## Description

Open your Markdown files with Mermaid diagrams, Leaflet maps, callouts and entity highlighting — faithful to ok-ia.ch, 100% offline.

OK-ia Markdown Viewer displays your Markdown files exactly as the ok-ia.ch viewer does —
same typography, same colours, same rendering pipeline.

FEATURES
• Faithful Markdown rendering (headings, tables, lists, quotes)
• Mermaid diagrams: flowchart, sequence, gantt, pie, mindmap — with full-screen zoom
• Leaflet maps (Obsidian plugin style): positioned markers, CARTO/OSM base maps,
  full-screen button for portrait or landscape navigation
• Obsidian callouts (note, tip, warning, bug…), wiki-links, entity highlighting (NER)
• Document summary by Apple Intelligence — on-device, properly formatted (chapters, bold, lists)
• Chat with the document: ask questions, structured answers grounded in its content alone,
  generated on-device (summary and chat require an Apple Intelligence capable device)
• Siri, Spotlight and Shortcuts: “Open the latest report”, “Summarise a report”…
• Automatic table of contents, in-document search, adjustable text size
• Paginated PDF export (A4 or Letter), Word and PowerPoint; .md file sharing
• Dark mode, portrait and landscape, iPhone + iPad + Mac
• Interface in French, English, German, Spanish and Italian
• 100% offline: rendering, diagrams, callouts and the AI summary need no connection
  (only the map base tiles load online)
