Superhuman vs SimpleX Chat
Side-by-side trajectory, velocity, and editorial themes.
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.
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.
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.
SimpleX's v7.0 beta grows a private messenger into a public-channel network
SimpleX is deep in the v7.0 beta cycle, and the through-line is channels. Successive betas have added subscriber and contributor roles, CLI channel connections, obfuscated-link moderation, and now registered SimpleX names for channels and businesses. The metadata-free privacy model stays intact, but the product is growing a public broadcast surface it didn't previously have.
Each beta hardens the channels stack — roles, moderation, web previews, relay management — while chipping away at connection stability and delivery in large groups. The move to registered SimpleX names for channels and business accounts points toward discoverable, addressable identities, a notable shift for a network built on unaddressed contact. The remaining betas look aimed at stabilizing delivery and finalizing the naming and business layer before a 7.0 stable.
The next beta most likely locks down the SimpleX names registration flow, currently gated behind test infrastructure, and continues group-delivery stability work ahead of a 7.0 stable release.
