Serif

Overview

Serif is an AI-powered email assistant designed to eliminate the burden of inbox overload. Instead of adding another tool to your stack, Serif works directly within your existing Gmail or Outlook environment, connecting in one click and immediately learning from your past sent emails. It starts by drafting context-aware replies that you can review, edit, and approve — building trust before you hand over more control.

At its core, Serif combines LLM-based language understanding with your personal communication history. It recognizes recurring questions, identifies high-value or unusual messages, and separates routine requests from those that require a human decision. Once you are comfortable with its output, you can enable autopilot for low-risk scenarios — such as order status, shipping questions, or common support requests — while the system continues to escalate anything involving refunds over a threshold, unusual exceptions, or other sensitive matters for your approval.

Serif is built for teams and individuals who receive high volumes of email across multiple shared inboxes. With support for dedicated addresses like info@, support@, billing@, reception@, accounting@, and quotes@, Serif sorts incoming messages, routes them to the right person or department, and drafts replies in the customer's own language. It is SOC 2 compliant and backed by deployment metrics showing 11M+ emails processed monthly, 611,000+ emails sent monthly, and 150,000+ hours saved monthly.

The value proposition is straightforward: you do not need another email tool — you need an extra hand. Serif acts as that hand, handling repetitive threads, chasing invoices, answering common questions, and surfacing only what genuinely requires your attention. From startups and brokerages to healthcare teams and virtual assistants, Serif helps organizations maintain fast, consistent, and professional email communication without the manual effort.
