Pricing
Start free. Go deep when it counts.
Every concept guide, quiz, and problem is built to FAANG standard — not a 101 tutorial. One platform covering DSA, System Design, ML, ML System Design, and GenAI. The free tier lets you explore. Pro is for candidates who want to walk in knowing more than the interviewer expects.

Auto uses your device timezone (UTC). If you are in the US but see INR, choose USD above — common when the OS timezone is still IST or a VPN does not change the timezone.

Common questions
- What is Pro 6 Month vs Yearly?
- 6 Month is a single six-month access window at a lower upfront cost—ideal for one focused prep season. Yearly is the best per-month value and matches a full interview cycle with room to revisit material. Both unlock the same Pro content; the difference is how long your access stays active before renewal or upgrade.
- What's the difference between Yearly and Forever?
- Yearly renews annually and you can cancel anytime — good if you're prepping for a specific cycle. Forever is a one-time payment: you own access permanently, including all future content. Interviews come around again; Forever means you never pay twice.
- Which content is free?
- Every track includes free foundational guides so you can evaluate quality before upgrading. Advanced deep-dives, most case-study heavy content, full quiz access, and complete practice coverage are part of Pro. Exact free counts vary by track and evolve as new topics are published.
- Do Indian users pay GST?
- Yes — Indian customers pay 18% GST on digital services. The INR prices shown are already inclusive of GST, so what you see is what you pay. International users (outside India) pay USD with no Indian GST.
- Can I switch from Yearly to Forever?
- Yes — contact support and we'll credit your remaining subscription time toward the Forever plan price.
