Frequently Asked Questions

What is the Chalcack AI study app?

Chalcack is a 24/7 AI-powered study companion, math solver, and homework helper app. Simply snap a photo of any tough problem (Math, Physics, Chem, English grammar, etc.), and Chalcack will automatically break down the solutions into clear, logical, step-by-step instructions.

How is Chalcack different from standard textbook answer keys?

Chalcack does not just hand you static answers. It features a 1:1 interactive AI tutor chat that handles unlimited follow-up questions. You can ask details like 'Wait, why does this step work?' or 'Explain this concept simpler' until the material finally clicks. It bridges the gap between searching answers and true concept mastery.

What academic subjects and test prep does Chalcack cover?

We cover comprehensive school subjects: Mathematics (Algebra, Function, Geometry, Trigonometry, Calculus, Matrix), Science (Physics, Chemistry, Biology), Language Arts (Reading, Grammar, Literature), and History. It is also an excellent tool for test prep such as SAT, ACT, AP, IB, and language proficiency exams.

How do I manage my study vault and review notes?

Chalcack automatically saves all your scanned problems and explanation history into a secure personal study vault. You can easily access past questions to build review libraries, bridging knowledge gaps as customized wrong-answer notes before major exams.

How much is Chalcack PRO, and what payment methods are supported?

Core scanner functions are free. For unlimited AI chat, follow-ups, and deep concept masteries, you can upgrade to Chalcack PRO for $9.99/month (auto-renewal). We support secure Kakao Pay checkouts and App Store billing, and you can cancel or manage subscriptions anytime directly in the app.
