How can we help?

Because everything else is built on them. Before advanced subjects unlock, LucaAIstein asks you to genuinely master Reading, Writing, and Arithmetic — and that gate is immutable. No learner, parent, teacher, or administrator can override it; neither can we.

A "not yet" is never a dead end. The tutor always shows what you've mastered, what remains, and the next step to take. And learning itself is never blocked — only the unlock of advanced subjects waits.

That's Socratic teaching, and it's deliberate. Reasoning you build yourself is reasoning you keep. When you're stuck, the tutor narrows the question rather than handing you the answer — the destination is a mind that can get there alone.

Continuously and invisibly, inside the conversation itself. The tutor observes six things while you work: accuracy, fluency and speed, reasoning, struggle (productive versus unproductive), consistency, and retention. There is never a standalone test — and every number a parent or teacher sees traces back to real recorded events.

That's a retention check. Mastery means you still know it later, so the tutor quietly revisits material days or weeks after you learned it. Passing those invisible re-checks is part of what "mastered" means here.

Because productive struggle is where learning happens. The tutor deliberately lets you wrestle with a problem while the struggle is doing you good — and steps in when it stops being useful. It watches the difference in real time; struggle is one of the six metrics it tracks.

When you show sustained strength at a sub-skill — say, fluent arithmetic — the tutor may offer one gentle enrichment invitation, such as competition math. It's an invitation, not a verdict on your talent. It changes nothing about your gate, grades, or account; you can dismiss it; and it won't nag — invitations are frequency-capped.

During the Private Preview, invitations may be unavailable until our independent fairness review completes.

During the Private Preview the tutor teaches in English first. (This website speaks English, French, German, Spanish, and Portuguese.)

Everything. Every lesson, every question asked and answered, every result — and the evidence behind it: a trajectory for each of the six metrics, a mastery map showing what's conquered, in progress, and still locked, and your child's actual work samples.

Oversight is guardianship-scoped: you see your own learners, and only your own learners.

It's the one thing a parent cannot do — by design. If the foundations gate could be lowered, "mastered" would mean nothing. What you can always see is precisely what remains and the path there: the tutor frames every "not yet" with the next step.

During the Private Preview, unlock decisions are additionally conservative while independent expert calibration completes. Learning is never blocked — only the unlock of advanced subjects waits.

Because we won't show a number we haven't independently verified as fair. The grade-level estimate is anchored to a named external standard (for example CCSS/Lexile for reading), always shown as an uncertainty band, and always labeled "tutor estimate, not a standardized test."

It appears only after an independent subgroup-fairness review passes — so during the Private Preview it may show as unavailable. That's deliberate, fail-closed honesty. It never influences the mastery gate either way.

Scores, learning events, and their provenance — the record needed to prove mastery with evidence. Consent history is kept as an append-only ledger.

What it does not store: your Personal Library content (books stay on your device) and handwriting photos (the image is converted to a scored work sample on the device itself and never uploaded). And before parental consent is on record, a minor cannot be scored, recorded, or spoken to at all.

Yes — once you record voice consent for them. Voice supports read-aloud, dictation, and pronunciation practice, and it's adaptive: it speaks when it genuinely helps, and an early reader facing text they can't yet decode is exactly when it fires. If the connection drops, the lesson continues in text. Voice usage is metered and billed at the per-token rates on the pricing page.

The tutor adjusts celebration and game-like intensity automatically — up when it motivates, down when it distracts. Your cap is a hard ceiling on that intensity, and 0 disables gamification entirely. Whatever you set, gamification never affects mastery scoring or the foundations gate.

Yes. You can cap their frequency or disable them completely in parent settings. Invitations are never consequential — no effect on the gate, grades, or billing — so switching them off costs your child nothing.

Every parent-facing number traces to a real recorded event in your child's actual activity — nothing is fabricated or interpolated into existence. Anything we can't yet stand behind, like the grade estimate before its fairness review, shows as unavailable rather than as a guess.

It presents every credible perspective with its evidence and renders no verdict. Only approved content bundles are served. The goal is a learner who can weigh evidence — not one who inherits a conclusion.

No. The classroom view is scoped to your own class, following a FERPA-style boundary — a teacher never sees another class's learners.

Per-student evidence for your own class: metric trajectories, mastery maps, and work samples — the same evidence surface parents see, scoped to your students.

The educator surface for the shared curriculum catalog: provenance for every item, its copyright posture, and a review queue. The tutor serves only approved content bundles, and curation is how content gets approved. Access is teacher-scoped.

No — there is no teacher or administrator override, and that's the point. What you can do is see exactly which foundation skills remain and target them. The gate opens the moment mastery is genuine.

The monthly platform fee is on us during the Private Preview. You pay only for what you use: AI usage is billed monthly at the provider's list price plus a 10% service fee — metered from the first token, with no allowances or bundles. Current rates are on the pricing page.

Simply and transparently. When your account is set up you put a card on file via a secure Stripe link — $0 is charged at sign-up — and once a month you receive one invoice for exactly what you used. Because the monthly platform fee is complimentary during the Private Preview, your invoice is usage only: the provider's list price plus our 10% service fee. Rates are published on the pricing page, and you can cancel any time.

The Private Preview is invitation-based and limited to the first 50 customers, first come, first served. Once those places are taken, new requests join the waitlist, and we'll be in touch when general availability opens.

Usually within one business day. The team provisions accounts during EU and US business hours and replies with your sign-in details and a secure Stripe link to put a card on file ($0 charged at setup).

Yes — the sign-up wizard asks who will learn and how many learners; choose a team there and give the count. For organizations, an administrator receives and assigns the accounts, manages roles, and becomes the contact point for support and privacy requests.

No — LucaAIstein runs in your browser. Sign in at www.lucaexpress.com and open LucaAIstein from the app menu; after sign-in, the direct link is www.lucaexpress.com/lucaaistein/index.html.

A few things, honestly and on purpose: grade-level estimates and pathway invitations may show as unavailable until independent fairness reviews pass; advanced-subject unlocks stay conservative while expert calibration completes; the tutor teaches in English first; and voice — like all AI usage — is billed per token at the rates on the pricing page. We would rather ship the honest version than the impressive one.

Nothing that touches your child. The system fails closed to the most protective default: a minor cannot be scored, recorded, or spoken to by voice until a parent or guardian's consent is on record. Age is captured at signup, so the protection applies from the first moment.

Yes, at any time. Consent history lives in an append-only ledger — grants and revocations are both permanently recorded — and a revocation takes effect the same fail-closed way consent gates everything else.

No. The photo is read (OCR) on the device itself and becomes a scored work sample; the image is never uploaded. Servers store scores and provenance — not the raw picture.

No. The Personal Library is local-first: your books and documents stay only on your device, serve as reference during lessons, and never affect the mastery gate.
