Each of us has already been in the situation when he has found a mistake in his text. Mistakes do not have to be made just because of illiteracy. Just a little oversight and the mistake is made. If we do not find this mistake, there may be a very unpleasant situation for the author, especially if it occurs in a formal text such as thesis or curriculum vitae. That is why there are text correctors that help prevent mistakes.
The aim of this thesis is to design and implement a solution that will offer a quick check of Slovak text in the Chrome web browser for the user. The solution will be based on the existing tool called LanguageTool supporting Slovak language. In this tool of ours we will use the statistical method that can detect context-based mistakes.
