There's this great tool to get you started on generating a JSON Schema: http://www.jsonschema.net/ . Just feed a sample JSON files and out comes out a JSON Schema that you can then tweak.

You can use Orderly. They have DSL for schema description and you can try it online.

You could try this one (XML ValidatorBuddy) which is actually an XML editor but it also supports JSON and especially JSON Schema editing. The editor is a Windows desktop application and can do auto-completion and syntax-coloring for JSON schema files. You can also validate your JSON files against JSON schema.

Check this demo one. It is at an early stage but you can already edit jSON documents with a schema constraint as well as design a Schema itself.
And here is an official thread about Schema-based JSON editor:

This isn't exactly something that'll help you with a 'schema', per se, but it's a visual way to navigate and manage JSON data.
