When we created the tool for extract main article from a page, we wanted to get an entire article from an URL (URL taken from RSS feed) not only excerpt.
We tested 4 RSS to Kindle delivery services and all of these are non-intuitive and paid services. This is the reason for we want to build a better service for this need. Another problem it’s that the most of RSS feeds put on stream only an excerpt of article not entire article. For this reason we created a tool that you can use to extract the main article of a page.
We hope to announce soon an complete service that delivers valuable content on Kindle or another eBook reader.
