Subsplash vs Superhuman

Side-by-side trajectory, velocity, and editorial themes.

S3.8

Subsplash wires natural-language AI through People and Analytics — its two highest-leverage surfaces.

◆ Current state

Subsplash has spent the last two months putting AI on the busiest parts of its admin. Trends AI consolidated giving, attendance, and events data into AI-buildable dashboards in late March, and People Assistant followed in May with natural-language filtering of congregation lists. Between those, the team shipped a dedicated Events Manager role, a group-attendance analytics dashboard, and smaller workflow-board UX gains.

◆ Where it's heading

The bet is clear: ministry staff with no SQL or BI background want to ask questions of their congregation's data in plain language — both for analysis and for action. Trends AI handles the analytical half; People Assistant is the actionable list-building counterpart. The supporting work — RBAC, attendance analytics, faster workflow navigation — is what lets the AI features actually land inside real church-staff workflows.

◆ Prediction

Expect AI to extend next into Workflows (plain-language routing rules for congregants) and Giving (donor segmentation for stewardship outreach), with a unified AI surface across modules as the natural endpoint. Pricing the AI tier separately, as Trends AI already is, telegraphs how Subsplash will monetize this push.

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.
