// Inspect it. Define it. Own it.

Your AI.
Not theirs.

Personal AI Studio.

Apple's AI reads your screen, calendar, and email — with no way to see what it decides or where it sends your data. See inside the model, set the rules, keep the audit log. On iOS & macOS. Free to start.

// Core Capabilities

Everything You Need,
Nothing You Don't

A personal AI studio that respects your privacy by default — not as an afterthought.

lock

Privacy by Architecture

No accounts to create. No analytics running in the background. No cloud sync unless you choose it. Your files stay on your device — iOS sandbox or macOS app container — period.

smart_toy

On-Device AI + BYOK

A local model runs directly on your device — no network needed, no data sent. For heavier tasks, bring your own API key and choose your cloud model. On-device brain tuning adapts to how you work over time.

code

Offline Rendering Engine

Renders React, JSX, TypeScript, HTML, and CSS without a build server. Babel transpiles at runtime. CDN scripts are cached locally for airplane-mode development.

edit_note

Code Editor + Versioning

Native editor with syntax highlighting and auto-completion. Git-style save points let you snapshot, diff, and restore — no git required.

view_in_ar

3D Model Viewer

Open .usdz, .glb, .gltf, .obj, and .dae files natively on iOS. Rotate, zoom, inspect — no third-party app needed.

cloud_sync

Persistent Remote Sessions

Magnum Brain Tuning tier includes tmux-backed SSH sessions to your Mac orchestrator. Sessions survive network disconnects, sleep, and app restarts. Send a task from your phone and get notified when it's done.

You Own Your Data

Every AI interaction is logged locally and exportable. Chat history, prompts, responses — it's your data, stored on your device, available to you on demand.

// Getting Started

Simple by Design

No sign-up flow. No onboarding survey. Open the app and start working.

01

Open Files

Point Mulberry at any folder on your device — iOS Files or macOS Finder. It discovers and indexes your project instantly.

02

Edit + Render

Write code in the native editor. Preview renders live — React, Markdown, HTML, Python output, 3D models.

03

Stay in Control

Save points track your changes. AI assists when you ask. Everything stays on your device unless you decide otherwise.

// See It Run

Don't Take Our Word.
Watch It Work.

Real footage from real devices. No mockups, no simulations.

AI Assistant — Live

Ask a question. Get an answer. On-device, no cloud round-trip.

Real Use Case — Resume Builder

Build a resume from scratch using AI assistance — entirely on your phone.

// On Sharing

Personalize First.
Share When You're Ready.

Most tools start with collaboration and never get around to making the individual experience good. We went the other direction.

person

Your Workspace First

Mulberry tunes to how you work — your file types, your AI preferences, your patterns. A tool that doesn't know you has nothing worth sharing.

publish

Share Direct, Not Through Third Parties

Session sharing is direct — no data leaves the Mulberry ecosystem. Unlike tools that leak collaboration data through Slack or Discord, Mulberry keeps it private. Export signed project packages, share sessions with teammates (Magnum Brain Tuning + Team tier), or AirDrop locally. No server in between.

handshake

Open Where It Counts

We're committed to opening the components that earn your trust — file parsers, rendering engines, offline caching. Inspect how we handle your data. The AI layer and personalization engine stay proprietary because that's what makes Mulberry yours.
