How credits work
1 credit = HK$1. Top up on the Billing & Credits page with crypto (USDT, USDC or BTC) or PayPal. Crypto credits are added automatically once the payment is confirmed; PayPal top-ups are added after we confirm them by hand, then they are yours to spend on any report or refinement.
The free scan is our own instant analysis of writing patterns such as sentence variation and repeated transitions. It is an estimate generated by this website. The report is a separate paid order: you paste your text, and a person on our team runs it through a Turnitin screening workflow and records the result that screening returned.
