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.
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.

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.
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.
