Eccco is a Chrome add-on developed by app.eccco that offers a unique way to enhance your internet browsing experience. With Eccco, you can add comments to Instagram stories, Netflix content, and virtually anywhere else on the web. This add-on acts as an alternative version of the internet, allowing you to access additional information for any URL in a decentralized manner.

By using the "share with" feature available on any mobile device, you can unlock extra features for a specific URL. Currently, these features are primarily text-based, but the developers have promised that more exciting features are on the way. Eccco invites users to join them in being a part of the second layer of the internet, providing a new and interactive way to engage with online content.
