What is Delta Chat?
Delta Chat is quietly replacing its email identity with relays
Delta Chat desktop v2.65.0 adds pinned messages, message multiselect actions and a System default language option, and hides individual reactions from channel owners. v2.62.0 changed more of the foundation: relays can be removed, the default relay setting is gone, onboarding adds several relays, and email addresses are no longer shown for profiles. Contacts are also no longer shown as verified.
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.

Delta Chat is quietly replacing its email identity with relays
◆ Current state
Delta Chat desktop v2.65.0 adds pinned messages, message multiselect actions and a System default language option, and hides individual reactions from channel owners. v2.62.0 changed more of the foundation: relays can be removed, the default relay setting is gone, onboarding adds several relays, and email addresses are no longer shown for profiles. Contacts are also no longer shown as verified.
◆ Where it's heading
The project is removing email from what users see and from how they think about identity, with relays taking its place as multi-path infrastructure. Fetching from every relay and sending through the fastest one treats a relay as replaceable, which matters for a federated messenger. Around that, the client keeps closing feature gaps with mainstream messengers through pinning, channel reactions and better group notification handling.
◆ Prediction
Expect further relay management work, as the core notes show this is where the structural change is. Channels are the next most active surface, with reaction privacy already changing there.
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.
