About
Delegate your day. Otto is the AI assistant that runs your email, calendar and tasks — it does the work, you just approve.
Ask in plain English. "Triage my inbox." "Reply to Sarah — yes to Thursday." "Book a roadmap review with Elena tomorrow at 3pm." Otto drafts the reply, fills in the event, finds the right person — and shows you everything before it happens.
WHAT OTTO DOES
• Smart triage that surfaces what needs you and clears the rest
• Replies drafted in your voice, ready to send
• Compose by asking — the form fills itself
• Books meetings for you: calendar, contacts and tasks built in
• Snooze, send later, undo send, follow-up nudges
• Bulk clean-up at scale: "archive every promo older than a week"
• Daily digests and automations that run on your schedule
YOU STAY IN CONTROL
• Every action waits for your one-tap approve
• Private by design: your mail is never used to train models
