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 Twilio?

Twilio's voice AI stops cutting callers off mid-sentence, using its own turn-taking model.

Twilio shipped a dense batch on November 11 to 13. Smart Turn Detection for Conversation Relay is now generally available: an in-house model judges from meaning, not silence, when a caller has finished speaking. Alongside it come US Branded Calling across T-Mobile, Verizon and AT&T from one registration and Apple Business Invitations, both in private beta, plus Email Logs filters and search and more specific A2P 10DLC rejection codes from December 9.

Shortwave vs Twilio: editorial side-by-side

S0.0

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.

6.3

Twilio's voice AI stops cutting callers off mid-sentence, using its own turn-taking model.

◆ Current state

Twilio shipped a dense batch on November 11 to 13. Smart Turn Detection for Conversation Relay is now generally available: an in-house model judges from meaning, not silence, when a caller has finished speaking. Alongside it come US Branded Calling across T-Mobile, Verizon and AT&T from one registration and Apple Business Invitations, both in private beta, plus Email Logs filters and search and more specific A2P 10DLC rejection codes from December 9.

◆ Where it's heading

Two threads run in parallel: trust and identity at the carrier and channel level (branded calling, Apple invitations, 10DLC feedback, STIR/SHAKEN status) and a voice AI stack where Twilio now ships its own models instead of only relaying third-party ones. Email keeps getting operator tooling around deliverability.

◆ Prediction

Expect more of Conversation Relay to move to Twilio-built models and settings, and the branded calling and Apple invitation betas to widen in the coming months, as earlier private betas here have.
