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 and optionally provide one PNG or JPEG reference image, then receive an editable LaTeX draft with an immediate preview. The description and image are sent to the current AI provider only when generation is requested; PureLink does not retain them or a separate AI-draft history. If the customer chooses Create, the selected formula is stored as ordinary shared content. Provider retention terms apply. The draft is not published automatically, may be wrong, and must be reviewed before use.
One-time plans
Paid AI credit purchases are currently unavailable during the public beta. Five free AI formula generations remain available daily.
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
No payment rail is enabled in this deployment. No payment is accepted until it is enabled.
