About this site
VedicMath AI collects a coherent set of mental-maths techniques and turns them into a training loop: read the rule, watch the derivation, drill it, test it under a clock.
Where the methods come from
The technique set follows 《Mental Math: Tricks To Become A Human Calculator》 by Abhishek V.R. (Ofpad), together with the classical Vedic arithmetic lineage it draws on: digital roots, left-to-right operations, base-and-complement work, and flagpole division.
Physics and chemistry speed tricks follow the same idea in a different domain: check the dimension, substitute a special value, sketch the graph, keep ratios intact, and convert everything to moles once.
How the site is built
- Plain HTML, CSS and JavaScript — no framework, no build step
- Two parallel language trees (
/for 中文,/en/for English) with a shared switch - All arithmetic runs locally in your browser
- Account registration posts to Supabase with row level security
Demo notice & pricing
This is a demonstration deployment. The paid plans, prices and discounts shown on the pricing page are example copy: there is no payment provider, no card form, no charge and no refund process. Selecting a paid plan only records your interest so we can follow up by email.
Your data and privacy
- Practice data — questions, timers and results are computed in the browser; nothing is uploaded while you drill.
- Preferences — theme, language and currency are stored in your browser's localStorage.
- Account — if you register, your name, email, optional mobile number, chosen plan and language are stored in our Supabase project (
wqatcoytxlptmpvbfogw). - Passwords — hashed in the browser (SHA-256 with a salt) before transmission; the plain text never leaves your device and only the hash is stored.
- Access control — row level security allows anonymous clients to insert a registration but never to read the table; login verification runs through a security-definer function that never returns the hash.
- No tracking — no analytics, no advertising, no third-party scripts.
Feedback
Found a wrong derivation or an awkward drill? Tell us the lesson and the step — that is the fastest way to fix it.
Teaching with it
Teachers are welcome to use the lessons in class. Each technique fits inside a single period, with the practice centre as homework.
