Napster
Napster is a platform of AI agents for music creation, personal sessions, business websites, and developer use, available on web, Windows, macOS, iOS, Android, and through an API. Napster App includes nine music agents for shaping lyrics, tempo, and feel, creating cover art, and sharing songs. It also offers conversational AI audiobooks, meditation and wellness sessions, and generated music, stories, and soundscapes. Napster for Mac adds video conversations, screen sharing, and agents that create editable websites, plans, designs, and code. Businesses can use Napster Agent, which builds product knowledge by crawling a business website and can be deployed with one line of code to guide visitors and help convert them. It integrates with Shopify and WooCommerce. The API supports video, audio, and telephony agents through REST APIs, a Web SDK, WebRTC, and WebSockets; using it requires access to the website's code. Napster says its model-agnostic platform is built on GPT, Gemini, and Claude. It states that it is SOC 2 Type II compliant, encrypts data at rest with AES and in transit with TLS 1.2+, and does not use user data to train models, share it, or sell it. The service is for users aged 18 and over. Free includes 100 welcome credits; Pro and Studio list monthly credits but no prices.
