HumanTone™.
The Professional AI Humanizer.
HumanTone rewrites AI generated text so it reads like a person wrote it. We started in 2025 with one goal: real semantic rewriting instead of synonym swaps and tricks. Today 40,000+ people use HumanTone to edit drafts from ChatGPT, Claude, Gemini and other AI tools in 60+ languages.
Founded by Andrew, SEO specialist and full stack developer.

Our story
Built on a Problem.
Andrew worked in SEO and wrote code for a living. AI drafts saved him hours, but every draft needed heavy editing before it could go live. The tools he tried for that job swapped words, added typos or hid characters in the text. The result still read like AI, and sometimes worse.
So he built his own. The first version of HumanTone was ready in June 2025, and the public launch followed in July 2025. The idea has not changed since: rewrite the structure of the text the way an editor would, and keep the meaning.
Since then HumanTone has grown from one rewriting tool into a full set of tools for professional content work: the Humanizer, an AI likelihood checker, free text utilities, a public API and integrations for developers.

How it works
Real Rewriting. No Tricks.
HumanTone reads the whole text first, then rewrites it. Sentence structure, rhythm and word choice change, while facts, numbers and key terms stay in place. That is the difference from a paraphrasing tool, which swaps synonyms and keeps the same AI structure underneath.
Custom Instructions.
Set the tone, audience, purpose and the terms that must not change. Every rewrite in the project follows them.
Three Levels.
Standard works in 60+ languages. Advanced and Extreme are available for English.
AI Likelihood Score.
Each result comes with an AI likelihood score, so you can check the text before you publish it.
Saved Projects.
Every humanization is saved with its settings. Come back later, compare versions and rewrite again.
We do not swap characters, insert typos or add hidden symbols to trick software. Our Hidden Symbols Finder does the opposite: it finds them and removes them.
What we stand for
One Standard for Every Text.
No Tricks. Real Rewriting.
We don't swap characters, inject typos, or game detection systems. We do actual semantic rewriting, restructuring content so it reads differently because it genuinely is different.
Written for People, Not Detectors.
Our focus is content that works for real readers: natural rhythm, the right tone, clear points. Lower AI detection scores follow from that, but they are not the goal.
60+ Languages, One Standard.
Every language we support gets the same rigorous rewriting approach. Consistent quality and natural phrasing, whatever language you publish in.
Built for Professionals.
Content teams, SEO specialists, agencies, writers. People who publish at scale and need consistent quality, not a quick fix that breaks under volume or scrutiny.
We build HumanTone for better writing, not for passing off work dishonestly. Read how to use HumanTone responsibly.
For developers
Built to Integrate.
Everything the Humanizer and the AI detector do in the app is also available in code. The public API at api.humantone.io uses the same credits as your account. The MCP server connects HumanTone to AI assistants and agents, and the official Node.js SDK is on npm.
