A 40-word sentence is hard for two different reasons: you can't see its structure, and you can't get it out of your mouth. Chunkly takes both — it splits the sentence into thought groups you can actually see, then scores you reading it back, word by word.

A 40-word sentence splits into thought groups, each labelled with its role. One tap strips it to the bare skeleton.
The model reading pauses between thought groups — the same boundaries you just saw, so the structure becomes a rhythm.
Build the sentence from the end, one thought group at a time, until the whole thing flows. Tap record and say it back — recording stops by itself.
Scores for accuracy, completeness and fluency — with every word colour-coded and the problem traced to the exact phoneme.
25–45 words with two levels of nesting, across nine grammar topics — relative clauses, subjunctives, inversion, ellipsis. Split into thought groups, each role labelled, the skeleton one tap away.
