Shortwave

Originally launched as a team email tool, Shortwave has evolved into a comprehensive AI email assistant that combines a deeply personal writing AI, automated inbox organization, and an agentic automation platform within a single Gmail-connected interface.

The platform's design philosophy centers on Inbox Zero as a daily achievable state rather than an aspirational goal, with AI doing the organizational and routine communication work that typically consumes hours of knowledge worker time.

Shortwave's Ghostwriter is one of its most distinctive capabilities: an AI writing assistant that learns the individual user's personal voice, phrasing patterns, and communication style over time.

Unlike generic AI email writers that produce recognizably template-like output, Ghostwriter improves its accuracy to the user's voice with each correction and feedback signal, eventually drafting emails that colleagues cannot easily distinguish from manually written messages.

This progressive learning model makes Ghostwriter increasingly valuable the longer a user works with it, with the AI's drafts requiring progressively less editing as it calibrates to each person's specific communication style.

Shortwave's Splits feature divides the single Gmail inbox into multiple focused priority streams, allowing users to create dedicated views for categories like important personal email, newsletters, notifications, and team messages.

Smart labels auto-apply to incoming email automatically based on AI classification, ensuring new messages appear in the correct stream without manual sorting.
