Undetectable AI is one of the best known AI humanizers, so it is the tool most people compare us with. This page sticks to what you can check on both pricing pages: price per word, trial terms, guarantees and features. Where Undetectable AI is the better fit, we say so. The fastest test is still to run the same paragraph through both.

Why PureWrite
At the same $9.99 monthly price, PureWrite Pro includes 16,000 words a month, while Undetectable AI's entry plan lists 10,000. On annual billing, Pro is $4.99 a month for 16,000 words; their 10,000 word plan is $5.00 a month billed yearly.
PureWrite takes up to 2,000 words per run on Pro, 5,000 on Ultra and 10,000 on Unlimited. Paste the whole essay or report once instead of splitting it into chunks and stitching the results back together.
Paid plans include a custom writing style: give PureWrite a sample of your own writing and results follow your voice. Output works in 50 languages, and every result comes with a built-in AI check.
The free trial needs no credit card. If you subscribe and it stops being useful, you cancel in 2 clicks from your dashboard. Your text is never used to train AI models.
Comparisons are useful, output is decisive. Paste your draft into the PureWrite editor, humanize it, and check the built-in AI detection score. No signup needed to see a preview.
