Free AI humanizers: how many words you really get
11 of the 20 humanizers we track offer something free. The biggest stated allowance is Hastewire's: free plan: 1,000 words a month, 300-word inputs, no credit card. Most free tiers are a few hundred words, enough to try one paragraph, not to process an essay. The table lists each one's cap, whether you need an account, and the cheapest paid plan if you outgrow it.

What "free" usually means here
Free tiers in this category are small on purpose: a one-off trial of a few hundred words, a monthly allowance, or a per-request cap that stops at a paragraph. Some need an account before you can paste anything. The numbers above are what each company states on its own site; we haven't yet checked whether every tool honours them.
What we're testing next
In November 2026 we'll run the same short texts through every free tier that doesn't need a card, and publish each output, the real word count it accepted, and how five free AI detectors scored it. Until then, this page only reports what the vendors say. How we test.
