I'm Matt Macosko. I build open-source AI + robotics from Humboldt, CA.
This page is everything I've shipped — phone apps, local-AI tools, agents, and robots. All of it runs on hardware you own, and all of it is free to fork on GitHub.

📱 iPhone & Android Apps
Built start to finish on this stack, shipped to both stores. Private by default, pay once or nothing.
▲ 22 vs last week
Updated Sep 27, 2026 from Apple and Google's own reports, twice a day. First-time downloads only, no updates or re-downloads. Google Play runs about two weeks behind.
RealTime AI Camera
Tells you what it sees, out loud — describes a whole room or a whole page, reads printed text, names 601 kinds of object, measures distance. All on-device. Built for VoiceOver and TalkBack. Free, no ads, no cloud calls.
Song Forge
Describe a song in any of 19 languages and own a full-length original in minutes. No subscription, every song 100% yours.
Brainforest
Complete K–4 learning adventure — 2,000+ activities, a narrator that reads everything aloud, 100% offline. No ads, no accounts, nothing tracked.
RealTime Space
Fly the whole solar system — photoreal planets with real NASA imagery, living Sun, real eclipses, 60 fps.
Claude Code Local · AirGap AI
Run Claude Code 100% on-device. MLX-native Anthropic-API server with a six-model local lineup — Muse-Glimmer 30B (multimodal), Gemma 4 31B, Qwen 3.5 122B at 65 tok/s, DeepSeek V4 Flash with 1M context. Zero cloud, zero API fees. The same stack is AirGap: the full private-AI build for firms that can't put client work in the cloud.
Hugging Face · divinetribe
The model side of the stack. 16 MLX-quantized open-weight models — Llama 3.3 70B, Gemma 4 31B and 12B, Hermes 4 14B, Qwen3-VL 32B vision, Qwen3.6 27B, Nemotron-3 Nano Omni, Muse-Glimmer 30B — plus CoreML detectors. The exact files that ship with claude-code-local and the RealTime AI Camera iOS app. Live download counts, no cloud inference, run on your own M-series Mac.
🍏 MLX model engineering
Porting frontier model architectures to run natively on Apple Silicon — the layer everything else stands on.
nemotron-omni-mlx
NVIDIA's tri-modal Nemotron Omni — text, vision and audio — running entirely on Apple Silicon. Pure MLX runtime, parity-verified against NVIDIA's reference.
🧠 The local-AI stack
One Mac: brain, ears, eyes and hands — plus the phone in your pocket. Ambient computing that never phones home.
AirGap
The full private AI workstation build: one Mac, wifi off, nothing leaves the building. A capability I keep sharp — the whole stack is open source.
claude-failover
Backup brain for Claude Code. Hit your plan limit or an outage — flip one command and keep working on local models.
NarrateClaude
Hands-free voice loop — Apple speech recognition in, cloned-voice TTS out. Both directions fully on-device.
SpeakAnywhere
Dictate into any app and have any text read aloud in natural voices, all on your own PC. New: a free Windows download.
browser-agent
Local MLX + Chrome DevTools Protocol. Drives a real browser autonomously — iframes, Shadow DOM, ProseMirror.
claude-screen-to-phone
Control Claude from your iPhone via iMessage. Text commands in, screenshots and videos out.
FiaOS
Open a browser tab → you're driving your Mac mini. Live screen, real PTY shell, on-device voice.
studio-record
macOS screen + facecam recorder with a local HTTP API. Pairs with Claude Code for record-and-send pipelines.
🕹 Agents & benchmarks
Agents doing real work on real machines — and the leaderboard that keeps them honest.
🛠 Developer tools
Small, dependency-free tools that solve real problems in a local-AI shop.
Trinidad Head
New: a terminal written from scratch in Rust for Windows and Mac. Glass windows with a neon glow, a different color for every window, and a Claude Code prompt you can edit like a text box. Free download.
Moonstone
New: one window for every Claude Code session on every computer you own, Mac or Windows. Push to talk, answers read out loud, and local models in the same list.
modelaudit
Find the license landmines in a local AI stack — including the ones inside the model weights. No dependencies, runs offline.
whobuilt
A credits file that names the people, not just the packages — resolves every dependency back to the humans who wrote it.
🦾 Robots & open hardware
Building toward a modular-robot-parts future — local AI vision in things you can actually touch.
Cemani Homestead Robot
1kW autonomous tank platform — LIDAR, 601-class object detection, iMessage natural-language control, Jetson brain. The coop robot whose eyes became RealTime AI Camera.
VisionBuilder
Roboflow on your phone — label photos and train your own on-device vision model for a robot, privately, from the camera roll.
Sky Tribe eVTOL
Open-source single-seat amphibious electric VTOL (FAA Part 103 ultralight). Lands on water and takes off again. Full CAD.
🧬 Science, medical & education
Side quests that turned into real results — research, thesis defenses, and one little kid's tutor.
Parkinson's Vulnerability Predictor
Cross-cohort test of whether AGTR1+ dopamine neurons are selectively lost in Parkinson's — 579,931 cells, four independent datasets, same direction in all four.
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 and freshwater restoration, and a 13-chapter scientific-diving deep dive. Hand-coded SVG, offline-ready, each page reads itself aloud. Built end-to-end in Claude Code.
🎨 Creative
Films, worlds and toys — all generated or hand-built on the same local stack.
Story Forge
Turn a story into a finished film on one Mac — stills, motion, voices, music, grade and sound. The pipeline behind The Lucid Engine, Antarctica, and The Bear Sister.
The Farmstand 3D
Immersive WebXR virtual cannabis marketplace built with A-Frame. Live at marijuanaunion.com/marketplace/.
Like what you see? You can now sponsor me directly.
All of this is free and open, and you can run everything on your own Mac without paying me a dime. If it saved you an afternoon, a few dollars a month keeps me building in the open.
Who's behind all this
Matt Macosko, working out of Humboldt, 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. Nearly everything is MIT. Break it, ship something with it.
- A firm that handles private client documents? AirGap is what a full private build looks like.
- Just someone who likes what I'm building? Sponsor the work or follow along on GitHub, X, or YouTube (@nicedreamzapps — full demos).
