What is Superhuman?
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.
What is Rocket.Chat?
Rocket.Chat doubles down on enterprise governance — ABAC permissions and phishing-resistant MFA define the 8.x arc
Rocket.Chat is mid-stream on its 8.x release line, with active 8.3, 8.4, and 8.5 RC cycles in parallel and an LTS posture on 7.12/7.13 via security hotfixes. The bulk of substantive work clusters around two themes: attribute-based access control (ABAC) granularity and authentication hardening. The 8.4 RC stream layered file thumbnails, media-call REST control, livechat externalIds, and cold-storage read receipts onto that foundation.

Superhuman
6.3COMMS
Inbox becomes an MCP endpoint — agents now drive Superhuman alongside humans, in your voice.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.

Rocket.Chat doubles down on enterprise governance — ABAC permissions and phishing-resistant MFA define the 8.x arc
◆ Current state
Rocket.Chat is mid-stream on its 8.x release line, with active 8.3, 8.4, and 8.5 RC cycles in parallel and an LTS posture on 7.12/7.13 via security hotfixes. The bulk of substantive work clusters around two themes: attribute-based access control (ABAC) granularity and authentication hardening. The 8.4 RC stream layered file thumbnails, media-call REST control, livechat externalIds, and cold-storage read receipts onto that foundation.
◆ Where it's heading
The project is visibly preparing for a 9.0 boundary. The new skipTranspile flag for webhook integrations is explicitly marked deprecated and tied to Babel removal in 9.0, giving admins a per-integration validation path before the cliff. ABAC keeps getting decomposed — a Virtru PDP integration in 8.4, then four new permissions in 8.5 that split admin tab visibility. The 8.5 OAuth rewrite moves token handling fully server-side with PKCE, CSRF and state validation, and forces 2FA even on OAuth logins.
◆ Prediction
Expect 8.5.0 GA to ship with the phishing-resistant OAuth flow promoted as a headline security feature, followed by a 9.0 cut that removes Babel and tightens the apps-engine API boundary. The cadence of ABAC permission carve-outs suggests at least one more per minor release before the model stabilizes.
