Hungarian grammar tools
These tools apply the same rules explained in the guides, and they show their working: every result says which rule produced it and flags the cases where Hungarian has to be memorised rather than calculated. They run entirely in your browser.

Hungarian case quiz

How reliable are the results?
The number and time converters are exact: Hungarian numerals and clock expressions follow closed rules. The suffix builder and conjugator are rule-based and correct for regular words; for words whose forms are lexical (lowering stems like ház → házat, irregular verbs like eszik) they either use a built-in word list or tell you clearly that the form must be checked. We would rather flag uncertainty than show a confident wrong answer.
If you find a wrong result, please report it with the word you typed.
