What is Krisp?

Krisp adds deepfake detection and expands Voice Translation as its Call Center AI platform deepens enterprise compliance tools.

Krisp has shifted from a personal noise-cancellation app to a B2B Call Center AI platform, shipping weekly web updates and biweekly desktop releases. The current product spans real-time Voice Translation across 12+ languages including Cantonese and Valencian, Accent Conversion with per-regional models, and admin-layer tools including Conditional Call Recording, Live Call Audit enforcement, and a new Notification Center. A lower-cost evaluation tier appeared in August, suggesting friction at the top of the sales funnel.

What is SMTP2GO?

Deliverability blogging with one real API release buried in the run

Most of the feed is deliverability education and comparison content: a scan-to-email setup and troubleshooting guide, a third-party ranking from EmailToolTester, a tested top five of transactional email services, a spam-avoidance playbook, and a definitional piece on transactional email. The exception is June's API release, which added scheduled sending, throughput improvements and more efficient large-batch sending.

Krisp vs SMTP2GO: editorial side-by-side

Krisp adds deepfake detection and expands Voice Translation as its Call Center AI platform deepens enterprise compliance tools.

◆ Current state

Krisp has shifted from a personal noise-cancellation app to a B2B Call Center AI platform, shipping weekly web updates and biweekly desktop releases. The current product spans real-time Voice Translation across 12+ languages including Cantonese and Valencian, Accent Conversion with per-regional models, and admin-layer tools including Conditional Call Recording, Live Call Audit enforcement, and a new Notification Center. A lower-cost evaluation tier appeared in August, suggesting friction at the top of the sales funnel.

◆ Where it's heading

The update cadence and content point at enterprise expansion: each weekly batch adds granular admin controls, API access for audit data, and new BPO visibility tools. Voice Translation language coverage is widening consistently. Deepfake risk visibility—added in the most recent batch—signals Krisp moving into a trust-and-compliance layer for AI-assisted calls, not just audio quality.

◆ Prediction

The deepfake detection work is nascent; expect it to grow into a standalone compliance dashboard. Enterprise RFPs increasingly require call-authenticity guarantees, and Krisp's audio-layer position gives it a defensible angle on that problem that CRM or WFM vendors can't replicate.

Deliverability blogging with one real API release buried in the run

◆ Current state

Most of the feed is deliverability education and comparison content: a scan-to-email setup and troubleshooting guide, a third-party ranking from EmailToolTester, a tested top five of transactional email services, a spam-avoidance playbook, and a definitional piece on transactional email. The exception is June's API release, which added scheduled sending, throughput improvements and more efficient large-batch sending.

◆ Where it's heading

SMTP2GO's product signal arrives roughly once a quarter and always concerns the sending path — scheduling, throughput, batch efficiency — aimed at high-volume senders rather than at the dashboard. Everything between those releases is search-oriented content built around deliverability anxiety, plus independent ranking results used as proof.

◆ Prediction

On the pattern of the June release, further API work on sending at scale is the most likely next product entry; the intervening posts will stay educational.
