An AI that remembers,
what does it change?

Persistent memory is the ability of an artificial intelligence to retain what you told it from one conversation to the next, rather than forgetting everything when you close the app.

How it works

Without memory, an AI only sees the current conversation. With persistent memory, it keeps what matters: your sister's name, an interview on Thursday, something weighing on you. It brings these back at the right moment, without you having to explain it all again.

Why it matters for wellbeing

Feeling heard also means feeling that the other remembers. Repeating your story each time is tiring and stops you going further. An AI that remembers can pick up the thread, notice what keeps coming back, and ask how the thing that worried you turned out.

Questions to ask an app

• Can I see what it has retained about me?
• Can I correct or delete it?
• Are my conversations sold or used for advertising?
• Is memory included in the free plan?

How Luxia uses it

Luxia builds a memory of your conversations, which you can view and correct at any time. The free plan keeps the essentials, Basic makes memory permanent, and Premium offers her deepest memory. On Premium, Luxia also uses it to write to you first: an interview on Thursday, she encourages you that day, then asks how it went.

Other apps are developing their memory too. To compare them, see our 7 criteria for choosing an AI companion.

A limit to keep in mind

An AI that remembers is not a person, nor a therapist. It can accompany your daily life, not replace a professional or the people who love you.
