Superhuman vs Matrix
Side-by-side trajectory, velocity, and editorial themes.
Superhuman pushes calendar onto mobile and opens the inbox to AI agents via MCP.
Superhuman is a speed-focused email client now building out two fronts at once: calendar features across mobile (Android calendar, multi-day iOS views, share-availability) and an agentic layer that lets external AI tools drive the inbox through MCP and a Codex plugin. The release cadence is high and split between mobile parity and AI access.
Superhuman is turning its mail client into something AI agents can operate, with search, draft, schedule, send, and triage from Claude, ChatGPT, or Codex, while filling mobile gaps to keep parity with desktop. The bet is that being the most automatable inbox matters as much as being the fastest one.
The next likely move is more MCP-driven capability and continued mobile calendar buildout, extending the Codex/Claude/ChatGPT integration and the new Android and iPad calendar surfaces.
Matrix 1.19 lands encrypted room history sharing and custom emoji, clearing a multi-year MSC backlog
Matrix ships a spec release roughly quarterly and reports weekly via This Week in Matrix. The ecosystem is mid-transition to Matrix 2.0, where simplified sliding sync and closing E2EE gaps are the dominant threads. Version 1.19 is the headline event of this window; the rest is community, governance, and ecosystem reporting.
The spec is working through a long-pending MSC backlog: image packs merged, simplified sliding sync accepted, and now encrypted history sharing standardized. Each release chips at features that clients (Element X, FluffyChat, Cinny, Nheko) already shipped ahead of the spec, pulling the ecosystem toward a common Matrix 2.0 baseline.
Expect the E2EE-related sliding-sync extension MSCs to be the next priority, since simplified sliding sync is accepted but won't land in a spec release until enough extensions (several supporting encrypted messaging) are also accepted.
