Use the AIHT Rating to build a shortlist, then follow the evidence into the review. The October 2026 edition is an editorial baseline. It does not represent a new benchmark run.
These are checks for choosing a tool, not measured component scores or an unpublished weighting formula.

Six tools from the current rating register. Each score links to its record; the review and badge carry the same edition. These are editorial ratings, not detector pass rates.

Practical answers to the questions behind the purchase.
An AI humanizer rewrites existing text to change its phrasing, sentence structure and tone. The useful result is clearer writing that preserves the original meaning. It still needs a human check for accuracy, context and voice.
Start with your use case and budget, then shortlist two tools. Run the same representative draft through each, compare factual accuracy and readability, and check the editing work left. Our directory and individual reviews are starting points for that decision.
A free option can help you try a workflow before paying. Check its word allowance, per-run limit, available modes and whether access resets or is a one-time trial. Confirm the provider's current terms before building a regular workflow around it.
No detector result should be treated as a guarantee across all tools or future checks. A rewrite can also introduce errors or lose your meaning. Judge the writing itself and follow the disclosure rules that apply to your work.
Read the methodology alongside any score. The original sample files, detector-run logs and a reproducible scoring formula are not published here, and some older pages use different datasets. Published scores are a reference point, not a promise about your own results.
Check your institution and course rules first. Where editing assistance is allowed, keep your own ideas, sources and draft history, and disclose AI use when required. A detector score does not determine whether an assignment follows those rules.
