Superhuman vs Twilio
Side-by-side trajectory, velocity, and editorial themes.
Inbox becomes an MCP endpoint — agents now drive Superhuman alongside humans, in your voice.
Superhuman ships at very high cadence, mixing mobile polish (Quick Reply from notifications, calendar widget, Split Inbox reorder/hide) with category-shifting AI work. The April MCP launch turned Superhuman Mail into a callable surface for Claude, ChatGPT, and other assistants, with 'uniquely Superhuman' actions (Smart Send, Read Statuses, Split Inbox triage) exposed as tools. Draft Sync with Gmail/Outlook bridges the agent ecosystem further: assistants can draft anywhere, you review and send in Superhuman.
The product is moving from 'fast email for power users' to 'AI-and-humans share the inbox.' Personalization, Write with Voice, and MCP form a clear stack — voice in, agent action, voice out — with the original power-user keyboard-shortcut audience preserved through continued Split Inbox refinement. Mobile gets weekly polish to keep that surface from rotting while the AI direction takes the headlines.
Next likely move is delegated-inbox MCP actions for executive assistants (act-as-on-behalf permissions) and recurring agent tasks tied to Personalization rules. A cross-app demo — Superhuman + Granola + a calendar tool, all via MCP — is the obvious narrative the May 21st virtual event has been set up to deliver.
Twilio reframes itself as the conversation layer for AI agents, not just a messaging API.
Twilio just shipped a coordinated batch of GA launches anchored on a new Conversations layer: Agent Connect SDK, Conversation Memory, Conversation Intelligence, Enterprise Knowledge, and Conversation Relay Insights all moved to GA on the same day. Alongside that, Apple Messages for Business is in private beta and a Bulk Messaging API is in public beta. The platform's center of gravity has clearly shifted from raw channel APIs to an AI-agent orchestration stack sitting on top of them.
Twilio is repositioning the company as the runtime where customer-facing AI agents live — owning memory, intelligence, channel reach, and observability, not just message delivery. The packaging is deliberate: each piece is shippable alone, but together they form an opinionated stack that competes head-on with Salesforce/Genesys agent platforms and with developer-first stacks like LiveKit. Expect Twilio to push hard on lock-in through Conversation Orchestrator as the binding layer.
Next likely moves: GA for Apple Messages for Business, and an expansion of the Agent Connect SDK toward third-party LLM and tool integrations to position it as the de-facto agent runtime on top of Twilio's channels. A Bulk Messaging GA and pricing for the AI features should follow within one to two quarters.
