What is Stream?
Stream ships open-source Vision AI SDK for multi-modal app testing
Stream offers two core infrastructure APIs: real-time chat/messaging for in-app communication, and a new open-source Vision AI SDK for building and testing multi-modal AI applications. The Vision AI SDK supports live-edit-test workflows across modalities, targeting engineering teams iterating on AI features rather than end-user consumers.
What is Superhuman?
Superhuman goes all-in on AI connectivity and mobile parity in one sprint.
Superhuman has moved well past its speed-focused roots. The complete iOS/Android redesign delivers a mobile experience on par with the desktop app, while the multi-account MCP connector makes Superhuman the only email client that exposes multiple inboxes simultaneously to Claude and ChatGPT. The themes refresh is cosmetic, but the AI integrations are structural. Auto Drafts 2.0 eliminates the blank-page problem on every reply.
Stream vs Superhuman: editorial side-by-side
Stream

Stream ships open-source Vision AI SDK for multi-modal app testing
◆ Current state
Stream offers two core infrastructure APIs: real-time chat/messaging for in-app communication, and a new open-source Vision AI SDK for building and testing multi-modal AI applications. The Vision AI SDK supports live-edit-test workflows across modalities, targeting engineering teams iterating on AI features rather than end-user consumers.
◆ Where it's heading
Stream is extending beyond its established chat messaging infrastructure into AI-native developer tooling. The Vision AI SDK positions Stream as a building block for AI application developers, not just communication product teams. If this pattern continues, expect more AI-specific primitives shipped alongside the core messaging APIs.
◆ Prediction
The next move is likely deeper integration between the Vision AI SDK and Stream's existing messaging infrastructure, enabling AI apps that combine real-time communication with multi-modal inputs in a single SDK surface.
Superhuman
6.3COMMS
Superhuman goes all-in on AI connectivity and mobile parity in one sprint.
◆ Current state
Superhuman has moved well past its speed-focused roots. The complete iOS/Android redesign delivers a mobile experience on par with the desktop app, while the multi-account MCP connector makes Superhuman the only email client that exposes multiple inboxes simultaneously to Claude and ChatGPT. The themes refresh is cosmetic, but the AI integrations are structural. Auto Drafts 2.0 eliminates the blank-page problem on every reply.
◆ Where it's heading
Superhuman is positioning itself as the authoritative communications layer for AI agents — not just a fast email client. The MCP plugin and multi-account connectors are the rails; everything else (calendar on Android, mobile redesign, label sync) fills in the gaps needed to make that hub position credible. Expect each subsequent release to deepen AI orchestration over the inbox rather than adding standalone features.
◆ Prediction
AI-driven scheduling that bypasses manual share-availability flows is the next likely move — the calendar-on-Android feature and AI connectors are converging on a native booking experience that would let an AI agent schedule on a user's behalf without leaving Superhuman.
