Hascheck started as an e-mail embedded service in 1993, at first only for the staff of the Faculty of Electrical
Engineering and Computing in Zagreb, but in March 1994 it became a public service, primarily dedicated to the
Croatian academic community. In the summer of 2003 the e-mail service was converted into a web service available
at http://hascheck.tel.fer.hr/. With the web interface, Hascheck became a service adopted worldwide. In the last ten
year of operation, the service was used by more than 450 000 users (HTTP cookies) from 124 IP-domains (121
country and 3 generic top-level domains). They have sent more than 7.2 million texts to proofreading, which formed
a corpus of more than 1.8 billion tokens (Gtokens).
