You Need a 24/7 Executive Assistant

You're not just busy, you're mentally overloaded. Every day, countless emails, urgent meetings, critical follow-ups, and unexpected tasks pile up, creating a constant mental burden. Keeping track of it all drains your energy and distracts you from focusing on your zone of genius.

You've heard an executive assistant can transform your life, but finding someone and training them to handle your work takes months. You need help now.

Serif changes that.

Serif is the first executive assistant you can hire instantly, is available 24/7, and trains itself to handle work exactly like you do. It integrates seamlessly into your life, identifies tasks you shouldn't be doing, and handles them completely — so you can focus on your zone of genius.

Here's why Serif is unlike any assistants before it, human or AI:

Seamlessly Integrated Into Your Life

Serif operates directly within the tools you already use every day, like email and calendar, eliminating the need to constantly switch platforms and copy-paste text. And unlike chat-based assistants that don't take actions, Serif can monitor, sort, and draft emails exactly as a human assistant would.

Knows Exactly How You Want Tasks Done

No matter how powerful AI agents are, they don't know how you want things done. Serif is different. It learns your unique communication style, priorities, and preferences,even down to the smallest details like how you format emails and signatures. The result? Every message and task is completed exactly the way you would have done it yourself.

Automatically Identifies Tasks to Handle

Unlike most AI tools that require you to figure out what to delegate, Serif proactively identifies tasks you shouldn't be doing. It analyzes your inbox and calendar, spots repetitive work and administrative tasks, and automatically offers to handle them for you. No more wondering what AI can help with, Serif finds the opportunities for you.

Capable of Handling Long-Horizon Tasks

Most AI agents are designed to handle immediate, short-term tasks which mean you still need to remember to follow up with clients every week. On the other hand, Serif is designed to handle ultra long-horizon tasks that span multiple weeks and even months. This is why Serif can handle tasks like "follow up next quarter when they finish raising capital" where other AI agents would fail.

Reliable and Pressure Tested in Real-Life

Even occasional failures by AI tools can force you into double-checking everything yourself, defeating the purpose of handing off tasks. To ensure Serif is reliable, we tested and refined it rigorously with thousands of real professionals, catching every edge case. If Serif ever encounters uncertainty, it proactively asks for clarification rather than risking errors. Reliability isn't just promised, it's built-in.

The mental load of managing endless tasks is holding you back from your most important work. Serif isn't just another AI tool — it's the executive assistant you've always needed, available instantly and designed to work exactly like you do.

Stop letting administrative work drain your energy. Let Serif handle what it should, so you can focus on what only you can do.
