What is Krisp?
Krisp's September roundup adds translation accuracy reports and voice flags.
Krisp is now a Call Center AI platform for BPOs and enterprise contact centers, bundling Accent Conversion, Voice Translation, QA scoring, deepfake risk detection and conditional recording. Call Center AI became free to try in September, and release 2.82.6 added a Fraud Detection beta for agents in live calls. The September roundup, published October 19, adds clearer translation accuracy reporting and flags for potential voice issues, though the entry is truncated.
What is Slack?
Slack raises the Marketplace bar back to ten installs while the agent platform consolidates.
Slack's developer platform runs two tracks. The agent build-out has produced a spark roughly every two weeks since June — MCP client, a skills plugin targeting Claude Code and Cursor, and Slack Code — and now has a consolidation date attached: assistant_view is deprecated in February 2027, replaced by an Agent Sessions API. The second track is platform administration and tooling, and this window belongs to it: Marketplace submissions again require at least ten installed active workspaces, held throughout the review, after a period at a lower temporary threshold. The CLI has shipped three times since late July.

Krisp
6.3COMMS
Krisp's September roundup adds translation accuracy reports and voice flags.
◆ Current state
Krisp is now a Call Center AI platform for BPOs and enterprise contact centers, bundling Accent Conversion, Voice Translation, QA scoring, deepfake risk detection and conditional recording. Call Center AI became free to try in September, and release 2.82.6 added a Fraud Detection beta for agents in live calls. The September roundup, published October 19, adds clearer translation accuracy reporting and flags for potential voice issues, though the entry is truncated.
◆ Where it's heading
The security layer is expanding fastest: deepfake risk visibility in early September, fraud detection in-call in October. Reporting is catching up behind it, with accuracy reporting for translation now joining QA scoring. The product is moving from making agents sound better toward protecting and auditing the call itself.
◆ Prediction
Expect Fraud Detection to leave beta and feed the same alert integrations and QA dashboards as deepfake risk. The September roundup is cut off mid-sentence, so what its voice flags cover is unclear.
Slack
6.3COMMSCOLLAB
Slack raises the Marketplace bar back to ten installs while the agent platform consolidates.
◆ Current state
Slack's developer platform runs two tracks. The agent build-out has produced a spark roughly every two weeks since June — MCP client, a skills plugin targeting Claude Code and Cursor, and Slack Code — and now has a consolidation date attached: assistant_view is deprecated in February 2027, replaced by an Agent Sessions API. The second track is platform administration and tooling, and this window belongs to it: Marketplace submissions again require at least ten installed active workspaces, held throughout the review, after a period at a lower temporary threshold. The CLI has shipped three times since late July.
◆ Where it's heading
The install requirement moving back up is a distribution decision arriving in the middle of a platform push, and the two point the same way. Slack is making it easier to build agents and harder to list one, which favours developers who already have distribution — existing workspace tools and vendors — over a new app hoping the Marketplace supplies its first users. Combined with the assistant deprecation and the Agent Sessions API, the platform is narrowing on one agent surface and one class of builder rather than widening the funnel.
◆ Prediction
The threshold is described as a return from a temporary lower bar rather than a new policy, so the open question is what replaces the Marketplace as the discovery path for an app that cannot reach ten workspaces on its own. These entries do not answer it.
