What is Krisp?
Krisp Call Center AI ships weekly: Voice Translation expands to Cantonese, Accent Conversion adds Indian accent.
Krisp is executing a high-cadence weekly release cycle exclusively focused on its Call Center AI platform. Each release adds Voice Translation language support (now including Cantonese and Valencian, with accuracy improvements for Spanish and Japanese), new Accent Conversion models (Indian accent added this week), and supervisor/admin tooling (live call audit enforcement, conditional call recording, enterprise analytics for BPOs). The product has shifted almost entirely from its consumer noise-cancellation origins toward a B2B call center platform.
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 Call Center AI ships weekly: Voice Translation expands to Cantonese, Accent Conversion adds Indian accent.
◆ Current state
Krisp is executing a high-cadence weekly release cycle exclusively focused on its Call Center AI platform. Each release adds Voice Translation language support (now including Cantonese and Valencian, with accuracy improvements for Spanish and Japanese), new Accent Conversion models (Indian accent added this week), and supervisor/admin tooling (live call audit enforcement, conditional call recording, enterprise analytics for BPOs). The product has shifted almost entirely from its consumer noise-cancellation origins toward a B2B call center platform.
◆ Where it's heading
Krisp is expanding along two parallel tracks: language coverage (Voice Translation and Accent Conversion reaching more global locales and accent profiles) and supervisor infrastructure (QA scoring, live audit enforcement, compliance reporting). The weekly cadence across web and desktop releases indicates organized sprint delivery targeting enterprise call center buyers. As language and accent support broadens, Krisp's addressable market expands to non-US call centers that have historically been underserved by English-centric AI tools.
◆ Prediction
Accent Conversion will extend to more regional accent profiles beyond Indian, and Voice Translation will continue adding languages. Admin compliance features — like Conditional Call Recording and Live Audit enforcement — will deepen as enterprise procurement cycles require documentation of call-center AI governance.
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.
