What is Krisp?

Krisp adds deepfake detection and expands Voice Translation as its Call Center AI platform deepens enterprise compliance tools.

Krisp has shifted from a personal noise-cancellation app to a B2B Call Center AI platform, shipping weekly web updates and biweekly desktop releases. The current product spans real-time Voice Translation across 12+ languages including Cantonese and Valencian, Accent Conversion with per-regional models, and admin-layer tools including Conditional Call Recording, Live Call Audit enforcement, and a new Notification Center. A lower-cost evaluation tier appeared in August, suggesting friction at the top of the sales funnel.

What is Postmark?

Postmark ships Skills for AI coding agents and an async-first Python SDK — leaning into the agent-built-app era.

Postmark released two coordinated developer-platform moves. First, an open-source set of 'Postmark Skills' designed to teach AI coding agents — Claude Code, Cursor, GitHub Copilot, OpenAI Codex, Gemini CLI — accurate Postmark API context, covering send/batch/bulk, inbound, templates, webhooks, and message streams. Second, an official Python SDK built async-first, with split ServerClient and AccountClient surfaces and Python 3.10+ support. Around these, the team is highlighting bulk email send capabilities and routine maintenance (Axios 1.13.5 in the JS SDK).

Krisp adds deepfake detection and expands Voice Translation as its Call Center AI platform deepens enterprise compliance tools.

◆ Current state

Krisp has shifted from a personal noise-cancellation app to a B2B Call Center AI platform, shipping weekly web updates and biweekly desktop releases. The current product spans real-time Voice Translation across 12+ languages including Cantonese and Valencian, Accent Conversion with per-regional models, and admin-layer tools including Conditional Call Recording, Live Call Audit enforcement, and a new Notification Center. A lower-cost evaluation tier appeared in August, suggesting friction at the top of the sales funnel.

◆ Where it's heading

The update cadence and content point at enterprise expansion: each weekly batch adds granular admin controls, API access for audit data, and new BPO visibility tools. Voice Translation language coverage is widening consistently. Deepfake risk visibility—added in the most recent batch—signals Krisp moving into a trust-and-compliance layer for AI-assisted calls, not just audio quality.

◆ Prediction

The deepfake detection work is nascent; expect it to grow into a standalone compliance dashboard. Enterprise RFPs increasingly require call-authenticity guarantees, and Krisp's audio-layer position gives it a defensible angle on that problem that CRM or WFM vendors can't replicate.

Postmark logo2.5

Postmark ships Skills for AI coding agents and an async-first Python SDK — leaning into the agent-built-app era.

◆ Current state

Postmark released two coordinated developer-platform moves. First, an open-source set of 'Postmark Skills' designed to teach AI coding agents — Claude Code, Cursor, GitHub Copilot, OpenAI Codex, Gemini CLI — accurate Postmark API context, covering send/batch/bulk, inbound, templates, webhooks, and message streams. Second, an official Python SDK built async-first, with split ServerClient and AccountClient surfaces and Python 3.10+ support. Around these, the team is highlighting bulk email send capabilities and routine maintenance (Axios 1.13.5 in the JS SDK).

◆ Where it's heading

Postmark is positioning for a market where AI agents are the integrators, not just human developers. The Skills release is a direct response to the failure mode the team itself names — agents writing 'code that looks right but isn't' against transactional-email APIs. By shipping curated context as an open standard, Postmark stakes out the ground that whoever feeds correct knowledge into agent toolchains earns the integration calls. The async-first Python SDK fits the same thesis: agents and modern Python apps both want non-blocking calls by default.

◆ Prediction

Expect Postmark Skills to expand to inbound parsing and event-driven flows, and the open-standard framing to invite peer ESPs (Resend, Loops, Customer.io transactional) to publish their own Skills — at which point the question becomes whose Skills agents actually reach for. Watch for an MCP server next; it's the natural pairing with Skills for runtime tool calls.
