What is Krisp?
Krisp has stopped being a noise-cancellation utility and become a contact-center voice platform.
Every entry in the last two months is filed under Call Center AI. The product now spans Voice Translation, Accent Conversion, Voice Security with deepfake detection and agent voice verification, Speech Analytics with screen recording, and an Enterprise Analytics Portal for sharing results with clients. Releases alternate between web-side batches roughly weekly and desktop app builds, and admin controls appear in nearly every one.
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
6.3COMMS
Krisp has stopped being a noise-cancellation utility and become a contact-center voice platform.
◆ Current state
Every entry in the last two months is filed under Call Center AI. The product now spans Voice Translation, Accent Conversion, Voice Security with deepfake detection and agent voice verification, Speech Analytics with screen recording, and an Enterprise Analytics Portal for sharing results with clients. Releases alternate between web-side batches roughly weekly and desktop app builds, and admin controls appear in nearly every one.
◆ Where it's heading
The direction is real-time voice manipulation sold to contact centers, not consumers. Accent Conversion now runs on both sides of a call, translation gained speed control and a spelling mode for names and numbers, and the language list keeps growing. Voice Security is the defensive counterpart — the same synthesis capability that powers accent conversion is what makes deepfake detection necessary, and Krisp is selling both sides. The steady stream of admin controls, audit logs, and automated data cleanup shows an enterprise procurement checklist being worked through.
◆ Prediction
Expect the language and accent model coverage to keep widening and Voice Security to move from paid trial toward general availability. The portal API gaining audit logs suggests more of the admin surface will become programmatic.
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.
