What is Tuta?
Tuta's One-Click Migration can now pull mail through Google and Microsoft APIs, not just IMAP.
Tuta is an encrypted email, calendar and drive suite that ships one numbered build across web, desktop, Android and iOS. The 368.261109 build adds the option to open attachments while composing and lets One-Click Migration import from Gmail and Microsoft accounts through their APIs as well as IMAP. The rest of the batch is bug fixes: list selection flashing, spam rules not updating, alias deactivation for shared mailboxes and connection errors during migration.
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.

Tuta
5.0COMMS
Tuta's One-Click Migration can now pull mail through Google and Microsoft APIs, not just IMAP.
◆ Current state
Tuta is an encrypted email, calendar and drive suite that ships one numbered build across web, desktop, Android and iOS. The 368.261109 build adds the option to open attachments while composing and lets One-Click Migration import from Gmail and Microsoft accounts through their APIs as well as IMAP. The rest of the batch is bug fixes: list selection flashing, spam rules not updating, alias deactivation for shared mailboxes and connection errors during migration.
◆ Where it's heading
The visible product work is aimed at switching: the migration tool keeps gaining source options and its error handling is getting attention, including the Proton Mail Bridge path. Releases fan out to every platform within hours, so most entries are the same fix list repeated per client.
◆ Prediction
Expect more migration fixes and sources in the next builds, plus follow-up patches like the November 10 mailto fix on the web app.
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.
