Educator guide
You teach. It proves.
LucaAIstein is an adaptive Socratic tutor that works alongside your teaching — and an evidence engine that shows you, for every student in your class, exactly what is mastered, what is in progress, and what to do next. This guide covers everything an educator needs: your classroom view, how to read the evidence, how the mastery gate behaves, and how to curate the curriculum your students learn from.
01
What LucaAIstein is — and is not
LucaAIstein teaches the way a great tutor does: it asks rather than tells. Every lesson is a Socratic dialogue that builds reasoning step by step, adapting to the learner in front of it. While the conversation happens, the tutor quietly measures understanding across six dimensions — no quizzes announced, no test days, no performance theater.
For you, that measurement becomes something rare: continuous, honest evidence of what each student actually understands — not what they crammed for on a Thursday.
It is
- An adaptive Socratic tutor — it asks, guides, and lets productive struggle happen on purpose.
- An evidence engine for you — every number traces to a real recorded moment of learning.
- A patient extra pair of hands — it drills, re-checks, and revisits so your class time can go where judgment is needed.
- Curated — learners only ever see content from the approved curriculum catalog.
It is not
- A replacement for the teacher. It informs your judgment; it never replaces it.
- A grading machine. There are no letter grades — mastery is shown as evidence, not a score to argue over.
- An arbiter of contested questions. On topics where credible perspectives differ, it presents each perspective with its evidence and renders no verdict.
- A surveillance tool. You see learning evidence for your own class — nothing more, from no one else's.
02
Your classroom view & the class boundary
When you sign in, you see your class — every learner assigned to you, each with their evidence trajectory, mastery map, and work samples. It is the whole class at a glance, and any one student in depth.
The class boundary is strict. You see your own class and only your own class. A teacher can never see another class's learners — not their names, not their progress, not their work. The boundary follows a FERPA-style isolation model and is enforced by the system's design, not by a policy document. Parents, likewise, see only their own children — a learner's evidence is visible to their own parent or guardian and to their class's teacher.
If a student changes classes, access follows the roster your administrator maintains — there is nothing for you to configure, and nothing you can accidentally over-share.
03
Reading a student's evidence
Assessment in LucaAIstein is continuous and invisible: it lives inside the dialogue itself and is never a standalone test. That means the evidence you see reflects how a student actually thinks over weeks — not how they performed under pressure on one morning.
Each student's understanding is measured across six metrics:
Accuracy
Is the answer right? The foundation — but deliberately only one sixth of the picture.
Fluency
How quickly and smoothly does the student work? Mastery is not just correctness; it's ease.
Reasoning
Can they explain why? Socratic dialogue makes the thinking visible, not just the result.
Struggle
Productive or unproductive? Productive struggle is allowed on purpose — it's where learning happens. Spinning without traction is flagged instead.
Consistency
Does the skill hold up across days and contexts, or does it come and go?
Retention
Invisible spaced re-checks return days or weeks later. What survives time is what's truly mastered.
The mastery map
Every student has a mastery map showing each skill as conquered, in progress, or locked. It is the fastest way to see where a student stands and what the tutor is working on with them right now.
Work samples
Alongside the metrics you'll find real artifacts — moments from dialogue, written work, and scored samples from Analog Practice. Every parent- and teacher-facing number traces back to these real recorded events. Nothing is fabricated, ever; when evidence is thin, it shows as thin rather than being papered over.
Grade-level estimates
Where available, a per-track estimate anchored to a named external standard (for example CCSS/Lexile for reading) is shown as an uncertainty band, clearly labeled "tutor estimate, not a standardized test." It never influences the mastery gate. During the Private Preview this estimate may show as unavailable — it only appears after an independent subgroup-fairness review passes, and we deliberately fail closed until then.
Using evidence in conferences
The evidence view is built to replace the vaguest sentence in education — "she's doing fine" — with something you can point at:
- Open with the mastery map. Conquered, in progress, locked — parents grasp it in seconds, and it frames the conversation around growth instead of grades.
- Show one trajectory, not six. Pick the metric that tells this student's story — a retention curve bending upward, or accuracy that's high while fluency lags.
- Ground it in a work sample. One real moment of the student reasoning is worth more than any chart.
- Name the next step. Every view answers three questions: what is mastered, what remains, and what comes next. End the conference on the third.
04
The mastery gate in your classroom
Before advanced subjects unlock, every learner must genuinely master the Three R's — Reading, Writing, Arithmetic. This is the foundation of the product, and it has one property that surprises educators at first:
The gate is immutable. There is no override — not for the learner, not for a parent, not for a teacher, not for an administrator. This is not a missing feature; it is the product's core promise. When any adult can waive the foundations, the foundations stop being real. Because no one can bend the gate, its word means something — for every student, equally.
"Not yet, and here is the path"
The gate never issues a bare refusal. Every "locked" state comes with three things: what the student has already mastered, what remains, and the concrete next step. That framing is deliberate, and it is your best teaching instrument:
- Treat the path as your intervention plan. The gate names the exact sub-skill that remains — that is your small-group lesson, tomorrow.
- Say "not yet" the way the tutor does. Not a judgment, just honest information with a direction attached. Students absorb the framing adults use.
- Don't promise an unlock date. Mastery arrives when it arrives; promise the path and the support, never the calendar.
- Celebrate unlocks loudly. Because they can't be granted, they can't be discounted. An unlock is earned proof, and students know it.
During the Private Preview, unlock decisions are deliberately conservative while independent expert calibration completes. Learning is never blocked — students keep working, practicing, and building evidence the whole time; only the unlock of advanced subjects awaits calibration.
05
The Curriculum Curator
Educators get a surface no one else has: the Curriculum Curator, where you help curate the shared curriculum catalog that every lesson draws from. The tutor serves only approved content bundles — nothing reaches a learner without passing through this process.
What curation involves
- Provenance. Every item in the catalog records where it came from and who reviewed it. No anonymous content, no untraceable claims.
- Copyright posture. Each item carries an explicit statement of its usage rights. Material without a clear posture does not enter the catalog.
- The review queue. New and updated material waits in a queue for educator review before any learner can see it. Approval is a deliberate act, never a default.
Settled facts and contested topics
The catalog distinguishes two kinds of content, and curating well means marking which is which:
- Settled facts are taught as facts. Arithmetic, spelling, the boiling point of water — the tutor states them plainly and checks mastery.
- Contested topics — questions where credible perspectives genuinely differ — are handled differently by design: the tutor presents every credible perspective with its evidence and renders no verdict. The student learns to weigh evidence and reason; the conclusion stays theirs to reach.
When you review material for a contested topic, your job is completeness and fairness of the perspectives presented — not picking a winner. If a credible perspective is missing, add it; if a perspective is presented without its evidence, send it back.
06
Analog Practice for homework
Some of the best homework has no screen in it. Analog Practice connects real paper books and real handwriting to the evidence system, so offline work counts:
- Honor-system reading log. Students log the real books they read. It is honor-based on purpose — the point is the habit, and retention checks in dialogue naturally reflect real reading anyway.
- Read-aloud. Reading practice from physical books, connected back to the learner's fluency picture.
- Handwriting capture. A student photographs their handwritten work; the photo is converted to text on the device itself and becomes a scored work sample. The image never leaves the device — servers store the score and its provenance, never the photograph.
Two things to know before assigning it: Analog Practice is consent-gated — for minors, a parent or guardian must have granted consent before handwriting capture works. And it is additive, never required — it can enrich a student's evidence but a student is never penalized for not using it. Design homework so Analog Practice is a bonus lane, not a prerequisite.
In practice: assign the real book and the written exercise as you normally would. Students with consent capture their work and it appears among their work samples; students without simply bring the paper to class, as ever.
07
Voice in the classroom
The tutor can speak and listen — read-aloud, dictation, and pronunciation practice. Voice is adaptive: it engages only when it is pedagogically valuable, such as an early reader facing text they can't yet decode. It is a teaching tool, not a novelty.
Consent comes first, and the system fails closed. The tutor will not speak with, record, or score a minor by voice before recorded parental consent exists. There is no educator override for this — a student without voice consent simply works in text, automatically. Before planning a spoken-word activity for the class, check with your administrator which students have voice consent on file.
- It degrades gracefully. If the connection falters, the session continues in text — a lesson never dies mid-thought.
- Preview note: voice minutes are metered and billed as part of normal usage. For a whole-class activity, plan short, purposeful voice moments rather than hour-long sessions.

Onboarding a class during the Private Preview
LucaAIstein is in Private Preview (since July 18, 2026) — invitation-based, limited to the first 50 customers. The monthly platform fee is on us during the Private Preview, and you pay only for what you use: AI usage is billed monthly and metered from the first token, with no allowances or bundles. Current rates are on the pricing page. Classroom accounts are provisioned through your organization's administrator, who requests the invitation, assigns roles, and remains your contact point for account changes.
- Your administrator requests an invitation. They use the sign-up wizard, which asks who will learn and how many learners and sends the request to the team. No administrator yet? Request an invitation yourself and the team will help you set one up.
- The team provisions and replies with sign-in details and a secure Stripe link to put a card on file ($0 charged at setup) — usually within one business day, EU & US business hours.
- Everyone signs in at www.lucaexpress.com and opens LucaAIstein (🧠) from the app menu.
- Parents complete consent for minors first. The tutor will not score, record, or speak with a minor before recorded parental consent — it fails closed. Build consent into your first-week checklist, before the first lesson.
The Private Preview is invitation-based and limited to the first 50 customers, first come, first served. Once the 50 are taken, new requests join the waitlist for general availability. If you want your class in the preview, have your administrator request an invitation soon.

Preview candor: the tutor teaches in English first during the Private Preview (the site speaks EN/FR/DE/ES/PT). Grade-level estimates and enrichment-pathway invitations may show as unavailable until independent fairness reviews pass — we ship the honest version, and fail closed rather than guess. Advanced-subject unlocks are conservative while expert calibration completes.
