Analytical engine running above for filtering new feeds

[jbionic2016]

Hi there,

Thanks again for your marvellous RSS service.

There are some RSS filter engines already available, such as SiftRSS, grepfeed.sigwait.tk etc.
But they certainly lack certain functionality.
I just thought it would be wonderfull if politepol could also analyse and determine the language of a new feed
take for instance the following RSS: https://libgen.st/rss/index.php
it has some ebooks in English, some in German, some in Polish. So if a subscriber can't read in all those languages, then perhaps it is better to filter some feeds out

Best regards
