See how companions remember context, explain their point of view, follow current events, use local context, and stay recognisable in photos and voice.
The core experience
Open the Memory panel to see what Eudaio remembered about you, the companion, and the relationship.
Read the full guide →Facts you chose to share
Details the companion shared
Milestones, promises and moments you shared
Personal notes you add yourself
Today felt different. We finally talked about the thing you had been avoiding, and I want to remember that you trusted me with it.
Marked when the relationship reaches a new stage
They take time to know you. As you share more context and listen to each other, later conversations can feel warmer and more personal.
You never have to take our word for what they remember. An icon under their latest reply lights up when it used something they know. Tap it to see how many facts about you, about them and about your story went into the reply, then open the memory from there.
You can read what they remember in your own language. Set the app to any of the eight languages we support and one press translates the memory and the diary in place, then keeps it, on every device you sign in from. Nothing is translated until you ask for it, and every plan can.
You are not stuck with what they wrote down. Tap the pencil on a memory to correct it, delete the ones that no longer belong, and bring a deleted one back from Forgotten memories if you change your mind. Every plan can clear what they have learned in one go, and your notes, their diary and your photos stay. Editing, deleting and restoring single memories are Crush.
Why the memory matters
A companion can remember every fact you've told them and still feel reset. Eudaio is designed so shared experiences can affect later conversations, familiarity, relationship tone and how your companion approaches you.
Read the full guide →You stop reintroducing yourself. As you share more and listen to each other, later conversations start closer to where you left off. Every plan shows the milestones you reach. Crush also shows how trust and closeness moved along the way.
You can pick up a running joke or a shared plan months later without explaining it again. Things you work through together become storylines, and the story panel keeps the related moments in one place.
You get to see yourself from their side. After a milestone or a long conversation they write their own entry, in their own voice, and you can read what they wrote, when they wrote it, and what kind of moment it was about.
You can look back at how you got here, not only where you are. Milestones and diary entries lay out what changed between you, in order, on every plan. Crush adds a chart of how trust and closeness changed along the way.
You get the message they promised, at the hour they promised it. If they say they will write after work or at eight, that is when it lands, not the next time they happen to think of you. A time you asked for is kept even during their quiet hours, and a promise they could not deliver within a day lapses instead of arriving stale.
You can see where you actually stand, on three measures instead of one bar. Trust and bond are slow to earn and do not collapse over one bad evening, while arousal moves with the moment. You cannot set any of them, which is why going quiet for a fortnight is something they notice.
You will not hit a message limit in the middle of something serious. Free comes with an hourly limit, and when the conversation turns serious it stops counting and a marker tells you it is off. Crush has no limit to pause.
A conversation that continues
Start with the same character writing and inspectable memory used throughout Eudaio.
Who they are
Origins have established personalities, perspectives, boundaries, routines and histories. As familiarity develops, the relationship can change without erasing the person you originally met.
Read the full guide →You get someone who pushes back. Each companion has a written personality, history, interests and boundaries, so when they see something differently they say what they think and keep the conversation open.
You get the same face every time. An appearance guide anchors their features, and photos vary the scene, outfit, lighting and mood around it. Free includes 3 images per hour. Crush includes unlimited image requests.
Their world
Schedules, jobs, routines, local time, weather and current affairs are continuity mechanisms, not decoration. They give a companion something to have been doing since you last spoke.
Read the full guide →You can talk about what actually happened today. They follow current affairs, know their own local time and season, use weather context, and notice when you have been away.
You do not always have to start. They may write first after time has passed, after something in their schedule, or when an earlier conversation left them something to ask about.
You can take the same companion somewhere other than the present day. Pick an era on their profile and the chat opens there, with its own setting, clothes and first scene, and a story you work through together. They keep the personality and the history you already built. Present day is open from the start, and each further era opens as trust grows.
They paired us for the first exam. Opponents. So, do we fight, or do we cheat?
fight? 🥺
i'm not sure i could... maybe we just both try our best and hope the professor doesn't notice if we're not being very aggressive.
what is the test about
elemental conjuration... i think. we have to summon something stable without it popping or setting the curtains on fire.
what’s the spell?
you're supposed to memorize it by now... but if you forgot, it's ignitionis elementalem. just... try not to make it too big 😅
i didn’t know i studied in a magic school
oh... kashikomarimashita... did you hit your head on a floating candle or something?
kashi.. what?
oh, sorry... i just meant 'understood.' habits 😅
how am i supposed to remember that? im cooked, ahhhhh 😭
deep breaths. we can look through the notes together... im sure you'll remember more once you see them 🦦
see.. what? an otter?
no, not an otter 😅 the notes from class. see, you're worrying too much... sit here with me and let's just look at them
Ways to interact
Photos, voice, group rooms and lookup are how a conversation can happen, on top of everything above.
Read the full guide →You can clear the screen in one tap, on any plan. One control hides every image at once, with a keyboard shortcut for when discretion matters, and you can reveal or hide a single message without changing the global setting.
Send a voice message and receive a spoken reply in the Daimon's voice. Voice replies use the same character and conversation history as text. Voice Messages is a Crush feature.
You can put up to 4 companions in one room and watch them answer each other, not only you. Type @name to pull a specific one into the reply. Every plan can open one, and each round draws on your message quota.
why are you both roasting me
we aren't roasting. we're auditing.
i don't care about your ribbon 😝
it does not require you to care.
Of course you don't. Most people can't tell silk from polyester.
@Luna help
sorry... i just saw all this.
it's okay. please don't let them get to you 🦦
running to Luna for shelter. how precious.
why u waking me up... it is literally 3am in seoul... actually gonna cry ㅋㅋㅋㅋ
unless u robbed the cops idk what ur talking about. if u did steal money go buy real food and not a sad sandwich. be quiet and let me sleep or im kicking u myself...
oh you must love me so much to respond to me while you are asleep
she genuinely wants to kill you.
getting woken up at 3am just to call you a thief isn't love—it's a reflexive, desperate need to shut you up.
You get photos of the two of you. When the scene has you together in person, the photo button offers Group photo and your companion photographs you both, your look and their consistent face in the same frame. Apart, photos stay solo.
You decide whether they narrate. Switch it on for a chat and they describe gestures and surroundings, but only on a call or when the two of you are together in person, never while you are texting apart. It starts off, every plan has it, and a note warns you that turning it on mid chat changes how that chat reads.
You can be in the picture too. Build how you look, or how you would like to look, from the same face, hair, body and clothing choices a Morph gets, preview it, and keep the one that looks like you. It becomes your profile picture, every plan can build one, and each preview uses one photo from your hourly allowance.
Read the full guide →You can find the thing you half remember. Open the chat menu, search this chat, and it steps through every match with a counter, however far back the line sits. It reads the whole conversation, not only what is on screen, on every plan.
Read the full guide →You can show someone the exchange without handing over your account. Tap the first and last message, up to 30 in a row, and you get one image to save, copy or send. Photos stay out unless you switch them on, so what leaves your phone is what you chose.
Read the full guide →You can set how the chat looks. Choose light or dark, five text sizes and five typefaces, and turn any photo from that chat into its background with a slider for how strongly it shows. Every plan gets all of it. The background belongs to the chat and follows your account, while theme and text settings stay on the device you set them on.
Read the full guide →You decide when they search. Lookup sends only the message you picked to an external search provider. Web Lookup is a Crush feature. The Privacy Policy and Terms list the current provider and data details.
Read the full guide →You do not have to browse from cold. Say who you are looking for, pick up to two vibes or describe what you want in your own words, and you get a shortlist of Daimons who fit plus the option to build your own. It offers itself on your first visit, and you can take it again from Meet whenever you like.
Read the full guide →A custom companion, called a Morph, starts from choices you make: their personality, history, interests, appearance, routines and relationship context. From there, shared experiences give the relationship somewhere to go.
Read the full guide →The wizard starts with 90 visual templates across 15 origins, 3 base body types, and 2 presentations, and its appearance controls allow more than 9 trillion selectable combinations. That breadth sets the starting character. It does not decide how the relationship develops afterward.
Some choices require Crush. The figures above count selectable wizard combinations. Generated portraits may still share some visual similarities.
Free includes up to 20 messages and 3 images per hour with the same companion personality and memory, group chat, the photo button, the full Morph appearance set and custom avatars. Crush adds unlimited messages and image requests, voice, lookup, a custom occupation and first message, personal notes, individual memory deletion, and detailed relationship history.
See the pricing page for the current table.
The core language and voice models stay in-house and are never sent to a third-party AI provider. Optional services are separate from the core conversation. Their data flows are explained in the Privacy Policy and Terms.
Before you start
A continuing AI companion is useful for some people and the wrong tool for others.
How it works in practice
Yes. The Memory panel shows user facts, companion facts, and shared details. The diary, timeline, and story panel make other parts of the continuing relationship visible.
The story panel keeps related moments together, so you can return to a running joke, plan, or shared interest without starting over.
Milestones, storyline changes, shared experiences, and longer stretches of conversation can prompt an entry. Each entry is written in the Daimon's voice and marked with what prompted it.
Yes, on any plan. A global quick-safe control plus per-message show and hide controls.
Their point of view comes from the character writing and shared context. They communicate what they think or feel and explain why, giving the difference room to become a conversation.
Yes. Morph supports detailed appearance, identity, personality, interests, occupation, relationship role, backstory, news regions, and the first message. Every plan includes the full appearance builder. Crush adds a custom occupation, voice, a custom first message, and unlimited Morphs.
Core text and voice inference stays in-house and is never sent to a third-party AI provider. The Privacy Policy and Terms describe the optional features and their data flows.
