What should you tell an AI companion in your first week with her?
Your first week sets what an AI companion remembers about you. A day-by-day plan for what to share, what to keep to yourself, and how to check what she has learned.

Short answer: In your first week, tell an AI companion what to call you, why you are using her, your daily rhythm, your interests, a goal you are working on, and how you like to be talked to. Never share passwords, codes, financial account numbers, or ID numbers. At the end of the week, ask her what she has learned and correct anything that is wrong.
The product details in this article come from the Lumina AI Companion page and the Lumina: AI Companion listing on Google Play.
Why does the first week matter so much?
A companion with persistent memory builds on what you tell her. Lumina AI Companion keeps memory across conversations, so she does not start from zero each time, and early details become the foundation for later ones. A few clear facts in week one go further than a long list on day one. For how that memory works in general, read our pillar guide, How AI memory works in companion apps.
What is a good seven-day plan?
One small topic per day keeps it natural:
- Day 1: who you are and why you are here. What you want to be called, and what you hope to use her for: thinking things through, staying organized, learning something, or simply company.
- Day 2: your daily rhythm. When you usually wake, work or study, and wind down. It helps her suggest things at sensible times of day.
- Day 3: what you love. Two or three interests, such as a hobby, a team, a genre, or a place.
- Day 4: a goal you are working on. Something concrete, like finishing a course, a project, or a habit you are building.
- Day 5: how you like to talk. Short or detailed answers, playful or straight to the point, questions or suggestions.
- Day 6: something worth remembering. A date, a person's name, or a milestone that matters to you.
- Day 7: check what she has learned. Ask her what she knows about you, and correct anything that is off.
You do not need to follow this to the letter. The point is steady, specific context, a little at a time.
What should you never share?
These stay out of every chat app, companion or not:
- Passwords and one-time sign-in codes
- Full bank, card, or account numbers
- Government ID numbers, such as a Social Security number
- Other people's private details they have not agreed to share
A companion does not need any of these to know you. For a wider view of keeping a companion in its place, see How to set healthy boundaries with an AI companion.
How can you check what she remembers?
Ask her directly, for example: "What do you know about me so far?" Then correct anything wrong in plain words. In Lumina, you can also open the Living Neural Map, which shows what she has learned as a visual knowledge graph you can explore. Over the following weeks she keeps adapting, which we explain in How do AI companions adapt to your personality?
What do we know, and what is still open?
What is true for Lumina: memory persists across conversations and is private to each user, and the Living Neural Map shows what she has learned.
What depends on you: how much you share and how quickly. There is no right amount. Share what you are comfortable with, and remember that you can correct her at any time.

Frequently asked questions
What should I tell an AI companion first?
Start with what you want to be called, what you hope to use her for, and two or three things that matter to you right now, such as a goal, a project, or an interest. That gives her enough context to be useful from the first conversation.
What should I never tell an AI companion?
Never share passwords, one-time codes, full bank or card numbers, or government ID numbers with any chat app. A companion does not need them to know you.
How do I know what my AI companion remembers?
Ask her directly what she knows about you, and correct anything that is wrong. In Lumina AI Companion, you can also open the Living Neural Map to see what she has learned as a visual knowledge graph.
