Summon once.
Remember forever.

A familiar is an AI agent with a memory, bound to your project. Close the terminal and the context, conventions, and unfinished work stay.

I the boundary surface · runtime · project

Three layers. Only one is yours to defend.

OpenCoven is the substrate under your AI tools — an agent’s memory lives inside your project, not in the tool. Change the surface as often as the work calls for it. Continuity lives in the substrate, and the project boundary never leaves your machine.

Surface

Desktop and Mobile Applications

Swappable by design.

Codex, Claude Code, Coven Code or Cave — pick the interface that fits the task and change it whenever you like.

Runtime

Portable Memory for Agents

Continuity lives here.

Sessions, familiar memory, adapters and tool permissions live here — between the surface you use and the project you own.

Authority stops here.

Filesystem, Git, terminals and docs stay inside the project you named. Provider keys stay with the provider.

II the surfaces start where the work is

One substrate. Three ways in.

Every surface writes to the same local record. Start wherever the work is — each path leads to its own verifiable Quick Start.

Connect the desktop app to its local Coven runtime, with an optional iOS companion handoff.

A visual home for familiars, projects, and sessions, with an optional iOS companion.

III the invocation ~2 minutes · no account

Three commands to first summon.

Nothing to sign up for. Install the runtime, let it read your project, then bind a familiar to it — each step runs as you scroll.

  1. + @opencoven/cli@1.4.2

    coven — the local-first familiar runtime

    Expect: the help screen lists every top-level command.

  2. ✔ project detected ./opencoven

    ✔ harness codex (ready)

    ✔ daemon running

    Expect: actionable guidance for any missing setup.

  3. session 01JC7F · feat/runtime-attach

    harness codex status complete

    memory project record updated

    Expect: the history row shows id, harness, title, status.

coven — zsh 01 · Install

❯npm install -g @opencoven/cli

+ @opencoven/cli@1.4.2

coven — the local-first familiar runtime

Expect: the help screen lists every top-level command.

After the third command the familiar is yours — pick a surface and its guide carries you the rest of the way.
