This is excellent but discovery has too much friction. I've been looking for something like the google knowledge graph for personal or business use haven't been able to find anything pre-made and I'm far too lazy to build it myself with Cayley or Neo4j or _insert graph database here_. Has anyone heard of anything similar? Just want an easy way to search, and add entries to a graph database, hopefully with node-level permissions that can be applied. I feel like it would help everyone, so I'd assume someone other than Google would have made it already but I haven't found it... anyone up to the task so I can be lazy?
