Semantic Synchrony lets anyone edit and use a knowledge graph. A knowledge graph lets you express, connect and view any kind of natural language data -- "Who needs what from me by Monday?" "What have scientists said about global warming?" "What are some true stories that illustrate the value of being kind?"
A knowledge graph has as many uses as pen and paper: It can be a calendar, a notebook for studies, a web of quotations, a diary, an artist's sketchpad, a collection of overlapping hierarchies. Things in the graph are linked, and there is a search engine, and it integrates with your web browser.
If you choose, Semantic Synchrony lets you and others join your plans, your studies, your philosophy, your art -- any expressible thing. Sharing and privacy are both optional.
Surfing a knowledge graph can even be "integrated" with the experience of meditation. Using it can feel like creating and meditating on mandalas -- practical ones like grocery lists, or deep ones like notes about the nature of the self.
