Word River

Word River is a mobile app that lets caregivers record each word a toddler says, as well as signed and gestural forms, using a few taps with one hand. The app stores these captures and aligns them with speech‑language standards, marking when a word is fully mastered and highlighting emerging milestones. Weekly summaries generated by an AI trained on speech‑language best practices provide actionable tips written in an encouraging tone, while progress charts and shareable milestone cards visualize vocabulary growth.

The tool is aimed at busy families who want to monitor their child’s speech development without extensive manual tracking. It incorporates input from speech‑language pathologists and real families, offering features such as clear milestones, personalized AI insights, and caregiver sharing. Privacy is emphasized, with data protection policies that keep user information under the family’s control.
