Before you pay
- The $12 price is billed yearly ($144 up front); month to month, Pro costs $30, or $60 a quarter.
- Superhuman's own Pro suite plan lists Grammarly paragraph rewrites, AI-text and plagiarism checks plus its Docs and Go apps for $15 billed monthly, half Grammarly Pro's monthly price, but its page gives no prompt count.
- No refunds: the terms make payments non-refundable, with no credit for unused time, as far as the law allows.
- Free, Premium and Pro accounts bought on Grammarly's website let it train its models on your writing by default; switch off Product Improvement and Training in your settings (on a team plan, only an admin can).
