Shortwave vs Notion: at a glance
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 Notion?
Notion is turning itself into the place teams and their AI agents share one board.
Notion has moved well past docs-and-databases into an agent platform. Its 3.5 and 3.6 releases stood up a full developer platform — a hosted Workers runtime, a CLI, and an External Agents API — then wired Claude, Cursor, and Codex into shared boards where teammates can @-mention them. AI Meeting Notes with speaker labels, Microsoft file read/write, and Outlook control round out a workspace being rebuilt around agents doing real work.
Shortwave vs Notion: 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.
Notion
6.3PMCOMMS
Notion is turning itself into the place teams and their AI agents share one board.
◆ Current state
Notion has moved well past docs-and-databases into an agent platform. Its 3.5 and 3.6 releases stood up a full developer platform — a hosted Workers runtime, a CLI, and an External Agents API — then wired Claude, Cursor, and Codex into shared boards where teammates can @-mention them. AI Meeting Notes with speaker labels, Microsoft file read/write, and Outlook control round out a workspace being rebuilt around agents doing real work.
◆ Where it's heading
The direction is orchestration: Notion wants to be the surface where human and machine work sit side by side, with agents assignable like teammates and extensible through customer-written Workers. Each recent release deepens that bet — mobile agents, more model choices, new MCP connections, and admin controls for spend and audit. The note-taking product is now the on-ramp, not the point.
◆ Prediction
Expect the External Agents roster to expand beyond Claude, Cursor, and Codex, and Workers to move from free beta to credit-metered billing on the announced August 11, 2026 date.
