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.
What is NanoMQ?
NanoMQ follows its hardening run by moving onto Zephyr microcontrollers.
NanoMQ 0.25.7, published on 21 October and described as a beta, runs on the Zephyr RTOS after platform-layer work on memory allocation for microkernel environments. It also pushes the multi-tenant mountpoint logic down into the transport layer, gives each bridge its own cache with REST control, lets operators kick clients by ID over the API, and supports PKCS#11 hardware keys with certificate-to-username mapping. 0.25.6 in August had been a protocol-conformance and auth-race fix release.
Krisp vs NanoMQ: editorial side-by-side
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.
NanoMQ
2.5COMMS
NanoMQ follows its hardening run by moving onto Zephyr microcontrollers.
◆ Current state
NanoMQ 0.25.7, published on 21 October and described as a beta, runs on the Zephyr RTOS after platform-layer work on memory allocation for microkernel environments. It also pushes the multi-tenant mountpoint logic down into the transport layer, gives each bridge its own cache with REST control, lets operators kick clients by ID over the API, and supports PKCS#11 hardware keys with certificate-to-username mapping. 0.25.6 in August had been a protocol-conformance and auth-race fix release.
◆ Where it's heading
0.25.5 dropped MIPS and ARMel binaries to concentrate on correctness, and 0.25.6 spent that effort on MQTT conformance. 0.25.7 points the broker at smaller and more locked-down hardware instead: an RTOS target, hardware security modules and per-device certificate identity. That is a move toward embedded, fleet-managed deployments rather than gateway servers.
◆ Prediction
Expect follow-up 0.25.x releases fixing Zephyr-specific issues, since 0.25.7 is labelled a first beta. The SipHash client ID question raised in 0.25.2 still has no resolution in these entries.
