What is Superhuman?

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.

What is Grain?

Meeting recorder bets on MCP and one-click handoff to Claude and ChatGPT as its primary AI bridge.

Grain is shipping fast across three fronts at once. The newest grab-bag adds meeting-detection notifications, refreshed playlists, and tighter HubSpot sync. A major mid-May release introduced an MCP integration, one-click hand-off of meetings to Claude or ChatGPT, Markdown-formatted transcripts that include participant and prior-context, bulk send-to-AI actions, and Personal API access on the Starter tier. Earlier in the quarter, the desktop app gained a real-time notepad and a redesigned meeting page.

Superhuman vs Grain: editorial side-by-side

S6.3

Inbox becomes an MCP endpoint — agents now drive Superhuman alongside humans, in your voice.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.

Meeting recorder bets on MCP and one-click handoff to Claude and ChatGPT as its primary AI bridge.

◆ Current state

Grain is shipping fast across three fronts at once. The newest grab-bag adds meeting-detection notifications, refreshed playlists, and tighter HubSpot sync. A major mid-May release introduced an MCP integration, one-click hand-off of meetings to Claude or ChatGPT, Markdown-formatted transcripts that include participant and prior-context, bulk send-to-AI actions, and Personal API access on the Starter tier. Earlier in the quarter, the desktop app gained a real-time notepad and a redesigned meeting page.

◆ Where it's heading

Grain is rebuilding itself as the AI-friendly meeting layer rather than a standalone meeting tool. The MCP integration plus the deliberate work on AI-readable transcripts (Markdown, contextual metadata, bulk transport) signal that the product team thinks the user's value is increasingly created inside Claude/ChatGPT, not inside Grain itself. The live-meeting notepad and the API additions point in the same direction — make meeting data easy to extract.

◆ Prediction

Next likely moves are deeper MCP surface area (more action types, write-back into Grain from external agents), agent-driven workflows in HubSpot/Salesforce/Zapier integrations, and continued infrastructure work to make transcripts more queryable.
