Twilio
Twilio grinds through platform-maturity work: RCS error hygiene, WhatsApp usernames, org-level identity APIs
A side-by-side editorial comparison of Shortwave and Mux — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Mux is layering AI video workflows and deeper engagement analytics onto its streaming infrastructure.
Mux is developing along two clear lines. Mux Data is getting richer engagement analytics, heatmaps, hotspots, and custom monitoring dashboards, while Mux Robots, its hosted AI video-workflow layer, has graduated from technical preview to a billed beta. Around both, the platform is adding operational controls like per-environment rate limits, token priority, and usage-export CSVs.
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.
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.
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.
Mux is developing along two clear lines. Mux Data is getting richer engagement analytics, heatmaps, hotspots, and custom monitoring dashboards, while Mux Robots, its hosted AI video-workflow layer, has graduated from technical preview to a billed beta. Around both, the platform is adding operational controls like per-environment rate limits, token priority, and usage-export CSVs.
The through-line is Mux moving beyond raw video encoding and delivery toward an analytics-and-automation platform. Robots turns AI processing into orchestrated, directive-driven workflows over video assets; Data is turning playback telemetry into per-moment engagement insight. The recent operational features (rate limits, usage exports) are the maturity work that lets teams run both at production scale.
Expect Mux Robots to keep hardening toward general availability with more directive and orchestration capability now that it is billed, and Mux Data to keep expanding its engagement API surface.
