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 Krisp?
Krisp moves call transcripts and live captions to cloud transcription in KrispCX 2.84.4.
Krisp sells a Call Center AI suite to BPOs and contact centers: Accent Conversion, Voice Translation, QA scoring, deepfake and fraud detection. KrispCX 2.84.4 adds cloud transcription in beta for more accurate transcripts and Live Captions, plus in-call hints when the Krisp microphone is in use; the source note is truncated. October brought Conference mode for Voice Translation and a Fraud Detection beta.
Stream vs Krisp: 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.
Krisp
5.0COMMS
Krisp moves call transcripts and live captions to cloud transcription in KrispCX 2.84.4.
◆ Current state
Krisp sells a Call Center AI suite to BPOs and contact centers: Accent Conversion, Voice Translation, QA scoring, deepfake and fraud detection. KrispCX 2.84.4 adds cloud transcription in beta for more accurate transcripts and Live Captions, plus in-call hints when the Krisp microphone is in use; the source note is truncated. October brought Conference mode for Voice Translation and a Fraud Detection beta.
◆ Where it's heading
Releases arrive on a two-week cadence and keep stacking agent-assist features on the live call, from translation to fraud signals to captions. The September move to free-to-try has been followed by incremental depth rather than new product lines.
◆ Prediction
Expect more of the live-call layer to move to cloud processing, with QA scoring and translation likely reusing the new transcription. The truncated notes leave the scope of the cloud beta unclear.
