Serif
AI executive assistant that automates inbox sorting, drafting replies, and calendar scheduling.
What is Serif?
Serif is an AI executive assistant designed to automatically organize inboxes, draft replies, and manage scheduling to save hours on email management. Operating as an intelligent serif email partner for professionals and teams, it seamlessly pre-writes replies for emails needing a response, eliminates tedious back-and-forth communication, and filters away junk. Beyond its core AI email assistant functionality, the platform serves as a hub for productivity by offering versatile features like a built-in email generator, a reliable follow-up email creator, a professional subject line generator, and a handy email signature builder. While primarily an executive tool, the platform is also known for hosting unique, complimentary tools such as a random gmail generator, a temp gmail option, a Google account generator, and a custom Gmail generator that utilizes the classic gmail dot trick (also known as the gmail dot variations generator or freegmail helper) to create multiple alias options from a single inbox.
