The Story

Why is everything free?

wondermayank has been building free educational and utility tools for students since 2018 — across ThunderStudy, ThunderAI, and 800+ tools and counting. Turning 8 years old felt like the right moment to remove every remaining limit on the AI side of ThunderStudy: the ₹1,500 price is gone, dropped to ₹0 for every student, with performance held at exactly the same level as before.

Free doesn't mean held back

The only constant across every Tiny AI model on ThunderStudy AI is a fair daily and weekly mock test cap — nothing else changed. Question quality, exam-pattern accuracy, and generation speed are all performance as high as pre-level.
