I’ve been building toward something I don’t have a clean name for yet. The pieces — local AI, on-device speech, the phone-as-remote, hands-free voice loops — exist and ship today. The pattern they form, when you put them together, doesn’t have a settled vocabulary. So I’m coining one. Not because I want to invent jargon, but because a thing without a name doesn’t exist for most people, and this thing is going to exist for everyone within a few years.
Here’s the working glossary. Use these terms. Argue with them. Replace them with better ones if you can think of any. The goal is to give shape to a way of working with computers that’s already real but not yet common.
The Rectangle
Noun. The screen. Short for the glowing rectangle of damage. The thing you’re hunched in front of right now. The thing that defines posture, attention, work pace, and back pain for most people who use computers professionally.
“I want to spend less of my day inside the Rectangle.”
The Rectangle is not bad. It’s just been the only option for so long that people forgot it was an option at all rather than the default state of computing. Once you have a working alternative — and you do now — the Rectangle stops being a given. It becomes one of several places work can happen.
Off-Screen Work
Noun. Productive computing done without facing a screen. The opposite of screen work, not the absence of work. Hands-free voice coding is off-screen work. Texting your Mac from the hot tub and getting back a finished research summary is off-screen work. Listening to your AI narrate a long task in your own cloned voice while you walk around your house is off-screen work.
“Half my morning was off-screen. I shipped more than I usually do at a desk.”
Ambient Computing
Noun. Computing that happens around you instead of in front of you. The machine listens, talks back, sees what you point a camera at, and the keyboard becomes optional rather than mandatory. Ambient computing isn’t smart speakers. Smart speakers ask you to talk to a brand. Ambient computing is your own machine, doing your own work, in your own voice, in the room with you.
“I’m building toward ambient computing — a stack you can talk to, hand things off to, and check back on later.”
To Airgap (verb)
Transitive verb. To configure an AI workflow such that it runs entirely on local hardware with no outbound network traffic — making client data, prompts, and responses physically incapable of leaving the machine.
“We airgapped the firm’s drafting workflow last week. Nothing they paste into the AI hits the internet.”
This is the verb form of AirGap AI, the consulting practice I run for firms in regulated industries. It’s also the right word for what you do when you set up your own local-AI stack on a MacBook and turn the wifi off to prove it works. Both of those count.
Hand-Off Computing
Noun. A workflow where you give the computer a task, walk away, and it tells you when it’s done. Distinct from interactive computing, where you sit and wait, and from background computing, which you forget about until it crashes. In hand-off computing the machine knows you walked away, finishes the work, and notifies you back through whatever channel you set up — usually a text to your phone.
“I just hand-off it the data analysis and go make breakfast. It buzzes my phone when the report’s ready.”
The Two-Slab Posture
Noun. The body shape you assume when working with a laptop and a phone simultaneously — head tilted forward, shoulders rounded, both hands pulled in toward the body. The dominant posture of professional computing in 2026, and the source of much of the chronic pain that office workers attribute to “stress.” The Two-Slab Posture is what off-screen work makes optional.
“By 4pm every day I’m locked in the Two-Slab Posture and I can feel it in my neck.”
Backpack Supercomputer
Noun. A current-generation laptop with enough on-device compute to run frontier-class AI models locally. Specifically: an Apple Silicon MacBook Pro with 64+ GB of unified memory, of the M2 / M3 / M4 / M5 Max generation. The phrase emphasizes that this hardware fits in a backpack while delivering performance that would have required a server rack five years ago.
“My M5 Max is a backpack supercomputer. I take it to client offices and it runs a 70-billion-parameter model on the train ride.”
The Ambient Stack
Noun. The minimum set of pieces required to assemble an ambient-computing setup. As of 2026, on Apple hardware:
- A local LLM running through an MLX-native server. (claude-code-local.)
- A continuous-listen daemon wrapping
SFSpeechRecognizer. (NarrateClaude.) - A cloned-voice TTS for spoken responses in the user’s own voice.
- A phone bridge so iMessage can drive the Mac. (Custom AppleScript.)
- A local browser agent for web tasks. (browser-agent.)
Five components. All open source. All run on hardware you may already own. The entire stack costs $0 in recurring fees once installed.
To Whisper-Code
Verb. To do programming work via voice, with the AI replying in the developer’s own cloned voice. Distinct from voice dictation (which still requires you to be at the screen to read the result). Whisper-coding is an end-to-end conversation about code, in audio, where the developer never has to look at the screen unless they choose to verify something visually.
“I whisper-coded the fix while pacing the kitchen. Saw the diff after lunch and it was right.”
The Cloned-Voice Loop
Noun. A feedback loop where the AI’s spoken responses are rendered in a TTS clone of the user’s own voice. This makes the response feel less like an external announcement and more like internal monologue, which the human nervous system processes more naturally and at lower cognitive load than a stranger’s voice. The loop runs on-device for the same privacy reasons as the rest of the ambient stack.
“After a week with the cloned-voice loop, hearing a stranger TTS feels jarring.”
Hot-Tub Coding
Noun. Sending a coding or research task to your Mac from your phone while not being at the Mac. Originally literal — sending the task while in a hot tub — now a generic term for any phone-driven hand-off computing session. The hallmark of hot-tub coding is that the human is doing something else entirely while the computer is doing the work the human ordered.
“That whole feature was hot-tub coded. I never sat down to write any of it.”
Local-First AI
Adjective phrase. A system architecture in which AI inference defaults to running on the user’s own device, with cloud as a fallback used only when local can’t handle the task — not the other way around. The cultural and technical opposite of cloud-first AI, which has been the default since 2019. Local-first AI is the architecture every privacy-sensitive industry is now going to need, whether they realize it yet or not.
“For NDA work, the only sane architecture is local-first AI.”
A Note On Ownership
These words don’t belong to me. If you find them useful, use them. If you build on the stack and coin a better word for something I’ve named here, I’ll switch to using yours. The point of giving things names is to make them discussable, not to lock down a vocabulary.
But I do want the pattern they describe to take hold. We have, in 2026, the technology to fundamentally change how working with computers feels — physically, mentally, ergonomically, financially. Most people don’t know it yet because the pattern doesn’t have a name they recognize. These are the names I think will help.
If any of this resonates: clone the open-source stack, assemble your own ambient setup, and tell me what you find. The next decade of computing isn’t being decided in any one company’s roadmap. It’s being decided by who shows up and starts using the parts that already exist.

Part of the Nice Dreamz lineup. If you’re a firm that wants the ambient stack installed and air-gapped for compliance reasons, AirGap AI is the engagement I do for that.
