Sentence Builder

A calm, errorless sentence-building system built for one learner.

A tablet screen showing a photo of a young man throwing a ball on the left, and columns of picture tiles on the right for building the sentence "He is throwing a ball."

What the Sentence Builder is

The Sentence Builder is ALPINE AI's first product in daily use. She looks at a photo, then builds a sentence about it by tapping picture tiles — one column per word. There is no score on her screen, no timer, and no way to "fail." It runs on a locked-down Android tablet at home, paired to a private dashboard her care circle can read.

It is not a commercial product. It was built for her, by her family, working with her speech-language pathologist (SLP) — and it is shared here so the people supporting her can see exactly how it works.

Five design principles

Every choice in the Sentence Builder — the visuals, the pacing, the feedback, the curriculum — is held to the same five commitments.

Predictability over novelty

The app never changes the pack, the pace, or the rules on its own. Nothing surprises her.

Clarity over complexity

One sentence frame, one new grammar target at a time. No hidden layers, no jargon on her screen.

Sensory-calm over stimulation

No scores, no timers, no competitive games. Quiet, gentle rewards instead of flashing excitement.

Self-paced over timed

She moves at her own speed. There is no clock counting down and nothing to rush her.

Literal over abstract

No metaphors, no idioms, no implied meaning — everything on screen is exactly what it says.
