Korektor is a statistical spellchecker and (occasional) grammar checker released under 2-Clause BSD license and versioned using Semantic Versioning.

Korektor started with Michal Richter's diploma thesis Advanced Czech Spellchecker, but it is being developed further. There are two versions: a command line utility (tested on Linux, Windows and OS X) and a REST service with publicly available API and HTML front end.

The original OS X SpellServer providing System Service integrating Korektor with native OS X GUI applications is no longer developed, but do not hesitate to contact us if you are interested in it.
