LucaAIstein is opening to its first 50 customers. Three quick steps and your invitation request is on its way — the monthly platform fee is on us during the preview, and you pay only for the AI you actually use.
Step 1 of 3 — Who will learn?
Who will learn?
This helps us set up the right account shape — a family account with parental oversight, a personal account, or a classroom.
How billing works
No surprises — here is exactly what the Private Preview costs.
The $69 monthly platform fee is on us for the entire Private Preview — it appears on your invoice at $0.
You pay only for what you use. AI usage is metered per token from the first token and billed monthly at the provider's list price plus a 10% service fee — the exact rates are on the pricing page.
Card on file via Stripe, $0 charged at sign-up. After your invitation is accepted you'll receive a secure Stripe link; your card is only charged for the usage on your monthly invoice.
No allowances, no bundles, no free tokens. Quiet months cost nearly nothing; you can cancel any time and pay only for what was already used.
Request your invitation
This opens a prefilled email in your mail app — send it as-is or add anything you'd like us to know.
We reply within one business day (EU & US business hours) with your sign-in details and a secure Stripe link to put a card on file — $0 charged at setup.
Sign in at www.lucaexpress.com and open LucaAIstein from the app menu. For a child, the parental-consent step comes first — the tutor won't score or speak with a minor before recorded consent.
At 50 customers the preview closes — later requests join the waitlist for general availability.
