Overview
Amazon Alexa
Amazon Alexa is a voice-driven AI platform that helps you build interactive voice experiences and manage smart environments. You can use the Alexa Skills Kit to create custom capabilities that let users interact with your services through simple voice commands. It handles the complex natural language processing and speech recognition so you can focus on the core logic of your application.
The platform also enables you to connect and control thousands of smart home devices from a single interface. Whether you are a developer building the next big voice app or a business looking to automate your office environment, Alexa provides the tools to make technology more accessible through conversation. You can manage everything from simple reminders to complex multi-device routines with ease.
Krisp
Krisp is an AI productivity layer that sits between your microphone/speaker and your communication apps to eliminate distracting background noise. You can use it to remove barking dogs, crying babies, or keyboard clicks from your calls in real-time. It works bi-directionally, meaning you can cancel noise coming from your own environment and also mute the noise coming from other participants on the call.
Beyond noise cancellation, you can automatically record and transcribe your meetings with AI-generated summaries and action items. It integrates with over 800 apps, including Zoom, Microsoft Teams, and Google Meet, without requiring any special hardware. Whether you are a remote freelancer or part of a large enterprise call center, you can maintain professional audio quality regardless of your physical surroundings.
