What is Gromox?
Gromox is filling in Exchange Web Services fast enough to matter for non-Outlook clients.
Gromox ships a minor roughly every four to eight weeks and has moved from 3.0 to 3.9 in this window. The centre of gravity is EWS: 3.6 landed roughly two dozen operations at once — task CRUD, delegate management, calendar occurrences with timezones, full meeting invitation and cancellation lifecycle, read receipts — and every release since has extended or corrected it. Alongside that, 3.8 introduced a per-store split-process model for the Information Store and partial IMAP4rev2 support, and 3.9 made auto-accepted room bookings send confirmations and handle cancellations.
What is Krisp?
Krisp has stopped being a noise-cancellation utility and become a contact-center voice platform.
Every entry in the last two months is filed under Call Center AI. The product now spans Voice Translation, Accent Conversion, Voice Security with deepfake detection and agent voice verification, Speech Analytics with screen recording, and an Enterprise Analytics Portal for sharing results with clients. Releases alternate between web-side batches roughly weekly and desktop app builds, and admin controls appear in nearly every one.
Gromox vs Krisp: editorial side-by-side
Gromox
2.5COMMS
Gromox is filling in Exchange Web Services fast enough to matter for non-Outlook clients.
◆ Current state
Gromox ships a minor roughly every four to eight weeks and has moved from 3.0 to 3.9 in this window. The centre of gravity is EWS: 3.6 landed roughly two dozen operations at once — task CRUD, delegate management, calendar occurrences with timezones, full meeting invitation and cancellation lifecycle, read receipts — and every release since has extended or corrected it. Alongside that, 3.8 introduced a per-store split-process model for the Information Store and partial IMAP4rev2 support, and 3.9 made auto-accepted room bookings send confirmations and handle cancellations.
◆ Where it's heading
The project is working outward from MAPI compatibility toward the protocols that non-Outlook clients actually speak. EWS is the clearest case, but the same pattern shows in IMAP (custom keywords, IMAP4rev2 commands, SENT* keywords fixed to test the Date header as the spec requires) and in AutoDiscover fixes that unblocked Thunderbird. A second, quieter thread is offloading format conversion to external tools — Pandoc for HTML/RTF, Chawan for HTML-to-text — rather than maintaining converters in-tree. Meeting and calendar handling generates the most fix traffic, which is what you would expect from the hardest part of an Exchange-compatible server.
◆ Prediction
Expect EWS coverage to keep expanding toward whatever operations remain unimplemented, since that has been the consistent destination of feature work for five releases. The split-process Information Store introduced in 3.8 is the other thread to watch — a config bitmask suggests further isolation work is planned rather than finished.
Krisp
6.3COMMS
Krisp has stopped being a noise-cancellation utility and become a contact-center voice platform.
◆ Current state
Every entry in the last two months is filed under Call Center AI. The product now spans Voice Translation, Accent Conversion, Voice Security with deepfake detection and agent voice verification, Speech Analytics with screen recording, and an Enterprise Analytics Portal for sharing results with clients. Releases alternate between web-side batches roughly weekly and desktop app builds, and admin controls appear in nearly every one.
◆ Where it's heading
The direction is real-time voice manipulation sold to contact centers, not consumers. Accent Conversion now runs on both sides of a call, translation gained speed control and a spelling mode for names and numbers, and the language list keeps growing. Voice Security is the defensive counterpart — the same synthesis capability that powers accent conversion is what makes deepfake detection necessary, and Krisp is selling both sides. The steady stream of admin controls, audit logs, and automated data cleanup shows an enterprise procurement checklist being worked through.
◆ Prediction
Expect the language and accent model coverage to keep widening and Voice Security to move from paid trial toward general availability. The portal API gaining audit logs suggests more of the admin surface will become programmatic.
