What is Subsplash?
Subsplash is wiring automation and AI through the church admin stack it already owned
Workflows came out of beta in mid-July with per-step email automation, then immediately gained completion notifications for team leaders. Around it, the administrative surfaces are being rebuilt in sequence: Transfers and reconciliation now tracks who reconciled what and when, Groups gained member limits with a Full badge and finder filters, and event managers can register guests and waive payments directly from the dashboard. The AI line is filling in too — Trends AI added media and campaign data on top of giving, people, attendance and groups, following the natural-language People Assistant in May.
What is Superhuman?
Superhuman is rebuilding around the assistant: pre-drafted replies and multi-account MCP.
Superhuman ships small and often, and its releases now split cleanly in two. One half is conventional client work — calendar on Android, multi-day views on iPhone and iPad, personalized availability sharing. The other is an aggressive agent surface: Auto Drafts 2.0 pre-drafts a reply to every message that needs one, and the Mail MCP now drives multiple Gmail and Outlook accounts from Claude, ChatGPT and Codex.

◆ Current state
Workflows came out of beta in mid-July with per-step email automation, then immediately gained completion notifications for team leaders. Around it, the administrative surfaces are being rebuilt in sequence: Transfers and reconciliation now tracks who reconciled what and when, Groups gained member limits with a Full badge and finder filters, and event managers can register guests and waive payments directly from the dashboard. The AI line is filling in too — Trends AI added media and campaign data on top of giving, people, attendance and groups, following the natural-language People Assistant in May.
◆ Where it's heading
Two threads run in parallel and are starting to meet. One is turning manual church-admin chores into configured automation — workflows that send their own emails, notify on completion, and enforce group capacity without a staff member watching. The other is putting a natural-language layer over an increasingly complete data set, which only becomes useful once giving, attendance, media and campaigns all live in the same place. Recent releases have been closing the gaps in that data set.
◆ Prediction
The obvious convergence is Workflows becoming triggerable from the data — a Trends AI segment or People Assistant query that drops matching people onto a workflow board automatically. Reconciliation gaining an export or accounting-package integration is the other near-term candidate given how much structure was just added to Transfers.
Superhuman
7.5COMMS
Superhuman is rebuilding around the assistant: pre-drafted replies and multi-account MCP.
◆ Current state
Superhuman ships small and often, and its releases now split cleanly in two. One half is conventional client work — calendar on Android, multi-day views on iPhone and iPad, personalized availability sharing. The other is an aggressive agent surface: Auto Drafts 2.0 pre-drafts a reply to every message that needs one, and the Mail MCP now drives multiple Gmail and Outlook accounts from Claude, ChatGPT and Codex.
◆ Where it's heading
The centre of gravity is moving off Superhuman's own client. Each recent release makes the mailbox more usable from somewhere else — first a Codex plugin with prebuilt workflows, then parallel search across every connected account — while in-app work is mostly mobile parity. Superhuman is positioning as the mail layer assistants call, and it names the single-account limit of the first-party Gmail and Outlook connectors as the reason to switch.
◆ Prediction
Expect the MCP surface to keep absorbing the features that only the client could do — Split Inbox triage, Read Statuses, Smart Send are already listed — with the native apps continuing to trail on platform parity.
