Frequently Asked Questions About the Two Humanize AIs
No. They're separately incorporated companies with different founding teams, different tech stacks, and different pricing models. The names converged because both teams independently picked the most descriptive English phrase for what the product does. We don't have any business relationship with the .ai team.
The category is similar but the implementations diverge. Our rewrite engine targets specific statistical signals the major detectors measure — perplexity, burstiness, sentence-rhythm variance — and retrains weekly against fresh detector benchmarks. Other products in the category sometimes use older paraphrasing methods that pass weaker detectors but fail Originality.ai or Turnitin. Run a side-by-side test on a Turnitin AI score to see the difference.
If you signed up for the .ai version and meant to use this site, contact their support directly — we don't have access to their billing. Most subscription products in the SaaS category honor a refund within the first 7-14 days. As a baseline, our free tier covers most use cases without subscribing to anyone.
Check the URL bar — if the domain ends in .io, you're here; if it ends in .ai, you're on the other one. Bookmark humanize-ai.io directly so search-result variation doesn't send you to the wrong product next time. Search engines occasionally re-rank both versions for the same query.
Neither. Both are independent products. We use various LLM providers under the hood for rewriting (similar to how content tools use multiple model APIs), but we're not built or sponsored by any specific lab.
