Early access for families

The AI tutor who remembers your child— and meets them where they are.

Mossbridge is a family-first K-12 tutoring platform built around an animated AI teacher who knows your child by name. After a child-friendly diagnostic, Moss places each learner at the right instructional level — not just the grade on their enrollment form — and works them up toward grade-level standards with encouragement, never embarrassment.

Reading with Avery, grade 4

How it works

Three steps. Then Moss knows your child.

We made the diagnostic feel like a chat with a kind teacher, not a test. Placement is honest. Lessons remember what your child tried last time.

  1. 01

    A friendly diagnostic

    In under 15 minutes, Moss chats with your child across reading, math, English, and vocabulary — no high-stakes test, no pressure to perform.

  2. 02

    Honest placement

    Moss places your learner wherever they actually are — third-grade reading at a sixth-grade level, or sixth-grade math that needs third-grade foundations.

  3. 03

    A tutor who remembers

    Every lesson carries forward — what your child got right, where they slipped, and how Moss teaches it back next time. Always addressed by name.

For parents

The dashboard your school never built.

Mossbridge is parent-pays because the things you see should be the things that matter: what your child learned, where they’re stuck, and what to practice this week. No district procurement features, no vendor pitches in your inbox.

Subjects

Five subjects. Every grade that matters.

Each subject has its own lesson arc with built-in checks for understanding. XP, badges, and daily goals sit on top — game-y for younger learners, a serious study loop for teens.

Safety & transparency

AI is always AI. Parents see everything Moss says.

The AI reasoning layer is fully separated from the user interface. Session logs are available to your family account — not to advertisers, not to districts, not to anyone you haven’t explicitly shared them with.

  • AI labelling, every screen

    Children never mistake Moss for a person.

  • No third-party trackers

    No ad networks, no data brokers.

  • Parent-readable transcripts

    See every line Moss said, and why.

  • One-tap data export

    Move or delete your family’s data at any time.

Transparency card

What Moss just said to Avery

[AI tutor] “Great try, Avery. ‘Disappointed’ is one answer — let’s look for an even better one. What word fits both sad and hidden?”
“Lonely.”
[AI tutor] “Beautiful. ‘Lonely’ carries the feeling without telling us. That’s inferencing.”

Every Moss prompt is labeled, logged, and visible to Avery’s parent.
