Your life is the input stream.

A todo app and journal that writes plain markdown on your own computer — reachable from anywhere, readable by your agents. Type it messy; it files itself.

I heard:

Private beta. Invites go out in small batches — no spam, ever.

what it is

Capture, reflect, review

Tasks that file themselves

"pay the water bill friday" becomes a dated, tagged task. Projects, priorities, repeats — parsed from plain words, previewed before you commit. It learns your habits as you correct it.

A journal that stays home

Timestamped thoughts, moods, whole pages — written to files on your disk, not somebody's cloud. No account required to keep your own memories.

Files you actually own

Everything is one markdown line in a folder on your computer. Obsidian opens it. Grep works. Cancel any time and lose nothing — the files were always yours.

Agents welcome

Connect Claude, ChatGPT, Gemini — any MCP agent — to your stream, live today: it reads your day, files your tasks, remembers what you tell it, searches your journal. Plain text is the format agents already speak, and the memory travels with you between them.

no database · no lock-in

The whole database is a folder

how it works

Your computer is the server

Your files stay on your machine. The stdin host runs quietly on your computer, next to a folder of markdown.

A tunnel makes it reachable. Your phone and laptop talk to your files through an encrypted relay — no VPN, no port forwarding, and no copy of your vault in the cloud beyond a small encrypted slice that keeps the app working while your computer sleeps.

Agents plug into the same stream. One approval connects Claude, ChatGPT or Gemini to the same files, live — you choose what each may do, and every change they make is listed with an Undo.

Own your stream

We're inviting a small first batch of Obsidian users, self-hosters, and agent-builders.
