What is Subsplash?
Subsplash is layering AI analytics across its church-operations platform.
Subsplash runs giving, people, events, and media for churches, and it has spent recent releases adding an AI layer on top: Trends AI for analytics and an AI People Assistant for natural-language filtering. The cadence pairs these with steady operational features like event roles, attendance analytics, and workflow navigation.
What is Slack?
Slack is quietly rebuilding itself as a runtime for third-party agents.
Slack's developer platform has shifted its center of gravity from bots-that-reply to agents-that-act. The last month is dominated by agent primitives: apps can now receive the context a user is looking at, Slackbot can call external tools over MCP, and a dedicated agent messaging surface ships alongside steady CLI and Block Kit work.
Subsplash vs Slack: editorial side-by-side
Subsplash
2.5COMMS
Subsplash is layering AI analytics across its church-operations platform.
◆ Current state
Subsplash runs giving, people, events, and media for churches, and it has spent recent releases adding an AI layer on top: Trends AI for analytics and an AI People Assistant for natural-language filtering. The cadence pairs these with steady operational features like event roles, attendance analytics, and workflow navigation.
◆ Where it's heading
Subsplash is consolidating its scattered ministry data (giving, attendance, groups, now media and campaigns) into AI-driven dashboards, and making that data queryable in plain language. The direction is turning an operations suite into a decision tool, with AI as the interface rather than a separate product.
◆ Prediction
The next likely move is extending Trends AI to more data sources or pushing the natural-language interface deeper into other modules, following the People Assistant and media/campaign additions.
Slack
7.5COMMSCOLLAB
Slack is quietly rebuilding itself as a runtime for third-party agents.
◆ Current state
Slack's developer platform has shifted its center of gravity from bots-that-reply to agents-that-act. The last month is dominated by agent primitives: apps can now receive the context a user is looking at, Slackbot can call external tools over MCP, and a dedicated agent messaging surface ships alongside steady CLI and Block Kit work.
◆ Where it's heading
Each release fills in a piece of an agent platform — context in, tools out, and a native place for agents to converse. Block Kit is gaining richer primitives (containers, data visualization) that read as the display layer for agent output. Three CLI releases in a month show the tooling keeping pace with the expanding surface.
◆ Prediction
Expect the next moves to connect these pieces: agent context feeding MCP tool calls, and Block Kit's new blocks becoming the standard way agents render results in-channel.
