Credits are the unit every plan and pack is denominated in. A check spends credits by length; everything else in the report (fixes, citations, downloads) is included.
What a check costs
About 150 credits per 250 words, counted in started 250-word pages: a 300-word draft costs two pages, and a check is never billed for fewer than one page. Checking the same text again costs again, so make your edits and then choose Check again once.
Where credits come from
- Plan allowance. Pro Monthly and Pro Annual include 36,000 credits every month (about 60,000 words of checking); Pro Weekly includes 9,000 every week (about 15,000 words). The allowance refills on your billing date and unused credits do not roll over.
- Top-up packs. Bought once, never expire, and are spent only after the period's allowance is used. See the article on plans, packs and prices.
- The free account completes your first full document without credits.
Seeing your balance
Account → Usage shows the period's allowance, what is left, and the pack balance separately. The dashboard shows the same figure.
Running out
When the allowance is gone, a check tells you before it runs and offers a pack or a plan change. Reports you already made stay open and downloadable.
