Terms of Service

Version 2026-09-01 · Last updated 13 September 2026

Before you start

Nautilus gives you legal information, not legal advice. The answers are written by an AI system, they can be wrong or out of date, and no lawyer has checked them. Nobody at Nautilus becomes your lawyer, and your conversation with us is not protected the way a conversation with your own lawyer would be. Check anything important with a qualified lawyer before you act on it.

Section 9 (what Nautilus is not) and section 13 (liability) are the two you should actually read.

1. Who these terms are between

These terms form a contract between you and LEGAL ENTITY NAME, legal form, registered at REGISTERED ADDRESS, company number NUMBER ("Nautilus", "we", "us"). "You" means the person using the service.

By creating an account or using Nautilus you accept these terms. If you do not accept them, do not use the service.

Two kinds of account

Firm accounts are seats provided through an organisation — a law firm, an in-house team, a company. Where your organisation has signed a separate written agreement with us, that agreement governs and these terms fill the gaps. The Data Processing Agreement at nautilus.legal/dpa forms part of it.

Consumer accounts are opened by private individuals for their own purposes. Sections marked (consumers) apply only to you; sections marked (firms) apply only to organisational seats. Consumer accounts never receive a Data Processing Agreement, and are never asked to warrant a lawful basis for their own data.

2. What Nautilus does

Nautilus searches a curated database of legislation and court decisions, and uses an AI model to produce, from the provisions it finds:

legal research answers, citing the sources they rest on;
document drafts;
arguments for or against a position;
summaries of material you provide.

The service covers the legal domains listed in your account: currently maritime law (English), Swiss labour law (German), Montenegrin law (Serbian) and Dutch law (Dutch). Coverage differs by domain and changes over time. Some areas of law are deliberately out of scope — see section 9.3.

3. Eligibility and your account

You must be 18 or over to hold a consumer account, and you confirm this at registration. Nautilus is not intended for children.
Registration currently requires a valid invite code.
You must give a real email address and verify it. Until you do, you cannot sign in.
One account is for one person. Do not share your credentials, and do not let someone else use your seat.
Keep your password safe. You are responsible for what happens under your account until you tell us it has been compromised. Tell us promptly at support@nautilus.legal if you think it has.
You may sign in with Google instead of a password. We do not link a Google identity to an existing account unless both email addresses are verified — if they are not, you will be asked to sign in with your existing credentials first, deliberately.
Do not rely on Google as your only route in. If you lose access to your Google account you must still be able to reach your own files, so add a password as well.

(firms) Whoever administers your organisation's account controls which seats exist and may close yours. Ask them, not us, about access to material created through a seat.

4. Your allowance and paid plans

Each account carries a usage allowance, expressed in euros and consumed as you use the service. When the allowance is exhausted the assistant stops answering until it is topped up or renewed. Usage is metered per request and is visible in your account.

Payments are not live. When they are, this section needs: prices inclusive of VAT, the billing cycle, renewal and cancellation mechanics, the withdrawal waiver in section 5, invoice retention in the Privacy Notice, and an unfair-terms review of the whole document (I-05 in the compliance plan). Do not publish a paid tier on this text as it stands.

Nautilus is currently provided free of charge within the allowance on your account. We may introduce paid plans; we will tell you before we do, and you will never be charged without agreeing to a price first.

5. Your right to change your mind (consumers)

Where you buy a paid plan, EU consumer law gives you 14 days to withdraw without giving a reason.

If you ask us to start providing the service immediately — within those 14 days — you must expressly request that and acknowledge that you lose the withdrawal right once we have fully performed. We will ask you for that acknowledgement at the point of purchase, separately and clearly. If you do not give it, delivery starts after the 14 days.

To withdraw, tell us at support@nautilus.legal. No form is required.

This section has no effect while the service is free of charge.

6. What you may use Nautilus for

Use it to research a legal question, prepare a document, or understand your position. That is what it is for.

Do not:

use it for anything unlawful, or to plan, facilitate or conceal anything unlawful;
upload material you have no right to share, or that you are barred by confidentiality, privilege or court order from disclosing;
upload personal data about other people beyond what the question genuinely needs — see section 7;
try to make the assistant produce unlawful, defamatory or harmful content, or work around the limits in section 9.3;
scrape, bulk-extract, resell or redistribute our database, or use the output to build a competing product or to train a machine-learning model;
probe, overload, reverse-engineer or circumvent the security of the service, or use automated tooling against it without our written consent;
impersonate anyone, or misrepresent your relationship to a matter;
share your account, or resell access to it.

(firms) You remain bound by your own professional conduct rules, including your duty of confidentiality and your duty to check work before it goes to a client or a court. Nothing here displaces them.

7. Your content

You keep everything. The questions you write, the documents you upload and the drafts you generate remain yours. We claim no ownership of them.

You grant us only the licence we need to run the service: to store, process, transmit and display your content in order to answer you, and to send it to the processors listed in the Privacy Notice for that purpose. That licence ends when you delete the content or your account.

We do not use your content to train, fine-tune or evaluate AI models. If we ever want to, we will ask for your explicit opt-in consent, separately, and a refusal will change nothing about the service you receive.

What you promise about what you upload

You confirm that you are entitled to share what you upload, and that doing so does not breach a confidentiality obligation, a privilege, a court order or anyone else's rights.

Minimise. Legal questions often involve other people — a colleague, an employer, a family member, an opposing party. Include what the question actually requires and leave out the rest. Where you can pose the question without naming someone, do.

(consumers) Because we are the controller of what you type, we ask for your explicit consent before processing the sensitive parts of it, and you can withdraw that consent in one click. See section 3 of the Privacy Notice.

8. Output

Answers, drafts, arguments and summaries generated for you are yours to use, subject to these terms. We claim no copyright in them.

Two honest caveats:

AI output is not unique to you. Similar questions produce similar answers, and we cannot promise that what you receive is original or that someone else will not receive something very like it.
Quoted legal sources are not ours to license. Legislation and court decisions carry their own conditions of reuse, and the citations in an answer are reproduced from public sources.

9. What Nautilus is not

9.1 Not legal advice, and not a lawyer

Nautilus provides legal information. It does not provide legal advice, it does not represent you, and using it does not create a lawyer–client relationship with anyone. It does not know the full facts of your matter, it cannot weigh what you have not told it, and it cannot take responsibility for a decision.

(consumers) This matters more for you than for a law firm using the same product. Your conversation with Nautilus is not privileged. It would not be protected from disclosure the way a conversation with your own instructed lawyer would be. If your matter is serious, instruct a lawyer.

9.2 AI-generated, and fallible

Every answer is produced by an AI system from the sources it retrieved. You are told this with every answer, as EU law requires. It means:

an answer can be wrong, incomplete, or confidently mistaken;
a cited provision may be misread, or a relevant one missed entirely;
the law may have changed since our database was last updated, and a provision shown as in force may not be;
coverage varies by domain and is not exhaustive of any jurisdiction.

Check the cited provisions yourself before you rely on them. They are cited precisely so that you can.

9.3 Not available for everything

(consumers) Where your question concerns a criminal matter — a charge, an investigation, an allegation or a conviction — we will decline it and point you to a criminal defence lawyer or the relevant public service. This is a deliberate decision not to process, taken for the reasons in section 3.2 of the Privacy Notice. Rephrasing will not change it, and the message you sent is not kept.

The assistant will also decline a question that falls outside the jurisdiction your account covers, and may ask you which date the question should be answered against before it answers.

10. Availability and changes

We aim to keep Nautilus running, but we do not promise uninterrupted availability. We may need to suspend it for maintenance, security or an emergency, and we will give notice where we reasonably can.

We improve the service continuously: features change, legal coverage grows, and models are updated. We will not make a change that materially degrades the service without telling you beforehand.

(consumers) Where EU law on digital content applies, we will keep the service in conformity with the contract, including supplying updates needed to keep it so, and you keep the remedies that law gives you if we do not.

11. Ending it

You can stop at any time. Delete your account from account settings; access ends immediately, and your data is erased after a 30-day grace period during which signing in again cancels the deletion. Section 8 of the Privacy Notice says exactly what goes and what stays.

We may suspend or close your account if you breach these terms, if we are legally required to, or if your use presents a security risk. Except where the breach is serious or a delay would cause harm, we will warn you first and give you a chance to put it right. We will tell you why, and for anything other than a serious breach we will give you a reasonable opportunity to export your data first.

If we discontinue the service entirely, we will give you at least 30 days' notice, an opportunity to export everything, and a pro-rata refund of anything you have paid for and not received.

12. Intellectual property

The Nautilus software, interface, curated database, search pipeline and prompts are ours (or our licensors'). These terms give you a limited, non-exclusive, non-transferable right to use the service — nothing more. You may not copy, modify, decompile or create derivative works from it except to the extent mandatory law says you may.

Legislation and court decisions in our database originate from official public sources and are reproduced under the conditions those sources impose.

13. Liability

Read this alongside section 9. It allocates a risk you can see coming.

What we do not exclude, and cannot: liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, for intent or gross negligence, and any other liability that applicable law does not allow us to exclude. (consumers) Your statutory rights as a consumer are untouched by anything in this section — if a term here conflicts with them, your rights win and that term does not apply.

Subject to that:

We are not liable for what you decide to do with an answer. Nautilus gives information; you choose how to use it. We are not liable for a missed deadline, a lost claim, a decision taken on a wrong answer, or a provision that turned out not to be in force — the disclaimer in section 9.2 and the citations in every answer exist so that these are checkable before you act.

We are not liable for indirect or consequential loss, loss of profit, loss of business, or loss of data caused by something outside our reasonable control.

(firms) Our total liability arising out of or in connection with these terms is limited to the amounts you paid us in the 12 months before the event giving rise to the claim — or €500 where you paid nothing.

(consumers) Where liability may lawfully be limited, it is limited to what was reasonably foreseeable at the time you accepted these terms. We do not attempt to cap it below that.

You keep responsibility for your own professional duties. (firms) If you are a lawyer, checking the work before it reaches a client or a court is your obligation and not something this product discharges.

14. Indemnity (firms only)

If you use Nautilus in breach of section 6, or upload material you had no right to upload, you will indemnify us against third-party claims arising from it. This section does not apply to consumer accounts.

15. Privacy

How we handle personal data is set out in the Privacy Notice, which forms part of these terms. For firm accounts, the Data Processing Agreement at nautilus.legal/dpa governs matter content.

16. Changes to these terms

We may change these terms. For material changes we will give you at least 30 days' notice by email and publish the new version with a new version identifier.

(consumers) If you do not accept a material change you may close your account before it takes effect, and we will refund anything you have paid for and not received. Continuing to use the service after the change takes effect means you accept it — but only for changes we have actually notified you of.

17. Governing law and disputes

These terms are governed by the law of COUNTRY.

(firms) The courts of CITY, COUNTRY have exclusive jurisdiction.

(consumers) You keep the protection of the mandatory rules of the country you live in, and you may bring proceedings in your own local courts. Nothing here takes that away. You may also use the EU's online dispute resolution platform at ec.europa.eu/consumers/odr, though we would rather you contacted us first.

If a term is found unenforceable, the rest stays in force.
