Annotator is a JavaScript library for building annotation systems on the web. It provides a set of tools to annotate text (and other content) in webpages, and to save those annotations to a remote storage system. For a simple demonstration, visit the demo or download a tagged release of Annotator from the releases page and open demo.html.

Annotator aims to provide a sensible default configuration which allows for annotations of text in the browser, but it also has a library of plugins, some in the core, some contributed by third parties, which extend the functionality of Annotator to provide:

• serialization: "store" plugins save your annotations to a remote server. The canonical example is the Store plugin_ which ships with Annotator.
• authentication and authorization: the Auth plugin_ and Permissions plugin_ allow you to decouple the storage of your annotations from the website on which the annotation happens. In practice, this means that users could edit pages across the web, with all their annotations being saved to one server.
• rendering: the Markdown plugin_ renders annotation bodies as Markdown.
• storage of additional data: the Tags plugin_ allows you to tag individual annotations.

For a list of plugins that ship with Annotator, see the plugin pages of the Annotator documentation. For a list of 3rd party plugins, or to add your plugin, see the list of 3rd party plugins on the wiki.
