Why it is new

What exists today, and what this does differently

What is new

Per-question USDC tutoring exists in demos; a creator-cloned tutor with human escalation is an uncommon combination.

Closest things out there

ArcGPT (Arc testnet hackathon) charges per question in USDC and Nevermined sells per-query tutoring billing; Delphi clones experts offchain.

Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.

The pitch, ready

Turn your teaching into an AI tutor students pay per question, with you reviewing the hard ones.

Problem: Great teachers can only reach the students in their room, and students get generic chatbot answers that do not match how their teacher marks.

Solution: A twin trained on the teacher's own notes and conventions, hint first, with a confidence line that routes hard questions to the teacher for a premium, paid per question in USDC.

Why now: Small models make per question answers cost fractions of a cent, and stablecoin micro payments make cents per answer viable.

Market: Secondary school teachers and tutors, parents paying for extra help, and schools that want results evidence.

The ask: Pilot with ten teachers in two Lagos schools through a mock exam season.

Funding is never guaranteed. Check each program's rules.

BLUEPRINT

Why it matters and how it really works

The need

Good teachers are the bottleneck. Students need help at 10 PM before an exam, and the teacher they trust cannot answer forty messages a night. Generic AI tutors answer, but not in the teacher's method, and the teacher earns nothing from the extra reach.

What exists and what is new

Per-question tutoring payments already exist in demos: ArcGPT (an Arc testnet hackathon project) charges per question in USDC, Nevermined sells per-query billing for tutoring apps, and Delphi clones experts offchain. What this combines is less common: a tutor built from one named teacher's own materials, a confidence line that routes hard questions to that teacher for a premium, an exam lock, and opt-in results attested to the teacher's profile. Research verdict: rare, medium novelty; each piece exists somewhere.

The data it runs on

The teacher's notes, past papers, voice explanations and mistakes list (private, retrieval only); per-question payments; escalation records; opt-in mock results signed by a school officer. Student questions and identities stay private.

1.The mission

Let every great teacher reach far more students in their own voice, and be paid fairly for the questions that truly need them.

2.Why people can't resist it

It sounds like your teacher Answers use his method, his conventions and his phrases, hint first, so students learn instead of copying.

The hard ones reach a human Below a confidence line set by the teacher, the twin stops and routes the question to him. Students pay only if he answers.

Sunday review Twenty minutes a week to check flagged answers keeps the twin his, and each fix becomes a new worked example.

3.How it works for real

Ingest: Notes, past papers and transcribed voice notes are chunked and embedded into a private retrieval index per teacher.

Answer: A mid tier model (for example Claude Haiku or a similar small model via OpenRouter) answers with retrieved passages and a conventions sheet; a self check scores confidence.

Escalate: Below the teacher's threshold the question goes to an inbox; a voice or text answer is returned to the student and saved as a worked example.

Pay: Students or parents top up a Privy embedded wallet with USDC on Base or Solana; each question settles per call (x402 style) and a split sends the teacher his share.

Exam lock: Teachers set exam windows; questions matching a live paper are refused without charge.

Attest results: With student consent, a school officer signs class level mock results as an EAS attestation on the teacher's profile. Individual scores are never published.

4.Cost per use and pricing

A typical answer is about 3,000 input and 500 output tokens; on a small model that is roughly $0.002 to $0.01 per question (check current model prices). USDC transfers on Base or Solana are typically under one cent. At 600 questions a week and $0.10 each, gross is about $60 a week; model and gas costs are a few dollars, leaving roughly $42 to the teacher at a 70% share, plus premiums.

Per question $0.05 to $0.25

Students pay only for questions they ask; hard ones routed to the teacher carry his set premium.

Term pass $8 a term

Up to 150 questions a term for one student, sold to parents, with a weekly progress note.

School licence $40 a month

A department hosts several teachers' twins, with exam locks and results attestations signed by the school.

5.Growth loop

Students share the twin's link in class groups because it explains like their teacher. Teachers with attested results attract students from other schools, and other teachers ask how to build their own.

6.Risks and guardrails

Wrong answers: The twin can be wrong. Confidence routing, refunds on errors and the weekly review limit the harm, and answers cite the teacher's notes.

Cheating: Exam locks and hint first answers reduce copying, but cannot stop it. The teacher sets the rules and sees flagged cases.

Minors and privacy: Most users are teenagers. Parents control top ups, chats are private, and nothing about a student goes onchain.

Employment terms: Some schools claim rights to teaching materials. Teachers should check their contract before selling a twin built from school work.

Payments friction: Many students lack crypto wallets; parents top up through a card or local on ramp, and USDC stays an implementation detail.

8.Where this is going

Now
One physics teacher in Lagos answers the questions that need him and earns from the rest.
Next
Whole departments run twins, and parents buy term passes instead of costly private lessons.
Later
Teachers carry attested results between schools and countries, and the best explanations reach students anywhere.
The world it changes
Great teaching stops being limited by hours in the day, and the people who teach well are paid for how far their teaching goes.

Costs and tools are estimates at the time of writing. General information only, not legal or financial advice.

Why own Tutor Twin

Tutor Twin turns your teaching materials into an AI tutor students pay per question, routes the hard ones to you at a premium, and attests student improvement to your teaching profile. On a tutoring marketplace, the platform owns your students, takes a big cut and keeps your reviews. Own it, and the tutor, the student list, the USDC payments and your teaching record stay with you.

What’s stopping you?

“What if the AI tutor gives a wrong answer?”

It will sometimes. Keep it grounded in your own materials, show students a 'ask the teacher' button, and review a sample of answers weekly. Tell students plainly it is an AI trained on your notes.

“I can't code.”

You upload your materials, set prices and answer escalations. The tutor, billing and badges come built.

“Will students pay per question?”

Some prefer it to monthly fees, especially before exams. Start with your existing students and a low price per question.

“Do students need crypto?”

They pay in USDC. Many will need help setting up a wallet the first time. Write a one page guide and expect to walk the first few through it.

“Is it really mine?”

Yes. Your materials, your wallet, your students. Deployed from your accounts.
