Action Text is for rich text editing which lets users create rich text formatted content. They can create the content through a WYSIWYG editor (Trix).
Action Text uses the Trix editor to allow for advanced text editing on a webpage in Rails. It also allows for the text produced to be saved as a RichText model which can be associated with a Rails Active Record model. The Trix editor can also handle complex things like links and images. Action Text will also take any attachments and store them via Rails Active Storage.
