FAQ
Quick Answers
Are all these AI tools free to use?
Yes — every tool listed here is free to use, the same way the rest of ThunderStudy and Wondermayank are. Some may have optional premium features down the line.
What's the difference between Study AI and Personal AI?
Study AI tools live under ThunderStudy and are built specifically for exam prep — CUET, SSC, Banking, UPSC. Personal AI tools live under Wondermayank and are built for everyday conversation and self-care, with no exam context.
Who builds and maintains these tools?
All six are built and maintained solo by Thunder (wondermayank), as part of a wider suite of 80+ free web projects spanning study tools, utilities, and creative sites.
Do I need to sign up to use them?
Most tools work without an account. A few ThunderStudy tools may ask for a quick Google sign-in to sync progress across devices.
