In the last months we released under our brand name the web vocalization service. This service is able to read your site only adding a link/form on your pages. In the next days you can find on our site the various pricing, initially only three version will be available: Free (with advertising), Basic and Plus.
We have in development some platforms integration too, for now Wordpress (soon available on this blog obviously) and Drupal, in the next months some other platforms will be take in care (if you need some specific platform integration does not hesitate to ask).

Let me to know your feedback.
