Can one client see another client's information?

No. Each client has its own workspace. Data, connections, search and scheduled work stay inside it, and you switch between clients from one account.

Can a client get my frameworks out of Erin?

No. Clients can't open, search, download or export your methods. Erin applies them to their work and won't hand over the files.

How much upkeep does each client need?

Less than a general assistant. Erin reads each client's connected email, calendar, documents and meeting notes as they change, so you review what moved instead of rebuilding the context every month.

Can I keep using Claude?

Yes. EmergentOS routes work between leading models, including Claude, so you keep the model quality and add client workspaces, plans and access control around it.

For fractional leaders:Why not just use Claude or Codex?

In EmergentOS: Each workspace updates itself from that client's own tools.

A client asks Claude for every file you've uploaded. What happens?

In EmergentOS: Erin applies your methods and won't hand over the files.

In EmergentOS: Ask Erin. The brand, the plan and the answers are already there.

Is Acme's CFO more confident than last quarter?

Claude falls behind OpenAI next month. What now?

In EmergentOS: We move Erin to the leading model. You migrate nothing.

What that looks like

The parts a general assistant leaves to you

One workspace per client

Switch clients in one click. Nothing crosses over.

Your methods stay yours

Clients use Erin with your methods. They can't open or extract the files.

Context that updates itself

Email, calendar, documents and meetings, read as they change.

Reviews that run themselves

An executive submits, the CEO responds, Erin chases.

When Claude or Codex is enough

They are excellent general assistants. Stick with them if:

You work with one client at a time and are happy to keep their documents current yourself.
Your clients already work in Claude or ChatGPT and will not adopt another tool.
You mainly need drafting, research or analysis rather than ongoing tracking.
