1 · Problem details
2 · Transactions
Paste the transactions (one per line; a date or serial at the start of each line is recognised) or import a PDF. Then split into transactions and tidy them up on the right.
हिन्दी (optional)
Paste the same transactions in Hindi, one per line in the same order (serial numbers at the start are ignored). They are matched to the English rows by position; you can also type or correct the Hindi directly in the rows on the right.
3 · Review & edit
No transactions yet.
4 · Save & share
Students either import the .json file from the Home screen, or open the share link (the whole problem travels inside the link, so no server is involved). Problem files can also be published in the site's course library.
