Meet Rusty, a voice-first AI learning companion for families. Short daily quests support foundational reading and math practice at home or on the go. Rusty combines guided voice lessons with hands-on, on-device activities. Parents manage learner profiles, goals, voice access, and progress. SHORT DAILY QUESTS Rusty keeps each lesson focused: hear a prompt, try an answer, use a hint when needed, and move on. Completed activity results help choose useful next steps without turning practice into a test. READING THAT INVITES PARTICIPATION Practice letter sounds, sight words, word building, vocabulary, shared reading, sequencing, and retelling. Read-aloud activities use conservative feedback and do not claim to grade pronunciation or reading level. HANDS-ON FOUNDATIONAL MATH Explore counting, number paths, addition, subtraction, make-ten strategies, place value, patterns, arrays, and groups with visual, tappable activities. Rusty's current library is a focused set of foundational reading and math skills, not a full curriculum. VOICE AND ON-DEVICE PRACTICE Use voice time for live, guided lessons with Rusty. When voice is not available, learning can continue with app-owned activities that run without a microphone or AI provider. A one-time First Lesson pass with 10 total voice minutes, plus monthly Premium and Family plans, is available through in-app purchase. PARENT-MANAGED BY DESIGN A parent account is required. Parents create and manage learner profiles, choose goals and preferences, control voice access, and view progress summaries grounded in completed activities. The Family plan supports up to four learner profiles. CLEAR DATA BOUNDARIES On-device activities do not send learner information to an AI provider. During a live voice lesson, voice data is processed to deliver the lesson. Rusty does not store raw lesson audio, full conversation transcripts, photos, or free-text learner answers. See the Privacy Policy for details. ALSO INCLUDED FOR GROWN-UPS Classic Brain Training remains available behind a grown-up check. Rusty is a practice companion, not a school, full curriculum, diagnostic assessment, or replacement for a teacher or specialist.
