Subsplash vs Slack
Side-by-side trajectory, velocity, and editorial themes.
Subsplash wires natural-language AI through People and Analytics — its two highest-leverage surfaces.
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.
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.
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.
Slack's developer platform is reorganizing around agents, MCP, and streaming Block Kit surfaces.
Slack's platform work over the past quarter centers on agent development and richer app surfaces. The CLI 4.x line ships agent scaffolding, the Slack MCP server keeps gaining tools, and Block Kit has added streaming APIs plus new block types (cards, carousels, data tables). Security plumbing like PKCE and optional OAuth scopes rounds out a platform being hardened for third-party AI apps.
The direction is to make Slack the surface where AI agents are built, deployed, and rendered. Streaming APIs and new Block Kit blocks exist to host conversational and agent UIs natively, while the MCP server turns Slack into an addressable tool for external agents. Expect continued cadence on both the developer tooling and the runtime surface.
Next likely moves are more MCP server tools and additional streaming-oriented Block Kit components as the agent-app surface matures.
