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.
Wati's feed is all WhatsApp marketing content, not product releases
The tracked feed for Wati is a content-marketing blog, not a product changelog: every recent entry is an SEO-oriented article about WhatsApp Business API, Meta Business Agent, drip campaigns, and voice agents rather than a shipped change to the Wati platform. What signal does exist points to Wati positioning itself around Meta's new Business Agent (repeatedly arguing it complements rather than replaces the WhatsApp Business API) and around WhatsApp native voice/calling. No actual version, capability, or pricing change is observable in these entries.

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.

No actual version, capability, or pricing change is observable in these entries.
Editorially, Wati is leaning hard into two narratives: defending the WhatsApp Business API's value against Meta's free Business Agent, and pushing WhatsApp-native voice/AI-agent calling. These are marketing themes, not release evidence, so trajectory on the product itself is unclear from this feed. The recurring Meta-Business-Agent framing suggests Wati sees Meta's move as the competitive story it most needs to shape for customers.
The feed is a blog, not a changelog, so a grounded product-move prediction isn't supported by these entries; expect continued content cadence around Meta Business Agent and WhatsApp voice rather than observable product changes here.
