How it works

Dr. Curiosity, a friendly AI mentor, guides students through every step of a real science fair project — you just share one class code. Here's everything, start to finish.

The big picture: School → Rooms → Students

1. A school or workspace

Holds your rooms and the people who manage them. Buying alone? A personal workspace is created for you automatically — no setup at all.

2. Rooms = class codes

One room is one class code shared by a group of students, with its own seat count and its own balance of AI credits.

3. Students just enter the code

No accounts, no emails, no sign-ups — ever. An optional made-up nickname + 4-digit PIN lets a student pick their project back up from any device.

What students experience

A mentor, not an answer machine. Dr. Curiosity asks guiding questions, runs quizzes, and suggests activities — the student does the science.

The real scientific method, step by step. From question to conclusion, explained at the right level for elementary, middle, and high school.

Print-ready results. Worksheets for every step and a tri-fold display board template, ready for fair day.

Work that follows them. With a nickname + PIN, students continue at school, at home, or on the library computer. Forgot the PIN? The teacher can reset it.

Setup for teachers & parents

1Create a free account. Sign in with an email link or Google. No credit card, no trial clock — the account itself costs nothing.
2Buy a plan sized to your group. From 1 student up to 500. Pick a preset class plan or type a custom size — a parent buying for one kid is just as welcome as a school buying for a hundred. Plans are prepaid subscriptions: 6 months by default, or up to 3 years at a discount, and nothing ever auto-renews.
3Load AI credits. Credits pay for Dr. Curiosity's chats, metered per message. A suggested amount is pre-filled at checkout, and you can start smaller and top up anytime.
4Share your class code. That's the whole student rollout: write the code on the board or send it home. Students enter it and start working immediately.
5Watch it happen. Your dashboard shows who's joined, messages sent, and credits spent — per student. Pause a room, lock joins, add seats, or top up credits whenever you like.

Setting up a whole school?

Create a named school on the dashboard first, then invite colleagues by email — they get access the moment they sign in. Owners manage everything, Teachers buy plans and run their classes, and Viewers see stats only. If someone leaves the school, its rooms, codes, and credits carry on without them.

What it costs

Two parts — a prepaid subscription for the seats, and prepaid credits for the AI chats. Nothing auto-renews and your card is never stored:

1. Subscription — what you pay us. One class code and its seats, active for the term you choose. When it ends, renew from the dashboard — students, work, and credits are exactly where you left them.

2. AI credits — what the chats cost. Prepaid and metered per message. About $3.12covers one student's whole project.

Class size	Per 6 months	Per student	Savings
Any custom size (1–500)	30¢ per student ($1 minimum)	$0.30	—
20 students	$5.00	$0.25	Save 17%
40 students	$9.00	$0.22	Save 25%
100 students	$20.00	$0.20	Save 33%

Commit longer, pay less

Every plan is prepaid for a term of your choice: 6 months, 1 year (10% off), 2 years (20% off), or 3 years (30% off). An expired room deletes nothing — renewing picks the class back up with the same code, students, and credits, and renewing early just adds time on top.

Credits never expire, and whatever students don't use stays in the room.
When credits run low you top up in dollars — never a surprise charge; chats simply pause until you do.
Outgrew your room? Add seats anytime and only pay the difference for the time your room has left.
Payments are handled by Stripe; card details never touch our servers.

Change your mind? Refunds are self-serve

Plan, renewal, and seat fees are fully refundable within 5 days. Unused AI credits are refundable within 30 days of buying them — the dashboard shows the exact refundable amount next to every purchase, and one click sends the money back to your card. Read the full refund policy.

Built for classrooms, built for privacy

Students never hand over personal information

No accounts, no email addresses, no passwords, no real names — just the class code and, optionally, a made-up nickname with a PIN. Teachers stay in control the whole way: pause a room, lock joins so no one new can enter, remove a student, or reset a PIN. Daily message limits and per-student spending caps are built in, so one enthusiastic student can never drain the class budget.
