Adaptive AI soundscapes for focus, relaxation, sleep, and activity
Endel generates sound on the fly and adjusts it to inputs like time of day, weather, heart rate, and location, so the audio shifts with your state instead of looping a fixed track.
Dedicated Focus, Relax, Sleep, Activity, ADHD, and autoplay modes cover the main use cases, each with its own sound palette and generative visual.
Generate endless soundscapes directly on the wrist without an iPhone nearby, using biometric and light data for deeper personalization.
iOS, Android, Apple Watch, Amazon Alexa, Apple TV and Fire TV, macOS/desktop, and a web player let you keep the same sound system across devices and rooms.

Turn plain text into diagrams, infographics, and presentation-ready visuals.
Paste or import your text and Napkin generates infographics, diagrams, flowcharts, mind maps, and data charts that fit your content.
Napkin Slides collaborates with you to turn ideas into complete, ready-to-present decks rather than static images.
Adjust colors, fonts, layouts, and icons, reshape individual elements, and match your brand — nothing is locked after generation.
Export visuals as PPT, PNG, PDF, or SVG and drop them into PowerPoint, Google Slides, Keynote, Notion, or any tool you already use.
