First: many many thanks to David - I have just found a gravestone (and date of death) that I have been looking for for a long time!
Second: the site does have an Englisih interface -- upper left hand corner of the Hebrew, site, or the following link: https://gravez.me/en/. However the site doesn't translated or transcribe names, so, you have to know the Hebrew spelling of the name you're searching for.
Once you've got the name - you get all the information (except for the name) in English.
And the spelling has to be exact - the search engine does not work like a google search.
So, when you ask for help in transcribing, make sure to ask for alternative spellings.
And if it's common name - the more details you have, the better.
