Why consider a Grubby AI alternative?
Two numbers and a feature. The numbers: $4.99 buys 25,000 humanized words here versus 7,500 to 30,000 words for similar money on Grubby's published plans, and their lowest advertised prices require annual billing. The feature: unlimited free detection on every page, so every rewrite from any tool can be verified before you trust it.
Price per 100,000 Words, Side by Side
Word caps make humanizer pricing hard to compare, so normalize everything to the cost of 100,000 humanized words on monthly billing:
| Tool | Plan | Price | Words / month | Cost per 100K words |
|---|---|---|---|---|
| Humanized by AI | Starter | $4.99/mo | 25,000 | $19.96 |
| Humanized by AI | Pro | $19.99/mo | 150,000 | $13.33 |
| Grubby AI | Essential | ~$7.99/mo | 7,500 | ~$107 |
| Grubby AI | Pro | ~$9.99/mo | 30,000 | ~$33 |
Monthly billing, from each tool's published pricing as of July 2026. Plans change; always confirm current numbers on the vendor's site.
Grubby's free tier covers 300 words a month; ours covers zero humanized words but unlimited detection, because checking is the step you repeat constantly. Their advertised prices below these numbers are annual-billing equivalents, so read the fine print before comparing.

The Twenty-Minute Test
Skip the review roundups. Take one draft that actually matters to you, humanize it in both tools, then paste both outputs into the free detector here. Compare the scores, then read both versions aloud and ask which one you'd submit under your own name. The whole experiment is free, and it answers the only question that matters: which rewrite is better on your writing, and at what price per word.
