Source + preview, not WYSIWYG
Edit real Markdown. Switch edit / split / preview. Ordinary .md files stay portable — open them anywhere, diff them, let an agent rewrite them.
Your notes. Your Drive. Your agents.
A local-first Markdown notebook. Sync with Google Drive or Dropbox so you — and your AI agents — can read and write the same library, on any device.
Local editing is always free. No subscription. No iCloud. No self-hosted server.
Why not just use Obsidian?
Multi-device sync that agents can reach — without locking you into a closed subscription sync, and without a .git explosion on your phone.
ObsidianSubscription sync
Official sync is a subscription — and a closed pipe. Hard to hand to a remote AI. GitHub sync is painful on phones; stacking GitHub with iCloud balloons .git until storage and file counts explode.
TyporaWYSIWYG
Great for polished writing. StoatMD keeps plain Markdown source with a separate preview (edit / split / preview) — better when you want the file itself, and agents that rewrite .md.
Miaoyan-class Apple-only
Close in spirit: native, light, source + preview, ordinary .md files. But often locked to the Apple ecosystem — and usually cannot let an agent remotely push notes into the same library.
StoatMDBuy once · your cloud
Sync with Google Drive or Dropbox. Local forever free. Unlock sync with a one-time purchase — so you and your Personal Agent can archive into the same folder, from desktop or phone.
Built for notes agents can touch
The library lives in a folder you own. Sync is alignment to your cloud — not a second home for your writing.
Google Drive & Dropbox
Phase one sync providers — both first-class for global users and Personal Agents. No iCloud. No self-built server. No WebDAV in v1.
Agents read and write the same vault
Typical flow: ask Grok Bot to research, then archive into your notes. Because the vault is on Drive or Dropbox, a remote agent can push Markdown without a local MCP bridge.
Buy once. Local always free.
Editing on your Mac costs nothing. The moment you turn on sync, you hit a paywall — one purchase, not a subscription bolted onto your notebook.
