What you get
for free.
Every visitor gets a 500-word free trial, shared between the humanizer and the AI Detector. You do not need an account, an email address or a card to use it.
500 words, no account
Enough for a short essay, a cover letter or several emails. Detection uses half the word count, so checks go further.
The same engine as paid plans
The free trial runs the full humanizer, not a cut-down version. In our test, ZeroGPT read all 60 of its rewrites as human-written.
Free tools with no limit
Word counter, character counter, readability and other text-analysis tools are free with no account and no cap.
How to humanize AI text for free
Three steps, no sign-up.
Paste your AI text
Paste up to your free word allowance, or import a TXT, DOC, or DOCX file.
Humanize it
Balanced mode is the default. Choose a purpose and style if you want, or keep the defaults.
Check & copy
Run the AI Detector on the result, read it against your draft, then copy or download it.
What happens after the free words
Nothing is charged automatically, and the free trial never turns into a subscription by itself.
Create an account if you need more
An account saves your revision history. Paid plans start at $9.90 a month for 5,000 words, and a 3-day Pro trial costs $3 for 20,000 words.
Keep using the free tools
Text-analysis tools such as the word counter stay free and unlimited, with or without an account.
Free does not mean stripped down
Every control, from the first word.
Modes, styles, purposes and keywords to keep are all available in the free trial.

Open your historyFree AI humanizers: what to check before you paste
“Free” means different things on different sites. These are the questions worth asking, and our answers.
| Question | Why it matters | RewriteMax |
|---|---|---|
| Do I need an account? | Sign-up walls slow you down and collect your email. | No, not for the first 500 words. |
| Is the free version the real engine? | Some free tiers use a weaker model. | Same humanizer as paid plans. |
| Can I check the result? | A rewrite you cannot check is a guess. | AI Detector included in the free trial. |
| Will I be charged later? | Free trials sometimes renew into paid plans. | No card is asked for, so nothing renews. |

Trial details
20,000 words during the three-day trial. It renews as Pro with a fresh 20,000-word monthly allowance after the first monthly charge; unused trial words expire. This paid trial converts to monthly billing even when yearly plans are selected. Cancel before the next billing time shown in checkout and your receipt to prevent renewal.
Free toolsWord counts, text analysis & draft preparation.
Try free toolsBilling & usage details
Each processing pass may use words. Humanizing and source matching use the ordinary word allowance; AI detection uses half the input count rounded up. Other workflows have their own usage rules in your account. Beyond the 500-word free trial of the humanizer and AI detector, AI processing requires sign-in and an available allowance; free tools do not include a paid humanizer plan.
Annual plans are charged in one yearly payment; the monthly equivalent is for comparison. Included words reset monthly and do not roll over. “Unlimited” is a plan name with a 100,000-word monthly allowance. Buying an allowance does not guarantee a detector score.
Cancel in your account before the next billing time to stop renewal. Cancellation does not refund an earlier charge; refund requests follow the refund policy. Checkout shows your final total, applicable tax and renewal date.
A few things worth knowing
AI Humanizer Free FAQ
What is free, how much, and what happens next.
Is the AI humanizer really free?
Yes, for the first 500 words per visitor, with no account and no card. After that, humanizing uses a paid plan’s word allowance.
Do I need to sign up?
No. The 500-word free trial works without an account. Signing up adds saved revision history and lets you buy a plan.
Does the free trial include the AI Detector?
Yes. The humanizer and the AI Detector share the same free allowance, and a detection uses half the input word count, rounded up.
Open the AI Detector
Is there a free humanizer with no word limit?
Not here, and be careful with sites that promise unlimited free use: costs have to be covered somewhere. Our text-analysis tools are free with no limit; the humanizer is free for the first words.
Browse the free text-analysis tools
Is the free version weaker?
No. The free trial runs the same humanizer as paid plans, with every mode, style and purpose available.
How well does it work?
In our October 2026 test, 60 AI-written texts that ZeroGPT scored 89% AI on average all came back human-written after one Balanced rewrite. Read your rewrite before using it, as any automated rewrite can change details.
