What Sterling does
A real butler. In your machine.
Press a key.
Speak naturally.
Hold Ctrl+Alt+Space from anywhere on your machine. Sterling listens, thinks, and answers — in a refined British voice trained to be your butler.
Never forgets.
Every fact, every preference, every conversation — saved as plain text in your Documents folder. You can read them. You can copy them. You own them.
Anticipates you.
Morning briefing at 7 AM. Email triage on demand. Meeting prep before every call. Build your own with one sentence.
Reads. Replies. Books.
Gmail and Google Calendar, fully integrated. Sterling drafts replies, schedules meetings, surfaces what matters.
Sees your screen.
Open apps. Read what's on your screen. Type for you. Click for you. Sterling uses your computer the way you do.
"Of course, sir. Right away."
Sterling speaks with dry British wit, quiet competence, and unwavering loyalty. No "happy to help!" No corporate pleasantries. A real butler. The kind you'd find at a London estate.
The Real Difference
Your data never leaves
your machine.
Sterling has no database. No cloud. No telemetry. Your memories live in plain markdown files in your Documents folder. You can open them in Notepad. You can copy them to a USB stick. You own them forever. Even if Sterling vanishes tomorrow, your data is still right where you left it.
