Acceptance of Terms
By accessing or using Lenz (“we”, “us”, or “our”) at lenz.io, you agree to be bound by these Terms of Use. If you do not agree to these terms, please do not use the service.
Description of Service
Lenz is a fact-checking service that uses AI (specifically, multiple large language models) to analyse claims. The results are generated automatically and are intended for informational purposes only. They do not constitute professional, legal, medical, financial, or any other form of expert advice. You should always exercise your own critical thinking and consult qualified professionals where appropriate.
Account Registration
To use certain features of the service you may need to create an account. You agree to provide accurate and complete information during registration and to keep your account credentials secure. You are responsible for all activity that occurs under your account. You must notify us immediately if you suspect any unauthorised use of your account.
Acceptable Use
You agree not to:
- Use the service for any unlawful purpose or in violation of any applicable laws or regulations
- Submit content that is defamatory, obscene, threatening, or otherwise objectionable
- Use automated scripts, bots, or scraping tools to access or extract data from the service without our prior written consent
- Misrepresent AI-generated results as your own original analysis or as professional advice
- Attempt to interfere with, disrupt, or compromise the integrity or security of the service
- Circumvent any rate limits, access controls, or other technical measures we implement
Intellectual Property
The service, including its design, software, branding, and all AI-generated analysis content, is owned by Lenz and protected by applicable intellectual property laws. You retain ownership of the claim text you submit. By submitting a claim, you grant us a non-exclusive licence to process, analyse, and display the claim and its results as part of the service. If you choose to add a claim result to the Library, you grant us permission to make the claim text and analysis publicly available in anonymised form.
Editorial Policy
The Library is curated entirely by our editorial team. Editors decide, at their sole discretion, which claim analyses to add to the Library. Users cannot submit or contribute claims to the Library directly. When a claim has been reviewed and verified by a human editor, it is clearly marked as such on the claim page. Human-verified claims have been independently checked by our editorial team to confirm the accuracy and quality of the AI-generated analysis. The presence or absence of a human-verification mark is not a guarantee of accuracy. Human verification indicates that an editor has reviewed the analysis, not that the conclusion is correct. Lenz and its editors accept no liability for any errors, omissions, or consequences arising from reliance on any claim analysis, whether human-verified or not.
AI-generated claim analysis reports are never editorially modified. The results you see are produced entirely by our automated pipeline and are published exactly as generated. Every claim page provides full transparency: you have access to all sources consulted, the reasoning, methodology and AI models used, and the key output of each model involved in the analysis, so you can independently verify any conclusion. Our editors reserve the right to delete any claim analysis at their discretion — for example, in cases where technical issues are detected during the generation process that may have compromised the quality or integrity of the report. Claims are never edited, only deleted.
Subscriptions & Payments
Some features of the service require a paid subscription. Payments are processed by Stripe. By subscribing, you agree to pay the applicable fees and authorise us to charge your chosen payment method on a recurring basis. You may cancel your subscription at any time; cancellation takes effect at the end of the current billing period.
Disclaimer of Warranties
The service is provided on an “as is” and “as available” basis without warranties of any kind, whether express or implied. We do not warrant that the AI-generated results are accurate, complete, reliable, or error-free. Fact-check analyses are produced by automated systems and may contain mistakes or omissions. You acknowledge that reliance on any results is at your own risk.
Limitation of Liability
To the fullest extent permitted by law, Lenz and its operators shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising out of or related to your use of the service. This includes, without limitation, damages resulting from decisions made based on AI-generated results, loss of data, or service interruptions. Our total liability for any claim shall not exceed the amount you paid us in the twelve months preceding the claim.
Termination
We reserve the right to suspend or terminate your account and access to the service at our sole discretion, with or without notice, for conduct that we believe violates these Terms of Use or is harmful to other users, us, or third parties. Upon termination, your right to use the service ceases immediately.
Changes to These Terms
We may update these Terms of Use from time to time. We will notify users of significant changes by posting a notice on the site. Continued use of the service after changes are posted constitutes acceptance of the revised terms.
Governing Law
These Terms of Use shall be governed by and construed in accordance with applicable law. Any disputes arising from or relating to these terms or your use of the service shall be resolved in the courts of competent jurisdiction.
