Shortwave

Shortwave is an AI-powered and agentic email client built specifically for Gmail and Google Workspace accounts. It was created by former Google engineers who worked on Google Inbox and is designed to turn a traditional email inbox into an organized, task-focused workspace. Shortwave works on top of the Gmail API, so users do not need to replace their email address or migrate their existing mailbox. It uses AI to understand email conversations, search historical messages, organize incoming mail, and help users write responses based on their email history.

How Shortwave Works

• Gmail Integration: Shortwave connects to your Gmail account through the Gmail API instead of replacing your existing email address or requiring a separate email migration.
• Semantic Indexing: It syncs your mailbox and builds a secure vector index of email messages, history, and attachments so the AI can understand and search information across your inbox.
• AI Reasoning: When you ask a question or search your inbox, Shortwave's AI assistant uses large language models such as Claude and GPT-4 to analyze email history, synthesize information, and create context-based responses.
• Structured Triage: Shortwave groups similar low-priority emails together while separating important conversations. This allows users to process groups of emails at once instead of handling every message individually.

How We Rated Shortwave

We rated Shortwave based on its AI email capabilities, search and reasoning features, inbox organization, writing assistance, task management, collaboration tools, and overall ease of use. We also considered how well its AI works with email history and attachments and how effectively its Smart Bundles and Tasklets support everyday inbox management. Pricing, free-plan limitations, platform compatibility, search history, AI usage limits, and the learning curve were also considered. The rating reflects how practical Shortwave is for Gmail users, professionals, and teams looking for an AI-focused email management tool.
