Welcome to Semantic Synchrony!

The experience | Why

Semantic Synchrony lets anyone edit and use a knowledge graph. A knowledge graph is what Google, Siri, Alexa and others use to answer questions about the world. Semantic Synchrony, however, is easy: There are only about 25 commands you need to know, and the entire introductory video course takes less than 45 minutes.

Some essays on the benefits of personal knowledge mapping have been collected at smsn-why.

The software | How

Disclaimer (and good news!): Semantic Synchrony is evolving.

Installing it

Semantic Synchrony is easy to install: build the standalone server JAR, create a configuration file, start the server, and connect with Emacs. Your notes are stored as plain text files that can be version-controlled with Git.

Using it

This brief howto explains everything you will need to know to use Semantic Synchrony. It assumes no prior familiarity with Emacs, knowledge graphs, or any other technology. (For a brief list of critical commands, or the complete list, see the smsn-mode wiki.)

Hacking it

Please see the invitation to coders.
