The intelligence layer

Aria is the difference between using apps and commanding a system.

One assistant runs across every window — reading your document, your sheet, your timeline, your codebase — and acting on it. Local-first, model-transparent, and only ever working from data you own.

Real software

Not slides. Running apps.

These are real Culltron windows — Office, Studio, Diagram, Slides and Video — each with Aria woven through the workspace.

Always-on security

Sentinel watches every process.

Sentinel is designed to inspect what each model can see, where data moves, and which process asked. Launch controls keep agent actions gated until the runtime is approved.

How it holds together

One system. Six guarantees.

Local-first models

Run on your machine or your own keys. Nothing leaves unless you send it.

Aria command layer

Point one intelligence at any document, project or window across the OS.

Sentinel security

Runtime protection on by default, watching every process across the system.

Model-transparent

Always know which model is running, where it runs, and what it can see.

One file space

Every app reads and writes a space you own — no silos, no lock-in.

Operate anywhere

Built for offline, low-bandwidth and the edge — useful when the signal drops.

Two tiers

Max ships the apps. Ultra adds Aria.

Ultra X26

Aria, built in.

Every Max app, plus Aria running natively across the workspace — a local-first command layer you can point at any document, project or window.

✓All Max applications included
✓Aria native in every app
✓Local-first models, your keys
✓Sentinel runtime security
M Max

The professional suite.

Every Culltron pro app at full power. Bring Aria in when you want it — Max focuses on the tools, not a built-in AI command layer.

✓Full professional app suite
✓Aria available as an add-on
✓Offline-first file ownership
✓Upgrade to Ultra anytime

Both tiers are offline-first and keep your files on your machine. Aria runs against a local model or a key you control.
