What is Shortwave?
Shortwave keeps folding autonomy into the inbox, one AI action at a time.
Shortwave has moved decisively from an AI-assisted email client to an inbox that acts on the user's behalf. The assistant reads, drafts, organizes, and — via the Tasklet integration — triggers automated workflows across thousands of apps, with its work surfaced inside Shortwave rather than buried in Gmail. Every release since late 2024 has pushed more of the email workflow out of the user's hands and into the model's.
What is Superhuman?
Superhuman is becoming the email layer for AI agents, not just the fastest email client.
Superhuman has reached cross-platform parity with a complete mobile redesign and expanded its AI footprint substantially. Auto Drafts 2.0 now draws from inbox, calendar, and web context to produce drafts that users send unedited 60% of the time. The MCP integration exposes all connected Gmail and Outlook accounts to Claude, ChatGPT, and other agents simultaneously.
Shortwave vs Superhuman: editorial side-by-side
Shortwave
0.0COMMS
Shortwave keeps folding autonomy into the inbox, one AI action at a time.
◆ Current state
Shortwave has moved decisively from an AI-assisted email client to an inbox that acts on the user's behalf. The assistant reads, drafts, organizes, and — via the Tasklet integration — triggers automated workflows across thousands of apps, with its work surfaced inside Shortwave rather than buried in Gmail. Every release since late 2024 has pushed more of the email workflow out of the user's hands and into the model's.
◆ Where it's heading
The direction is a steadily widening action surface: MCP connectors to external tools, AI Memories, voice, and now trigger-based automation all frame email as an agent runtime rather than a reading pane. Model choices track the frontier closely — Claude 3.7 to Sonnet 4 to the 4.6 family — keeping capability tied to whatever the best available model can do. The team ships broadly across web, desktop, iOS, and Android each cycle.
◆ Prediction
The next moves most likely deepen autonomous execution — more trigger types and tighter loops where the assistant acts with less confirmation — rather than adding new surface features.
Superhuman
5.0COMMS
Superhuman is becoming the email layer for AI agents, not just the fastest email client.
◆ Current state
Superhuman has reached cross-platform parity with a complete mobile redesign and expanded its AI footprint substantially. Auto Drafts 2.0 now draws from inbox, calendar, and web context to produce drafts that users send unedited 60% of the time. The MCP integration exposes all connected Gmail and Outlook accounts to Claude, ChatGPT, and other agents simultaneously.
◆ Where it's heading
The product is converging on a model where Superhuman acts as the intelligent intermediary between users and their email — whether the user is driving it directly or delegating to an AI agent. Outlook category support and Gmail label sync for drafts extend this to more of the enterprise email surface. The direction is less about speed and more about AI-augmented inbox ownership.
◆ Prediction
The next move is likely deeper agentic capability: scheduled tasks, autonomous triage, or proactive send — going beyond drafting into taking action without the user in the loop.
