Session vs Superhuman
Side-by-side trajectory, velocity, and editorial themes.
Session shipped a protocol rewrite and a paid tier, then went publicly broke — the founder is asking users to bail it out.
Session is simultaneously in its most ambitious technical phase and an open funding crisis. Protocol V2 — re-implementing forward secrecy and layering post-quantum cryptography on top of Session's onion-routed transport — has been announced, and the Session Pro paid tier exited beta planning into a December development update. Then in March, cofounder Chris McCabe published a personal appeal saying the project cannot continue developing without user support, and the public feed has been quiet since.
The product roadmap that was meant to fund itself via Session Pro is colliding with the underlying problem the appeal makes plain: the Loki/Oxen-era token economics and donations aren't covering ongoing development. Protocol V2 and Pro are the bets that have to land for Session to remain viable; if Pro doesn't convert a meaningful share of the user base, the next twelve months are about scope reduction, not feature growth. The Feb 1 APT key rotation in January suggests the core infrastructure is still being maintained — for now.
Watch for either a hard Session Pro launch and conversion announcement, or a more explicit wind-down / handoff post. A long stretch of silence after a funding appeal usually resolves one way or the other within a quarter; the absence of any new posts since mid-March is itself a signal.
Inbox becomes an MCP endpoint — agents now drive Superhuman alongside humans, in your voice.
Superhuman ships at very high cadence, mixing mobile polish (Quick Reply from notifications, calendar widget, Split Inbox reorder/hide) with category-shifting AI work. The April MCP launch turned Superhuman Mail into a callable surface for Claude, ChatGPT, and other assistants, with 'uniquely Superhuman' actions (Smart Send, Read Statuses, Split Inbox triage) exposed as tools. Draft Sync with Gmail/Outlook bridges the agent ecosystem further: assistants can draft anywhere, you review and send in Superhuman.
The product is moving from 'fast email for power users' to 'AI-and-humans share the inbox.' Personalization, Write with Voice, and MCP form a clear stack — voice in, agent action, voice out — with the original power-user keyboard-shortcut audience preserved through continued Split Inbox refinement. Mobile gets weekly polish to keep that surface from rotting while the AI direction takes the headlines.
Next likely move is delegated-inbox MCP actions for executive assistants (act-as-on-behalf permissions) and recurring agent tasks tied to Personalization rules. A cross-app demo — Superhuman + Granola + a calendar tool, all via MCP — is the obvious narrative the May 21st virtual event has been set up to deliver.
