What does the free tier include?

Why use a dedicated free tool instead of ChatGPT?

It seems obvious to just ask ChatGPT to "make this look more human" — but it doesn't work well for three reasons:

• AI writes like AI even when asked not to — it still picks the most statistically likely tokens, producing low-perplexity output
• It can silently change your logic — re-generating code risks subtle bugs, especially in complex functions
• Results are inconsistent — the same prompt gives different outputs each time, with no control over what changes

A dedicated humanizer like Code Humanizer applies targeted, consistent transformations without touching your logic.

Is it safe to paste my code online?

Code Humanizer processes your code in real-time and never stores it on the server. Your code is not logged, not saved, and not used to train any model. It goes in, gets transformed, and comes back — nothing is retained. This is stated in the privacy policy and is enforced at the architecture level (no database writes for code content).

When do I need to upgrade to Pro?

The free tier covers most single-file use cases. Upgrade to Pro ($9/month) if you need:

• More than 12 humanizations per day
• Files longer than 100 lines
• Messy Coder or Senior Dev personas
• API access for automation
