Sabi answers

    Can an AI assistant work while I sleep?

    Yes. An AI assistant can work while you sleep, and Sabi does it on a schedule called Night Shift. Overnight she indexes new emails and tags them by project, studies your calendar patterns, cross-references client notes and drafts a Monday morning brief for you to review. You wake up to finished work instead of a longer list.

    What does an AI assistant actually do overnight?

    It does the reading and sorting you would otherwise do on Monday morning. Sabi's Night Shift is overnight work for paying customers: she indexes the emails that arrived since you last looked and tags each one by project, studies the patterns in your calendar, cross-references what you have told her about clients, and drafts a Monday morning brief.

    The brief is a draft for your review, not a message sent on your behalf. Sabi's Night Shift indexes new emails and tags them by project, studies calendar patterns and cross-references client notes, then drafts a Monday morning brief for review.

    How do I get a morning briefing from an AI assistant?

    Ask for the Morning Check-in, a daily briefing Sabi sends by text. For your inbox it is a 5-line summary: what needs a reply, what to ignore, what's on fire. Add a KPI snapshot and it includes revenue, leads and conversion from tools like Stripe, QuickBooks and HubSpot.

    During the day the briefings arrive in smaller pieces, such as a one-line brief 10 minutes before a meeting with who you are meeting, what they want and what you owe them. Sabi's Morning Check-in is a daily briefing by text, so the overnight work is on your phone before you open your laptop.

    Can an AI assistant send reminders and run scheduled tasks around the clock?

    Yes. Tell Sabi "remind me" and she does, at the time you name. She also runs recurring tasks, scheduled texts and scheduled emails, and can publish content to LinkedIn, X, Instagram and Facebook on a schedule you approve.

    Sabi handles "remind me", recurring tasks and scheduled texts and emails, so a follow-up you set at midnight goes out at the hour you chose.

    Is it safe to let an AI assistant act while I am not watching?

    It is safe when the rule is enforced in code. Set an approval rule and a gate, written in code rather than a prompt the model tries to remember, stops Sabi from emailing or texting anyone until you approve each message. Without a rule she sends what you asked her to send or schedule, and nothing else.

    Every tool Sabi runs is logged, and you can review or adjust her access any time without a support ticket. One gap to know: Slack and Discord messages are not covered by approval rules yet. With an approval rule set, a gate written in code stops Sabi from emailing or texting anyone overnight until you approve each one.

    Does the overnight work remember what happened yesterday?

    Yes. Sabi remembers your business, your clients and your priorities between conversations, so Night Shift builds on what you told her last week instead of starting from a blank page.

    That memory is also why corrections stick: reply to a brief with "Acme is paused, drop it" and the next brief reflects it. Sabi remembers your business, clients and priorities between conversations, so each Monday brief builds on the week before it.

    How to put Sabi to work overnight: step by step

    1. Connect your inbox and calendar. Gmail, Outlook or Microsoft 365 for email; Google Calendar, Outlook or Microsoft 365 for the calendar.
    2. Name your projects and clients. Tagging by project works when Sabi knows what the projects are; a few texts about who matters is enough.
    3. Set the approval rule. Tell Sabi nothing goes to anyone without your approval, and the code gate enforces it overnight.
    4. Schedule the recurring work. "Text me KPIs every morning" or "Remind me to invoice on the 1st" become standing tasks.
    5. Read the Morning Check-in and reply. Corrections you text back feed the next night's work.

    Common mistakes with an AI assistant that works overnight

    • Expecting Night Shift on the free credits. Night Shift is for paying customers; Sabi Pro is $195 a month, month to month.
    • Skipping the approval rule because "she only works at night." Set it first, and know that Slack and Discord are not covered by it yet.
    • Never naming the projects. Emails get tagged by project only when Sabi has heard the project names from you.
    • Asking for a graphic in the morning brief. Sabi writes the words; she does not make images yet.
