Our use of artificial intelligence
Last updated: November 11, 2026
We believe you have the right to know when artificial intelligence helps make what you read. Here is how we use it.
In our journals and articles
We use artificial intelligence tools, including Claude by Anthropic, to help us write, translate and lay out our journals and articles. Every journal is designed, chosen and reviewed by Lantern Days before it is published.
In Weekly Light
Your weekly letters and your monthly challenge are written by Claude, by Anthropic, from your form answers and your previous letters. They are checked automatically before sending, but are not reviewed one by one by a person. Every letter says so at the end.
Your information and AI
- Only what is needed to write your letter is sent to Anthropic (your first name, your answers, your challenge), never your email or payment information.
- Under Anthropic's commercial terms, data sent through its business service is not used to train its models.
- The AI makes no decisions about you: it only writes letters.
Its limits
The AI does not know you the way a friend or a professional would, and it can make mistakes. It makes no diagnosis and does not replace help from a professional. If you are not feeling well, turn to someone you trust or a help resource.
Lantern Days creates journals, guides, books and digital products for reflection and wellbeing. We are not health, mental health, legal or financial professionals. Our products, articles, emails and Weekly Light letters are not therapy, make no diagnosis and never replace help from a professional. We do not monitor messages in real time and cannot intervene in a crisis.
