Original Text
I wanted a journal that's portable in two senses: it's just my own plain-text Markdown (no vendor lock-in) and it works across my phone and laptop, even offline. So I built an Android app: Notedog.
It keeps your journal as Markdown files on the device (point it at your own Git repo for history + backup). The twist: the app runs a small web server, so you can open and edit the same journal from any browser on your network — your phone is the backend. It works without an internet connection; no journal content is persisted on my servers. Also, it can connect to AI agents like Claude and Codex over MCP. Access is scoped and revocable.
Optionally, you can reach it from anywhere over a built-in HTTPS tunnel (paid subscription). Or reach it privately over your own Tailscale network — no subscription.
Would love feedback. Play Store: https://play.google.com/store/apps/details?id=run.notedog
