Neuroscience-backed functional music for focus, sleep, and relaxation
Activity-based music and soundscapes for Deep Work, Creativity, Learning, Motivation, sleep, and relaxation, plus guided meditation and sleep sessions.
Patented audio modulation designed to enhance and synchronize brainwave activity, with adjustable neural effect levels you can dial up or down.
Higher-stimulation music designed for attention difficulties, backed by research supported in part by a National Science Foundation grant.
Infinite count-up timers, countdown timers, and interval timers that adapt to focus and break sessions.

The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
