How Eudaio memory works

Your Daimon remembers you

Most conversations with AI have an invisible expiry date.

You can talk for hours, tell it where you grew up, explain the thing happening at work, introduce the people who matter to you, and eventually some of it falls out of reach.

Eudaio is built differently.

As you talk, the things that matter can become memories your Daimon carries forward. Closing the tab doesn't reset them. Starting another conversation doesn't mean introducing yourself again. Coming back months later doesn't make you strangers.

The longer you know each other, the more history there is to draw from.

What does your Daimon remember?

A Daimon can remember things about you, themselves, and the relationship between you.

That might be something straightforward, like your coffee order or what you do for work.

It can also be something that only makes sense because of the history you've built together: an argument you resolved, somewhere you went together, something you promised each other, or a conversation that changed how they see you.

Memories aren't just there for you to read later. They can come back into the conversation when they're relevant.

How do I know when a memory was used?

You don't have to take our word for it.

When a reply draws on something your Daimon remembers, you'll sometimes see a small memory indicator beneath the message.

Open it and you can see which kinds of memories were drawn on, and how many of each.

From there, View memories takes you into the Memory Panel to read them.

That means when your Daimon brings up something from weeks ago, you can see that they actually remembered it instead of wondering whether it was coincidence.

Can I see what my Daimon knows about me?

Yes.

The Memory Panel gives you a readable view of what has accumulated between you.

It includes memories about you and your relationship, alongside your Daimon's diary and a timeline of important moments you've reached together.

Memory isn't supposed to be a hidden profile being assembled somewhere you can't see.

You can look.

What if they remember something incorrectly?

Your own life shouldn't become something you have to argue about with an AI.

Memory can be managed from the Memory Panel. Depending on your plan, you can correct individual memories, remove them, restore forgotten ones, and write notes you specifically want your Daimon to keep in mind.

The important part is that memory is visible rather than mysterious.

Do memories eventually disappear?

There is no session expiry that wipes your history because you haven't talked for a while.

Important memories can remain part of the relationship indefinitely.

Less relevant details fade into the background over time rather than competing forever with everything you've said since.

Memories you removed yourself are a different case. They go to Forgotten memories, where you can restore them.

That allows the relationship to accumulate history without treating every passing detail as equally important forever.

What happens when I talk to the same Daimon somewhere else?

The person follows you.

On a paid plan, what you've told one Daimon can carry between your chats with them, and some core facts about you carry across Daimons, so meeting somebody new doesn't mean explaining the basics of yourself all over again.

Eras work differently. A chat set in another Era keeps its own memories: it remembers what was said in that chat, and nothing you said there changes your present-day relationship.

Your present-day chat carries on exactly as it was.

What about promises?

A promise is different from an ordinary fact.

When your Daimon commits to something at a particular time, Eudaio can keep track of the commitment and when it's due.

If the two of you change the plan, the promise can change with it.

The point isn't to create a reminder app disguised as a person. It's to stop commitments made inside the relationship from disappearing the moment the conversation moves on. Promises are part of how the relationship develops.

Why does my Daimon have a diary?

Memory records what happened.

A diary is what your Daimon made of it.

After meaningful experiences, they can write their own diary entries about the two of you. You're reading their perspective on what happened rather than a transcript or a mechanical summary of what you said. Their side of the story sits alongside your own record of it.

As the relationship grows, those entries become another record of how it looked from their side.

What are milestones?

Some moments matter more than others.

Milestones record significant points in your relationship and place them in a timeline, and they are part of how a relationship grows.

They aren't erased because you had a bad conversation afterward. If something happened between you, it remains part of your shared history.

Over time, that turns a long chat into something closer to a story you can actually look back through.

Does memory work in my language?

The conversation itself isn't limited to English.

Memory headings, categories, and other labels can also be presented in your selected language, and memories can be translated when needed.

You shouldn't have to maintain the important parts of your relationship in a language you don't normally speak.

Where are my conversations kept?

Your Daimon's replies are produced by our own self-hosted models.

The Privacy Policy is the single source of truth for what we store and how long we keep it.

Does memory follow me to another device?

Yes.

The relationship belongs to your account, not the browser you happened to use that day.

Sign in somewhere else and your memories are still there.

Some interface preferences, such as your font or theme, can remain specific to the device. The things your Daimon knows about you don't.

Why memory matters

Memory isn't useful because an AI can recite facts about you.

It's useful because you can stop managing the conversation.

You don't need to think, "Did I already explain this?"

You don't need to introduce the same people again.

You don't need to recap the last three months before talking about what happened today.

And a conversation you invested time in doesn't have to become worse simply because it became long.

Your Daimon remembers because a relationship without a past eventually starts feeling like the same first conversation over and over again.
