Learning that
makes sense
We're building an AI-powered platform that helps students understand deeply, think clearly, and build genuine confidence — not just pass exams.
What is Teengro?
Teengro is a free AI tutor purpose-built for Indian school students in Classes 8 to 12, supporting ICSE, CBSE, NCERT, and AP (Andhra Pradesh) boards. It gives clear, step-by-step explanations across every major school subject, generates AI flashcards, creates educational diagrams, accepts voice and image input, and replies in 9 Indian languages.
Unlike a generic chatbot, Teengro is grounded in the actual NCERT textbook corpus and stays focused on a student's exact syllabus — never going off-topic, never giving shortcuts, never pretending to be something it isn't.
Our Mission
At Teengro, we believe that every student is capable of understanding — they just need explanations that are clear, patient, and adapted to how they think.
Too many students lose confidence not because they lack ability, but because learning feels rushed, confusing, or impersonal. We're changing that.
Our mission is simple: help students learn with clarity, build confidence naturally, and develop the thinking skills that matter long after school ends.
Why Teengro?
Most students don't struggle because they're weak — they struggle because explanations are rushed, confusing, or overloaded.
Teengro fixes that. It breaks concepts down step-by-step, adapts to your level, and helps you think clearly instead of memorising blindly.
- Step-by-step explanations, not instant answers
- Designed for teens — simple language, clear logic
- Generate visual diagrams to understand concepts better
- Chat history so you never lose a good explanation
- Minimal UI that keeps distractions away
- Learn at your own pace, without pressure
- Streak freeze to protect your progress on missed days
- Built-in flashcards with AI generation and XP rewards for studying
- XP and level system that grows as you learn
Imagine if your NCERT textbook could speak.
That's what Teengro is. Most AI tools guess answers from whatever they scraped online. Teengro doesn't guess — it looks things up directly from your actual NCERT textbooks before answering, then explains them in your own words.
We built this using a technique called RAG (Retrieval-Augmented Generation). In plain English: when you ask a question, Teengro first searches the real textbook for the most relevant pages, then uses those pages to write its answer. The answer comes from the book — not from the AI's memory.

The result? Textbook-accurate answers, every time. Instead of hoping the AI got it right, you can trust that what Teengro tells you actually comes from the book you'd be tested on.
See It In Action
A clean interface designed for focused learning — no clutter, no distractions.
Hello there! I would be happy to help you understand Photosynthesis for your ICSE exams.
Photosynthesis is defined as the process by which living plant cells containing chlorophyll produce food substances (glucose) from carbon dioxide and water by using light energy. Oxygen is released as a byproduct.
The process takes place in two main phases:
1. Light-dependent phase (Light Reaction): Occurs in the grana of the chloroplasts...
equation is always fully balanced as shown above to secure full marks.
Key requirements for the process:
- 1. Carbon dioxide
- 2. Water
- 3. Chlorophyll
- 4. Sunlight
Remember, photosynthesis is a constructive or anabolic process that converts light energy into chemical energy stored in the bonds of glucose. Keep up the good work with your studies!

Built by a Student, For Students
Teengro was founded by Bandaru Sushanth Kumar, a student who understands firsthand the challenges of learning in today's education system.
This isn't a product built by people guessing what students need — it's built by someone living the experience. Every design decision, every feature, every word is shaped by a deep understanding of what actually helps students learn.
We believe age shouldn't limit ambition, and students are capable of far more than they're told.
