Voice Tutor: your personal AI teacher in real-time conversations
Natural AI conversations to review, debate, and dive deeper into your study topics. Available 24/7.
Imagine having a tutor that:

- You can interrupt when you have an urgent question
That's Voice Tutor.
What is Voice Tutor
Voice Tutor is a real-time conversation with an AI specialized in your study material. It's not a chatbot you type to and read. It's a natural voice conversation, like talking to a teacher.
| Traditional AI Chat | Voice Tutor |
|---|---|
| Type your question | Just talk naturally |
| Read long text responses | Listen to clear explanations |
| Scroll through text | Visual aurora feedback |
| No interruptions | Barge-in support |
| Generic AI | Specialized in YOUR content |
How it works
| Step | Action |
|---|---|
| 1 | Open your study node (e.g., "Solar System") |
| 2 | Click green "Tutor" button in top bar |
| 3 | AI reads your content & prepares |
| 4 | Start talking - AI listens |
| 5 | Fluid conversation with interruptions |
Unique features
| Feature | What it does | Why it matters |
|---|---|---|
| 🎤 Barge-in | Interrupt AI anytime | Natural conversation flow |
| 🔥 Rensei Integration | Updates mastery scores | Measures real understanding |
| 🎨 Immersive UI | Full-screen aurora | Total focus experience |
| ⚡ Ultra-low latency | < 500ms response | Feels like talking to a human |
🎤 Barge-in (smart interruption)
If the AI is explaining something and you have a question, just start talking. The AI stops immediately and listens to you. That's how a real conversation works.
🔥 Rensei Integration
If you have Rensei activated in the node, Voice Tutor:
| Before session | During session | After session |
|---|---|---|
| Loads weak concepts | Focuses on gaps | Updates mastery scores |
| Reviews your progress | Adapts difficulty | Identifies improvements |
🎨 Immersive experience
The interface transforms into a full-screen overlay with a visual aurora that reacts to your voice and the tutor's. It's an experience designed for total focus.
⚡ Ultra-low latency
| Technology | Latency | Experience |
|---|---|---|
| Traditional TTS/STT pipeline | 2-4 seconds | Robotic, frustrating |
| Gemini 2.5 Flash Live | < 500ms | Natural, fluid |
Use cases
1. Pre-exam review
You: "Explain the main events of the French Revolution"
AI: "Sure, let's start with the storming of the Bastille in 1789..."
You: (interrupts) "Wait, why is that date so important?"
AI: "Excellent question. The Bastille symbolized..."
2. Debate to deepen
You: "Why is the Big Bang the accepted theory and not others?"
AI: "There are several key pieces of evidence: the expansion of the universe observed by Hubble..."
You: "But what about steady-state theory?"
AI: "Good observation. That theory was popular until..."
3. Presentation preparation
You: "I'm going to present about photosynthesis, simulate being my audience"
AI: "Perfect, go ahead. I'm listening as if I were a classmate"
You: (explains the topic)
AI: "Excellent explanation, but you could clarify more the difference between light and dark phases..."
Transparent limitations
Voice Tutor only knows your node. If your node is about "Solar System" and you ask about "Trading", it will redirect you to the node's topic.
This is intentional: we want it to be a focused tutor, not a general chatbot.
Cost and availability
Voice Tutor is included in the STUDENT plan ($20/month) with 1.5 hours per week. That's enough for:
| Usage Pattern | Sessions | Best for |
|---|---|---|
| Deep dive | 3 × 30 min | Complex topics |
| Thorough review | 2 × 45 min | Exam prep |
| Intensive prep | 1 × 90 min | Final cram |
Cost comparison:
| Tutoring Option | Monthly Cost | Hours/month | Cost per hour |
|---|---|---|---|
| Human tutor | $60-120 | 4-6 hours | $15-30/hour |
| Voice Tutor | $20 | 6 hours | $3.33/hour |
Why limited? Because we want it to be a complement, not a substitute for your active study. Voice Tutor enhances what you already do, it doesn't replace it.
The future of studying
10 years ago we studied with books and highlighters.
5 years ago we added YouTube videos and Notion.
Today, we talk to an AI that understands our material and helps us master it.
The future of studying is already here.
