Plans differ only in allowances, requests a minute and site audit size, never in how text is judged or rewritten.
Billing questions.
For the API itself, read the developer docs.
When can I buy a plan?
Not yet. Every buy button says Coming soon until checkout opens. In the meantime, the tools work without an account, and a free account keeps your work.
What counts as a word?
Every word you send through the API or MCP to the X-Ray, the detector or Humanize, counted by the spaces between them.
What is a verified audit?
The second allowance on every plan. A certificate uses one, and so does a detector call in verified mode or a site audit run through MCP. Certificates and verified mode can also send that text to outside detectors.
What happens when I run out?
MCP tool calls stop with a 402 error that says how many words you have left. A top-up pack adds 250,000 words and 100 verified audits at once, or you can move up a plan.
Do unused words carry over?
No. Your count goes back to zero each time the monthly invoice is paid.
Do paid plans get a better detector?
No. The website, Pro, Growth and Agency all run the same detector and the same rewriting. Plans change how many words, verified audits and requests a minute you get, and how many pages a site audit reads.
Who handles payment?
Stripe. You will pay through Stripe Checkout and change or cancel a plan in Stripe’s billing portal.
