Just click on extension button at any website that you want to use. If it wasn't supported send request for that site, and I will be adding support for it.
Also I'm working on independent solution for supporting all websites. Right now there is a backend that crawls supported sites for title and descriptions.
edit: also sorry for not mentioning that supported sites, I was too excited while sharing this at HN.
