The darker the ink, the better you remember it:
Inside the book

University, medical and engineering. The HSC + admission combo is for second-year HSC students.
What's inside. The SSC Khata already holds 28,000+ MCQs and 23,000+ flashcards across 195 chapters. HSC's 162 chapters are being written now. The MCQs are built from past board questions, so what you remember is what the exam asks.
Free with it. Every khata bought at the waitlist price comes with a month of the "Explain it" AI free, a ৳200 value. Stuck on a chapter? Ask right inside it. It stops by itself when the month ends, and nothing is charged.
Why now. To get these prices, sign up before launch. Then you have one month from launch day to buy. People who arrive after launch pay more: the first 200 get half price, and then it climbs step by step to full price.
The first chapter of every subject is free. Single subjects can be bought at the prices in the table; the discount is on the khatas only. At launch it's science group only. Humanities and Business Studies, sorry: your khatas come later, you'll hear first, and you'll get 60% off then too. The "Explain it" AI is separate, monthly and optional. bKash, Nagad, cards.
Questions
What is Chirkut?
Chirkut is a study app: interactive notes, flashcards and quizzes for every chapter of SSC, HSC and admission tests, in one place. Whatever you're about to forget, it brings back just before you do.
How does Chirkut help me remember?
Spaced repetition. It's a proven, scientific way of remembering, backed by more than a century of research. For every card, the app tracks how well you hold it and brings it back right before you'd forget. So things stick without reading them over and over. Study less, retain more. Read more →
Which classes?
SSC, HSC and university admission tests first, for the science group. Humanities and Business Studies come later, then Classes 6 to 9.
How much does it cost?
The first chapter of every subject is free. The SSC Full Khata is ৳2,499, or ৳999 on the waitlist. The HSC Full Khata is ৳3,499, or ৳1,399 on the waitlist. Any 4 admission subjects are ৳999, or ৳399 on the waitlist. A whole khata costs less than a month of tuition, and once bought it's yours forever. Khatas bought at the waitlist price come with a free month of "Explain it". The AI explainer inside each chapter is a separate monthly subscription: take it if you want it, and everything else works without it. bKash, Nagad or card.
Is the AI separate?
Yes. The explainer is a monthly subscription on top of the subject price. It never switches itself on, can be cancelled in any month, and cancelling leaves your subjects exactly as they were. Without it, notes, cards, quizzes and the memory map all work fully.
Does it work offline?
Yes. Bought subjects are saved on your phone. Notes, cards and quizzes all work without internet. Only asking the AI a question needs a connection.
When is it coming?
January 2027, on Android and iOS together. Join the waitlist and the prices and next steps come to your inbox right away. You then have one month from launch day to buy at the waitlist price.
