Shortwave

Agentic AI email that organises, writes, searches and schedules from a prompt

Overview
Shortwave pairs a modern inbox with an AI assistant that can organise mail, write and enhance drafts, search across threads and schedule calendar events from a plain prompt. Team features such as shared threads, comments, assignments and shared labels sit alongside the AI. AI limits scale by plan, with caps on threads per AI search and on AI filters, so heavy users end up on the higher tiers, and it is an email-first tool rather than a general chief of staff.
Our verdict
A fast, capable AI inbox with honest public pricing. Check the plan limits against your daily volume before committing.
Best for
