What is Knock?
Knock is pushing its agent into more surfaces while making notification config a no-engineering job.
Knock, a notifications-infrastructure platform, is building two parallel tracks: an agent that can create and manage messaging resources from inside tools like Slack, and a steady stream of dashboard-driven features that move configuration work off engineers. Recent releases span a hosted preference center, dynamic audiences, new data sources, and template tooling. The product is widening from a developer API toward a self-serve control surface.
What is ElevenLabs?
ElevenLabs widens from TTS into a full voice-agent and music platform
ElevenLabs is shipping on two fronts: new foundational capabilities, a Music v2 model with chunk-based composition and Speech Engine, which adds real-time voice to a developer's own agent or LLM, and a relentless cadence of ElevenAgents API work (Exotel telephony, workflow-aware transfers, new LLM options, SIP logs, knowledge-base editing) plus deprecations of v1 TTS/STT models and weekly SDK regenerations.

Knock
6.3INFRA · APIS
Knock is pushing its agent into more surfaces while making notification config a no-engineering job.
◆ Current state
Knock, a notifications-infrastructure platform, is building two parallel tracks: an agent that can create and manage messaging resources from inside tools like Slack, and a steady stream of dashboard-driven features that move configuration work off engineers. Recent releases span a hosted preference center, dynamic audiences, new data sources, and template tooling. The product is widening from a developer API toward a self-serve control surface.
◆ Where it's heading
The direction is toward less engineering involvement per change — agents, dashboard-built audiences, and hosted end-user UI all shorten the code path. Integrations like the Shopify data source extend Knock's triggers into commerce events, broadening what notifications can be driven by. The agent and the dashboard keep absorbing tasks that previously required custom code.
◆ Prediction
The next moves likely deepen the agent (more surfaces or skills) and add further data sources, continuing the shift toward dashboard- and agent-driven configuration over hand-written integration code.

ElevenLabs widens from TTS into a full voice-agent and music platform
◆ Current state
ElevenLabs is shipping on two fronts: new foundational capabilities, a Music v2 model with chunk-based composition and Speech Engine, which adds real-time voice to a developer's own agent or LLM, and a relentless cadence of ElevenAgents API work (Exotel telephony, workflow-aware transfers, new LLM options, SIP logs, knowledge-base editing) plus deprecations of v1 TTS/STT models and weekly SDK regenerations.
◆ Where it's heading
The company is consolidating into a voice-AI platform: owning the model layer (music, TTS, STT, turn detection) while making ElevenAgents and Speech Engine the programmable runtime others build conversational voice on. Aggressive deprecation signals confidence in pushing customers to current models.
◆ Prediction
Expect Speech Engine and Music v2 to mature with more controls, continued ElevenAgents telephony and workflow depth, and further old-model sunsets.
