Open-source AI + robotics,
built in public.
Local AI stacks, autonomous robots, on-device computer vision, and one very opinionated NDA analyzer. Everything ships as real code you can fork — not slideware.
Claude Code Local · AirGap AI
Run Claude Code entirely on a MacBook. 122B-parameter model at 65 tok/s with Google TurboQuant, zero cloud, zero API fees. The same stack underpins AirGap AI — a commercial service for law firms reviewing NDAs and privileged documents on-device.
🧠 The local-AI stack
Three repos, one MacBook. Brain + ears + hands. Ambient computing that never phones home.
claude-code-local
MLX-native Anthropic server + local model lineup (Gemma / Llama / Qwen). The brain of the stack.
NarrateClaude
Hands-free voice loop — Apple SFSpeechRecognizer + cloned-voice TTS. Both directions fully on-device.
browser-agent
Local MLX + Chrome DevTools Protocol. Drives a real Brave browser autonomously — iframes, Shadow DOM, ProseMirror.
claude-screen-to-phone
Control Claude from your iPhone via iMessage. Text commands in, screenshots + videos out.
studio-record
macOS screen + facecam recorder with a local HTTP API. Pairs with Claude Code for record-and-send pipelines.
Song Forge
Local AI music generator — type a vibe, get a whole song with lyrics + vocals in 15 seconds. ACE-Step + Gemma + seed-vc voice swap, all on-device.
FiaOS
Open a browser tab → you're driving your Mac mini. Live screen, real PTY shell, on-device voice. Self-hosted remote workstation.
JaneOS
Adaptive learning tutor for one little kid. Voice-driven, theme-rotating, generates fresh activities. Built with Claude + Piper TTS, all local.
🦾 Robots + on-device vision
Building toward a modular-robot-parts future — Lego-like clip-in modules with local AI vision.
Cemani Homestead Robot
1kW autonomous tank platform — LIDAR, 601-class object detection, iMessage natural-language control, Jetson brain.
RealTime AI Camera
Free iPhone app detecting 601 object classes on-device. No ads, no subscriptions, no cloud calls.
🧬 Medical + research
Side quests that turned into real results.
Parkinson's Vulnerability Predictor
Machine-learning tool predicting dopamine-neuron vulnerability. 100% accuracy on a 20-gene signature.
Divine Tribe Chatbot
Hybrid chatbot + email support with shared RAG/CAG intelligence, Claude-powered. Runs Divine Tribe customer support.
🌊 Science + Education
Open educational science projects — built for thesis defenses, classrooms, and outreach.
Dan Close · Aquatic Ecology & Restoration
An HSU Master's Thesis project at Cal Poly Humboldt Marine Sciences. Four single-page features — molecule-to-whale scale of the sea, marine restoration, freshwater restoration, and a 13-chapter scientific-diving deep dive. All hand-coded SVG. All offline-ready. Each page reads itself aloud in a Microsoft neural voice. Built end-to-end in Claude Code.
🛸 Creative + film
Side projects that aren't software at all — fan sites, interactive experiences, things made for fun.
Like what you see? You can now sponsor me directly.
All of this is free. The code is public, the models are open, and you can run everything on your own Mac without paying me a dime. But if it saved you an afternoon — or saved your firm from sending a client's NDA to someone else's server — a few dollars a month keeps me building in the open instead of chasing a day job.
Sponsorships go through GitHub directly to Nice Dreamz LLC. Cancel anytime. No tiers, no paywalled features, no "premium Discord." Just honest support for honest work.
Who's behind all this
Matt Macosko, working solo out of Arcata, CA. Nice Dreamz LLC. Decades of physical-product iteration before AI accelerated everything into software. Started with a chicken problem. Still figuring it out.
Three ways to engage, depending on who you are:
- A developer / hacker? Fork any of the repos. Everything is MIT. Break it, ship something with it.
- A firm that handles private client documents? The AirGap AI pilot is the commercial version, packaged as a 14-day engagement.
- Just someone who likes what I'm building? Sponsor the work or follow along on GitHub, X, or YouTube (@nicedreamzapps — full demos).
