What is Dendrite?

A forked, relicensed Dendrite spent its first year catching up on Matrix protocol and security debt

The window opens with the first release after forking from matrix-org/dendrite under AGPLv3, which fixed long-standing state-reset bugs and added I2P and Onion listening. What follows is a security release closing a server-side request forgery vulnerability, then a release adding room version 12 support and two MSC implementations, and finally two quick patches for unresponsiveness, v12 room joins and malformed PDUs blocking whole transactions.

What is Superhuman?

Superhuman rebuilt its mobile apps and wired every inbox into AI assistants — the email client is becoming a suite.

Superhuman has evolved from a keyboard-shortcut email client into an AI-native communication platform covering email, calendar, and AI drafting agents — all gated on Business/Enterprise tiers. The mobile apps, long a weak point relative to desktop, received their first major overhaul in years with a redesigned navigation model and native iOS/Android aesthetics. MCP support with multi-account access is live, letting AI assistants like Claude and ChatGPT operate across all connected inboxes simultaneously. Calendar coverage now spans desktop, Android, and iOS with room booking and multi-day views.

Dendrite vs Superhuman: editorial side-by-side

D0.0

A forked, relicensed Dendrite spent its first year catching up on Matrix protocol and security debt

◆ Current state

The window opens with the first release after forking from matrix-org/dendrite under AGPLv3, which fixed long-standing state-reset bugs and added I2P and Onion listening. What follows is a security release closing a server-side request forgery vulnerability, then a release adding room version 12 support and two MSC implementations, and finally two quick patches for unresponsiveness, v12 room joins and malformed PDUs blocking whole transactions.

◆ Where it's heading

This is a fork proving it can carry a homeserver. The order is telling: license and state correctness first, then a CVE, then protocol currency with room version 12, then the operational bugs that surface once people actually run it. Several fixes carry outside contributor credits, which is the fork's clearest sign of life.

◆ Prediction

Expect continued protocol catch-up on newer MSCs and room versions plus operational fixes, since federation compatibility is the constraint that sets this project's agenda.

S6.3

Superhuman rebuilt its mobile apps and wired every inbox into AI assistants — the email client is becoming a suite.

◆ Current state

Superhuman has evolved from a keyboard-shortcut email client into an AI-native communication platform covering email, calendar, and AI drafting agents — all gated on Business/Enterprise tiers. The mobile apps, long a weak point relative to desktop, received their first major overhaul in years with a redesigned navigation model and native iOS/Android aesthetics. MCP support with multi-account access is live, letting AI assistants like Claude and ChatGPT operate across all connected inboxes simultaneously. Calendar coverage now spans desktop, Android, and iOS with room booking and multi-day views.

◆ Where it's heading

Superhuman is building toward a unified communication suite — the rebranded 'Superhuman Mail' name explicitly anticipates Mail, Docs, and Go as sibling products. The heavy investment in calendar (rooms, Android, multi-day iOS views) signals calendar parity with email as a near-term priority. AI drafting is moving toward full automation: Auto Drafts 2.0 already completes 60% of replies without editing, and the team has announced a voice mode and a rewritten email engine as the next milestones.

◆ Prediction

Voice mode and a rewritten email engine are both on the stated roadmap. The most likely next shipping moment is deeper tool integrations for Auto Drafts — Slack and meeting-notes context were specifically teased — which would close the gap between drafting and the rest of a user's work context.
