The Context Engine for Physical AI.

PlexMesh turns the frontline expert's first person perspective into permissioned, model ready intelligence for AI agents and robotics.

Built for the deskless workforce, where downtime costs millions and error is not an option.

The permissioned learning loop

Every output earns the right to learn.

01 · Field

Captured from the inside.

The expert's own first person view, recorded on site. The most expensive 20 percent of physical data, the edge cases a crawler never sees.

02 · Edge

Processed where it happens.

Everything runs at the edge. No cloud streaming, and no raw footage ever leaves the site.

03 · Context graph

Compiled, not exposed.

Real work becomes a permissioned, model ready representation. What happened, what was decided, where a human corrected the machine.

04 · Mandate

Sealed with the right to learn.

Every output carries consent and provenance. Auditable, scoped to allowed use, and never about the individual.

The market reality

Cloud AI is blind to the physical world.

The gap

80% of work has no data trail.

The global deskless workforce runs the high stakes physical world, yet the internet never describes it. The next generation of physical AI and robotics cannot be trained on web text. It has no model of expert intuition, of how a real environment shifts under pressure, or of why a master overrides the manual at the exact moment it matters.

Our answer

The missing human graph.

PlexMesh captures the most expensive 20% of physical data, the edge cases, from the expert's own point of view. We turn real on site visual context, task structure, and the moments a human corrects the machine into permissioned intelligence an AI can actually learn from.

Core infrastructure

Private by design. Built for zero tolerance.

Three guarantees that let an enterprise hand us its most sensitive site, before any model learns a thing.

01 / Zero trust

Private by Design

Built for zero tolerance environments. Visual and task data are processed at the edge. No cloud streaming, and no raw footage ever leaves the site. It is used only for safety and task context, never for performance tracking, and never tied to an employment decision.

Compliant by design with enterprise labor and privacy standards.
02 / Context aware

Context-Aware Copilot

In a critical moment, a talking AI is a hazard. PlexMesh reads the task context and goes silent when it matters, surfacing a single minimalist highlight or a haptic cue instead of a voice in your ear.

Lightweight physiological signals act as one supporting cue for task load and safety. Not emotion, not medical, not a productivity score.
03 / Hands free

Wearable Command

Keep sterile gloves clean and hands on the tools. A subtle, deliberate gesture casts complex schematics to the nearest screen. Cross device, hands free, zero menus.

Built for the highest stakes

Where downtime is catastrophic.

Two beachheads where a stopped machine burns money by the minute, the data can never touch the cloud, and there is zero margin for error.

Beachhead 01

Semiconductor fab

Photolithography tool maintenance. A halted tool burns revenue by the minute, and the cleanroom is a place no outside model can ever see.

Beachhead 02

Emergency medical devices

MRI and ventilator service. Failure is measured in lives, not only in dollars, and the data is the most sensitive there is.

A fab line is down. A photolithography tool has faulted mid run, and every minute offline is revenue lost.

01 · Detect
Read the moment
The field engineer hits a critical fault deep in the tool. Edge sensors register rising task load as a complex, high pressure step begins.
02 · Adapt
Go quiet
The system mutes every audio prompt and projects one high contrast focal ring on the faulty module. Nothing else competes for attention.
03 · Control
Hands stay on tools
Without setting down a tool, a single micro gesture casts the full schematic to the tablet beside the engineer.
04 · Record
Becomes an asset
The successful fix is anonymized and written into the fab's own private Work Graph. Under strict EEOC aligned limits it never scores the individual. It becomes the correction data that will one day train the machines.
The master plan

From copilot to command layer.

Phase 1 · Today

Frontline Context Copilot

Immediate ROI for field engineers and lab technicians. Less downtime, and faster onboarding of the tacit expertise that usually walks out the door. Built for the 80% the software industry forgot.

Phase 2 · Tomorrow

Human Context Graph

The definitive, permissioned dataset of human and physical interaction. Task structures, edge cases, and failure modes that no crawler can ever reach.

Phase 3 · Future

Body Command SDK

The standard non invasive protocol for people to command robotics, AR and XR, and AI agents. Safely, and seamlessly.

The web was finite. The physical world is not.

Why us

Built from primitives.

PlexMesh isn't starting from a slide. The system is built from primitives already tested in real software: provenance, deployment context, command, and permission. Together they become the permission layer for AI learning from human reality.
Founder

Harvie Chen.

Founder working at the boundary where AI meets the physical world: AI systems, neurotech, and the trust infrastructure that lets them touch real human environments.

Biomedical engineering and neuroscience by training; medical AI at Philips; commercial problem solving at McKinsey. PlexMesh began as a narrower biosignal authentication idea. Through customer discovery and MIT Media Lab product validation, the deeper problem surfaced: how do we let AI learn from the real world without turning it into an unconsented data mine?

In 2026, self funded discovery across CES, JPM Healthcare Week, and deep tech rooms in Boston, San Francisco, and New York turned that question into a thesis, and a pivot.

The work here is how it gets tested with real users, in real conditions. Each prototype is a primitive of the permission layer for AI learning from human reality.
