We make AI writing
sound human again.
HumanGPT is a free AI humanizer. You paste text from ChatGPT, Claude, or Gemini. We rewrite it so a person reading it would believe a person wrote it. Detectors stop flagging it. Your meaning stays the same. Your voice gets sharper. That is the entire product.
A tool we wanted that no one else was making properly.
Look. The AI writing wave hit fast. Two years ago nobody had heard of GPTZero. Now every university runs Turnitin AI checks on every submission. Every blog you read got drafted in ChatGPT first. Every cold email is one click away from being the same paragraph everyone else sent.
That created a real problem for real people. Students who wrote their own essays got flagged because they happened to write cleanly. Bloggers watched their traffic collapse because Google demoted anything that read like AI. Marketers got chewed out in standup for sending campaigns that "felt off."
The tools that existed were not great. They were either expensive subscription-only services that priced students out, or free tools that produced garbage output that literally read worse than the AI input. A few were just paraphrasers in a fresh coat of paint, which fooled exactly nobody.
We figured we could do better. We had the engineering chops, we had the SEO instincts from a decade of building free tools, and we had a clear opinion: the right humanizer preserves your meaning, varies your rhythm, and gets out of your way.
So we built it. Free 200 words a day, forever. Pro tier for the people who need volume. A 100-seat Founders edition for the people who want to support the project early. That is the whole business.
Six rules we wrote down before we wrote any code.
- 01
Free should mean free.
Free tier never expires. No credit card to start. No tricks. The Pro plan exists for users who push past 200 words a day, not as a paywall on the basic experience.
- 02
We test against detectors, weekly.
Every Monday we run a fresh sample through GPTZero, Turnitin, Originality.ai, Copyleaks, ZeroGPT, Sapling and Winston. Bypass numbers stay public on the FAQ. When they slip, we patch.
- 03
Meaning stays. Voice changes.
A humanizer that rewrites your essay's argument is broken. We tune for variance and rhythm, not synonym swapping. Your facts, names, dates, and citations come out the way they went in.
- 04
No marketing fluff in the product.
Buttons say what they do. The free tier says it's free, every day, no signup. The Pro plan says exactly what you get. The Founders deal says 100 seats and means it. No false urgency.
- 05
Native speakers, not Google Translate.
Each of the 30+ languages was tuned by people who actually write in that language. Spanish flows differently from Polish. Japanese reads differently from Arabic. We do not auto-translate.
- 06
We answer our own emails.
Real responses, usually inside a few hours. No bot triage. No 'we received your ticket' auto-reply. Reply to your receipt and a human gets back.
