Terms of Service

1. Provider and scope

nexcite is provided by BlockBite GmbH, c/o Mathias Scherer, Hardstrasse 59, 5432 Neuenhof, Switzerland. These Terms apply to the website, application, registered accounts, uploads, web sources, AI features, feedback and support.

During the closed beta, nexcite is intended for students and private individuals only (B2C). Use by institutions, companies or other organisations requires a separate written agreement.

Deviating terms of users apply only if nexcite expressly agrees to them in writing.

2. Beta programme

nexcite is operated as a beta service. Features may change, be restricted, interrupted or removed. Beta access may be granted through a waitlist, invitation or approval process.

The beta status is disclosed because availability, support processes, pricing, feature stability and deletion processes may differ from a mature production service. This does not limit mandatory consumer, data protection, confidentiality or security obligations. nexcite may use feedback, error reports and usage information to improve the service, understand demand and develop a fair pricing model before launch.

3. Account, access and security

Users must provide accurate and current account information. They are responsible for keeping their credentials confidential and must inform nexcite if they suspect unauthorised use.

nexcite may require two-factor authentication, e-mail verification, approval processes or other security measures. Accounts may be suspended where required for security, abuse prevention or legal reasons.

4. Acceptable use

nexcite may be used only lawfully, carefully and within the provided functionality. In particular, the following is prohibited:

• unlawful, abusive or deceptive use,
• uploading or processing content without the required rights or legal basis,
• attempts to circumvent security mechanisms, access controls or rate limits,
• automated scraping, reverse engineering or overloading the systems,
• misrepresenting AI-generated or AI-assisted work as the user's own independent work, bypassing academic integrity rules or violating plagiarism, examination, citation or institutional AI-use policies,
• use for high-risk decisions, in particular in medicine, law, credit, employment, government decisions or critical infrastructure, unless separately agreed in writing.

5. User content and rights

Users retain their rights in uploaded documents, web sources, prompts, chat histories and other content. They grant nexcite a limited, non-exclusive and purpose-bound licence to host, analyse, index, process and transmit such content to integrated service providers where this is necessary to provide nexcite.

Users represent that they have all required rights, permissions and legal bases. This applies in particular to personal data, confidential information, copyrighted works and sensitive data. Users remain responsible for checking whether third-party materials such as lecture slides, academic papers, books, excerpts or shared course materials may be uploaded and processed in nexcite.

6. AI outputs, citations and review obligation

nexcite uses a RAG-LLM pipeline to generate answers from provided sources and link them to source references. Despite source-based processing, errors, incomplete answers, incorrect weighting or misleading wording may occur.

Users must review all outputs, citations, source references, conclusions and bibliographic information before using them. nexcite does not replace professional legal, medical, tax, financial, audit or academic integrity advice.

nexcite is not an academic integrity, plagiarism detection or institutional compliance tool. Users are responsible for complying with their school, university, publisher, employer or examination rules on plagiarism, citation, collaboration and AI-assisted work.

Statements about accuracy or reliability apply only in the context of the documented technical quality assurance and do not constitute a guarantee of completeness, freedom from errors or fitness for a particular purpose.

7. Web sources and third-party content

Where users add URLs or web sources, they are responsible for ensuring that retrieval, processing and further use are lawful. nexcite may use external services for web search or extraction and is not responsible for the availability, accuracy or legality of third-party content.

8. Privacy and processing

The processing of personal data is described in the Privacy Statement. For the closed beta, nexcite is currently offered to students and private individuals only. If nexcite is later offered to institutions, companies or other organisations, additional data processing terms may be required.

9. Availability and changes

nexcite strives to operate reliably, but while the service is operated as a beta it does not owe any specific availability, response time or continuity of features. Maintenance, security measures, technical incidents or changes at service providers may cause interruptions.

nexcite may change features, models, limits, interfaces and user interfaces where this is required for operation, security, product development, legal reasons or economic viability.

10. Feedback and usage insights

nexcite may use feedback, suggestions, bug reports, ideas and aggregated usage insights without compensation to improve the product, documentation, security, quality and future pricing model. Rights in confidential user content remain unaffected.

11. Pricing and payment

During the closed beta, nexcite is free of charge for all approved beta users. No payment details are required, and beta access will not automatically convert into a paid subscription.

Before any paid plan is introduced, prices, scope of services, payment terms, contract periods and termination periods will be communicated separately and will require explicit acceptance. Where consumer pricing is displayed, nexcite will indicate prices clearly and without misleading statements, including applicable taxes, non-optional charges and the relevant currency where required.

12. Term, termination and deletion

Users may end their account or access using the available features or by request. nexcite may terminate or suspend access where these Terms are breached, security risks exist, the programme ends or legal reasons require this.

Data deletion is governed by the Privacy Statement. We store personal data only as long as necessary for the intended purpose. Users can request deletion of their data at any time through the privacy contact address or through the data subject rights described in Privacy Statement Section 9.

13. Intellectual property

nexcite, the software, user interface, documentation, trademarks, logos and product concepts remain the property of nexcite or the relevant rights holders. Users receive only the revocable, non-transferable right of use required to use the service.

14. Liability

nexcite is liable in accordance with mandatory law. To the extent permitted by law, liability for slight negligence, indirect damages, consequential damages, data loss, production downtime, loss of profit and damages arising from erroneous or unreviewed AI outputs is excluded.

Nothing in these Terms limits liability that cannot be excluded or limited under applicable mandatory law.

15. Changes to these Terms

nexcite may amend these Terms if the product, beta programme, legal requirements, service providers or business model change. Each version is identified by version number and date. Where the application requests acceptance, the acceptance record should include the applicable version and date. Material changes will be communicated in an appropriate form.

Where changes materially affect contractual rights, fees, data processing expectations or other consent-relevant terms, nexcite will request explicit re-acceptance through the account flow or another suitable mechanism. Continued use after the effective date may be treated as acceptance only to the extent legally permissible and only where explicit acceptance is not required.

16. Governing law and jurisdiction

Swiss law applies, excluding conflict-of-law rules. The place of jurisdiction is Zürich, Switzerland, unless mandatory consumer or data protection rules provide for another jurisdiction.
