What is Superhuman?

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.

What is SimpleX Chat?

SimpleX builds out channels in the v7.0 beta, layering broadcast roles onto its no-identifiers messenger

SimpleX Chat is mid-way through its v7.0 beta cycle, and the throughline is channels: web previews to read posts before joining, owner-managed relays, promotable subscriber-to-contributor roles, and supporter badges. Interleaved with the feature betas are armv7a build tags that are merge-only and carry no release content.

Superhuman vs SimpleX Chat: editorial side-by-side

S5.0

Superhuman pushes calendar onto mobile and opens the inbox to AI agents via MCP.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.

S6.3

SimpleX builds out channels in the v7.0 beta, layering broadcast roles onto its no-identifiers messenger

◆ Current state

SimpleX Chat is mid-way through its v7.0 beta cycle, and the throughline is channels: web previews to read posts before joining, owner-managed relays, promotable subscriber-to-contributor roles, and supporter badges. Interleaved with the feature betas are armv7a build tags that are merge-only and carry no release content.

◆ Where it's heading

The privacy-first, no-user-identifiers messenger is adding a broadcast/community layer on top of its 1:1 and group foundations. v7.0 reads as SimpleX's push toward public channels as a first-class surface, with the role system (owners, contributors, subscribers, supporters) and relay management being the scaffolding for larger, semi-public communities while keeping the metadata-minimal model.

◆ Prediction

Expect v7.0 to stabilize out of beta with channels fully fleshed out, and the supporter-badge work to hint at a creator/monetization angle for channel owners.
