# MarciaOS

> The operating layer underneath everything: identity, workspaces, and AI routing, unified.

<Note>
  **The operating layer underneath everything.** Identity, workspaces, and AI
  routing unified across every tool your team uses.
</Note>

MarciaOS is the foundation the rest of the Marcia platform runs on. Instead of
stitching together a dozen disconnected tools, your organization gets one
operating layer that handles who can do what, where work happens, and how AI is
applied, consistently, everywhere.

## What it gives you

<CardGroup cols={3}>
  <Card title="Unified identity" icon="id-badge">
    One place to manage people, roles, and access across all your Marcia
    surfaces and connected tools.
  </Card>

  <Card title="Shared workspaces" icon="users">
    Teams, clients, and projects organized in workspaces that carry their
    context wherever the work goes.
  </Card>

  <Card title="Multi-provider AI" icon="wand-magic-sparkles">

    result without managing models yourself.
  </Card>
</CardGroup>

## Raise the floor, unlock the ceiling

Because MarciaOS sits underneath everything, it sees every action across your operation, so it can lift your weakest performers and get out of the way of your best.

<CardGroup cols={2}>
  <Card title="Help your worst become better" icon="arrow-trend-up">
    Spot where people and agents are struggling and close the gap, so your lowest performers come up to standard instead of falling behind.
  </Card>

  <Card title="Unlock your best" icon="trophy">
    Give your top performers room to run, with the access and resources to do more of what is already working.
  </Card>

  <Card title="Every tool call, monitored" icon="magnifying-glass-chart">
    Watch every single tool call and usage event across the platform in near real time. Nothing happens off the books.
  </Card>

  <Card title="Manage usage live" icon="sliders">
    Act on what you see as it happens: adjust access, routing, and limits in near real time, not after the fact.
  </Card>
</CardGroup>

## Who it's for

MarciaOS is built for organizations that want AI woven through their operations
rather than bolted on, businesses running multi-team operations, institutions
serving many constituents, and enterprises that need one consistent layer of
identity and intelligence across everything they do.
