Its most prominent feature is that it solves captchas, those little picture riddles that are put on webpages to verify that the page is used by a human and not an automatic system, a so-called robot. These pictures contain text that are intentionally heavily distorted so that an average OCR can't figure it out, thus if the text is correctly entered it is quite sure that a human is in front of the webpage. The mass-introduction of this concept ruined the accessibility of many otherwise accessible webpages. There exists an alternative since then, the audio captcha (a heavily distorted voice message which you have to decipher), but they are often so distorted that they simply can't be understood at all. Webvisum does a really good job on those little image "bastards", it solves at least 9 out of 10 of them in my experience. But the extension doesn't solve the captchas on the host computer, but rather sendsthem to the server and simply retrieves the solution. And from this fact comes the problem. This service needs registration either through an invitation by another user or through introducing yourself and asking approval to use the service. This has a serious reason: the service provider wants to minimize the risk of abusing the captcha solving service by spammers. That's why I don't think it's legally possible to implement the service in another software without the permission and strong cooperation of Webvisum developpers. It seems Webvisum is not really developped actively an more, so cooperating with them has a very faint chance. Other than that implementing this service on our own would be very difficult technically too, because the extension (which is just the client) is closed source. In the best case if the developpers fully cooperated with NVDA team and approved the porting of the service, I still don't think it would be a good idea to integrate it into the screen reader itself, it could be a great candidate for an addon instead. All in all I am afraid this will be a "won't fix". Changes: Changed title from "webvisum should be intigrated with n v d a" to "webvisum should be integrated into NVDA"
