By using kudowrite ("the app") or reading on Community Books (section 4), you agree to these terms. Please read them. They are short.
kudowrite is a browser-based fiction-writing tool. It helps writers draft, rewrite, and expand prose using AI: kudowrite's built-in AI, KudoAI, paid for with prepaid credits (section 7), or, if you prefer, models accessed through your own OpenRouter or Mistral account (section 9).
kudowrite also hosts Community Books, a public library where writers can choose to publish their work and anyone can read it (section 4).
kudowrite is run by one person, an individual based in France ("we", "us"). You can reach us at admin@kudowrite.com.
kudowrite is account-based: you sign in, and your writing is stored in a database we operate in the EU so it's available on every device you use. (Earlier versions stored everything in your browser and an optional file in your Google Drive; Drive sync has been removed.) What we do and don't do with that data is set out in the Privacy Policy.
You must be at least 18 years old to create a kudowrite account. The app may generate adult-oriented creative content, and Community Books may contain adult stories. By creating an account you confirm you meet this age requirement. Reading Community Books doesn't need an account; stories rated Mature, Explicit or Not rated are shown only after you confirm you're an adult.
You are responsible for keeping your login credentials secure and for activity that happens under your account. If you think someone else has access to it, email us.
You own everything you write. kudowrite claims no rights over your stories, notes, or anything else you create with the app. We do not sell your work or use it to train AI models, and we never make it public — only you can, by publishing it on Community Books (section 4).
We store your work solely to provide the app to you. You can delete any project, everything you've written, or your whole account from within the app at any time (Settings → Account), and download a copy of your data there too. Deletion is permanent and there is no backup to restore from.
What the AI writes for you. As between you and kudowrite, the text the AI writes for you in the app is yours to use, like the rest of your writing. AI text can be wrong, can repeat common phrasing, and can by chance resemble someone else's writing: where you use or publish it is your decision, and so is checking it doesn't infringe anyone's rights. Some countries don't grant copyright to text a machine wrote on its own, so your rights in it may depend on how much of it is your own work.
You are responsible for keeping your own copies of work that matters to you. See section 10 — kudowrite comes with no warranty, including against data loss.
Community Books is optional. Nothing you write becomes public until you press Publish on a chapter.
You agree not to use kudowrite — the writing app or Community Books — to:
Violation of these terms may result in your content being removed or your access being revoked without notice.
You're responsible for what you write, publish and send. If someone brings a claim against us because of content you published, or because you used kudowrite in breach of these terms, you agree to cover the costs that claim causes us, as far as the law allows.
KudoAI is paid for with prepaid credits. Each AI request deducts credits according to the AI usage it consumes; your balance is shown in the app.
kudowrite runs on Supabase (database and authentication) and Cloudflare (hosting and server functions), optionally uses Google for sign-in, processes payments through Stripe, and sends AI requests to OpenRouter or Mistral. Your use of those services is governed by their respective terms:
kudowrite is not responsible for the availability or behaviour of those third-party services.
Instead of KudoAI, you can use your own OpenRouter or Mistral API key, from Settings. You are responsible for obtaining and securing that key, and any charges incurred on that account are yours. kudowrite stores your key on your account, encrypted at rest, so it works across your devices; it is sent only to the provider you selected, and only to make the requests you ask for. Details are in the Privacy Policy.
kudowrite is provided "as is" without warranty of any kind. The app may contain bugs, go offline, or stop working at any time. We make no guarantees about the accuracy, reliability, or availability of the service or the AI-generated content it produces. Stories on Community Books are written by their writers, not by kudowrite; we don't review them before they're published and aren't responsible for what they say.
To the maximum extent permitted by law, we are not liable for any indirect, incidental, special or consequential damages arising from your use of the app — including loss of data or content — and our total liability for any claim about kudowrite is limited to what you paid us in the 12 months before it (or €50 if you paid nothing). Nothing in these terms limits liability that the law doesn't allow us to limit, such as for fraud, gross negligence, or death or personal injury caused by negligence, or takes away your rights as a consumer. Keep your own copies of anything you can't afford to lose.
KudoWrite, KudoAI and the kudowrite logo are ours. Please don't use them in a way that suggests we endorse you or your work.
Other product, company and fandom names that appear on kudowrite — in our guides and comparisons (such as Sudowrite, NovelAI, Novelcrafter or ChatGPT), and the books, shows and games stories are based on — are trademarks of their owners. kudowrite is an independent product, not affiliated with, sponsored or endorsed by any of them; we name them only to describe or compare.
We may update these terms. For a change that matters, we'll tell you in the app or by email at least 15 days before it applies; if you don't agree, you can close your account before then. Using kudowrite after a change applies means you accept it. The "Last updated" date shows when they last changed.
These terms are governed by French law. If you're a consumer, you keep the protection of the mandatory rules of the country where you live, and you can bring a claim before its courts. Before going to court, please write to us: most problems are solved with an email.
These terms and the Privacy Policy are written in English; other languages are translations for convenience. Where a translation differs, the English version applies, as far as the law allows.
