The first proactive personal assistant
A quiet assistant for the small back-and-forth of your day.
Leo connects to your Gmail and Google Calendar, reads what’s coming in, and proposes the next move before you ask — a reply, an RSVP, a meeting, a reminder — ready for you to accept with one tap.
What Leo does
Leo is a personal assistant app for Android. When you connect your Google Account, Leo reads your incoming Gmail messages and Google Calendar events to do two things: give you a short morning brief — your schedule, your tasks, and the emails actually worth a reply — and turn actionable emails into one-tap action cards: reply to a message, RSVP to an invitation, schedule a meeting, surface a bill to pay, or add a task.
You stay in control of everything. Leo only acts when you approve a card, it reads your mail but never edits, labels, or deletes it, and you can disconnect Google access at any time from Settings. Before Leo uses AI to draft anything, the personal details in your email are redacted. Exactly what Google data Leo uses, how it’s processed, and how to delete it are described in our Privacy Policy.
A day with Leo
Your day, planned.
Every morning, before you reach for your phone.
Leo opens your day with the weather, your meetings, and the few emails actually worth a reply — one quiet message, before the inbox swallows the morning.
Leo · Tuesday, 7:02 AM
Good morning. Here’s your day.
- · 68° and sunny.
- · Mia’s dentist at 10:30, school pickup at 3.
- · Two emails worth a look — Kate about Sunday brunch, vet about Buddy’s checkup.
Your emails, drafted.
An email lands that actually needs you.
Leo reads it, recognizes what it’s asking, and drafts your reply in plain language. Tap Send when you’ve skimmed it — or Edit if you’d rather phrase it your way.

Jess is asking if you’re free for dinner Saturday.
“Yes — let’s do Sushi Roku at 7. See you then.”
Your messages, replied.
A text from your sister lands while you’re getting dinner started.
Leo reads it, drafts a quick reply, and waits for you to tap Send. Same flow for SMS or WhatsApp — no switching apps, no losing your train of thought.

Sara: “What time does Sophie’s party start?”
“2:00 PM at Oak Park — let me know if you need a ride.”
Your invites, sorted.
Two things at the same time this Saturday.
Leo flags the conflict, shows both, and lets you RSVP without ever opening Calendar.

Sophie’s 5th birthday party — Sat 2:00 PM at the park.
Heads up: collides with Mia’s dentist appt at the same time.
Your lists, captured.
You think of milk while walking the dog.
Tell Leo to add it and it lands on your Groceries tab. Tasks works the same way on its own tab — bulk-dictate a comma list, or accept items Leo extracts from inbound email and SMS.

Promises, remembered.
You promised to send those photos this weekend.
Leo remembers what you promised — and when the time comes, it nudges you and offers to draft the message itself.
Leo · Sunday, 10:00 AM
You said you’d send Mom the photos from your trip this weekend. Want me to draft it?
One sentence, triggers many moves.
You tap the mic: “I’m running fifteen minutes late.”
One sentence drives several quiet moves at once — the text drafted to whoever you’re meeting, your next appointment shifted to match. Each one its own card to accept.
