What is Krisp?
Salesforce CRM data now sharpens Krisp's Speech Analytics — the contact-center AI buildout continues weekly.
Krisp ships weekly batches against a single product surface: Call Center AI. This past month brought a Salesforce connector that feeds CRM context into Speech Analytics scoring, expanded Voice Translation (new languages, refreshed voices, Quick Phrases management, automatic language selection, Krisp Bridge on Edge), restored VT usage reporting, and a 2.77.5 release touching Voice Translation, Agent Assist, and Speech Analytics together. Admin tooling and trial-onboarding got their own batch.
What is Delta Chat?
Email-based messenger steadily adding calls, mini-apps, and multi-transport
Delta Chat's desktop app is on a fast, feature-dense release cadence. Recent releases built out real-time calls (ringing tones, device selection, a 'who can call me' setting, TURN relays), WebXDC mini-apps (clickable links, faster and safer loading), channels with descriptions and view counts, and multi-transport support letting one account span several mail servers. The latest (v2.49.1) is a macOS crash hotfix.

Krisp
5.0COMMS
Salesforce CRM data now sharpens Krisp's Speech Analytics — the contact-center AI buildout continues weekly.
◆ Current state
Krisp ships weekly batches against a single product surface: Call Center AI. This past month brought a Salesforce connector that feeds CRM context into Speech Analytics scoring, expanded Voice Translation (new languages, refreshed voices, Quick Phrases management, automatic language selection, Krisp Bridge on Edge), restored VT usage reporting, and a 2.77.5 release touching Voice Translation, Agent Assist, and Speech Analytics together. Admin tooling and trial-onboarding got their own batch.
◆ Where it's heading
The product's positioning has fully consolidated around contact-center AI — the consumer noise-cancellation roots are barely visible in the current changelog. Every recent batch reinforces three vectors: multilingual reach (Voice Translation, Accent Conversion), enterprise data context (Salesforce integration, admin controls), and call-quality surfaces (Speech Analytics, Agent Assist). The cadence is high — every week ships visible product changes.
◆ Prediction
Expect more CRM integrations beyond Salesforce (Zendesk and HubSpot are the obvious next targets) and continued Voice Translation language expansion. Speech Analytics will likely deepen now that it has CRM context to compare against.
Delta Chat

Email-based messenger steadily adding calls, mini-apps, and multi-transport
◆ Current state
Delta Chat's desktop app is on a fast, feature-dense release cadence. Recent releases built out real-time calls (ringing tones, device selection, a 'who can call me' setting, TURN relays), WebXDC mini-apps (clickable links, faster and safer loading), channels with descriptions and view counts, and multi-transport support letting one account span several mail servers. The latest (v2.49.1) is a macOS crash hotfix.
◆ Where it's heading
The product is pushing well beyond classic email chat toward a full messenger: calling, mini-apps, and broadcast channels are all maturing in parallel, while the v2.33 multi-transport work (a breaking backup-format change) re-architected accounts to span multiple transports. The throughline is closing the feature gap with mainstream messengers while keeping the email/chatmail foundation.
◆ Prediction
Expect continued buildout of calls and WebXDC mini-apps, plus polish on the newer channels and multi-transport features. Frequent point releases with occasional hotfixes will likely persist.
