A humanizer that does not just run it through ChatGPT
Most humanizers hand back whatever the model returns. TurnItHuman runs a pipeline: mechanical fixes, a dedicated humanizer pass, and checks for meaning and detector risk before you see anything.
Sample readout. Illustrative values from the example job in our API documentation. They show what a result looks like, not a measured outcome.
How it works
Six steps, from cleanup to delivery
Every job runs the same 6 steps: a cleanup, a dedicated humanizer pass, then checks for detector risk and meaning before you see anything.
01·Prepare
Clean up first. Protect what must not change.
Your draft is normalized before the humanizer sees it. Code blocks and reference lists are held back from the humanizer, and citations, quotes and your protected terms are checked after it.
Code blocks and reference lists never go to the humanizer
Add your own protected terms, such as names or titles
Every automatic fix is listed in the result
Clean up
Normalizes spacing and formatting, confirms the text is English, and holds code blocks and reference lists back from the humanizer so they come back as written.
Mechanical fixes
Replaces dashes, curly quotes, filler openers and stock phrases with plain alternatives.
An AI probability estimate from detectors like GPTZero, banded as reads as human, possible AI or likely AI. Standard and Premium can also measure the text before it is humanized.
Choose the strength on paid plans: Quality, Balanced or More Human
Under 50 reads as human, 50 to 60 possible AI, over 60 likely AI
An estimate, never a promised score
Humanizer pass
A dedicated humanizer model reworks your text at the strength you picked. On Standard and Premium it can match a writing sample you registered.
Detector check
Measures the result with a multi-detector estimate. A high estimate can trigger one more attempt.
Numbers, names, citations, quotes, links and your protected terms are compared with your original, and the text as a whole is scored for similarity. You get the humanized text with a short list of the ones that look changed, so you can check them before you use it.
A word-level diff of every change
Copy the result, or export .txt and .docx on paid plans
Developer API with up to 2 keys on Premium
Meaning check
Compares numbers, names, citations, quotes, links and your protected terms with your original and scores the text as a whole for similarity. Those that look changed are listed with the result so you can check them.
Deliver
You get the text, a word-level diff, the scores and any warnings, with copy and export buttons.
