What is Signal?
Closing the UX gap while pushing the crypto frontier.
Signal is running two parallel programs: a cryptographic agenda (post-quantum ratchet, defenses against Microsoft Recall) and a long-overdue UX parity push (secure backups, polls, pinned messages, group labels). The product has matured past pure privacy infrastructure and now ships features mainstream users have asked for for years. Each direction reinforces the brand: still the most paranoid messenger, but no longer the one that loses your chat history when your phone breaks.
What is Krisp?
Krisp is repositioning from noise cancellation to a contact-center voice-AI platform
Krisp's updates are now almost entirely 'Call Center AI': a new Voice Security line against AI voice fraud (deepfake detection, agent voice protection), expanding Voice Translation, Speech Analytics with Salesforce-fed scoring, Accent Conversion, and admin controls for translated calls. The consumer noise-cancellation roots have receded from the feed.

Closing the UX gap while pushing the crypto frontier.
◆ Current state
Signal is running two parallel programs: a cryptographic agenda (post-quantum ratchet, defenses against Microsoft Recall) and a long-overdue UX parity push (secure backups, polls, pinned messages, group labels). The product has matured past pure privacy infrastructure and now ships features mainstream users have asked for for years. Each direction reinforces the brand: still the most paranoid messenger, but no longer the one that loses your chat history when your phone breaks.
◆ Where it's heading
The cadence over the last 12 months shows a deliberate alternation between cryptographic milestones and feature catch-up. Backups, polls, pinned messages, and group labels are the kind of work Signal historically deferred; shipping them in quick succession signals a strategic decision to remove every easy reason a user might leave for WhatsApp or iMessage. Meanwhile SPQR positions the protocol for the next decade of cryptographic threat models, keeping the security story intact while the UX story finally catches up.
◆ Prediction
Secure backups will graduate from Android beta to iOS and Desktop within the next two releases. Expect another round of feature-parity work — message editing depth, richer media handling, or reactions — before the next protocol-level cryptographic move.

Krisp is repositioning from noise cancellation to a contact-center voice-AI platform
◆ Current state
Krisp's updates are now almost entirely 'Call Center AI': a new Voice Security line against AI voice fraud (deepfake detection, agent voice protection), expanding Voice Translation, Speech Analytics with Salesforce-fed scoring, Accent Conversion, and admin controls for translated calls. The consumer noise-cancellation roots have receded from the feed.
◆ Where it's heading
The product is moving up-market into contact centers, stacking real-time voice translation, analytics, agent assist, and now fraud defense into a CCaaS-adjacent suite. Voice Security is the newest and sharpest extension of the capability surface.
◆ Prediction
Expect Voice Security and Voice Translation to keep expanding, with deeper CRM integrations like the Salesforce link feeding analytics scoring.
