The flagship · v1.400.7

An AI operating system that lives on your machine.

Iron Jarvis plans, builds and reviews work with a team of agents — and asks before anything risky. 64 stars on GitHub, 400 releases and counting.

Flagship builds

Seven builds. Zero toy projects.

Each one solves a problem I hit myself — running an accounting practice, working with AI all day, or refusing to rent software I should own.

Iron Jarvis

Your own local-first AI operating system.

A desktop AI workspace that runs on your own computer. One chat box answers quick questions in seconds and quietly hands bigger jobs to a team of AI agents that plan, build and review the work. Every action is logged, risky steps ask first, and code changes wait for your approval before they merge.

QuickBooks MCP Desktop

Let AI agents keep QuickBooks Desktop books — safely.

QuickBooks Desktop has no modern API, so AI assistants cannot touch it. This server gives Claude, Cursor or any MCP-capable agent 150 accounting tools — customers, invoices, bills, payroll reports, bank reconciliation, journal entries — with dry-run previews, read-only sessions and rollback-safe batch posting, so an agent can work real books without wrecking them.

KarbonCopy

The whole accounting practice, on your own network.

A self-hosted practice-management system for accounting firms — work tracking, clients, time, billing, a client portal, e-signatures and a compliance calendar — that runs on one machine in the office instead of a vendor's cloud. Because it lives on the firm's network, it can watch the file server and react the moment a finished return lands.

Raster Studio

A Photoshop-class image editor. Your files stay local.

A native desktop image editor aiming at full feature and workflow parity with Photopea — the same menus, tools, panels and shortcuts — running entirely on your machine with no account, no cloud and no network calls. It opens and saves Photoshop PSD/PSB files with layers, masks, effects, text and smart objects, and reads more than 60 file types.

AI: The World of Intelligence

Level up in AI like an RPG talent tree.

A free learning platform that turns AI skills into a fantasy-RPG talent tree. Pick a class, spend talent points and level from “AI Civilian” to “Intelligence Architect”. Each of the 262 talents has a teaching prompt that turns any AI assistant into your trainer, a hands-on quest, and a trial where the AI examines you and scores the result.

IronCore

The coding agent that molds itself to local models.

Coding agents like Claude Code and Codex shine with frontier models but fall apart on a smaller open model you run yourself. IronCore flips the assumption: it first measures what your model can actually do, then moves the jobs small models are bad at — remembering goals, formatting tool calls, applying patches, knowing when to stop — into reliable code.

Iron-Proxy

All your AI subscriptions. Never hit a limit.

If you pay for several AI subscriptions you still hit “usage limit reached” mid-work. Iron-Proxy keeps an ordered list of your accounts per provider and, when one runs out, switches to the next account of the same provider mid-conversation — then switches back automatically when the first one resets. It signs in through each vendor's official tools and never moves your data to a different provider.

The Lab · in progress

Still on the bench. Already serious.

Work in progress, shown honestly — with the test counts to prove it. The biggest one: a Photoshop-class image editor written from scratch in Rust.

Learning platform · live

I turned learning AI into an RPG.

AI: The World of Intelligence is a free talent tree with 262 skills, 10 classes and 100 levels. Every talent ships a teaching prompt that turns any AI into your trainer, a quest, and a trial where the AI examines you. Try the real core tree right here — click a talent to spend a point.

Built by an accountant

Software that balances.

I'm a licensed CPA first. That's why my agents can't post a journal entry they haven't previewed, can't file anything without a human, and keep every dollar in exact decimal math. Try it: approve the entry below.

Private AI · on hardware I own

Client data never takes the scenic route.

An accounting practice can't spray client records across cloud APIs. So the stack is built to run on two NVIDIA DGX Sparks I own — and my apps are designed to refuse, by name, rather than silently fall back to a cloud model.

  • Spark Landing Kit turns two DGX Sparks into an OpenAI-compatible service behind eight pass/fail gates.
  • reap-lab prunes idle experts out of big models so they fit — and refuses to install one that drops below 95% quality.
  • IronCore measures what a local model can honestly do before trusting it with your code.
