Overview
AssemblyAI
AssemblyAI gives you the tools to build powerful AI features into your products using simple APIs. You can transcribe audio and video files with high accuracy, identify different speakers in a recording, and extract actionable insights like sentiment, summaries, and key topics automatically. It handles the complex heavy lifting of machine learning so you can focus on building your core application.
Whether you are building a meeting assistant, a content moderation tool, or a media analysis platform, you can scale your processing from a few files to millions of hours of audio. The platform supports both asynchronous file processing and real-time streaming, making it a flexible choice for developers and enterprises across industries like telecommunications, healthcare, and media.
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.
