USD prices for the cheapest paid plan, from each vendor's pricing page in November 2026. "—" means the vendor doesn't publish that figure. Vendors change prices often, so check before you buy.
Every tool is scored on the same four criteria, so the ratings can be compared directly.
Does the rewrite read naturally, keep the original meaning and avoid the stiff, "spun" phrasing that gives AI text away?
The price per word on the cheapest plan, the yearly discount, and whether monthly limits fit real workloads.
Can you try it without paying? We favour real free allowances over $1 trials and tiny word caps.

GPTHuman AI is our #1 AI humanizer for November 2026. It combines a dedicated humanizer, a built-in AI detector, 50+ languages and a "bypass all AI detectors" guarantee, starting at $8.25/month billed yearly. StealthWriter has the most generous free tier (10 runs a day), Undetectable AI is the best all-in-one suite, and QuillBot AI Humanizer is the best free option from a major brand.
An AI humanizer is a tool that rewrites AI-generated text from ChatGPT, Claude, Gemini and similar models so it reads more like natural human writing. It changes sentence rhythm, word choice and structure, which reduces the patterns AI detectors look for.
13 of the 19 tools we list have a free plan or trial. StealthWriter has the most generous free tier, with 10 humanizations a day at up to 1,000 words each. Humanize AI Pro is completely free with no stated limits. QuillBot and Grammarly both offer free basic humanizers.
Paid plans start from $5/month. Undetectable AI and Twixify cost $5/month on yearly billing, and AIHumanize.io costs $6/month.
16 of the 19 tools include a built-in AI detector or checker, so you can check your text before and after humanizing it. Undetectable AI and Netus AI include unlimited AI detection on paid plans.
We rank tools on output quality, value for money (price per word on the cheapest plan), how useful the free tier is, and features such as built-in detectors, languages, input limits and API access. Pricing is taken directly from each vendor's pricing page and re-checked when we update the rankings.
