Terms of Service

By accessing or using Muze Writer (“the Service”), you agree to be bound by these Terms of Service. If you disagree with any part of the terms, you may not access the Service. The Service is operated by the French legal entity identified on our legal notices page.

Muze Writer is an AI-powered creative writing platform. We provide tools for drafting, editing, and organizing written content using large language models from third-party providers.

You are responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account. You must immediately notify us of any unauthorized use of your account.

You must be at least 15 years old to use the Service (in line with French law on minor consent to digital services). Users between 15 and 18 must have parental authorization.

The Service offers a free tier (“Reader”) and two paid subscription tiers (“Writer” and “Studio”) on monthly or annual cadences. Paid tiers also include one-time credit add-on packs for spike months.

The price shown on the pricing page is the total amount charged. At launch the Service operates under the French franchise en base de TVA (article 293 B of the French Tax Code), so no VAT is currently collected. Invoices carry the notice “TVA non applicable, art. 293 B du CGI”. If we exceed the regulatory thresholds we will register for VAT and the EU One-Stop Shop (OSS); subscribers will be notified by email at least thirty days before VAT begins appearing on invoices, and the inclusive-of-VAT price will remain the same.

Payments are processed by Stripe Payments Europe Ltd. We do not store payment card details.

Subscriptions renew automatically at the end of each billing period (monthly or annual) for the same duration and at the price then in effect, unless you cancel before the renewal date.

For annual subscriptions, in accordance with Article L. 215-1 of the French Consumer Code (loi Châtel), we will send you a reminder by email at least one month and at most three months before the renewal date. The reminder will inform you of your right not to renew the contract.

If we fail to send this reminder within the legal window, you may terminate the contract at any time, free of charge, with effect from the renewal date. Any sums paid in advance after the renewal date will be refunded within thirty days.

You can cancel a subscription at any time from the “Manage subscription” button in your account settings, which opens the Stripe billing portal. Cancellation takes effect at the end of the current paid period — you keep access to the paid tier until then, and you will not be charged again.

As a European Union consumer, you have a fourteen-day right of withdrawal from the date the subscription contract is concluded (Articles L. 221-18 and following of the French Consumer Code).

Express waiver for immediate access: the Service is a digital content that begins delivery as soon as your account is activated. By clicking the “Subscribe” button at checkout and accessing the Service, you expressly request that performance begin before the end of the withdrawal period, and you expressly waive your right of withdrawal under Article L. 221-28, 13° of the French Consumer Code.

This waiver does not affect your right to cancel future renewals at any time under Section 5.

One-time credit packs are non-recurring purchases. Credits never expire and remain on your account indefinitely. In accordance with the express waiver in Section 6, credit purchases are final once the credits have been added to your account.

Monthly credit allocations granted as part of a paid subscription tier are not refundable in cash on cancellation; they remain on your account and can continue to be spent on AI features even after the subscription returns to the free tier.

You may always contact us at billing@muzewriter.com if you believe a charge was made in error. We review refund requests on a case-by-case basis.

You retain ownership of all content you create using the Service. By using the Service, you grant us a limited license to process your content solely to provide the Service to you.

We do not use your manuscripts to train our AI models. Your drafts are processed only to fulfill your generation requests and are not shared with third parties except as strictly required to provide the Service (e.g., sending prompts to AI providers — see Section 10).

Transactional emails. We send service emails required to operate your account — verification links, password resets, invoices, billing notices, and the loi-Châtel renewal reminders described in Section 5. These cannot be unsubscribed from while your account is active because they are necessary to perform the contract.

Product updates and craft-focused content. We may also send you occasional emails about Muze Writer itself — new features, writing-craft essays, and tips that help you make better use of the Service. As an existing account holder, you may receive these on the basis of the soft opt-in for similar services permitted by Article L. 34-5 of the French Postal and Electronic Communications Code (and equivalent provisions in other EU jurisdictions), and on our legitimate interest in keeping our users informed (Art. 6.1.f RGPD).

One-click unsubscribe, always. Every such email carries a clear unsubscribe link. You can also opt out at any time from your account settings or by emailing privacy@muzewriter.com. Unsubscribing does not affect transactional emails.

No third-party marketing. We never share, sell, or rent your email address to third-party advertisers. We do not send marketing on behalf of other companies.

New accounts created on or after 20 May 2026 are asked to opt in to product updates with a separate, unticked checkbox at signup, in line with the consent rules of the RGPD.

You agree not to use the Service to:

• Generate content that is illegal, harmful, or violates the rights of others
• Attempt to circumvent credit limits or access controls
• Reverse engineer, scrape, or systematically extract data from the Service
• Use the Service in any way that violates applicable laws or regulations

The Service uses AI models from third-party providers (Anthropic, OpenAI, Google, DeepSeek). Your use of AI features is also subject to those providers’ terms of service. If you supply your own API keys (“Bring Your Own Model”), you are solely responsible for compliance with those providers’ terms and for any charges they invoice you directly.

The Service is provided “as is” without warranties of any kind, except for the legal warranties that cannot be excluded under applicable consumer law (warranty of conformity, warranty against hidden defects, Articles L. 217-3 and following of the French Consumer Code). AI-generated content may contain errors, inaccuracies, or inappropriate material. You are responsible for reviewing all AI output before use.

To the maximum extent permitted by law, Muze Writer shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the Service. Nothing in these terms limits our liability for gross negligence, willful misconduct, death, or bodily injury, or any other liability that cannot be excluded under applicable mandatory law.

We reserve the right to modify these terms at any time. We will notify users of significant changes via email at least thirty days in advance. For subscribers, any change to recurring price or subscription features takes effect at the next renewal — you can cancel before that date if you do not accept the change.

Before going to court, you are invited to contact our customer service at hello@muzewriter.com to seek an amicable resolution.

As a French consumer, in accordance with Article L. 612-1 of the French Consumer Code, you have the right to refer the dispute free of charge to a consumer mediator. The mediator we refer to is named in our legal notices.

You may also use the European Commission’s Online Dispute Resolution platform at ec.europa.eu/consumers/odr.

These terms are governed by French law. In the absence of an amicable resolution, the courts of the jurisdiction of our registered office shall have jurisdiction, subject to mandatory consumer-protection rules that may grant a consumer a different forum.
