What happened to Serif?
discontinued The registry marked Serif discontinued on 2026-09-01: its check failed three consecutive times. Last successful sync: 2026-08-20.
Serif is an AI executive assistant designed to help individuals and teams save hours on email, scheduling, and other administrative tasks. It automates email management by drafting replies, organizing inboxes, sending follow-ups, and scheduling meetings. It aims to cut email time by 50% with a simple, one-click operation, requiring no learning curve. Serif also handles complex back-and-forth conversations by taking over tasks when an email is forwarded to it. It is built with a focus on security and privacy, being verified by a Google designated third-party security auditor and working towards SOC 2 Type 2, GDPR, and HIPAA compliance, ensuring user emails are never used to train general AI models.

How this was decided
Not an editorial call. Serif's check failed three syncs in a
row, and the 3-miss rule marks it
discontinued automatically. If the vendor page comes back, the
registry restores it on its own: warn first, then
active. Both directions are recorded as events.
