AI FORMULA CREDITS

PureLink AI Formula Credits

PureLink is free to use. These one-time purchases add AI formula drafts only; they are not subscriptions and do not make the core URL, manual formula, or card tools paid services.

What the product does

A signed-in customer can describe a mathematical expression in natural language and receive an editable LaTeX draft with an immediate visual preview. The result is never published automatically, may contain mistakes, and must be reviewed by the customer before use.

One-time plans

Small: 150 AI formula drafts — NT$150. Standard: 400 AI formula drafts — NT$300. Large: 1,000 AI formula drafts — NT$600. These are one-time purchases, not subscriptions.

Delivery and use

After payment is confirmed, credits are added to the PureLink account that started the purchase. Customers must be signed in before purchasing. The regular five free daily credits are used first. Purchased credits are only for the AI formula draft feature and are not shared between accounts.

Payment status

Available payment methods: Credit card / Apple Pay / TWQR and more.

Support

For purchase, delivery, or account questions, contact nasa3.14159@gmail.com. Include the email address used for your PureLink account and the order number, but never send a password, full card number, or Google credential.
