Frequently asked questions
What does Grade A Humanizer do?
It rewrites AI-sounding text so it reads more naturally and human, and it lets you scan documents for AI-written content.
Do you store my text or my results?
No. Your input, the humanized output, and detection results are processed in memory and discarded after each request. We don't save your documents.
Do I need to verify my email to sign up?
Yes — when you register with an email and password we send a 6-digit code to confirm it's really you. Signing in with Google skips this step, since Google already verified your email.
Which browsers are supported?
Any modern browser — Chrome, Edge, Firefox, Safari, and mobile browsers. Internet Explorer is not supported.
What's the difference between Model 1 and Model 2?
Model 1 (the default) is balanced — it reads naturally and stays undetectable, so it's the best choice for most text. Model 2 is tuned purely to stay undetected, so reach for it if a result still gets flagged as AI. Either way, you can run “Make all green” to clean up any sentences that are still highlighted.
I humanized my text, but it's still being detected as AI. Why?
Some sentences are tougher than others. Try a higher Level, use “Make all green” to re-pass any sentences that are still flagged, or humanize again to explore different phrasings for your text.
What do the rewrite Levels mean?
The Level controls how much variation the humanizer tries per sentence. Higher Levels explore more rewrites (more variation, a bit slower); lower Levels stay closer to your original and run faster.
Which Level should I start with?
Level 8 is a good default. If the output drifts too far from your meaning, lower it; if sentences still read as AI, raise it or use “Make all green”.
The output is hard to read or feels off. How do I fix it?
Lower the Level so rewrites stay closer to your original, or humanize again to try a different phrasing. It protects your facts, names, and numbers, so it won't invent details.
What is “Make all green”?
It keeps re-rewriting only the sentences still flagged (yellow/red) until they read as human (green), they stop improving, or a safe limit is reached. It doesn't count against your daily humanization limit.
Does it change my facts, names, or numbers?
It aims to keep your meaning. It will not introduce new names or numbers — if it can't rewrite a sentence faithfully, it leaves it unchanged.
Does it remove dashes?
Yes — the humanizer strips dash punctuation (which AI tends to overuse) from the output, while keeping real compound-word hyphens like “well-known”.
How long does humanizing take?
A few seconds for short text, longer for full documents, since everything runs on our GPU. Lower Levels are faster.
How does the AI detector work?
It's a model calibrated on real Turnitin reports. For uploaded files it scans each sentence multiple times (alone and within several context sizes) and averages the results for stability.
Is the detection the same in the Humanizer and the file scan?
Both use the same trained model. The file scan runs a deeper, multi-pass, context-aware analysis for the most thorough results.
How accurate is it?
Our detector is calibrated on real Turnitin reports and scans every document in multiple passes, making it highly reliable at identifying AI-written content.
What files can I upload?
Word (.doc/.docx), PowerPoint (.ppt/.pptx), and PDF. Whatever you upload is converted to a clean PDF, and the downloadable report keeps your layout and figures and highlights the parts detected as AI.
Does the report keep my formatting and figures?
Yes — highlights are drawn directly onto your original document, so your formatting, figures, and page count are preserved.
What plans are available?
Free, Basic, Standard, and Premium. Higher plans raise your daily humanizations and words-per-humanize, and unlock the Turnitin scan and priority support.
Is it free to use?
Yes — the Free plan lets you humanize a limited amount each day. See the Pricing & Plans page for exact limits.
Do I need a paid plan for the Turnitin scan?
The Turnitin scan is included on the Standard and Premium plans.
What does Premium include?
Unlimited humanizations per day, the highest words-per-humanize, the Turnitin scan, and priority support.
What are the daily limits?
Free gives you unlimited humanizations with a total budget of 500 words per day. Paid plans raise the per-humanize word limit and remove the daily word cap. Exact numbers are on the Pricing & Plans page.
Is there a word limit per humanize?
Yes — each plan has a maximum number of words per single humanize. If your text is over the limit, shorten it or upgrade your plan.
Does “Make all green” count against my daily limit?
No. Re-passing the flagged sentences with “Make all green” is part of refining one humanization and doesn't use extra daily credits.
Can I make a new free account to get more usage?
We'd ask you not to. Limits keep the service fast and fair for everyone — please upgrade your plan if you need more.
How do I upgrade my plan?
Open the Pricing & Plans page and choose a plan. Online payments are being rolled out — if you don't see a checkout yet, contact support to upgrade.
Can I cancel anytime?
Yes. You can cancel whenever you like; you'll keep your plan's features until the end of the current billing period.
