Shortwave vs Bandwidth
A side-by-side editorial comparison of Shortwave and Bandwidth — release velocity, themes, recent moves, and the top alternatives to consider.
Shortwave vs Bandwidth: 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 Bandwidth?
Bandwidth ships Identity Presentation (branded calling) in beta — trust layer for enterprise outbound calling.
Bandwidth is an enterprise communications API provider actively shipping across messaging, voice, and number management. The last 30 days include SIP trunking on Build, 10DLC registration in the app UI, RCS test number self-serve, and voice debug logs in Voice Insights. Identity Presentation — authenticated branded calling that displays the caller's brand name, logo, and call reason on mobile phones — entered beta on August 14 and is the most differentiated new capability.

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.
Bandwidth
6.3COMMS
Bandwidth ships Identity Presentation (branded calling) in beta — trust layer for enterprise outbound calling.
◆ Current state
Bandwidth is an enterprise communications API provider actively shipping across messaging, voice, and number management. The last 30 days include SIP trunking on Build, 10DLC registration in the app UI, RCS test number self-serve, and voice debug logs in Voice Insights. Identity Presentation — authenticated branded calling that displays the caller's brand name, logo, and call reason on mobile phones — entered beta on August 14 and is the most differentiated new capability.
◆ Where it's heading
The platform is advancing on two simultaneous tracks: developer experience (self-serve tooling replacing support tickets, debug visibility, UI for previously API-only workflows) and differentiated enterprise capabilities (branded calling, RCS agent testing, MOS voice quality monitoring). The Brazil PSTN replacement expansion shows the geographic build-out is ongoing. Each release reduces friction at a specific operator task.
◆ Prediction
Identity Presentation moving from beta to general availability is the most likely near-term announcement. RCS expansion to additional carriers or geographies is the second active investment, given the self-serve test number tooling that just shipped.
