Read full description

Constellation turns a folder of Markdown notes into a spatial "atlas" you can explore on iPhone and iPad. Select any local folder of .md files (from Files / iCloud Drive or on-device storage). Constellation parses structure and links (including [[wikilinks]]), then builds a navigable 3D constellation where ideas become places: clusters form naturally, connections become visible, and isolated notes stop hiding in plain sight. Constellation is not a note editor. It's a way to understand what you already have — faster than scrolling a list, and calmer than wrestling a web of tabs. What it understands • Plain Markdown files and folders • Wikilinks ([[like this]]) and regular links • Backlinks and "neighbors" of a note • Tags (#tag) and (when present) frontmatter metadata • File timestamps for "recent notes" views What you can do with it • See clusters and themes at a glance (by folder and tag) • Follow paths between notes and spot the "bridge" notes that connect topics • Surface orphans and dead ends, then decide what to link next • Start from any note and explore outward, one connection at a time • Keep your context: you're moving through the space, not hopping between screens Filters & lenses to cut noise • Filter by folder or tag • Show only high-degree hubs (or only low-degree, overlooked notes) • Highlight orphans • Focus on recent work • Reduce density for large vaults so the scene stays readable Designed for iPhone and iPad • Calm, cinematic 3D rendering with depth cues and subtle atmosphere • Tap a star to open its note; drag to orbit and pinch to zoom • Light and dark appearance, following your system setting • Adjustable density and progressive loading for medium-to-large vaults A clean reading experience • Open any note in a panel with crisp typography: beside the graph on iPad, as a sheet on iPhone • See outgoing links and tags alongside the content • Follow links from note to note without losing your place in the constellation Fast setup, no accounts • Point Constellation at a folder, index, and explore • Rebuild the index whenever your vault changes • Local caching for quicker reloads Made for people who live in Markdown Writers, researchers, developers, and anyone with a "second brain" full of links: Constellation helps you spot what's connected, what's missing, and what's worth revisiting. Offline-first and private by default Your files stay on-device. Constellation doesn't upload your vault, doesn't require an account, and doesn't modify your files — it simply indexes and visualizes them locally. Compatibility: works with Markdown vault folders from apps such as Obsidian and Logseq. Not affiliated with or endorsed by them.
