Catai - Ollama를 통해 채팅하는 macOS용 가상 픽셀 아트 고양이

Virtual desktop pet cats for macOS — pixel art cats that live on your dock, chat with you via Ollama LLM, and debate ideas together to help you brainstorm and refine your thoughts. - Dock companion — Cats walk along your dock with pixel-perfect animations - Window perching — When dock auto-hides, cats teleport to sit on top of your active window - Multi-cat — Up to 7 cats with distinct colors and personalities - AI chat — Click a cat to open a pixel-art chat bubble, powered by Ollama - Cat Debate mode — Your cats debate any topic together! Each cat argues from its personality, then they synthesize a final answer. A creative brainstorming & idea-refining tool - Mouse tracking — Cats notice your cursor and turn to look at it. Get too close and they'll chase it! - Random meows — Cats spontaneously say "Miaou~", "Prrr...", "Mrrp!" in cute speech bubbles - Pixel art UI — Settings panel, chat bubbles, and controls all in retro pixel style - Menu bar icon — 🐱 icon with quick access to settings and quit - Retina ready — Nearest-neighbor scaling keeps pixel art crisp on HiDPI displays - Multilingual — French, English, Spanish (switch with flag buttons) | Color | Default Name | Personality | Skill | |---|---|---|---| | 🟠 Orange | Citrouille | Playful & mischievous | Jokes & puns | | ⚫ Black | Ombre | Mysterious & philosophical | Deep questions | | ⚪ White | Neige | Elegant & poetic | Poetry & grace | | 🔘 Grey | Einstein | Wise & scholarly | Science facts | | 🟤 Brown | Indiana | Adventurous storyteller | Epic tales | | 🟡 Cream | Caramel | Cuddly & comforting | Emotional support | | 🐾 Percy | Percy | Retro geek & hilarious | 80s-90s internet references | Each cat has 368 hand-drawn sprites across 8 directions: - Walking / Chasing — 8 frames per direction (all 8 directions!) - Eating — 11 frames per direction - Drinking — 8 frames per direction - Angry — 9 frames per direction - Waking up — 9 frames per direction - Idle / Looking / Sleeping — Static rotation sprites (8 directions) - macOS 14+ (Apple Silicon or Intel) - Ollama running locally (for chat feature, optional) Grab CATAI.zip from Releases, unzip, then: xattr -cr CATAI.app # remove macOS quarantine (app is unsigned) open CATAI.app ./build.sh open CATAI.app swiftc -O -o cat cat.swift -framework AppKit -framework Foundation ./cat No Xcode project, no dependencies, no package manager — just one Swift file. Click the 🐱 menu bar icon → Settings: - Language — 🇫🇷 🇬🇧 🇪🇸 click a flag to switch - Cats — Click a color bubble to add a cat, click × to remove - Name — Rename each cat - Size — Pixel art slider to scale cats - Ollama model — Select from your installed models - Debate mode — Toggle on/off to enable multi-cat brainstorming - Single native Swift file (~2000 lines), no external dependencies NSWindow with transparent background for overlay renderingCGWindowListCopyWindowInfo for detecting frontmost windows- Dock auto-hide detection via mouse position polling at 30 FPS - Color tinting via direct pixel manipulation in sRGB CGContext - Ollama streaming chat via URLSessionDataDelegate - Conversation memory persisted in UserDefaults . ├── cat.swift # Entire application (single file) ├── build.sh # Build .app bundle script └── cute_orange_cat/ # Sprite assets ├── metadata.json # Animation & rotation definitions ├── rotations/ # 8 static direction sprites (68x68 PNG) └── animations/ # 5 animations × 8 directions × 8-11 frames ├── angry/ ├── drinking/ ├── eating/ ├── running-8-frames/ └── waking-getting-up/ - Focused debate — cats now stay strictly on the user-supplied topic - System prompt rewritten as 6 strict rules: stay on topic, never derail, attempt creative tasks, personality is just tone, react to others, 2 short sentences - Each turn re-asserts the topic in the user message → no more drifting from "write a poem" to "what's a dinosaur" - Final synthesis now actually delivers the requested artefact (poem, plan, idea) instead of meta-summarising - Non-intrusive bubbles — debate bubbles no longer steal focus from your work - New passiveMode :ignoresMouseEvents = true ,canBecomeKey = false , no input field, no buttons - Uses orderFrontRegardless (display only) instead ofmakeKeyAndOrderFront +NSApp.activate - You can keep typing in your editor, switching apps, etc. — the debate just unfolds visually above your cats - New - Clicks on cats are ignored during a debate (no accidental flow break) - Bubbles auto-revert to interactive mode 8s after the synthesis appears - Debate engine rewritten as a stateful class — eliminates Swift 6 Sendable warnings - Validates each cat still exists before its turn (survives mid-debate cat removal) - Generation counter invalidates stale callbacks if the debate is stopped DispatchQueue.main.asyncAfter instead ofTimer.scheduledTimer from URLSession queue- Public stop() called fromremoveCat andapplicationWillTerminate - Debate button now appears reliably (didSet observer triggers bubble rebuild) - OllamaChat session race fixed — no more stale callbacks clearing newer requests - Memory — tintCache bounded (NSCache , 600 items),getPreview cached, orphanmem_ purged at startup,URLSession properly invalidated - Robustness — fatalError at startup →NSAlert with clear message,addCat rolls back on failure,frontmostWindowFrame cached (200 ms) to avoid hammeringCGWindowListCopyWindowInfo - Code organisation — BehaviorTuning enum centralizes AI tuning knobs,Dictionary.localized() helper dedupes the L10n fallback pattern - Build is now clean: zero warnings, zero errors - Debate mode — Your cats now debate any topic together in a dedicated window - Each cat argues from its unique personality (philosopher, geek, poet, scientist...) - 3 rounds of discussion where cats react to each other's arguments - Final synthesis/consensus by the moderator cat - Enable/disable via toggle in Settings - Debate button in chat bubble — When debate mode is on, a "🎤 Débattre !" button appears in each cat's speech bubble - Non-streaming Ollama API for reliable multi-turn debate exchanges - Fix: Chat bubble input no longer loses focus when cat is walking - CATAI is no longer just a desktop companion — it's now an idea refinement system powered by multiple AI personalities - New 7th cat: Percy — white-grey cat with a unique personality - Percy's dad is the "king of the internet" — he drops 80s-90s internet references (Astalavista, GeoCities, Netscape, IRC, BBS, AOL, 56k modems, ICQ...) - Custom pixel-level desaturation tinting for Percy's white-grey look - Custom bicolor bubble in the cat color picker - Cat name displayed in chat bubble - Performance: Sprite tint cache, conditional image updates, shared mouse polling, reduced dock polling - Cats now look toward your cursor when it's nearby (8 directions!) - Cats chase the cursor when it gets close enough - Sleeping cats wake up if you wave the cursor near them - Centralized UI color palette for consistency - Simplified Ollama model fetching - Fixed angle mapping gap at 360 degrees - Code optimizations ( hypot , removed dead code) - Fix cats floating after resize or dock refresh - Fix chat bubble losing position near screen edge - Remove force unwraps with safe fallbacks - Fix potential crash in clamshell mode - Fix memory leak on quit (monitors & timers) - Fix fragile scale slider timer - Multi-cat support with 6 color variants - Distinct AI personalities per color - Pixel art UI with custom controls - Walk on dock and window title bars - Random meow speech bubbles - Chat memory persistence - macOS .app bundle with build script Multiplatform port in progress (Tauri v2) — Windows & Linux coming soon! 🐱✨ A huge thank you to Korben.info for the mention!
