Shortwave is a modern email client that deeply integrates AI to transform how users manage their inbox. Built on top of Gmail, it offers AI-powered features like email summarization, smart search using natural language queries, and an AI assistant that can draft replies and compose emails based on context. The interface is clean and well-organized, with bundle grouping that keeps your inbox manageable. Its AI writing capabilities are genuinely useful " drafts feel contextually aware and rarely need heavy editing. The freemium model lets users test core features before committing, and the $7/mo entry point is reasonable for the productivity gains. Strengths include excellent Gmail integration, fast performance, and a polished UX that rivals Superhuman at a lower price point. Limitations include being restricted to Gmail accounts only, which excludes Outlook and other providers. Some advanced AI features are locked behind paid tiers. Overall, Shortwave is a compelling choice for Gmail users seeking an AI-enhanced email experience that goes beyond basic writing assistance.
