Get started in minutes with just a few simple steps
A word appears with specific letters replaced by blanks. The AI strategically removes the letters most commonly misspelled in that word.
Fill in each blank with the correct letter. The cursor advances automatically, and each letter is validated in real time with green or red feedback.
After completing the word, see a breakdown of which letters are commonly missed. Words with errors enter your spaced repetition queue for future review.
Built with cutting-edge AI to make spelling practice effective and engaging
The AI does not remove letters randomly. It analyzes common misspelling patterns and removes the specific letters that students most frequently get wrong.
Your individual spelling history determines which letters are removed. If you always misspell the "ei" in "receive," those are the blanks you will see.
Start with one missing letter per word and progress to multiple blanks. The hardest mode shows only the first and last letters — can you recall the rest?
Switch between vowel-only blanks, consonant-only blanks, or mixed mode. Vowel mode is particularly effective for students who struggle with vowel patterns.
Detailed reports show which letter positions and patterns cause the most errors. Teachers can identify systematic spelling weaknesses across entire classes.
Hear the complete word spoken before and after filling in blanks. Connecting the full pronunciation to the partial visual trains phoneme-to-grapheme mapping.
Content automatically adapts to each student's level and ability
