## What is Rusty?

Build a reading and math practice routine with Rusty, a voice-first AI learning companion for families with learners ages 4-12.

Short guided lessons pair spoken prompts with hands-on activities. Practice foundational skills, ask questions out loud, and give parents a clearer view of completed learning.

READING, PHONICS AND WORD PLAY
Practice letter sounds, sight words, word building, vocabulary, shared reading, sequencing and retelling. Read-aloud activities offer conservative feedback; Rusty does not claim to grade pronunciation or diagnose a reading level.

MATH YOU CAN SEE AND TRY
Explore counting, number paths, addition, subtraction, make-ten strategies, place value, patterns, arrays and groups through visual, tappable activities.

GUIDED VOICE LEARNING
Hear a prompt, try an answer, use a hint and take the next step. Rusty combines voice guidance with activity-based practice. Live voice requires an internet connection and parent setup. Activity-only practice remains available when voice time runs out.

PARENTS STAY INVOLVED
Adults create the account and manage learner profiles, goals, preferences and voice access. Parent controls and progress summaries help families follow practice grounded in completed activities. Children do not create their own accounts.

START WITH FREE PRACTICE
A parent account is required. Free includes one learner and a limited weekly voice allowance. Optional Premium and Family subscriptions provide additional voice access; Family supports up to four learner profiles. Current prices, allowances and renewal terms are shown in the app before purchase.

CLEAR DATA BOUNDARIES
Live voice lessons require the applicable parent notices and consent. Voice is processed to deliver the lesson. Rusty does not store raw lesson audio or full conversation transcripts. See the Privacy Policy for details on data use, parent controls and deletion.

Rusty's current library covers a focused set of foundational reading and math skills, not a full curriculum for every age. Rusty is a practice companion, not a school, diagnostic assessment, or replacement for a teacher or specialist.

As someone who has used AI for years, I know I rely on it too much. Rusty helps me stay sharp and not so dependent.

### 5/5 — Great

*2026-06-26*

Onboarding was amazing and training was good. I feel after a month or two I might adapt to the difficulty so they should add progressive difficulties.

**Developer response:** Thanks for the review, we are adding adaptive training as well as levels and new training modes in the coming updates!
