Your assistant.
Your rules.

Mark IIII is HIOSI software that lets you create and operate your own personalized digital assistant on your Windows computer. You name it. You shape its personality. You decide — folder by folder, file by file — exactly what it's allowed to touch. And it keeps a receipt for everything it does.

// The four principles

Built on control, not blind trust

Most AI assistants ask you to hand over your computer and hope for the best. Mark IIII is designed the other way around — every boundary is explicit, every action is approved, and nothing is ever silently changed.

PRINCIPLE 01

You control the identity

Name, role, greeting, personality, theme, accent colour — the assistant is yours, not a fixed mascot.

PRINCIPLE 02

You control folder access

No folder is ever authorized automatically. You grant access through the native Windows picker, and you can revoke it any time.

PRINCIPLE 03

Actions require approval

File-changing work starts as a proposal. Nothing runs, copies, or builds until you explicitly approve it.

PRINCIPLE 04

Originals are preserved

Files are copied, never moved or overwritten. Every completed action produces a versioned receipt for audit.

// Meet Huxley — then replace him

One product. Any assistant you can imagine.

Huxley is HIOSI's public reference assistant — the demonstration of what Mark IIII can do. But Mark IIII isn't Huxley. It's the machinery for making your own.

The default profile that ships with Mark IIII. Huxley shows you the floater, the dashboard, the task proposals, and the safety model in action — then steps aside.

Yours

Created by you, for your work

A researcher, an editor, a studio manager, a shop assistant — configure the name, role, traits, and look, and it runs on the same safe operational foundation.

// What it does today

The working foundation

Desktop floater & dashboard

A small always-there assistant floater with quick access to tasks, proposals, and the full dashboard: Home, Tasks, Files, Create Assistant, Permissions.

Task proposals

Describe a task and it's stored as a controlled proposal — approve or cancel, with state preserved between sessions.

Approval-gated file intake

Select files from authorized folders, approve the intake, and a copy lands in the assistant's isolated inbox — original untouched, receipt issued.

File search & navigation

Search authorized folders and the assistant's workspace by name; open results or reveal them in Explorer — never outside approved boundaries.

The Forge coding engine

Hand it a written spec and it builds Python tools locally — generating, running, and iterating up to five attempts in an isolated job folder, every attempt logged. Powered by a local model: no cloud AI, no per-use cost.

Receipts for everything

Completed actions produce versioned JSON receipts, stored and auditable. If it happened, there's a record.

Where it stands, honestly: Mark IIII is in its functional-foundation stage and heading into production. The permission system, proposal workflow, file intake, search, and the Forge engine are working today. Conversation, natural-language task execution, long-term memory, and companion apps are on the roadmap — planned capabilities, not current claims. When we say it does something, it does it.

// Where it's headed

The road to release

NOW

Production build-out. Inbox browsing and filing, project registration without copying, safe delivery of fresh copies to folders you choose — with full receipts and history.

NEXT

The retrieval workflow. "Take me there" source-project recovery, duplicate detection, and reversible quarantine — finding and organizing your work without ever endangering it.

LATER

The full assistant. Conversation, natural-language task execution, notebook memory, and companion apps — all on the same approval-first foundation.
