Endel

Endel, developed by Endel Sound GmbH of Berlin, operates a cross-platform ecosystem of AI-powered apps that generate personalized, functional soundscapes intended to help people focus, relax, sleep and stay active. Its patented technology generates audio in real time and adapts to inputs such as the user's movement, time of day, weather, heart rate and location, with each soundscape paired to a generative visual. The core generative engine, referred to as Endel Pacific, is built on principles including circadian rhythms, the pentatonic scale and sound masking.

The product is available on iOS (including a standalone Apple Watch app), Android, macOS, a web player, Apple TV and Amazon Fire TV, and as an Amazon Alexa skill that works with Echo devices, Fire Tablets, Fire TV, Alexa Auto and Alexa Routines. Beyond endlessly generated Soundscapes, the app offers timed Scenarios directed at specific activities (for example meditation, wake-up, anxiety relief, tinnitus relief and ASMR) and an Autoplay mode that selects a soundscape based on the user's state. Endel also distributes non-adaptive albums, singles and playlists on streaming platforms, including collaborations with artists such as James Blake, Grimes, Alan Watts recordings and Ta-ku.

The company positions the category it addresses as "functional sound" and funds peer-reviewed research to validate its claims, citing studies and Experience Sampling Method surveys reporting increases in concentration and reductions in stress relative to generic playlists.
