One tile per skill. One profile per student.

Every English phonogram lives on PhonoSpark's tile grid. Click to mark mastered, teaching, or not mastered for any student — and the rest of the app follows. Word lists, sentence generation, decodable passages, all tuned to what each student can do.

  • Numbers on each tile show how often it occurs in the dictionary
  • Halo'd tiles drive your "new words" target for the lesson
  • Mastered + halo = the closed whitelist sent to AI for prose
syllable-aware filtering

Match the lesson to the syllable patterns your student is ready for.

Teach ti/ger when you're ready to teach ti/ger, and do it from words with phonics patterns your student has already mastered. Allow as many or as few syllables per word as you want them to decode. And pick which syllable type you want in which position. Make it easy for your students and yourself.

  • CLOVER syllable-type matrix (closed / open / silent-e / Cle / etc.)
  • Position-specific syllable filtering
  • Watch your fair / new word totals adjust in real time

Teach one prefix, unlock a thousand words.

Phonics teaches your student to decode letters. Morphology teaches them to decode meaning. Mark re-, -tion, or -able as taught, and PhonoSpark pulls every word in the dictionary that carries it — word families, compound vocabulary, a reading ceiling that rises by the dozen.

  • Every productive prefix and suffix in English, grouped by meaning, not alphabet — negation, repetition, ability, direction…
  • Tile counts show how many dictionary words each affix unlocks
x-ray vision

See every word the way your student does.

Hover any word and PhonoSpark pops the full phoneme-grapheme decomposition — split by syllable, each tile labeled with the sound it makes. The same data that drives the rest of the app: 60,000 English words, 349 phonics rules, every spelling-pattern variation already classified.

  • Syllable types (closed / Cle / open / vowel team / silent-e / r-controlled)
  • Compound phonograms broken down into their constituent graphemes
  • Works on every word your student touches — no extra clicks
