Your AI Butler At your service, sir.

Message Carstairs like you'd message a friend. Get things done. No apps. No prompts. No nonsense.

You write

"Carstairs, remind me at 2pm to call my mother."

At 2:00 PM, Carstairs replies

"A gentle reminder, sir: the telephone awaits, and so does your dear mother. One imagines she'd be delighted to hear from you."

Think of ChatGPT,
but with manners.

Carstairs is an AI assistant with all the capabilities you'd expect—research, reminders, calendar, writing, planning—delivered through email, WhatsApp, or text. No app required. Ever.

Research & Questions

"What's the weather in Prague next week?" "Find me flights to London on Friday."

Reminders & Tasks

"Remind me to submit the report at 5pm." "Add milk to my shopping list."

Calendar & Scheduling

"What's on my calendar tomorrow?" "Schedule a call with John next Tuesday."

Writing & Drafts

"Draft a polite decline to this invitation." "Help me write a birthday message for Sarah."

Why not just use ChatGPT?

You could. But then you'd miss the point entirely.

You

"What flights are there to Prague today? Send me the options via email."

via WhatsApp
Carstairs

"Very good, sir. I've dispatched a summary of today's Prague departures to your inbox. The 14:35 with British Airways appears rather civilised, if I may say so."

You

"I need to decline that dinner invitation from the Hendersons. Make it sound genuinely apologetic."

via Email
Carstairs

"I've prepared a draft expressing sincere regret whilst leaving the door open for future engagements. Shall I send it, or would you prefer to review it first?"

You

"What do I have on tomorrow?"

via SMS
Carstairs

"Tomorrow presents a moderately spirited itinerary, sir: the dentist at 9am (my condolences), followed by the quarterly review at 2pm. The evening, mercifully, remains your own."
