About

Vaultlens

Features
Read full description

See what's happening inside your Obsidian vaults — without opening Obsidian. Vaultlens is a fast, private inspector for the Obsidian vaults you keep in iCloud Drive. Point it at a vault folder and it reads the structure and metadata directly — giving you a health score, activity trends, link maps, and signals of AI-agent editing, all computed on your iPhone. Private by design. Vaultlens has no servers, no analytics, and makes no network connections whatsoever. Your notes never leave your device. Nothing is collected, tracked, or shared — because there's nothing to send it to. FREE • Single-vault dashboard: file & folder counts, size, folder depth, file-type breakdown • Most-recently-edited, last-scan time • Activity heatmap (GitHub-style) • iCloud sync status and .git / .obsidian detection • Agent-activity summary and vault growth • Link-map totals PRO • Vault health score — a 0–100 read on freshness, conflicts, structure, and sync, with the full breakdown • Multiple vaults + side-by-side comparison • Home Screen & Lock Screen widgets • Deep-scan link engine: word/line counts, tags, wikilink graph, orphans and broken links • Agent signals: per-signal and edit-session breakdown, agent-vs-human classification, anomaly and conflict flags • Shortcuts & Siri: vault summaries, rescans, and agent-config listing Works with whichever AI coding agent you use — Vaultlens detects AGENTS.md, CLAUDE.md, GEMINI.md, GitHub Copilot and Cursor configuration, and surfaces only the ones your vault actually uses.
