Capri, the Project Capricorn construct from Cyberpunk: Edgerunners season 2, lives on your desktop and tells you what your coding AI is up to: Claude Code, Codex or Antigravity. She teleports, glitches, comments on every action, comes to find you when it needs your permission, and loses it when the job is done.

• When she starts: she grabs your screen. Its edges crackle red, her left hand slams onto its edge, then her right, her arms reach in along them as she hauls herself up, and her face hits the glass (a white flash, an ink one, her colours apart, the screen shaking). She looks around, blinks, opens her mouth wide on "hi" (a tag pops by her face, her name typed under it), lets go of the right edge to wave at you with her clawed hand, grabs it again, glances at where she's going, and lets go: her arms break into shards from her hands in, and her head crouches and dives down to her spot, where her body unfolds from her face.

  

• While Claude works: a ticker over her head shows the current action (EDITS gigs.ts, RUNS npm test, GREPS "paginate"…) and she sheds little data glyphs. When Claude runs a command or goes on the web, red sparks fly off her fingers; sitting on a window, she jacks into it and the lightning runs along its edge.

• When Claude goes quiet mid-task (thinking it over, or a slow local model): after 15 seconds the ticker turns violet and counts the seconds (THINKING… 45 s), and she keeps herself busy (a spin, a look around, the satellite once). After 40 seconds she says something about it; after two minutes she tells you nothing's stuck.

• When Claude needs you (permission, question): she teleports next to your mouse, mane bristling, and won't let it go. If you're on another window, she goes to Claude's window instead and points at it with her finger (a dashed line, brackets on its corners, CLAUDE on a tag): that's where the question is. She stops once you've answered.

• When a command fails: red impact frame, she gets knocked back, heavy glitch, and the error line that actually matters.

• When it's done: she teleports to the middle of the screen and goes into her victory sequence: a wind-up with her mane pulled in, a stretched smear frame, then arms flung up and mane exploding under manga speed lines and a shockwave, a manic laugh with an anime cut-in of her grin. Once she's back down, the summary (12 actions · 3 files changed · 2m 14s) and Claude's last sentence.

• When Claude answers and you're on another window: she shows you its whole answer, in a wider panel that scrolls (paragraphs, lists and code kept). It goes away when you're back on Claude's window, or when you click it. Claude's window is the one you typed your prompt in. Windows only, like the window tracking.

• The rest of the time: she floats, her mane sways and sheds shards, she drifts from one corner to another, turns around and cocks her head when your mouse comes near (or, little menace, zaps it with red lightning and a sly grin), looks up at the satellite, and falls asleep after 10 quiet minutes.

• When she sleeps: she dozes a while, then her mane and her body come apart and all that's left is what she is at heart in the show, her green mask and her eyes, floating where she was, eyes shut. Now and then she cracks one open. Bring your mouse close (or let Claude start again) and her blue eyes snap open and she comes back together around it.

• The satellite: the big sequence, kept for moments that matter. The first time of the day, a little while after Claude finishes a long job (8 minutes or more, or 50 actions), or whenever you like from the tray menu. The white specks of her mane lift off as a constellation, line up into a road from her fingers to the satellite, she coils up, and the red light goes up to it. It answers her, twinkling twice.

• She sits on your windows: perched on the top edge of a window, legs dangling and kicking one after the other. She rides along when you move the window, and falls off when you close, minimize or cover it. While Claude works she settles on the window in front if she can.
• She peeks in from the edges of the screen: half hidden on the left or right, or hanging upside down from the top. She's shy: get your mouse close and she ducks away to another edge.
• She falls: stretched, mane blown up, accelerating, then a big squash and a shower of shards when she lands. On the way down, a window ledge can catch her.
• Drop her on a window: drag her and let go with her hips on a window's top edge, she sits there. Let go anywhere else and she falls.
• She possesses your windows, like in the show where she slips into bodies and systems: now and then she dives into the window she's sitting on. Red lightning races round its frame, slices of it glitch, and the window looks at you with her eyes and her zigzag grin, more eyes opening all over it, every pupil on your pointer, and she laughs. Then she comes out of another window. Nothing is drawn over the windows in front of it, and the window's contents are never read: it's just drawn over, for two seconds. If it bothers you, untick Possess my windows in the tray menu.
• Little flourishes: a full spin with afterimages, a hop, looking left and right, the cocked head, and the other minds in her (her green and red copies) pulling away from her, hanging there, and snapping back in.

Window tracking is Windows-only for now (a tiny PowerShell helper reads window positions, no titles, no contents). On macOS and Linux she still floats, peeks, falls and wanders.

How does it work? in her menu: she asks what to show you, then takes you there and points at it. Her head snaps to it, she coils up leaning away, then strikes: her construct arm shoots out at it to twice its length, red lightning off her fingertip, a reticle slams onto it with two of her eyes opening on its corners, and a close-up of her eyes cuts in. Then she holds it while she explains, a wire of data running from her finger to it: now and then she jabs at it, or glances back at you. When she's done, the wire reels back into her finger and the arm snaps back.

• Where's my icon? She goes down by the clock and points at her tray icon, or at the ^ when Windows hides it.
• Where's Claude? She points at Claude's window: the one you typed your last prompt in.
• Claude's folder: she opens ~/.claude in Explorer with settings.json selected, points at the window, and explains what her hook in there is and how to take it out.
• Plug me into Claude: her hooks in one click. It's also her welcome the first time she starts. Next to it, Free with Ollama runs Claude Code (or Codex) through Ollama for you: her hooks go in, Ollama gets installed if it isn't, and a window opens on ollama launch claude, where you pick a model.
• Talk to me: see "Talk to her" below.

She pulls faces while she talks: eight expressions, all frames of her from the show (watching, turned away, the fang grin, eyes gone round, looking right at you, laughing with her mouth wide open, all her eyes at once, the zigzag grin). Each message picks the one that fits, and her portrait glitches from one face to the next.

Mission report in her menu: a card of what Claude got through today, made to be screenshotted. Tasks finished in big, then actions, files changed and errors, the longest mission and its project, prompts, approvals and projects. The numbers count up. Copy image puts a picture of the card on your clipboard, on its own dark plate, ready to paste anywhere. In the evening (after 6 pm), after a real day's work (3 tasks or more), she brings it to you once, on her own. The demo doesn't count, and it stays on your PC, one day at a time.

Talk to her in her menu (or the Talk to me button when you click her and nothing's going on): you type in her panel and she answers in character. She knows what Claude is doing and what it got done today. She answers in writing, in her own language. Enter sends, Esc closes.

The first time, she sets it up with you, with buttons, no terminal:

• On my PC (free, nothing leaves your machine): she installs Ollama for you (with winget, Windows' own installer), wakes it up, and downloads a model while a bar fills up: gemma3 (3.3 GB, better in languages other than English) or llama3.2 (2 GB, for smaller PCs). On a tiny model (1B and under) she warns you it may talk nonsense and offers a better one.
• Online, no account: Pollinations, nothing to set up.
• I have a key: Groq or Gemini (both have a free tier), OpenRouter, OpenAI, Mistral or DeepSeek. You paste your key in her panel and she checks it. It's kept on your PC, encrypted with your Windows account, and only ever sent to that service.

Her menu › AI model lets you switch later: Set it up with her…, or straight to a service and a model, LM Studio (:1234), llama.cpp or vLLM (:8080), any OpenAI-compatible server (API key or address…), or Claude Code itself: your messages go to claude -p in the folder you pick, continuing one conversation, and her hooks show what it does. In that last one, permission mode default only lets it read (nobody is there to say yes); acceptEdits lets it edit files without asking. Forget our conversations clears what she remembers of your chats.

It's AI. Her replies are written by the model, not by the show's writers: it's a fan version of her, and the chat panel says so every time.

What she can do on your PC (Windows), when you ask her in the chat:

• Open an app or a game: anything in your Start menu (Store apps like Spotify included), your Steam and Epic games ("open Spotify", "launch Brawlhalla"). Named in your own words, it opens right away; if only her AI came up with it, you get a button first.
• Music: "pause", "next", "louder", "mute"… press the media keys, so it works with Spotify and most players, right as you send it. "Put Daft Punk on Spotify" opens Spotify on a search for it (the app if you have it, else the site).
• A website: always behind a button showing where it goes.
• Close an app ("close AM Music", "can you shut Discord down?"): a button with the app's name, and nothing happens until you click it. She closes it the way its own close button does, so it can still ask you to save. If it only hid in the tray, she offers Force quit, again only on your click (unsaved work is lost then). She never closes Windows' own pieces, Claude, Ollama or herself.

Nothing else: she can't see your screen or your files.

Right-click her › Make her yours… (or "Make me yours" in her guide), one panel at a time, each one skippable:

• What she calls you. She uses it now and then, and comes online with it ("Capri online. Hi, Max.").
• How she is, in your words ("more teasing, and talk to me about Night City"): her chat follows it. She stays Capri.
• Lines of yours, that she says now and then with hers when you click her. Write {name} in one and she puts your name there.
• Things to remember (your favorite game, your cat, D…): her chat keeps them in mind.

In her chat, "call me Léa" and "remember that my cat is called Neko" work too. All of it stays in her settings on your PC.

She only catches the mouse on her actual body (pixel-precise): the rest of the screen works as usual.

• Click her: she tells you where Claude is at (nothing going on: a Talk to me button, to chat with her).
• Drag her: move her around.
• Click the panel: it closes.
• Ctrl+Alt+C: she puts herself away (into her biochip, like in the show) and all that's left of her is her mask, eyes shut, in the bottom-left corner. Her eyes only open when Claude needs you. Click the mask (or Ctrl+Alt+C again) to bring her back.
• Her menu: right-click her (it's also on her tray icon, next to the clock): teleport, look at the satellite, demo, how it works, mission report, talk to her, size, sound, screen, AI model, wander, possess your windows, language, start with Windows, hooks.

She speaks French, English, Spanish, Brazilian Portuguese and Russian, and picks the language of your system on her own. You can choose another one in her menu.

1. Download Capri-Setup-x.y.z.exe from the latest release and run it. It installs for your user only (no admin rights), adds a desktop shortcut and starts Capri. You don't need Node.js or anything else.
2. The installer isn't signed (a code-signing certificate costs money), so Windows SmartScreen may say "Windows protected your PC": click More info, then Run anyway.
3. Capri shows up and introduces herself. Click Plug me in: that connects her to Claude Code.
4. Close Claude Code completely and open it again (it reads its hooks when a session starts). As soon as Claude does something, she tells you "I can see Claude!": that's how you know it worked.

Her menu: right-click her. It's also on her tray icon, which Windows 11 often hides behind the ^ next to the clock.

Claude Code is Anthropic's coding assistant: in a terminal, in VS Code, or in the Code tab of the Claude app. It needs a paid Claude plan (Pro or higher) or an API account. Capri only watches it: no API key, and nothing to pay for Capri herself.

Without Claude Code she still lives on your desktop: she floats, sits on your windows, looks at the satellite, falls asleep. You can just leave her there.

You need Node.js 20 or newer.

git clone https://github.com/mochiiwuff/capri-desktop.git
cd capri-desktop
npm install
npm start

Keep that terminal open while she runs. Not tested on macOS or Linux yet: she should start, but the window tricks (sitting on your windows, possessing them, showing Claude's answer when you're elsewhere) are Windows-only, and on Linux the transparent overlay works best on X11 (Wayland can struggle with click-through windows).

Right-click Capri, then Install Claude Code hooks. Or from the command line:

npm run hooks:install

This adds a hook to ~/.claude/settings.json (a backup is written next to it, your existing hooks are kept). Restart your Claude Code sessions afterwards. To remove it: npm run hooks:uninstall.

The hooks run async: they never slow Claude down, and when Capri isn't running they do nothing.

Right-click her › Watch › Codex or Antigravity. She says hi and offers to plug herself in, like she does for Claude Code. Then:

• Codex: restart it and trust her hooks when it asks. They go in ~/.codex/hooks.json. Her hook for Codex needs Node.js 20 or newer on your PATH.
• Antigravity: start a new conversation. Her hooks go in ~/.gemini/config/hooks.json.

She follows one of them at a time, the one picked in her menu, and her lines, her guide and her chat use its name. She only watches: when Codex or Antigravity asks for approval, you still answer it there. From the command line: npm run hooks:codex:install or npm run hooks:agy:install (:uninstall to remove them), and npm run test:hooks runs the tests of both adapters. Watch › Nothing, just keep me company: she stops talking about any of them.

npm run demo

Replays a fake session from start to finish (reads, a web fetch, a subagent, writes, a failing test, a permission prompt, the end), then shows everything she does on her own, a line before each trick: the other minds in her, zapping your pointer, the whole satellite sequence, possessing a window (a little terminal opens for her, then closes under her and she falls), sleeping down to her mask, and putting herself away in the bottom-left corner. It's also in the tray menu, in her language; from the command line it's in English, or add one: npm run demo -- fr (or es, pt, ru).

Every sound is synthesized live (Web Audio), nothing copyrighted ships with the repo. You can drop your own files in the custom sounds folder (tray › Sound › Open custom sounds folder), named like this (.mp3, .wav, .ogg or .m4a):

• All of the code is right here. The installer is built from it with npm run dist; you can build your own.
• Nothing leaves your PC (see below): she only talks to Claude Code through a hook on 127.0.0.1.
• What she changes on your system: the hook in ~/.claude/settings.json (a backup is written first, and you can remove it from her menu), and a startup entry only if you tick "Start with Windows". She uninstalls like any app, from Windows Settings › Apps.
• The SmartScreen warning comes from the installer not being signed, not from anything it does.

• Mac, Linux? No installer yet, but you can run her from the source (see above).
• Phone, Android? No, she needs a desktop.
• Other assistants? Claude Code, Codex and Antigravity: her menu › Watch. Cursor, Windsurf and Gemini CLI: not yet.
• Ollama? Two ways. Claude Code running on a local model through Ollama (ollama launch claude): she sees it like any Claude Code, it's just slower, and her ticker counts the seconds while it thinks. And she can chat with you through Ollama herself: see "Talk to her".
• She barely moves, her intro just fades in and out. Windows has its animations turned off (Settings › Accessibility › Visual effects › Animation effects), and she follows it. Her menu › Animations › Full makes her move anyway; the first time, she asks.
• Can I turn her off? Ctrl+Alt+C puts her away, Quit in her menu closes her. Claude Code works exactly the same without her.
• She only floats around and says idle things. That's normal until Claude Code does something. If it never reacts, check her menu says "Claude Code hooks: installed", then close Claude Code completely and open it again.

Nothing. The hook only keeps what the display needs (tool name, file path, command, the start of your prompt, Claude's last message up to 6,000 characters so she can show it to you, all truncated) and sends it to 127.0.0.1 only. Your file contents are never sent: for a write, only its size goes through.

Her chat goes to Ollama on your PC (127.0.0.1:11434, or OLLAMA_HOST) with what she knows of the moment (the project's name, Claude's last action, today's counts). Her mission log stays in her own storage on your PC.

The goal: she should feel like she stepped out of the anime, not like a widget.

• Cel animation: her body is redrawn 12 times a second ("on twos") like anime, 24 during teleports. Every drawing has a slight boil (the wobble of a line redrawn by hand).
• Frame by frame, pose to pose: nothing is tweened. Each move is an exposure sheet (acting.js): key drawings held for a few frames, an anticipation the other way, a smear frame with multiples of the head, an overshoot, holds. Her idle float is four drawings, not a sine wave.
• She acts with her head and her mane, like in the show: the cocked head, the shards bristling or blowing wide, the manic laugh with the head shaking on every drawing, the slump when she sleeps. The cut-out is rigged so her head tilts around the neck, her mane flares unevenly around a rigid face, and her thighs fold (foreshortened, seen from the front) so she can sit with her lower legs swinging.
• Squash and stretch, afterimages: the flat cut-out squashes to a sliver to turn around, stretches when she falls, flattens when she lands, and splits into green and red copies (the other minds in her) when she spins or laughs.
• The satellite, after the season's ending, where she points at the light in the sky and wonders if they could make it up there: a point of light crosses the top of the screen, slowly. Most of the time she just looks, reaches, it twinkles, she sighs. The first time of the day, and a little while after a long Claude job, it's the whole sequence, in five beats (and nothing distracts her meanwhile, not even your pointer):
  1. Hush: she freezes, and the white specks of her mane lift off into a constellation over her.
  2. The reach: she reaches out (the drawings bunch up as the hand gets there) and her stars line up into a road from her fingertips to the satellite.
  3. Anticipation: she coils up, the arm pulls back a little, sparks crawl in her hand, cut-in on her eyes.
  4. The red light goes up: a heavy tapering bolt races up in three drawings, the first one in negative (an impact frame), the stars light up as it passes, speed lines on the satellite, and she's lifted with it.
  5. The answer: the bolt snaps and the pieces fall. A beat of silence, then the satellite twinkles twice. Her stars come home, her mane flares bright for a moment, and her hand drops with a sigh.
• Her arms grow when she aims: anime exaggeration, or a raised arm would get lost in her mane. It stretches along its length only (it stays as thin) and no longer gets bent by the head and the mane.
• Both arms match: the cut-out had one arm reaching and one hanging. The hanging one is removed (tools/build-sprite.py) and the shader draws the reaching arm mirrored in its place, so both hands are the same claws and both arms can act. Where an arm crosses her body or her mane it gets a violet line, so it reads.
• Her texture: the red mane is pushed back to the show's hot red and covered in twinkling white specks. Shards come loose from it and drift away.
• The violet offset: like in the anime, a misregistered violet copy under her, under the panel, under the shards.
• "Relic" glitch: shifted horizontal slices and RGB split, in the spirit of Johnny Silverhand's appearances.
• Teleport: charge, shards, collapse into a line, and where she was, a black slit with a red line in it, like in the show. A red column of light to the sky, a bolt to the destination, her pieces (mane shards and the green stars of her eyes) spiralling back in, back with two impact frames.
• Her intro: a close-up of her, cut out so your desktop shows around her mane (tools/build-intro.py), in six drawings swapped like cels (at rest, her mouth ajar, half open and wide open for "hi", her hand tilted one way and the other for the wave, on threes), and everything else is animation on top: impact frames (her as a flat white then ink silhouette), an RGB split that settles, screen shake, the line boiling on twos, her eyes redrawn over the picture's so they can look around and blink, the camera creeping in, the tag slamming on. Never a straight edge of the picture on screen: it shows through jagged cuts that move (her arms from the sides in, then breaking off from the hands in, then just her head for the dive, with afterimages and her zigzag).
• Cut-ins: close-ups of her taken from the show, pushed in, with speed lines: her grin or her laugh after a finished job, all her eyes when Claude is waiting on you, her eyes right before the red light, her sideways look after zapping your pointer. Her face in the panel changes with what she's saying, too.
• Her mask: a vector drawing after the show (and the "Capri Wink Face"), on its own small canvas, only redrawn while on screen: the green slab of a face, the hooked spike, the white fang, the blue almond eyes, and the eyes shut as chevrons while she sleeps.
• Type: Chakra Petch (bevelled cuts, like her shards) + JetBrains Mono for data.

If Windows is set to "Show animations: off", she sticks to fades.
