not default
• One command — no config files, no build steps
• Keynote-compatible — .pptx opens natively on Mac
• Git-friendly — your slides are just .md files
• Smart layouts — auto-detects titles, quotes, tables, code blocks
