The true cost of AI writing tools, in dollars per 10,000 words, across six platforms — with the model tier, the quota ceiling and the overage rate all exposed.

What is inside (CSV + JSON):

• $/10k-words for every plan, computed on the word allowance each plan actually grants.

• Each vendor’s pricing-page source URL and the capture date.
