There are plenty of free worksheet sites. You are not paying for worksheets — you are paying to stop checking them, and to stop handing out the same sheet every other class already has.

One credit is one pack — not one worksheet. On Standard a pack can be up to 20 worksheets with an answer key for every sheet, so 50 credits a month covers up to 1000 worksheets. On Premium a pack goes to 40.
The free plan gets 5 credits a month, answer keys included, with up to 2 worksheets in a pack. Credits reset each month and unused ones do not roll over.
Every question and every answer is generated by code and checked against each other. That is a structural difference rather than a promise: an answer key that is computed cannot be wrong in the way a written or AI-generated one can. Mathematical errors are a recurring complaint about AI-produced practice material, and a wrong answer in front of a class is not a small cost.
A worksheet library is a finite set of files. Every teacher downloads the identical PDF, and so does every student who searches for it. Mathter generates fresh problems each time, across 70 skills from Kindergarten to Grade 12, so two classes doing the same topic never get the same page.
Worksheet packs are usually sold as finished files: you buy a set, you own that set, and when you need a different topic you buy another. Mathter is one subscription covering every grade and every skill. Standard works out to about 6 cents a worksheet if you make 4 packs a month — and every one of them is different.
Download a sample with no account at all — one page, no answer key. Create a free account and 14 days of Standard start straight away: no card, nothing to cancel. When the trial ends the account moves to the free plan on its own, and everything you have made stays where it is.
Billing questions — proration, changing plan, refunds — are answered in the FAQ and the refund policy.
