1. The service
HumanFlow is a writing aid that rewrites text to read more naturally and estimates how AI-like text sounds. It is provided on an "as is" and "as available" basis.
2. No guaranteed results
HumanFlow does not guarantee any result with any AI detector, grading system, or third-party tool. Detection scores shown in the app are estimates for guidance only, and different tools may reach different conclusions.
Output is not legal, medical, financial, or academic advice. A rewrite can shift a nuance, mangle a citation, or change a meaning you needed kept. Read what comes back before you use it — the judgement stays yours.
3. Acceptable use
Our Acceptable Use Policy forms part of these terms. You agree not to use the app for unlawful, infringing, or harmful content, and to comply with the rules of any institution or platform you submit work to. You are responsible for the content you submit and for how you use the results.
If your school, university or employer restricts AI assistance, their rule applies to what you do here. Using HumanFlow does not make submitted work compliant with a rule that forbids it, and we do not sell a way around one.
You may not use HumanFlow to commit academic fraud, or to misrepresent who wrote something where a third party requires that to be disclosed. That covers an institution's academic-integrity rule, an employer's or a client's disclosure requirement, and any platform that asks whether content is AI-assisted. Doing it is a breach of these terms whether or not anybody finds out.
4. Your account
You must be at least 18 to hold an account, or have your parent or guardian's permission. You are responsible for activity under your account and for keeping your credentials secure. You may delete your account at any time (see Delete account).
5. What you submit, and what you get back
You keep ownership of the text you submit. You grant us permission to process it for one purpose only — producing the result you asked for — and that permission ends when the processing does. We do not use it to train any model.
You own the output. To the extent a rewrite attracts any rights, we assign them to you. Use it commercially, publish it, edit it; we claim nothing and ask for no credit.
You confirm that you hold the rights to what you submit, or that your use of it is otherwise lawful, and that you are not submitting other people's personal, confidential or special-category information without the right to do so. Full detail in our copyright policy.
HumanFlow itself — the software, the detector model, the interface, the writing on this site and the name — remains ours.
6. Plans, payment and renewal
HumanFlow has a free plan and paid subscription plans. Prices are shown on the pricing page. Every plan, including the free one, runs the same humanizer and the same detector. Plans differ by monthly volume, and by one detector feature: the sentence map, which highlights every scored line in your text, is included on the paid plans only.
Subscriptions renew automatically. A monthly plan renews every month and a yearly plan every year, at the price shown when you subscribed, until you cancel. We charge the payment method you gave us at the start of each period.
Cancelling. You can cancel at any time from your account. There is no contract term and no cancellation fee. Cancelling stops the next renewal; it does not end the period you have already paid for, and you keep your plan until that period runs out.
Refunds. Our refund policy forms part of these terms, including the 14-day window on a first payment and on a renewal you did not intend.
Price changes. If we change the price of a plan we will tell you by email before it takes effect, and it will only apply from your next renewal — never mid-period. If you do not want the new price, cancel before that renewal.
Allowances. Paid plans include a monthly word allowance for humanizing and for detection. Allowances reset at the start of each calendar month and unused words do not carry over. If you reach an allowance we will tell you; we do not charge overage without your agreement.
Failed payments. If a renewal payment fails we will retry it and email you. If it keeps failing we may suspend the paid plan; your account and your history stay intact and revert to the free plan's limits.
Where you buy a subscription through the Apple App Store or Google Play, that store takes the payment and its own terms govern billing, renewal and refunds. Manage or cancel those subscriptions in the store, not here.
7. Suspension and termination
You may stop using HumanFlow and delete your account at any time. We may limit, suspend or close an account that breaches these terms or the Acceptable Use Policy. Where a breach looks like a misunderstanding we will tell you before we act; where it involves harm to a person we act immediately. Accounts closed for a breach are not refunded.
If we discontinue the service entirely, we will give reasonable notice and refund any period you have paid for and not used.
8. Changes to the service and these terms
We may update, add, or remove features, and may revise these terms. For material changes we will give notice by email or in the app before they take effect. Continued use after that means you accept them; if you do not, you may close your account and we will refund any unused paid period.
9. Warranties
HumanFlow is provided as is. To the fullest extent the law allows, we exclude implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the service will be uninterrupted or error-free, that results will meet your requirements, or that any detector, institution or third party will accept the output.
Nothing in this section removes rights you have as a consumer under the law of your own country.
10. Liability
We do not exclude liability for death or personal injury caused by our negligence, for fraud, or for anything else that cannot lawfully be excluded.
Subject to that, and to the fullest extent the law allows: we are not liable for indirect or consequential loss, loss of profits, loss of data, or loss arising from your use of output — including any academic, disciplinary, employment or publication consequence. Our total liability for any claim is limited to the greater of the amount you paid us in the twelve months before the claim, or US $50.
If you are a consumer, this limit applies only so far as your local law permits. Where local law gives you more, local law applies.
11. Indemnity
If you use HumanFlow in breach of these terms or the Acceptable Use Policy and that causes a third-party claim against us, you agree to cover the reasonable costs of dealing with it. This does not apply to consumers acting outside a trade or profession, except where local law allows it.
12. Governing law and disputes
These terms are governed by the laws of the State of Wyoming, USA, and the state and federal courts sitting in Wyoming have jurisdiction.
If you are a consumer resident in the EEA, the UK, or another country whose law says otherwise, that choice does not deprive you of the mandatory protections of your own law, and you may bring proceedings in your local courts. EU consumers may also use the European Commission's online dispute resolution platform. We would rather you emailed us first — most things are a misunderstanding and we would like the chance to fix it.
13. General
If any part of these terms is found unenforceable, the rest continues to apply. Not enforcing something once does not waive our right to enforce it later. You may not transfer your rights under these terms; we may transfer ours if the business is sold, and your rights are unaffected. These terms, together with the policies they reference, are the whole agreement between us. We send notices to the email on your account.
