What is Slack?
Slack's developer platform goes agent-first, adding context and messaging surfaces for agentic apps.
Slack's developer platform is in an agent-first phase. The changelog is dominated by primitives for building agentic apps — most notably agent context (apps now learn what a user is viewing) and a new agent messaging experience — layered on top of steady Block Kit, SDK, and CLI maintenance.
What is Krisp?
Krisp expands from noise cancellation into a full call-center AI stack — now with voice-fraud defense
Krisp has grown well past its noise-cancellation roots into a Call Center AI suite spanning Accent Conversion, Voice Translation (now v3), Speech Analytics, and a new Voice Security line. The recent cadence is a steady drip of biweekly web updates and monthly roundups, with real feature depth: real-time translated-call oversight, admin and audit controls, and CRM data feeding analytics scoring.

Slack's developer platform goes agent-first, adding context and messaging surfaces for agentic apps.
◆ Current state
Slack's developer platform is in an agent-first phase. The changelog is dominated by primitives for building agentic apps — most notably agent context (apps now learn what a user is viewing) and a new agent messaging experience — layered on top of steady Block Kit, SDK, and CLI maintenance.
◆ Where it's heading
The clear direction is turning Slack into a runtime for AI agents, not just a chat surface. Agent context gives apps situational awareness of the open channel, DM, thread, canvas, or list; the agent messaging experience gives them a purpose-built interaction model. Around this, Block Kit gains new primitives (the container block) and the SDK/CLI receive routine reliability updates, keeping the platform's foundations current while the agent surface expands.
◆ Prediction
Expect Slack to keep extending the agent platform — richer context payloads, more agent-native UI primitives in Block Kit, and SDK support that makes context-aware agents easier to build.

Krisp expands from noise cancellation into a full call-center AI stack — now with voice-fraud defense
◆ Current state
Krisp has grown well past its noise-cancellation roots into a Call Center AI suite spanning Accent Conversion, Voice Translation (now v3), Speech Analytics, and a new Voice Security line. The recent cadence is a steady drip of biweekly web updates and monthly roundups, with real feature depth: real-time translated-call oversight, admin and audit controls, and CRM data feeding analytics scoring.
◆ Where it's heading
The arc runs from cleaning up audio toward reshaping and securing it in real time for contact centers — translating and accent-converting live calls, then defending those calls against AI voice fraud. Voice Security, with deepfake detection and agent-voice verification, is the notable direction change: Krisp is now selling trust in the voice channel, not just clarity. Admin controls, audit trails, and Salesforce integration show the suite hardening for enterprise contact-center buyers.
◆ Prediction
Expect Voice Security to broaden beyond deepfake detection into more fraud vectors, and translation plus analytics to deepen their CRM ties as Krisp pushes the full suite into enterprise contact centers.
