A chief of staff does not answer questions. They watch everything, decide what needs you, prepare the answer and bring it to you. Momo does that for your Gmail and Google Calendar.

## What an AI chief of staff does

An AI assistant waits to be asked. An AI chief of staff speaks first. The difference is proactivity: it reads your inbox and calendar on a schedule, ranks what matters, prepares the work, and brings you a short list of decisions.

Momo runs that loop every day.

- Morning brief by email: who needs a reply, who owes you one, what you promised, today's meetings with prep notes from the last thread with the first attendee.
- Ready drafts: every item in the brief that needs a reply arrives with one already written in your voice, saved in Gmail Drafts.
- Follow-ups: threads you sent that went quiet get a nudge offered after the number of days you set.
- Promises: commitments in both directions, found in email and auto-closed when delivered.
- Scheduling: free slots offered over email and booked when the other person picks one.
- Meeting prep notification 15 minutes before each call, with your last email to that person and anything still open.

## How it is different from an AI assistant or an email client

Chat assistants like ChatGPT and Gemini are reactive and do not know your inbox. Email clients like Superhuman and Shortwave speed up the time you spend in email, but you still do the work. Calendar optimisers like Motion and Reclaim move blocks around on your calendar but do not talk to the people in your inbox.

Momo sits in between: it reads Gmail and Google Calendar, does the preparation, and asks before anything leaves.

## Can an AI chief of staff replace a human one?

Not the judgement, the relationships or the hard conversations. It replaces the part that is tracking: who is waiting, what was promised, what is due, what is on tomorrow. For a founder, a sales lead or a recruiter without a human assistant, that is most of the drag.

Momo is also explicit about what it will not do: it will not send email, cancel a meeting, or commit you to a deadline on its own. It drafts and you decide.

## What it costs

Momo is free during early access. A Pro plan at ₹499 per month is planned, far below a human assistant and below most US-priced email tools.
