A teacher who talks to you, listens, and explains.

Ask any NCERT question by voice. Your AI teacher finds the answer in your textbook, explains it clearly, and speaks it back. Like a private tutor - except it lives on your phone.

It actually feels like talking to a teacher.

Not a search bar. Not a chatbot. A conversation where you speak, follow up, and get clearer each time.

You talk, it listens

Hold the mic and ask your question naturally. Speech-to-text picks up English and Hindi. No typing required.

It talks back

Answers come as spoken audio with a lip-syncing avatar - not a wall of text. Feels like someone explaining things to you.

It remembers what you asked

Say "explain that simpler" or "give me an example" and it knows what "that" means. Real dialogue, not isolated queries.

Answers come from your textbook

Every response is grounded in the actual NCERT chapter. Semantic search finds the relevant paragraph before the AI speaks. No hallucinations.

It draws diagrams when it helps

Flowcharts, timelines, and process maps get generated inline when a concept benefits from being visualized.

It tests whether you understood

Earn Bronze, Silver, and Gold badges with AI-generated challenges - MCQs, application problems, and "find the flaw" exercises. Graded instantly.

Basic Q&A works offline too - a local AI model runs on your phone for when you don't have connectivity.

Question to understanding in seconds.

A pipeline running entirely on your phone.

Pick a chapter

Class, subject, chapter. The textbook PDF downloads and indexes itself with neural embeddings.

Ask anything

Speak or type. Vector search finds the most relevant textbook passages instantly.

Learn and prove

Get a clear explanation, then earn badges to solidify understanding. Bronze, Silver, Gold.

Prove you understood. Not just that you read it.

Three tiers of AI-generated challenges. New every time. No question bank.

Bronze

Speed Round

5 MCQs, 180 seconds. AI generates them from your chapter. Score 4/5 to earn it.

Silver

Apply It

3 real-world problems. Can you use the concept outside the textbook? AI evaluates your reasoning.

Gold

Find the Flaw

AI writes a deliberately wrong solution. You find the errors, explain why, and fix them.

Not a ChatGPT wrapper.

A ground-up ML pipeline built for phones that cost under 15,000 rupees.

On-device LLM

Gemma 3 (1B) via LiteRT-LM. Runs on your phone's GPU. No server needed.

Neural embeddings

MediaPipe Universal Sentence Encoder. Real semantic search, not keyword matching.

Cloud fallback

Gemini Flash via OpenRouter when online. Falls back to local silently when not.

Neural TTS

Gemini voices. Avatar lip-syncs via Rive bone animation in real-time.

Sentence-aware chunking

1200-char chunks, 3-sentence overlap. Never splits mid-sentence.

Resilient downloads

4-thread HTTP range requests with exponential backoff. Survives mobile network drops.

Built by students, for students.

We're Vishwak and Hamdan, Grade 9, Chrysalis High School, Yelahanka.

We noticed that AI tools either need constant internet, aren't aligned to NCERT, or cost more than our pocket money. So we built our own - from the on-device ML pipeline to the badge system.

"We wanted to prove that two 14-year-olds can ship real software - not a science fair poster, but something people actually use on their phones."
