Hey! What subject shall we tackle today? 😊
I'm stuck on quadratic equations…
Let's start from what you already know. Try this: x² = 9
x = 3?
Almost! There's another answer. Think negative numbers… 🤔

How It Works

1

You Choose a Token Package

1 token = 1 mastered topic. Starting at Rp49K for 10 tokens, backed by our guarantee — topic not finished, token not consumed.

→
2

Your Child Learns on WhatsApp

Riku guides them through one topic until mastery — using spaced repetition, retrieval practice, and scaffolding.

→
3

You See the Proof

A token is only consumed when the Progress Tracker marks a topic complete. Every completed topic visible in your parent dashboard.

Why This Method Works

Same pedagogical engine as elite private tutors — delivered through WhatsApp.

🔄

Spaced Repetition

Every concept revisited at the optimal interval — right before your child starts to forget. How the brain builds permanent memory.

❓

Retrieval Practice

Riku doesn't give answers. It asks questions — forcing your child to recall from memory. The single most effective learning technique known to science.

🪜

Scaffolding

Building from what's known, step by step to what's new. No frustrating leaps. No giving up halfway.

🎯

One Topic, Until Mastered

No rushing to the next topic until this one is truly understood. Depth over speed. This is why we offer a guarantee.

Proof, Not Promises

The parent dashboard shows exactly what your child has learned and mastered. Not estimates. Not "they seem to be doing fine."

Token Packages

1 token = 1 mastered topic = 1 payment. Didn't finish the topic? Token stays. No risk.

🧠 Why no free trial?

Free trials attract tire-kickers, not committed parents. By paying upfront, every student on Riku is a student whose parent is serious about their education. And you're protected: topic not mastered, full refund. No questions asked.

A Guarantee That Actually Means Something

We don't get paid until your child actually understands the material.

🎯

Pay Per Mastered Topic

A token is consumed only when the Progress Tracker marks a topic complete. As long as your child is still learning, the token stays.

🛡️

Failed Topic = Money Back

If after multiple sessions your child still hasn't mastered a topic, we refund that token. Not store credit — your money back.

📊

You See Every Result

Real-time dashboard: which topics are done, in progress, or untouched. No more "my child says they studied."

This isn't a marketing claim. It's the logical outcome of our method:
if our system doesn't work, we don't deserve your money.

Frequently Asked Questions

How is Riku different from a regular AI chatbot?

A chatbot just answers questions. Riku is a learning system: it follows a curriculum, applies spaced repetition, prompts retrieval, builds from easy to hard (scaffolding), and tracks mastery of every topic. AI is the engine — pedagogy is the brain.

How does the guarantee work?

1 token is consumed only when a topic is marked COMPLETE in the Progress Tracker. If after several sessions your child hasn't mastered the topic, the token is refunded to your balance. Contact us via WhatsApp, processed within 24 hours.

What subjects are available?

All subjects for children ages 7+: Math, Physics, Chemistry, Biology, English, Indonesian, History, Geography, Economics, and more. Elementary through high school level. Plus custom subjects via PDF upload.

Can my child switch between subjects?

Of course! Tokens work across ALL subjects and custom materials. Math today, English tomorrow — all from the same balance.
