Genius: Web Annotator

Annotate every web page

You can install our Chrome Extension, so Genius is with you everywhere you go. If you don’t use Chrome, try our Bookmarklet.

Enable annotation on your own site

If you’re a publisher, you can install a simple line of javascript to Genius-activate your own site. Try it out:

<script async src="//genius.codes"></script>

If your site runs on WordPress, make your posts annotatable with our WordPress Plugin.

Share annotated pages with everyone, no extension needed

Put genius.it/ in front of any URL to annotate and read other Genius annotations on any page on the Internet. You don’t need to download anything!
