Overview

Serif is an AI email assistant that sits inside Gmail or Outlook and helps handle the work created by your inbox. It drafts replies, triages incoming messages, and can take over routine conversations such as customer questions, document collection, quotes, and invoice follow-ups.

The product is positioned as an “AI employee” for email rather than a drafting helper. The site describes a guided setup, support for personal and shared inboxes, and a workflow that starts with draft review before moving to more autonomous handling for low-risk jobs or dedicated addresses.

Core capabilities

Works in your existing inbox

Connects to Gmail or Outlook in one click and works inside the inbox you already use, so teams do not need a separate app or new workflow.

Drafts and triages email

Reads incoming messages and drafts replies based on past email history, then lets you approve or edit before sending when you want human review.

Handles routine inbox work

Can answer common questions, collect paperwork, chase invoices, send quotes, and handle other repeat email jobs that usually sit in a shared inbox.

Escalates when needed

Supports workflow handoff from draft-only mode to autopilot for lower-risk scenarios, while escalating unusual or sensitive messages back to a person.

Runs multi-step processes

Can collect documents end to end, create a checklist of missing items, follow up until the packet is complete, and take actions in connected tools such as refunds or file uploads.

Learns your writing style

Learns your tone over time, including phrasing, length, greetings, and sign-offs, so replies can match how you normally write.

Common use cases

Customer support inbox
Use Serif to answer repetitive customer questions, draft replies in your voice, and escalate only the unusual messages that need judgment.
Shared inbox management
Use it for shared team addresses like info@, support@, or billing@ where incoming messages need routing, follow-up, and clear ownership without leaving email.
Document collection and intake
Use Serif to request missing forms, chase signatures or policy documents, and keep a multi-step packet moving until it is complete.
Quotes and billing follow-up
Use it to draft and send quotes, follow up on unpaid invoices, and keep pricing or payment conversations moving without manual chasing.
Operational email workflows
Use Serif to run recurring inbox processes that involve looking up records, matching a message to stored information, and responding with the right details.
