The difference

Board prep,
before and after.

Without StudyOS
  • Forgetting which chapters you've actually covered
  • Realising SST or English is far behind — 3 weeks before exams
  • Revising the same chapters you enjoy, skipping the hard ones
  • Walking into the exam hall not knowing what you forgot
With StudyOS
  • Every subject, every chapter — tracked and visible at a glance
  • AI flags what's falling behind before it becomes a crisis
  • Spaced reminders ensure every chapter gets revisited — not just your favourites
  • You know your exact readiness — confident, not anxious, on exam day

The real problem with board prep

Most students juggle five subjects across 60+ chapters, forget what they revised last week, and only realise how far behind they are when the exam is two weeks away. StudyOS closes that gap — one workspace to track everything, get reminded on time, and never blank during boards.

What's inside

Everything you need.
Nothing you don't.

Built specifically for CBSE — not a generic to-do app in a dark theme.

Full NCERT chapter list pre-loaded for Class 9–12. Mark chapters as done, in-progress, or pending — always know exactly where you stand across every subject.

Why I built this

A note from
the founder.

The Builder
Creator of StudyOS · Built this for CBSE students, by a CBSE student

I built StudyOS because I kept watching the same thing happen every year — students who worked hard all year still panicking in the last month because they had no real picture of where they stood. Not because they were lazy. Because the tools were wrong for them.

Notion is too blank. Google Sheets breaks when you need it most. Every "study app" out there was built for someone else's curriculum, someone else's exam pattern. None of them knew what NCERT chapters existed, let alone which ones needed revision first.

So I built one specifically for CBSE — Class 9 through 12 — with the full chapter list pre-loaded, spaced repetition built in, and an AI coach that actually understands the syllabus. It's completely free, and it stays that way. No ads, no paywalls, no premium tier. Just the tool I needed when I was preparing for boards.

Questions

Frequently asked

Is StudyOS actually free?
Yes, completely. No credit card, no trial period, no premium tier hiding useful features. Everything on this page is free and stays that way.
Which classes and subjects does StudyOS support?
StudyOS supports CBSE Class 9, 10, 11, and 12. For Classes 9 and 10, NCERT chapter lists for all five subjects are pre-loaded. Class 11/12 streams (PCM, PCB, Commerce) are also supported with the relevant syllabus.
Does my data sync between phone and laptop?
Yes. StudyOS is cloud-synced via Supabase — your chapter progress, reminders, and streak stay in sync across every device you're signed in to. Open on your phone after class, pick up on your laptop at home.
How does the AI Study Coach work?
The AI coach knows which chapters you're tracking and where you're behind. Ask it to explain a concept, give practice questions, or build a study plan — it gives you a direct answer, not a search result. Available any time from the dashboard.
What is spaced repetition?
Spaced repetition is a technique backed by decades of memory science — you review material at increasing intervals so it moves into long-term memory. StudyOS schedules revision reminders automatically based on when you last studied each chapter.
Is my data private and secure?
Your data is stored in Supabase (encrypted at rest and in transit) and is never sold or shared. You can delete your account and all data at any time. See our Privacy Policy for the full details.
Ready? It's free.
