Question 1

Is Guru Sishya really free? What's the catch?

Accepted Answer

Yes - 141 topics, 1988 quiz questions with answers, 693 full sessions, flashcards, and all progress tracking are free forever. No credit card, no email required. We offer a Pro tier (Rs 149/month or Rs 1199/year) for AI-powered features like the Guru Mode and custom topic generation, but the core prep content will always be free.

Question 2

Do I need an API key or AI subscription?

Accepted Answer

No. All lesson content, quiz questions, quick saar notes, STAR behavioral answers, and the learning ladder are pre-generated and bundled into the app. They work entirely offline in your browser. Only the optional AI features (Guru Mode, custom topics) require a Pro plan.

Question 3

What topics does Guru Sishya cover?

Accepted Answer

138 topics across four domains: System Design Fundamentals (load balancing, caching, databases, message queues, CDNs), System Design Case Studies (Twitter, YouTube, Uber, etc.), Data Structures and Algorithms (arrays, trees, dynamic programming, graphs), and Core CS (operating systems, networking, databases, compilers). More topics are added regularly.

Question 4

How is Guru Sishya different from LeetCode, AlgoExpert, or NeetCode?

Accepted Answer

Guru Sishya is the only platform that combines all of this in one place for free: 1933 questions with full answers (not just hints), 58 STAR behavioral answers, 32 system design topics, spaced repetition flashcards, offline access, and Bloom's taxonomy adaptive quizzes. Competitors charge Rs 991-Rs 2917/month and still lack behavioral prep and offline support.

Question 5

Does Guru Sishya cover behavioral interviews?

Accepted Answer

Yes. Guru Sishya includes 58 pre-written STAR behavioral answers for the most common interview questions at Google, Amazon, Microsoft, Meta, Apple, and Netflix. These cover leadership, conflict resolution, ownership, impact, and more.

Question 6

Will my progress be saved?

Accepted Answer

Yes. All progress is saved locally in your browser using IndexedDB - no account required. Your data is private and works offline. If you clear your browser data, your progress will reset.

Question 7

What is the Pro plan and what does it include?

Accepted Answer

Pro (Rs 149/month or Rs 1199/year) unlocks AI-powered features: the Guru Mode interactive chat for deep understanding, custom topic generation, priority support, and a certificate of completion. All core prep content remains free forever.
