Tagger is a free Chrome extension developed by Jeremías Pérez. It falls under the category of Browsers, specifically Add-ons & Tools. This extension allows users to create Hypothes.is tags directly from mindmap nodes in Mindmeister.

With Tagger, users can easily create tags by simply clicking on the pin icon next to a node in their Mindmeister mindmap. These tags can then be used to annotate web content using Hypothes.is, enhancing the user's mindmap with additional information and insights.

Tagger offers a seamless integration between Mindmeister and Hypothes.is, enabling users to enrich their mindmaps with annotations from the web. This extension is a valuable tool for those who rely on mindmapping for organizing and structuring their thoughts, as it allows for easy integration of web-based information.
