The short answer
GRAMMARLY charges are Grammarly Premium — and the surprise is usually the billing cycle, not the product: annual and quarterly plans bill as one lump sum (about $144/year), not monthly.
Why it shows up like this
Grammarly defaults many signups to annual billing because the monthly equivalent looks cheap at checkout. A year later, the lump renewal arrives with no monthly rhythm to warn you.

Quick questions
Why is the charge $144 instead of $12?
Annual billing — the advertised monthly rate is the annual price divided by twelve, charged once. It's the most complained-about part of Grammarly's billing.
