Mastery-based homeschool · grades K–5

A few focused hours. The rest is childhood.

A calm, mastery-based learning home for K–5. Kids do two to three focused hours with an AI coach who never just hands over the answer — then close the tablet and go be kids.

Welcome back

Parents sign in — kids just open the app and learn.

Made for the way your family learns

Full-time homeschool, a co-op two days a week, or a hybrid schedule — Rascals fits around whatever your week actually looks like.

Mastery, not seat-time

Lessons unlock as kids actually master them — and the tough ones come back over several days to lock them in, never grinding the same thing three times in a row.

An AI coach, done right

Otto gives hints and asks questions but never the answer. Every chat is logged for you to read. No idioms, no autoplay, neurodivergent-friendly by default.

Then real life

Two to three focused hours on the tablet — add more lessons if you want. Collectible Rascal Cards and forgiving streaks keep kids coming back, then they close it and go play.

How it works

Set it up once — then it runs your school day.

1
Place each kid

A quick adaptive check finds the right starting level per subject — a kid can be grade 4 in math and grade 2 in reading. Or just set it yourself.

2
Auto-built daily plan

Every school day, Rascals builds a balanced lesson queue from your subjects and pace. You can plan the year, or let it run.

3
Master & reward

Kids work the queue with Otto's help, earn Rascal Cards, and you get a Kentucky-ready attendance + mastery record automatically.

One app instead of six

Most families stitch together five or six tools. Rascals is the one place the whole day lives — every subject, all in one rhythm.

Why I built this

Hi, I’m rez0.

I’m an AI and security researcher — and a dad of three. I want my kids learning at their own pace and actually mastering things, without being stuck on a screen all day. I couldn’t find one tool that did that: most mean stitching six apps together and trusting an AI you can’t see into.

So I built Rascals — a Socratic coach that never just gives the answer (and whose every word you can read), mastery instead of seat-time, and a clear stop so the rest of childhood gets the rest of the day.

Questions parents ask

Is the AI safe for my kid?

Otto never gives answers — only hints and questions — uses no idioms, and flags concerning messages. Every conversation is saved for you to read in the parent console. Audio is off by default and there's no autoplay or ads.

Do my kids need their own logins?

No. Parents have the login; kids just open the app and learn. You can set an optional 4-digit passcode per kid so siblings can't hop into the wrong profile.

How much screen time is this?

It's designed around a focused two-to-three-hour block, then done — though you can add more lessons if you want. Mastery, not seat-time, decides when a lesson is finished, so kids aren't padding hours on a screen.

What's the difference between Basic and Pro?

Both include everything for the kids — all subjects, the AI coach, lessons, cards, story library. Pro ($20/student) adds the AI Parent Dashboard: coloring-page and worksheet generators, plus an advisor chat that knows your kid's progress.

Does it help with homeschool paperwork?

Yes — attendance and mastery roll up automatically into a Kentucky-ready scholarship report and letter of intent. More states are on the way.

Give them the hours that count.
