What is Signal Desktop?
Signal is quietly rebuilding group governance while polls and pins push into everyday chats
The desktop beta line is shipping a steady run of user-facing social features: polls extended to one-to-one chats, admin deletion of recent group messages, an explicit End Group action, disappearing call events, and reorderable sticker packs. Each release carries one or two concrete changes rather than a bundle. Pinned chats also moved from 4 to 10.
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.
Signal Desktop vs Superhuman: editorial side-by-side
Signal Desktop
5.0COMMS
Signal is quietly rebuilding group governance while polls and pins push into everyday chats
◆ Current state
The desktop beta line is shipping a steady run of user-facing social features: polls extended to one-to-one chats, admin deletion of recent group messages, an explicit End Group action, disappearing call events, and reorderable sticker packs. Each release carries one or two concrete changes rather than a bundle. Pinned chats also moved from 4 to 10.
◆ Where it's heading
Two threads run through the window. One is group administration — admins gained message deletion and a way to formally close a group, turning groups from open-ended threads into objects with a lifecycle. The other is bringing lightweight social mechanics from group chats down into individual ones. Both extend the surface without touching Signal's privacy model.
◆ Prediction
Expect the group-lifecycle work to continue with more admin controls, and for the features currently landing in desktop beta to promote into the stable line on the same weekly-to-biweekly rhythm.
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.
