AI That Lives
on Your Device.

Mulberry runs a local AI model directly on your hardware — no internet required. For heavier tasks, bring your own API key. On-device brain tuning adapts to how you work. No middleman. No data harvesting. No surprises.

Typical AI IDEs

Your code goes to their servers. They train on it. No local model. No choice.

Mulberry

Local model on-device. BYOK for cloud. Brain tuning that learns you. Nothing leaves unless you choose.

// Under the Hood

Three Principles, Zero Compromise

Every design decision starts with the same question: does the user stay in control?

// Local Model + BYOK

AI That Runs Where Your Files Live

A local model runs inference directly on your device — instant, private, no network. For tasks that need more power, bring your own API key and connect to the cloud model you trust. Requests go device-to-API, no proxy, no middleman. On-device brain tuning learns your patterns and adapts over time.

Write and Preview Without a Connection

Mulberry caches CDN scripts locally — React, Babel, Tailwind — so you can develop and preview on airplane mode. Write JSX, see it render. Edit Python, see it execute via Pyodide. Open a 3D model. All without a single network request.
