Monjo runs two Anthropic frontier models simultaneously on your project — one sandboxed for deep reasoning and planning, one with full terminal and system access for execution. This workflow doesn't exist anywhere else.
No other AI coding tool runs two frontier models simultaneously on one codebase. Monjo separates intelligence from execution by design — one model thinks, one acts, both run at the same time.
This is not a coding assistant. Monjo is an autonomous agent with real system access — the gap between "suggests changes" and "ships them" is the entire point.
The sandbox model writes CSS, HTML, and design language code while simultaneously planning the JS logic for the exec model. The exec model handles all JavaScript, backend languages, and terminal commands. Both run at the same time — one builds the visual layer, one builds the logic layer.
The sandbox model maps your entire project — imports, dependency graph, build config, test suites — before touching a single file. It understands your architecture the way a senior engineer would.
Standard: file edits only. Elevated: + terminal, CMD, and package managers. Full: complete autonomous system control. Monjo operates exactly within what you grant.
At elevated bypass, the exec model has real shell access — npm, pip, git, compilers, test runners, build scripts, any CLI your project needs. It runs them, not simulates them.
Monjo is a native Windows Electron app. Your codebase is never uploaded, synced, or sent to any server. Only AI inference calls leave your machine.
Pair Monjo with Hasso Build and AI for a complete pipeline — from AI-generated site to production-ready codebase, all within one platform.
Both models fire simultaneously from the moment you start a session. The sandbox model never slows the exec model down — they operate in parallel, coordinating in real time.
Give Monjo an engineering brief in plain language. It treats it as a real task — not a chat message. Set your bypass level before execution begins.
The sandboxed model indexes the codebase, plans all changes, and immediately starts writing — CSS, HTML, design tokens, animations, component markup. The full visual layer, no terminal needed.
Simultaneously, the executive model receives the JS/TS plan and executes — writing application logic, backend code, running npm installs, build scripts, and any terminal commands the task requires.
The sandbox verifies exec output, catches logic errors, and adjusts styles to match new code structure — all in real time. Both models stay in sync throughout the entire session.
Monjo runs as a native Electron app. No Docker, no cloud dependencies, no setup beyond the installer.
