LiveKit is a platform designed to facilitate real-time AI and multimedia communications. It enables the instantaneous transmission of audio and video between language models (LLMs) and users, creating real-time multimodal experiences. LiveKit provides tools for developing voice AI, robotics, and livestreaming applications, with ultra-low latency and high resilience. It supports integration with telephony networks, simulating human conversation with advanced features like interruption handling and turn-taking cue detection. The platform is geared towards developers, offering SDK support across all major platforms, allowing applications to be deployed and scaled efficiently. LiveKit is open-source under Apache 2. 0 and offers robust security measures, including end-to-end encryption and compliance with GDPR, SOC2 Type 2, CCPA, and HIPAA.
