One-way vault sync from PC to Android over local WiFi — no cloud, no account, no cables.
- PC runs a local HTTP server exposing your vault's files
- Android fetches a file manifest, diffs it against local state, and downloads only what changed
- PC is the single source of truth — mobile vault is kept in sync automatically
Both devices must be on the same WiFi network. Obsidian must be open on your PC.
Search for Mobile Sync in Obsidian's community plugin browser.
