Shortwave vs Matrix
Side-by-side trajectory, velocity, and editorial themes.
Shortwave keeps folding autonomy into the inbox, one AI action at a time.
Shortwave has moved decisively from an AI-assisted email client to an inbox that acts on the user's behalf. The assistant reads, drafts, organizes, and — via the Tasklet integration — triggers automated workflows across thousands of apps, with its work surfaced inside Shortwave rather than buried in Gmail. Every release since late 2024 has pushed more of the email workflow out of the user's hands and into the model's.
The direction is a steadily widening action surface: MCP connectors to external tools, AI Memories, voice, and now trigger-based automation all frame email as an agent runtime rather than a reading pane. Model choices track the frontier closely — Claude 3.7 to Sonnet 4 to the 4.6 family — keeping capability tied to whatever the best available model can do. The team ships broadly across web, desktop, iOS, and Android each cycle.
The next moves most likely deepen autonomous execution — more trigger types and tighter loops where the assistant acts with less confirmation — rather than adding new surface features.
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.
