Voltare
Voltare · independent engineering studio · South Carolina, USA

Software from first principles.

Voltare is an independent engineering studio. It designs programming languages, translates software between platforms, writes its own compressors and browsers, and ships apps people use at work. The method is AI-first: agents do most of the typing, one engineer makes the decisions, and nothing ships until it passes on real machines.

How the studio works

Three rules
1

Build the thing itself.

When the interesting part is the engine, Voltare writes the engine. AIL has its own code generator. Clove has its own compressor. Garlic has its own HTML parser and layout. Where it matters, the core is written in-house rather than wrapped.

2

AI-first, human-directed.

AI agents write most of the code. One engineer makes the design calls and writes every one of them down: more than 780 decision records on AIL alone. The tools are built so agents can read their output as easily as people can.

3

Proven on real machines.

Changes have to pass test gates on the studio’s own machines, across macOS, Linux and Windows, before they land. Apps are tested by hand. Hardware tools check the exact device and firmware, and refuse anything they have not been verified against.

Selected work

A runtime, a language, five programs, an app
01

Mac.apk

What
Android app runtime for macOS
Stack
Java, C++, Objective-C++, Metal (not AIL)
Status
Public alpha, open source (AGPL + commercial)

Runs Android apps on Apple Silicon Macs as ordinary Mac apps. No emulator, no virtual machine, no Linux kernel underneath.

Mac.apk implements the Android application environment directly on macOS. App code is converted once and run on a built-in Java runtime, ARM native libraries execute on the Mac’s own CPU, and graphics go to the GPU through Metal. Apps get a Dock icon, a real window, and light and dark mode.

It ships as a signed, Apple-notarized download with its own installer, updater, compatibility list and wiki.

AIL

What
AI-first programming language and toolchain
Targets
macOS, Linux, Windows on x86-64 and ARM64
Status
Pre-1.0, private preview

A programming language designed for AI agents and the people directing them. The whole language fits on a card of about 8,000 tokens, so an agent can hold all of it in mind while it works.

AIL is built for efficiency at both ends. For the agent: dense syntax, one canonical layout, and a compiler that answers structured questions, so it can ask what a function is allowed to do instead of guessing. For the machine: memory-safe native code for macOS, Linux and Windows, with no C compiler, no LLVM and no package manager in the loop. The compiler is written in AIL and builds itself.

The code is written by AI agents under one human designer who makes the design calls. Every change has to pass test gates on real machines, and every decision is written down: more than 780 design records so far.

fn half(n int) int
    requires n >= 0          # contract: false traps
    ensures result * 2 <= n  # `result` is the returned value
    n / 2

fn main()
    print("half of 9 is {half(9)}")

03

Built in AIL

What
Five real programs that prove the language. (Mac.apk is not one of them.)
Rule
The parsers, codecs, layout and OCR are written in AIL, not borrowed.
Status
Private preview

A language is only as good as what you can build in it. So Voltare built a web browser in it. Then an archiver, a PDF reader, an editor and a disk analyzer.

CloveAn archiver built on a new context-mixing compressor. Integer-only, so every machine produces identical bytes. Benchmarked against gzip, xz, zstd and 7-Zip.compression

Clove’s own benchmark script, run on an M2. Tighter than gzip -9; zstd -19 and xz still pack smaller.

Equipment Service Tool

What
Field reference app for heavy equipment technicians
Runs on
iPhone, iPad, Mac, Apple Vision
Status
On the App Store

J1939 fault codes, torque tables and electrical calculators for technicians working where there is no signal.

SPN and FMI fault code search for Allison, Bomag, Cummins, Deutz, Hyundai, Manitou, XCMG, Sakai and more, with Ohm’s law, unit conversion, refrigerant charge and bolt torque references. Everything works offline, because the machine that is broken is rarely parked next to a cell tower.

About

Who is behind it

Voltare is the studio of Kaleb Simpson, working from South Carolina. One engineer, with AI agents doing a lot of the typing and real hardware doing all of the checking.

The projects look unrelated: a language, an Android runtime, a compressor, a dock utility, an app for equipment technicians. What they share is the approach. Pick a problem worth solving, build the core yourself, and prove it works.
