By design
Built to be trusted.
Always on
A teammate that handles the busywork — triage, prep, follow-through — so your people spend time where it counts.
Knows your world
Grounded in your approved knowledge, with memory and context built for review and continuity.
Stays in bounds
Clear boundaries, governed actions, and honest escalation to a person when it should.
Pleasant to work with
Calm, clear, and helpful by design — never a toy, never adversarial.
Put a persona on your team.
We build with a small group of design partners first. Tell us about your team — we'll set up a working session.
Agency access
Open the Realtor Assistant workspace.
Approved agency users can sign in to access guided real-estate conversations, team setup, and approved workspace context.
Design-partner program
Shape it with us.
A few teams are building Persona OS with us, around real work. Early partners shape the roadmap and get hands-on support: discovery, a configured pilot, weekly review.

Weekly review
What partners say
Trusted by early partners.
Quotes are published with design-partner approval. Identities remain confidential during the pilot.
The product is genuinely good at what it promises. Briefs, follow-ups, and prep that used to consume entire mornings are ready before we ask — the time it gives back to our team every week is real.
Our productivity has measurably increased since we brought it into the workflow. Handoffs that used to stall now keep moving, and our agents spend the day with clients instead of on coordination.
What we are building
Shipping, in the open.
Governed model routing
Three-mode routing on Azure Foundry with a managed fallback — no black-box provider hopping.
Persona authoring + Librex
Author persona identities and knowledge, versioned and signed, served from one source of truth.
Tenant-isolated knowledge
Per-tenant knowledge with upload and retrieval, scoped so one workspace never sees another.
