Shortwave
What it is
Shortwave is an AI email app for organizing, writing, scheduling, and searching email with prompts. It offers inbox splits, bundles, delivery schedules, email todos, summaries, AI filters, and AI-assisted search. Teams can share live email threads, add private comments, assign next steps, and use shared labels. Shortwave can connect with apps such as Slack, Calendar, Notion, Asana, and HubSpot; its pricing page also describes built-in integrations or MCP. It is available on Android, iOS, macOS, web, and Windows, with a free plan and a 14-day trial. Paid plans start at $30/user/mo. Business includes five years of AI search history, up to 50 threads per search, and three AI filters. Premier and Max include unlimited search history, with limits of 100 and 150 threads per search and 10 and 50 AI 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.
