What happens when a provider connection is unavailable?

EmailOS cannot complete provider-dependent work while that connection is unavailable; review the message and reconnect through the supported path.

What data remains on the Mac during core drafting?

Core drafting data remains within the documented local processing boundary on the Mac; provider and administration paths are separate.

Lithi EmailOS

A private AI email agent for your Mac

Q: Does Lithi start new conversations?

No. EmailOS prepares replies to eligible inbound messages; it does not start a new conversation for you.

EmailOS is a native Mac app that prepares eligible inbound replies in your voice. Review, edit, skip, or choose Send when the draft is ready.

Step 1 of 3: Use approved knowledge with an eligible reply

Review and approval

Simple steps from message to action

01

Notice the signal

EmailOS reads the authorized email record and metadata needed for the workflow you selected.

02

Check the suggestion

A draft stays visible and editable. Confirm the recipient, context, and wording before you continue.

Local boundaries

Native on your Mac, scoped to your workflow

Core work stays local

Core drafting runs in the native Mac app. Provider sign-in, account, license, and update paths remain separate, and the app only uses records and metadata your setup authorizes.

EmailOS FAQ

Common questions, answered plainly.

Which inbound emails are eligible for a draft?

An inbound message is eligible when it matches the accounts, folders, sender, topic, and confidence rules you approve.

Where does EmailOS place a prepared reply?

EmailOS places the prepared reply in your provider's Drafts folder for your review.

What happens when Lithi is not confident enough?

EmailOS leaves the message for your attention when it lacks sufficient confidence or approved context.

Can I review why a draft used a rule or source?

Yes. The draft can show the applicable rule or approved source context so you can review its basis.

Can I edit, skip or remove a draft?

Yes. You can edit, skip, or remove a prepared draft before choosing whether to send it.
