Shortwave vs. RevoAI

Shortwave is the smartest email app on planet Earth. Email is the backbone of modern business communications. Every day, billions of emails are exchanged inside and between businesses discussing everything from investment decisions, to high-stakes negotiations, to product designs, to major purchases. Email is the one tool that connects everyone — employees, customers, vendors, even the CEO. The biggest decisions are made in the email inboxes of business leaders. And yet, the inbox you rely on every day has not fundamentally improved in over a decade.

Revo is an AI email assistant that drafts replies directly inside Gmail and Outlook before the user opens the email. It pulls context from connected business tools rather than relying on email history alone. When an email arrives, Revo reads the thread and cross-references information from Slack conversations, meeting notes, CRM records, project tickets, and documents to generate a fact-based draft. Each draft includes a source citation showing which tools and data points were used to write it.
