Answers in plain language

Every new student account starts on a 42-day Advanced trial (no card required): full AI Study Coach, AI Mock Exams, the Exam Readiness score (A/L), and every Advanced feature unlocked. On day 43 the account converts to the Free plan automatically. There is no surprise charge — you only pay if you actively subscribe.

Study dashboard, Curriculum Tree, Short Notes, past-paper practice, placement assessment, and 5 AI Study Coach questions a day. The trial's paid features (AI Mock Exams, the full Exam Readiness score for A/L, the larger AI coach allowance) lock again until you choose Mastery.

Students choose Free or Mastery. Mastery is listed at LKR 7,500/month for Pre-O/L and O/L, and LKR 15,000/month for A/L. These are list prices; the Pricing page shows any current offer. Multi-child family discounts apply automatically (10% off 2nd child, 15% off 3rd, 20% off 4th+), down to a minimum charge of LKR 1,500/month per child. See the full breakdown on the Pricing page.

Yes. Cancel from your dashboard at any time. Your plan stays active until the end of the billing period, then reverts to Free. No cancellation fees, no lock-in contracts.

You ask a question; the coach searches our syllabus-aligned Knowledge Packs and returns a grounded answer with a worked example. If the coach isn’t confident, it says so and points to the source material — no fabricated formulas.

The interface is fully trilingual (English, Sinhala, Tamil). The AI Study Coach answers in any of the three languages. Lessons are in English for every subject, and in Sinhala for the O/L subjects and the A/L Science subjects, where some units are still being added. Tamil lessons are still being added and do not yet cover O/L Mathematics or Science.

Seven O/L and A/L subject hubs: O/L Mathematics, Science and English, and A/L Physics, Chemistry, Biology and Combined Mathematics. The Own Your Future track adds Digital Literacy, AI Aptitude, Employability, Financial Literacy, and Entrepreneurship.
