Delayed reading - how to set up the {Instapaper, Pocket, Readability} extension similar to the Kindle extension?

Question

Instagram

Good day everyone!
There is a need to read the articles behind the authorization form on an android device. It is desirable that the browser has an extension - poked a button, the article came to the device.
I tried Instapaper, Pocket, Readability - all three have an authorization form instead of an article in the application (that is, their extensions did not take the browser content, but sent a link to the server and their servers themselves tried to get the content). But kindle sends a normal article, i.e. it takes the content already from the browser...
Maybe I configured something wrong? :)
Tell me, please, where to look...
