Słownik Ortograficzny polski is a comprehensive spelling checker for the Polish language. It allows users to check the spelling of over 2.3 million words with their inflections. Upon entering a word in the search field, the application checks the spelling and suggests any necessary grammatical corrections. The list of displayed words shows only the correct ones. The dictionary does not require an internet connection to function.

The application has a large vocabulary, suggests proper spelling, explains homophones (e.g., lód - lud), and provides explanations for selected abbreviations. It works offline, and its interface is easy to use and fast.

For users with suggestions, problems, or questions, they can contact the developer via e-mail. Feedback for missing words or phrases is also welcome.
