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 OpenPhone?
OpenPhone turns Sona into a deployable front-line AI agent with transfers and per-scenario instructions.
OpenPhone is hardening Sona, its AI phone agent, into something businesses can actually put in front of customers. Sona can now route calls to the right teammate when a human is needed, and admins can give it custom instructions per scenario (lead qualification, cancellations, booking) with templates to start from. Around it, the call flow builder keeps maturing: multiple routing setups with quick switching, in-place inbox switching during flow construction, and a Go-to Step primitive for cleaner branches.
Krisp vs OpenPhone: 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.
OpenPhone
0.0COMMS
OpenPhone turns Sona into a deployable front-line AI agent with transfers and per-scenario instructions.
◆ Current state
OpenPhone is hardening Sona, its AI phone agent, into something businesses can actually put in front of customers. Sona can now route calls to the right teammate when a human is needed, and admins can give it custom instructions per scenario (lead qualification, cancellations, booking) with templates to start from. Around it, the call flow builder keeps maturing: multiple routing setups with quick switching, in-place inbox switching during flow construction, and a Go-to Step primitive for cleaner branches.
◆ Where it's heading
The core bet is an AI-handles-first-contact, humans-handle-edge-cases pattern. Each Sona release is closing a deployment-blocker (instructions, transfers, free trial), while the call-flow tooling underneath is getting more flexible so AI and human routing can coexist in one config. Plan-tier expansion (call hold on Starter) suggests OpenPhone is also chasing volume in the lower segment.
◆ Prediction
Expect Sona to gain CRM-aware context (caller history, deal state) and outbound use cases — proactive callbacks, scheduled follow-ups. Pricing for Sona usage is likely to evolve from a flat add-on toward usage- or outcome-based once volume appears.
