OK-ia Markdown Viewer

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)
