Summary

Shortwave is an AI email app for organizing, composing, scheduling and finding messages through prompts. Its tools include inbox splits, bundles, delivery schedules, email todos, summaries, AI filters and AI-assisted search. Teams can share live threads, leave private comments, assign next steps and apply shared labels. Shortwave also connects with apps such as Slack, Calendar, Notion, Asana and HubSpot; its pricing information describes built-in integrations or MCP. The free plan is available, and the listed paid starting price is $30/user/mo with a 14-day trial. Paid plans differ in search history, thread limits and AI filters: Business includes five years of history, searches of up to 50 threads and three filters; Premier and Max offer unlimited history, with limits of 100 and 150 threads per search and 10 and 50 filters, respectively. Shortwave says stored data is encrypted at rest with AES256 and in transit with TLS 1.2+, and customer data is not used to train third-party LLMs. It lists CASA Tier 2 compliance and annual third-party security audits.
