Terms of service
Know Nota provides Nota, an AI-text detector, with free and paid plans. These terms set out what you can expect, what it does not promise, and the rules for using it.
1. Who provides this service
Know Nota (“the Service”) is operated by ROGA AI LIMITED, a company registered in Gibraltar under number 125994, with its registered office at Unit G02, Eurocity, Europort Avenue, Gibraltar, GX11 1AA (“we”, “us”, “our”). Contact: legal@rogaai.com.
2. Accepting these terms
By using the Service, including the web interface and the API, you agree to these terms. If you use the Service for an organisation, you confirm you are authorised to accept them on its behalf. You must be at least 18, or the age of majority where you live.
3. Plans, payment and quotas
The Free plan costs nothing and requires no card. Paid plans are billed in advance, monthly or annually, through our payment processor (Stripe); prices, word quotas and features are those shown on the pricing page at the time of purchase and may change for future periods with notice. Quotas are measured in words rounded up to the nearest 100 per scan; scans the detector abstains from are not charged. Unused quota does not roll over. You may cancel at any time and keep access until the end of the paid period; refunds are given where the law requires them, and otherwise at our discretion. Where a plan states an availability commitment it is set out on the pricing page; the Free plan carries none. We may apply rate limits or other restrictions to keep the Service usable for everyone.
4. What the Service actually does, and what it does not
This section matters more than the rest, so it is written plainly.
The Service reports how machine-like a passage of text looks under a named statistical model (Nota), together with the false-positive rate measured for that model on held-out human writing, and optionally a panel of writing statistics.
Do not rely on the Service for any of the following.
- A determination that text was written by AI, or by a person. Detector output is a probability with a measured error rate. It cannot name a generator, it abstains below 250 words, and a low score means only that this model did not flag the text. Treating any output as evidence of academic dishonesty, fabrication or misconduct against an individual is outside what the Service supports, and you accept sole responsibility for doing so.
- Sentence-level or “which model” findings. The Service scores whole documents and does not name generators.
- Regulatory compliance. Nothing in the Service is legal advice or a compliance determination. Using it does not make you compliant with the EU AI Act or any other law. Obligations such as Article 50(2) of Regulation (EU) 2024/1689 fall on the provider of the generative system and cannot be discharged by a third-party tool. Nota Records record what Nota observed in the bytes submitted at the time stated, and nothing more.
5. Your content
You keep all rights in the text you submit. You grant us only the limited permission needed to process it and return a result. Text submitted for detection is processed in memory and discarded unless you choose to keep it: a signed-in scan keeps its signed Nota Record — the SHA-256 of the text, word count, band, probability, model version, the character check, and the source check when run — and the text itself only when you switched on “keep the document in my record” for that scan. Batch jobs hold their input only until the job completes. Usage counters record the endpoint, the day, call counts and timing, and nothing about the content of requests. You are responsible for having the right to submit whatever you submit.
6. Accounts and API keys
Accounts are optional for a first look and required to hold a quota or a paid plan. Keep your credentials secure. An API key is shown once and is your responsibility from that moment; you are accountable for activity under your account or key. Tell us promptly at legal@rogaai.com if you believe either has been compromised.
7. Acceptable use
Do not use the Service to: break the law or infringe anyone’s rights; submit material you have no right to process, or personal data in breach of data protection law; attack, overload, probe or circumvent the Service, its quotas, rate limits or authentication; resell detect capacity without agreement; or present output as a compliance certification, an official approval, or forensic evidence. We may suspend or remove access where we reasonably believe these rules have been broken.
8. Intellectual property
The Service, its interface, documentation, models and branding remain ours or our licensors’. These terms grant you no rights in them beyond using the Service as intended.
9. No warranty
The Service is provided “as is” and “as available”, without warranty of any kind, whether express, implied or statutory, to the fullest extent the law allows. We do not warrant that it will be uninterrupted, secure, error-free, or fit for any particular purpose, nor that any detector output is correct in any given case.
10. Limitation of liability
To the fullest extent permitted by law, we are not liable for any indirect, incidental, special, consequential or punitive damages, nor for loss of profits, revenue, data, goodwill or business, arising from or connected to your use of the Service. Our total aggregate liability to you for all claims is limited to the greater of the fees you paid us in the twelve months before the claim arose and one hundred pounds sterling (£100). Nothing in these terms limits liability that cannot lawfully be limited. If you are a consumer, these terms do not affect your statutory rights.
11. Indemnity
You agree to indemnify and hold us harmless against claims, losses and reasonable costs arising from your use of the Service, your content, or your breach of these terms — in particular any claim arising from how you characterised or relied upon the Service’s output.
12. Suspension, termination and changes
You may stop using the Service at any time and may delete your account. We may suspend or terminate access where these terms are broken, or discontinue features with reasonable notice to paying customers. Sections 4, 9, 10 and 11 survive termination. We may update these terms; the effective date will change and material changes will be signalled in the interface or by email to account holders.
13. Governing law and contact
These terms are governed by the laws of Gibraltar, and the courts of Gibraltar have exclusive jurisdiction, except where mandatory law in your country of residence gives you the right to bring proceedings elsewhere.
