what AI can build

Use a local Markdown folder, git/Syncthing/iCloud/Drive for sync, and optional scripts for backlinks/search.

If you already accept local Markdown files, syncing folders across devices is a solved problem; the hard part is not the app, it is conflict-free convenience.

The honest tradeoff

why people still pay

They pay for no-drama sync across devices while keeping Obsidian's local-first model.

the prompt

Catalog estimate
Build me a sync setup for my Obsidian vault to replace Obsidian Sync. Requirements:

- This is plumbing, not an app: the vault is a folder of Markdown files, sync it with
  git. Syncthing is the zero-history alternative; use git here because I want history.
- A small watcher (Node + chokidar + simple-git, or a plain bash script on a
  systemd/launchd timer, pick the simpler) that debounces 30 seconds after the last
  change, commits with an auto message, and pushes to a private GitHub repo.
- On start and every 5 minutes: pull with rebase. On conflict, never lose data: write
  the incoming version as <name>.conflict-YYYY-MM-DD.md, keep mine in place, and log it.
- .gitignore for .obsidian/workspace* and .trash so device-local state does not ping-
  pong between machines.
- A `vaultsync status` command showing last push/pull time and any outstanding conflict
  files.
- Mobile: point a git client (Working Copy on iOS, MGit on Android) at the same repo.
  Document that in the README, do not build mobile anything.
- The repo stays private; token in .env or the system git credential helper. No accounts
  beyond GitHub, no telemetry, notes stay plain Markdown on disk.
- Out of scope: an encrypted-vault workflow and a version-history UI. git log is the
  history.
- README: second-machine setup steps and the conflict-file convention.

questions

Can AI replace Obsidian Sync?

Likely for the core workflow, based on an editorial catalog judgment. This entry is not a verified build yet; use the prompt as a starting point and validate the result against your own acceptance criteria.

How much does Obsidian Sync cost?

Obsidian Sync is listed at about $5/month (Sync, checked 2026-07-30), or $60 per year. This is a pricing reference, not evidence of a completed replacement or realized savings.

What do I lose by replacing Obsidian Sync?

Honestly: official mobile sync polish; conflict handling; version history UI; encrypted vault workflow; Obsidian support. If any of those are load-bearing for you, keep paying.

Is there an open-source alternative to Obsidian Sync?

Yes — Syncthing (Open-source continuous file synchronization that can replace much of Obsidian Sync for tec). Using prior art is also a valid exit; the prompt is for when you want it exactly your way.
