Question 11

Will my subscription renew automatically?

Accepted Answer

Yes. Please review your purchase carefully before checking out. When you purchased a plan, you're subscribing to a recurring service. That means:
• Your payment method gets charged automatically every month or year (depending on your plan), except lifetime plan (only charge one time).
• All plans renew automatically at the end of each billing cycle unless you cancel before your renewal date.
• It's not a one-time purchase.

We don't issue refunds once a renewal payment goes through. So make sure you pick the plan that actually works for you before buying. Click here to see our Terms of Service and Refund Policy.

Question 12

How can I cancel my subscription?

Accepted Answer

You can cancel anytime via support@gpthumanizer.ai or send cancel request message to us in Dashboard.

Canceling your subscription means that the automatic renewal will be disabled, but you will still have access to all your subscription features for the remaining time of then-current period.

Question 13

Do you offer refunds if I'm unhappy with the platform or the text?

Accepted Answer

No. As stated in our Terms of Service, GPTHumanizer AI is an instant-use digital service. When you humanize text with us, the processing happens right away. This is similar to buying and downloading music or ordering a custom print; there's nothing to "return" once delivered.

Because of this, we don't offer refunds simply for:
• Not like the output text
• Failing a plagiarism or AI detection test
• Forgetting to cancel before renewal

Please review your purchase carefully before checking out. This is also why we offer free Lite model for you to try before making a purchase. We strongly encourage you to try first and check you're selecting the right plan for your needs.

Question 14

Accepted Answer

You may request a refund within 3 days of your initial purchase. To be eligible for a refund, you must meet the following criteria:
• The refund request is made within 3 days of purchase
• You have not used 1000 words of your plan
• You provide a valid reason for the refund request
• Your account is in good standing with no violations of our Terms of Service

⚠️ We review all requests carefully and will reply within 2 business days. We reserve the right to decline refunds if we believe someone is attempting to take unfair advantage of this policy.

Question 15

How does the Humanization technique works?

Accepted Answer

GPTHumanizer uses a multi-layer rewriting engine that performs:
• structural sentence reconstruction
• clause redistribution
• tone and rhythm adjustments
• semantic preservation
• anti-pattern rewriting to reduce AI detector triggers

Instead of synonym swapping, the system rebuilds text in a natural human-like way.

Question 16

Does GPTHumanizer only works for ChatGPT output?

Accepted Answer

No. GPTHumanizer is model-agnostic.
It works on text generated by:
ChatGPT and other OpenAI models
Claude, Gemini, Llama and any other LLMs
In-house / custom AI systems
It also works on mixed text (part human, part AI). The engine focuses on the writing patterns in the text itself, not on which model produced it.

Question 17

How do I reduce false positive on AI-flagged text?

Accepted Answer

No AI detector is perfect, but GPTHumanizer is designed to protect genuine human writing as much as possible.
On our internal evaluation set, our classifier reaches over 99.3% overall accuracy, and because we deliberately bias the system toward "Human" when the evidence is ambiguous, the chance that truly human-written text is wrongly flagged as AI is around 0.1% in our tests.

To further reduce the risk of false positives in real use:
• Use enough text: Very short snippets are statistically noisy. Whenever possible, check at least a few paragraphs instead of one or two sentences
• Avoid heavy AI rewriting on human text: If a human draft has been extensively rewritten by an AI assistant, most detectors (ours and others) may see AI-like patterns. Make sure there is clear human editing and personalization.
• Keep real-world evidence: For important use cases (e.g. academic or professional work), keep drafts, timestamps, and earlier versions as proof of your writing process, these are stronger than any automated score.

Even with strong performance and a human-protective design, we still treat detection as probabilistic, not absolute. If you believe a result is clearly wrong, you can contact us with the text so we can review the case and further improve our calibration.

Question 18

How does GPTHumanizer preserve tone and context?

Accepted Answer

Our rewriting model is trained to preserve intent first, style second, and surface form last:
It keeps the core message, structure, and key facts aligned with the original.
Names, numbers, citations, and important details are treated as "high-priority" anchors and are preserved.
The model mainly changes how something is said (phrasing, rhythm, connectors), not what is said.
When you choose a tone (e.g. more formal, more casual), GPTHumanizer adjusts the style while still respecting your original voice, point of view, and constraints as much as possible. The system is explicitly instructed not to add new claims or hallucinate facts.

Question 19

Does GPTHumanizer support long documents?

Accepted Answer

Yes. GPTHumanizer can work with long-form content such as reports, essays, articles, and chapters.
Under the hood, long documents are processed in smart segments with slight overlaps, so we can:
• keep local coherence within each section
• maintain consistent tone and terminology across the whole document

For very large files, we recommend splitting by logical sections (chapters, headings) both for quality and for easier control over the final result, but you don't need to manually micromanage paragraphs, GPTHumanizer is built to handle long texts reliably.

Question 20

Is my data secure?

Accepted Answer

Yes. All data is transmitted over encrypted connections. We follow industry-standard security practices to protect your text, documents, and account information.

Question 21

How can I change my password?

Accepted Answer

Click Login tab, and click [Forget password] or change password in your dashboard.

Question 22

Is GPTHumanizer AI meant to "bypass" Turnitin or AI detectors?

Accepted Answer

No. GPTHumanizer is built for writing improvement—clarity, tone, and fluency—not for cheating or misrepresenting who wrote the content. If your goal is to deceive a school, platform, or reviewer, please do not use this product.

Question 23

Does GPTHumanizer AI guarantee a "human" result on AI detectors?

Accepted Answer

No. We do not guarantee outcomes on any third-party detector or integrity system. Detection tools can change over time and may produce false positives or inconsistent results depending on the text and context.

Question 24

Can I use GPTHumanizer AI for school or research writing?

Accepted Answer

It depends on your institution’s policy. Many schools allow certain forms of editing support, while others require disclosure or restrict AI-assisted writing for specific assessments. Always check your course rules and follow them.

Question 25

Should I disclose or cite AI assistance?

Accepted Answer

If your school, journal, or employer requires disclosure, you should disclose it. We recommend being transparent whenever rules or expectations are unclear.

Question 26

What’s the safest way to use GPTHumanizer AI ethically?

Accepted Answer

Use it like a writing assistant: revise your own ideas, verify facts and citations, and do a final human review to ensure the work reflects your intent and meets policy requirements.
