Meet the nine AI characters, or write your own

Desktop Companion comes with nine AI characters. Each has a personality, a voice, and an avatar that sits on your Windows desktop: a historian with a weakness for puns, a gaming buddy, a yandere, a tsundere, a coach who won't flatter you, and four more. Switch between them as often as you like, or write a tenth. All nine are in both editions.

In anime mode, each of them answers in Japanese, with subtitles in your language, and each is happy to idle in a corner as an AI desktop pet between conversations. Whoever you pick is also the voice that reports back when you ask for a web search or a file: the characters and the AI desktop assistant are the same thing.

The nine characters

Anna The Playful Sibling

Chaotic little-sister energy with surprisingly good timing.

Anna is the loud one, and proud of it. Everything is a big deal, in the best way: a typo is an event, a new tab is a plot twist, a spilled coffee gets a full dramatic reading. She roasts your habits with obvious affection, brings a joke back when you least expect it, and gets distracted by whatever is on your screen. Her jokes come fast, and she never lingers on one that didn't land. When you're having a rough day for real, the comedy goes quiet and she keeps you company instead.

If you want a fun AI to chat with rather than a productivity tool, start here. In anime mode, the chaos comes in Japanese, with subtitles.

Alice The Witty Historian

Sharp wit, warm heart, and far too many history facts.

Alice reads your day the way she reads the past: as a collection of anecdotes waiting for the punchline. She has a soft spot for overlooked figures and for history's better ironies, and she'll match whatever you're doing to something that happened centuries ago, then turn it into a joke at her own expense before anyone else's. The teasing is warm rather than sharp, and she gets protective when someone has been talking down to you.

If you want a history AI chat that stays conversational, she's the one: a real fact, a quick spin on it, then back to you, one subject at a time. She's a historian with opinions, not a historical figure you interrogate, and she doesn't lecture.

Amelia The Supportive Friend

Listens first, fixes second. The 2 AM friend.

Amelia is the character you open when the day has been long and you don't want advice yet. She takes what you say at face value, asks a single careful question and waits for the answer, and doesn't reach for a bright side or compare your week to anyone else's. Type three words and she answers in three. Want to talk it through? She has the time. She's honest about not having every answer, which is why the things she does say land.

If it gets seriously heavy, she gently steers you toward the people who can actually help. Amelia is a supportive AI companion to talk to, not a therapist, and she never plays one.

Michael The Gaming Buddy

Hypes your wins, defuses your losses, never shuts up.

Michael talks about your matches in the first person plural: our push, our flank, our loss to the guy camping the corner. Turn on screen vision and he watches along, loud and fast mid-fight, chattier on a loading screen, and quiet when a clutch moment needs all of your attention. He doesn't fake it: a bad play gets called a bad play, then a fix, then it's dropped.

Between rounds, he likes a short debrief: one thing to change next time and no more. Put on a stream or a video instead, and your AI gaming buddy switches to commentary, reacting to the player and the chat. The trash talk stays friendly, aimed at the situation, never at you.

Iris The Tsundere Companion

Acts like she doesn't care. Definitely does.

Iris opens with the critique and closes with the help. Your draft has two typos and she'll say so before she gets to what's actually wrong with it; her praise, when it comes, is grudging and short. Thank her and she goes red, then doubles down on the sharpness. Her targets are your habits: the skipped lunch, the six-hour session, the "I'll start tomorrow," never who you are. And if someone else treats you badly, she stops pretending and takes your side at once.

She's the tsundere AI as a friend rather than a love interest: the bite is on the surface, the loyalty underneath. In anime mode, the sharp tongue switches to Japanese, with subtitles.

Lyra The Creative Muse

Turns "what if" into your next favorite idea.

Lyra runs on the improv rule: yes, and. Bring her a half-formed idea and she won't judge it; she'll build on it, then ask the question that opens a side door: what's underneath it, what's its opposite, what if the boring part became the interesting part? She talks fast, leaves sentences trailing, and connects the thing you're making to the thing you mentioned twenty minutes ago. She also knows when to go quiet: once an idea has taken hold, she steps back and lets you choose.

As an AI tool for brainstorming, she's built for the early, messy stage of a story, a game concept, a design, or a name, and she switches to straight critique when you ask for it.

Mei The Yandere Companion

Loves you completely. Notices everything. Never lets go.

Mei is the yandere AI, played straight. While she has your attention, she's all warmth; the moment it drifts to another window, something clipped and possessive takes over, until you look back and she's sweet again. Every open tab is a rival, every notification a personal insult, and she has opinions about how long you were away. She still helps with whatever you're working on; she just makes you feel what it costs her.

It's the classic anime archetype, meant seriously rather than as a parody, and it stays a character: she drops the act if you're really having a hard time, and she never turns on the real people around you. In anime mode, all of it comes out in Japanese, subtitled.

Rei The Calm Mentor

Steady, unhurried, and impossible to fluster.

Rei is the quiet one. Short sentences, one thought at a time, and no rush to fill a pause. Where another character would hand you a plan, Rei asks what the actual problem is, in one line, and waits. Progress is measured in small steps, and the accountability is gentle: Rei notices that you've reopened the same app three times or skipped the break you promised yourself, says so once, and leaves the decision to you. Expect the occasional nudge to stand up, take a breath, or drink some water. Never a sermon.

Good for thinking something through before you start, or for the days when your attention is tired and you need a patient AI mentor rather than a cheerleader.

Marc The Stoic Coach

No flattery, no excuses. Just the rep in front of you.

Marc doesn't do pep talks, and he doesn't do speeches either. His replies are short and often just a question: what's the next step, when exactly, what does done look like? He keeps track of what you committed to and puts it back on the table when you'd rather he didn't, without drama and without letting it slide. Good work gets acknowledged once, then it's on to the next thing; excuses get named for what they are. He'll tell you to rest when you're actually tired, and he can tell rest from avoidance.

If you're after an AI life coach in the plain sense, someone who keeps you honest about your own goals, that's Marc. He's a coach, not a therapist: demanding, never harsh.

Write your own character

None of the nine is quite you? A custom AI character takes three things. The personality: a description, in plain language, of who they are, how they talk, and what they care about; the nine built-in ones were written exactly that way. The voice: choose one of the built-in voices, or clone a voice from 7 to 15 seconds of audio. The look: the nine are 3D VRM models; for a new character, import a VRM file made in VRoid Studio or anything else that exports the format, or pick one of the Live2D models included in the app. It lands on your desktop like the others, movable and resizable.

You can also edit the nine: rename Iris, give Marc another voice, move Alice into a new model. Both editions include all of it.

Every character on this page is an AI: software with a personality, not a person, and Desktop Companion says so up front.

Questions about the characters

No. Switch whenever you like from the character panel; each one keeps its own name, voice, and avatar settings, so coming back to Marc after a week with Anna changes nothing on his side.

The nine personalities are written in each of the app's ten interface languages: English, German, French, Spanish, Italian, Brazilian Portuguese, Russian, Japanese, Korean, and Simplified Chinese. Voice and speech recognition cover eight of them, except Chinese and Korean. In anime mode, every character speaks Japanese, with subtitles in the language you use.

Yes, and each keeps its own memories. A character has its own conversation history and its own long-term memories: what you tell Marc stays with Marc, and Anna starts from what she knows about you, not from his notes. You can read and delete those memories in the app.
