S1
A personal AI command center for people who run their work through email, calendar, tasks, contacts, memory, and the rest of their business tools. S1 reads the noise, surfaces what actually matters, and helps you move on it.
Works in the app and by SMS for verified users.
Get started with S1 Sign inWHAT S1 DOES
Five things that show up the day you sign in.
Reply Queue
Finds the emails that actually need a response.
S1 scores your inbox by actionability and timing, then hands you a short list of replies that matter today. The rest stays out of the way.
Morning Brief
A short operating plan for your day.
Calendar, inbox, tasks, and memory pulled into one read. You see what's on the schedule, what's blocking, and what to handle first.
Meeting Prep
Context before the call, not after.
Before each meeting, S1 pulls the relevant emails, prior threads, contact history, and notes so you walk in knowing what's already on the table.
Follow-Up
Surfaces stale commitments and next actions.
S1 watches for replies you owe, promises you made, and threads that have gone quiet. It nudges you on the ones you'd want to remember.
Action Confirmation
You approve before anything is sent.
Risky sends and writes — emails, calendar invites, contact edits — go into an approval queue. S1 drafts; you decide.
THE LOOP
Connect Your Apps
Plug in email, calendar, tasks, contacts, and the business tools you already use.
Ask From Anywhere
Talk to S1 in the app, or by text once your number is verified. Same memory, either way.
S1 Checks Context
It pulls from your connected apps and your saved memory so the answer fits your actual situation.
Reply & Approve
Short answers come right back. Anything that sends or writes waits on your approval first.
USING S1 BY TEXT
S1 also works over SMS for users who verify a phone number from inside the app. Texts are tied to your account and to things you actually did or asked about — verification codes, assistant replies, workflow summaries, reminders, and confirmation prompts for actions you started.
No marketing texts. No cold outreach. SMS opt-in data and consent are not sold or shared.
