Terms of use

Last updated 4 October 2026

Who we are

Quill is a fiction service at quill-app.dev that writes books with you, a page at a time, using AI models. It is run by Milan Konor Nyist, Bosnyák utca C104, 1149 Budapest, Hungary. In these terms "we" and "us" mean Milan Konor Nyist, and "you" means the person using Quill.

By making an account or using Quill, you agree to these terms. If you don't agree, please don't use it.

Your account

You must be 18 or over to use Quill. By making an account, with an email or with Google, you confirm that you are. If we learn that an account belongs to someone under 18, we close it. One account per person. Keep your password to yourself, and tell us if you think someone else has used your account. You are responsible for what happens in it.

Your books and your words

What you write into Quill (your directions, your lines, the Codex you shape) stays yours. The books Quill writes for you are yours too, as far as the law lets anyone own text written with AI. We claim no rights in them. You give us permission to store them, process them and show them to you, and to anyone you choose to share them with, so that Quill can work.

Quill's books are written by AI. They can contain mistakes, and now and then they may echo something already published by coincidence. Read them as fiction, and don't rely on them as fact or advice.

When you share a Codex, anyone with the link or the code can see its plan and start a book of their own from it. Your pages and your own lines are never shared. You can stop sharing it at any time from your account, and books other readers already started from it stay theirs.

What Quill writes, and what it won't

Quill writes romance and fiction for adults, up to real heat and real darkness, but it does not write sexually explicit scenes. Every character in a romantic or sensual scene is an adult, whatever a Codex or a direction says. Please don't use Quill to:

We may stop a request, or suspend an account, that does these things.

How we keep to these rules

The AI models that write for Quill decline some requests on their own, and Quill limits how much can be sent at once and how often. A request that is declined costs no ink. No automated tool removes what you have made or closes an account: a person decides that, and only after looking.

If something you made is taken down, such as a shared Codex, or your account is suspended, we tell you what we did, why, and on what grounds, and you can reply to ask us to look again. You can also go to the courts.

Reporting illegal content

A shared Codex is the one thing in Quill that other people can see. If you think one is illegal, for example because it copies someone else's work or exposes a real person, use Report this Codex under it, or write to hello@quill-app.dev. Say which Codex (its link or code), what is wrong, and why, and give your email. We confirm that your report arrived, a person reads it, and we tell you what we decided and why, and tell the person who shared it too.

For authorities, the European Commission and the European Board for Digital Services, and for anyone using Quill, our single point of contact under the EU Digital Services Act is hello@quill-app.dev. Write to us in English or in Hungarian.

Ink, plans and payments

Writing costs ink: a page, a scene, a chapter or a turn with the Architect each has a price in ink, shown where you choose it. Writing a book yourself, reading, rewinding and restoring are free. Ink is held while a beat is written and only spent when it arrives. A beat that fails, or that the model refuses, costs nothing.

Prices are in euros if you are in the EU or the EEA, and in US dollars everywhere else. The price shown before you pay is the whole price you pay. Payments are handled by Stripe, and we never see your card. Plans renew automatically, monthly or yearly, until you cancel. You can change or cancel your plan any time from your account: it ends at the end of the period you've paid for, and you keep that period's ink until then. We email you a confirmation of every purchase, with these terms attached as they stood when you bought.

Withdrawing from a purchase

If you are a consumer, you can withdraw from a plan or a top-up within 14 days of buying it, without giving a reason.

Before you pay, we ask whether you want Quill to start straight away, and you confirm that you understand you lose the right to withdraw for the ink you use. So if you withdraw, we refund what you paid less the share of that purchase's ink you have used, and withdrawing from a plan ends it. If you never asked us to start straight away, we refund it all.

To withdraw, use Withdraw from contract here in your account, or send us a clear statement at hello@quill-app.dev, for example with the form below. We confirm by email straight away, and refund within 14 days of your withdrawal, the same way you paid.

If Quill doesn't work as it should

Quill must work as these terms and the plans page describe, for as long as you use it. If it doesn't, tell us, and we put it right, free and within a reasonable time. If we can't, or don't, you can ask for a lower price, or end the contract and get back what you paid for the time it didn't work. These are your rights as a consumer under the law on digital services (in Hungary, Government Decree 373/2021), and while we provide the service, it is for us to show that it worked.

Your data

The whole of it is in the privacy notice. In short:

We keep what Quill needs to work: your email address, your books and Codices, your ink and payments, and a record of each call to the AI models. We don't sell it, and we don't use your books to train anything. A few companies run parts of Quill for us and see what they need for that part: Supabase (the database and sign-in, in Ireland), Vercel (the website), Anthropic (the models that write, which do not train on what they are sent), Stripe (payments), Resend (email), Cloudflare (the check that you're a person, and our email) and GitHub (encrypted backups).

Changes, and when things go wrong

Quill is new and will keep changing. We may add, change or remove features, and the service may sometimes be unavailable. If we change these terms in a way that matters, we'll tell you in Quill or by email before the change applies, and the date at the top will change.

We aren't responsible for losses nobody could have foreseen when you started using Quill. Beyond that, our total responsibility to you is limited to what you paid us in the 12 months before the problem. This never limits our responsibility for harm we cause on purpose or through gross negligence, or for harm to anyone's life, body or health, and it never limits your rights as a consumer, or any responsibility the law doesn't let us limit.

Ending

You can stop using Quill at any time, and cancel any plan from your account. To close your account and delete your books, write to us at hello@quill-app.dev. We may suspend or close an account that breaks these terms. If we close yours for any other reason, we'll give you notice and refund any unused paid ink.

If something goes wrong

Tell us first, at hello@quill-app.dev, or from Send feedback in your account. We answer a complaint in writing within 30 days, and if we turn it down, we say why.

If we can't settle it between us, a consumer can go to a conciliation board (békéltető testület), free of charge. Ours is the Budapesti Békéltető Testület, 1016 Budapest, Krisztina körút 99., bekelteto.testulet@bkik.hu, and the board for every county is listed at bekeltetes.hu. You can also turn to the consumer protection authority (in Hungary, the government office where you live, under the Nemzeti Kereskedelmi és Fogyasztóvédelmi Hatóság, nkfh.gov.hu), or to the courts.

The agreement itself

These terms, and the prices shown when you buy, are the whole agreement between us. It is made in English, and it is made electronically: we don't keep a separate signed copy, but these terms stay at quill-app.dev/terms, your purchases are listed under "Where it went" in your account, and every payment's receipt is in Stripe's billing page, one tap from your account. You can check and correct what you enter at every step before you pay. We don't follow any code of conduct.

These terms are governed by the law of Hungary, without taking away any protection the law where you live gives you as a consumer.

Contact

Questions about these terms, or anything else: hello@quill-app.dev. Ideas for Quill are welcome there too, or from Send feedback in your account.

Before you pay

You can withdraw within 14 days. How withdrawing works.
