Products

What we build.

Three product lines — from governable AI infrastructure to a private space for the inner life.

Each product is independently useful. Together they span machine and mind. Built, documented, and maintained by Span Brain LLC.

Machine ↔ Mind

OpenPRX · Driftvale · Ramflux

01 · OPEN AI INFRASTRUCTURE

Live

OpenPRX

An open-source AI engineering pipeline — from planning to protection.

A family of open tools spanning Plan → Think → Build → Ship → Protect. OpenPR is growing from sprint planning into a general-purpose workspace with a universal form builder; PRX is an AI runtime that writes code and plugs into any messenger to route and coordinate work. Self-hostable, auditable, yours.

OpenPR — universal forms & team workspace
PRX — AI runtime & message hub
PRX-Memory — cross-session memory
Self-hosted by default

02 · EMOTIONAL HABITAT

Beta

Driftvale

A trace-based emotional habitat — every trace you leave, it understands you a little more.

Leave traces through gentle measurements and quiet reflection. Your room remembers them; some drift into the world where strangers leave stamps; Echo turns accumulated traces into deeper understanding; over time, a personality mirror grows clear. Not a diagnosis or a chatbot — a low-pressure space for the inner life.

Trace, Room & Drift
Stamp — quiet stranger responses
Echo — deeper insight
A long-term personality mirror

03 · PRIVATE FEDERATION

Coming soon

Ramflux

Federated, self-hostable private messaging where AI and people share one space.

Memory in flux. Every private node is a complete unit; the company runs only a thin control plane; an invite-only alliance lets nodes find each other. Files, voice and agents all live on your node. Built on a post-quantum federated identity (PQFIP) where identity is an evolving lineage, not a static key — and where agents render dynamic UI alongside human conversation.

Self-governing private nodes
Open server & SDK, closed client
Post-quantum identity (PQFIP)
An IM for AI + people

What's next

Start with one product. Draw the next.

Each product stands alone. When you want it private or end-to-end, we'll deploy it with you.
