Create an account
Sign up on SuperHumanizer. Your API key and your remaining words both live on this page, so there is nothing else to learn.
Generate your key
One click and it is ready. We show your key once and then store it encrypted, so save a copy somewhere safe. We cannot show it to you again.
Send your first request
Copy one of the examples above, add your key, and run it. Your 1,000 free words are ready to use right away.

You pay for the words you send. No charges per user, no extra fees, no surprises.

Built for production
One endpoint, one request
Send your text, get humanized text back. There is no library to install and nothing to set up first.
The same engine as our app
Your text goes through the same models that power SuperHumanizer. You get the full version, not a smaller one.
Automatic failover
If one model is busy, your request moves to another one on its own. You just get your text back.
Pay for words, not requests
One 5,000 word document costs the same as ten 500 word ones. Send your text however suits you best.
Top up any time
Run out before your month is up? Buy more and the words are added to what you already have, without changing your plan.
No surprise bills
When your words run out, the API tells you and stops. You will never get charged extra for going over.
