Naming Collision — Updated April 2026

Humanize AI.io vs Humanize AI.ai

Two unrelated companies, same product category, near-identical name. It happens — both teams registered domains within months of each other in 2023, and Google ranks them both for 'humanize ai.' This page explains the differences honestly, including the cases where the other product is the better fit. You landed on the .io version; here's how it stacks up.

Frequently Asked Questions About the Two Humanize AIs

Are the .io and .ai versions made by the same company?

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.

If both products do the same thing, why are the results different?

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.

I started a subscription with the wrong one. Can I get a refund?

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.

How can I tell which version I'm on at any given time?

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.

Is one of these affiliated with OpenAI, Anthropic, or another big AI lab?

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.
