The service
Humanizer Run provides English writing checks and candidate rewrites. You retain responsibility for the text you submit and publish. You must have permission to submit it. Do not use the service to infringe rights, abuse other people, compromise systems or violate rules that apply to your work.
The style index is not an AI-authorship probability. We do not guarantee detector bypass, originality, factual accuracy or preservation of every detail. Read and verify each revision before relying on it. The service is not a substitute for a qualified professional where one is needed.
Accounts
Keep your account credentials secure. Email registration requires verification. Free allowances are intended for genuine new users; creating multiple accounts or using automation to evade limits may lead to restrictions. API access and bulk automation are not included in the first public version.
Word allowance and purchases
A new account receives 2,500 words of allowance. The one-time word pack costs US$8, or €8 in supported euro pricing regions, and adds 500,000 words. The final currency and any applicable tax appear at checkout. Purchased allowance does not expire and does not renew automatically.
Checking uses one allowance word per input word. Rewriting includes a meaning review and a style recheck and uses two allowance words per input word. Each operation rounds up to a five-word block. Local rewriting charges only the selected input; surrounding context helps interpretation. Each new generation is a new operation. Copying, downloading, accepting and undoing use no allowance.
Documents may contain up to 5,000 words and 40,000 characters. To keep requests manageable, this version accepts up to 400 sentences and 200 paragraphs per operation. Split unusually fragmented documents into sections. Limits are checked before processing. Failed operations restore their reserved allowance; interrupted requests may require recovery before the balance updates.
Billing problems and refunds
If a duplicate charge, technical failure or an unusable purchase occurs, contact support@humanizer.run with your account email and transaction reference. Do not send card numbers. We will review the transaction and remaining usage to determine a correction or refund. Any rights that cannot lawfully be excluded remain applicable.
Availability and changes
We may maintain or change the service and address abuse or security incidents. Third-party outages can prevent checks or rewrites. Keep your own copies of important drafts. We do not promise uninterrupted access or that the editor will be suitable for every document.
Prices and package terms shown when you buy govern that purchase. Changes to future offers do not retroactively reduce your purchased word allowance. Our privacy policy explains data processing. Contact support with questions before buying.
